16 Common Table Tennis injuries (Prevention & Treatment)

16 common table tennis injuries: wrist sprains, rotator cuff impingement, ankle sprains, knee tendonitis and tennis elbow.

The repetitive stroke pattern drives most of them, so overuse injuries, back and neck strain, blisters and eye injuries from ball impact are covered too, each with causes and prevention pointers.

Injury Rates and Numbers

The figures below come from injury surveillance data and peer reviewed studies. Each row names the population it was measured in, because rates from elite athletes and from recreational players are not comparable.

Wrist injuries (sprains, strains)

The rapid forearm rotation and wrist snap that generates topspin loads the extensor and flexor tendons at the wrist as well as the triangular fibrocartilage complex on the little finger side of the joint. A sprain means the ligaments holding the small carpal bones together have been overstretched, usually after a fall or a blocked shot; a strain means the muscle tendon units that flex or extend the wrist have been overloaded. In table tennis the strain pattern is far more common because the same snapping motion is repeated thousands of times per session.

Symptoms

• Pain on the thumb side or little finger side of the wrist when you brush the ball for spin
• A weaker, less certain grip on the handle
• Aching that lingers after training instead of settling within an hour
• Swelling or a puffy feeling across the back of the wrist
• Clicking or catching when you rotate the forearm

How serious it is: Sprains are graded 1 to 3: grade 1 is a stretched ligament with pain but a stable joint, grade 2 a partial tear with more swelling and some instability, grade 3 a complete tear. Strains follow the same scale, and the practical difference is whether you can still hold and rotate the paddle without giving way.

Typical time out: Two to four weeks for a grade 1 strain or sprain with modified play, six to twelve weeks for a partial tear, and three months or more if a ligament or the cartilage complex is torn and needs surgical repair. The range is wide because wrist pain from a tendon overload settles far faster than damage to the cartilage disc, which has a poor blood supply.

See a doctor if: See a doctor if the wrist looks deformed, if you cannot turn your palm up and down, or if you have numbness or pins and needles in the fingers.

What helps

• Keep playing at a level that stays below a mild, settling pain rather than stopping completely, and cut the number of heavy topspin loops first
• Progressive loading of the wrist extensors and flexors with a light dumbbell or band, starting isometric and moving to slow controlled repetitions
• Check the grip size and blade weight, since a handle that is too thin forces a tighter grip and more wrist work
• A taping strip or a soft support for match play only, not as a permanent crutch
• Imaging if pain sits on the little finger side and clicks with rotation for more than six weeks, because the cartilage complex needs a different plan

Shoulder injuries (rotator cuff, impingement)

The four rotator cuff tendons, mainly supraspinatus, hold the head of the upper arm bone centered in the socket during the fast forehand loop and the serve. When they fatigue, the head drifts upward and the tendon plus the bursa above it get compressed under the bony roof of the shoulder, which is what impingement means. Backhand play and blocking add repeated internal rotation that shortens the front of the joint and makes the pinch more likely.

Symptoms

• A painful arc when you lift the arm to about shoulder height
• Pain at the outer upper arm rather than at the top of the shoulder
• Trouble reaching behind your back or up to a high shelf
• Loss of speed on the forehand before any real pain appears
• Aching at night, especially when you lie on that side

How serious it is: The mild form is tendon irritation with pain only at the end of range, the moderate form is a partial thickness tear with weakness, and the severe form is a full thickness tear where the arm cannot be held out to the side against gravity. Age matters: in players over forty a tear is more likely than pure irritation.

Typical time out: Six to twelve weeks of guided loading for tendon irritation and most partial tears, and four to six months before full training after a surgical repair. The spread comes from whether the tendon is only irritated or actually torn, which is not something you can tell from pain alone.

See a doctor if: Get it checked if you cannot hold the arm out sideways after a fall, or if pain wakes you every night for more than two weeks.

What helps

• Loaded rotator cuff and scapular work three times a week, external rotation with a band and low rows, taken to fatigue rather than done as a warm up token
• Reduce serving and high loop volume for a few weeks while keeping footwork and blocking drills
• Work on trunk rotation and hip drive, because a shoulder that has to produce all the power on its own gets overloaded
• Physiotherapy early if weakness rather than pain is the main sign
• Corticosteroid injection only as an exception when pain blocks all rehab, since it eases pain in the short term but tends to leave tendons worse off over months

Ankle sprains

The side to side shuffle and the lunge for a wide ball put the foot in a position where it can roll inward under load, stretching the anterior talofibular ligament on the outside of the ankle first. Slippery or sticky spots on the floor, or catching a foot on the table leg or a barrier, turn a normal step into a sprain. The inside ligament and the high ankle ligaments are hit far less often in this sport.

Symptoms

• Sharp pain on the outside of the ankle at the moment of the roll
• Swelling that appears within an hour, often with bruising a day later
• Feeling unsteady when you push off sideways
• Pain when you put weight on it, most of all on uneven ground
• Stiffness the following morning

How serious it is: Grade 1 is a stretched ligament with mild swelling and normal walking, grade 2 a partial tear with clear swelling and a limp, grade 3 a complete tear with marked instability. Even a grade 1 leaves the joint position sense impaired, which is why untreated sprains keep coming back.

Typical time out: One to three weeks for a grade 1, three to six weeks for a grade 2, and eight to twelve weeks or more for a grade 3. The long tail is not the ligament healing but the balance and strength work needed before quick lateral movement is safe again.

See a doctor if: See a doctor if you cannot take four steps on the leg, or if pressing on the bony point of the ankle or the base of the little toe is exquisitely painful, because that suggests a fracture.

What helps

• Start walking and loading as soon as pain allows rather than immobilizing, since early movement speeds the return
• Single leg balance work, first on the floor, then on a soft pad, then with a ball toss, carried on for at least six weeks
• Calf and peroneal strength work, because the muscles on the outside of the shin are the active brake against rolling
• A brace or tape for the first months back in competition, which measurably lowers the chance of a repeat sprain
• Short cooling in the first hours if pain is severe, then move on to gentle loading

Knee injuries (tendonitis, meniscus)

The low, wide stance and the constant small hops load the patellar tendon between the kneecap and the shin bone, which reacts to repeated high loads with a tendinopathy rather than a classic inflammation. The meniscus, the two cartilage wedges that cushion the joint, is at risk when the knee is bent deeply and the body rotates over a planted foot, which happens on the lunge into the wide forehand corner. Older players often have a degenerate meniscus that tears with very little force.

Symptoms

• Pain at a defined point just below the kneecap that warms up during play and returns afterward
• Pain going down stairs or standing up after sitting
• A catching or locking feeling in the joint with a meniscus problem
• Swelling that builds hours after play rather than immediately
• Trouble holding the deep ready position

How serious it is: Patellar tendinopathy runs from pain only after play, through pain at the start that eases, to pain that stays through the whole session and marks the point where the load must come down. Meniscus tears range from a small stable tear that settles with strength work to a displaced tear that blocks full extension and usually needs a surgeon.

Typical time out: Three to six months of progressive loading for a settled patellar tendinopathy, three to eight weeks for a small stable meniscus tear treated conservatively, and three to four months after a meniscus repair, though a trimming procedure is quicker. Tendon problems take longest because tendon tissue adapts slowly.

See a doctor if: See a doctor if the knee locks and will not straighten, gives way under you, or swells tightly within a couple of hours.

What helps

• Heavy slow resistance or eccentric work for the quadriceps, for example slow decline squats, is the core treatment for patellar tendinopathy and beats rest
• Load management with a pain monitoring rule: pain during the session up to a mild level is acceptable if it settles by the next morning
• Hip and calf strength, since a weak hip lets the knee fall inward on every lunge
• Physiotherapy if pain persists beyond six weeks or the knee gives way
• Imaging when the knee locks or the swelling is rapid, not for routine tendon pain

Elbow injuries (tennis elbow)

Tennis elbow, or lateral epicondylalgia, is a degenerative change in the common extensor tendon where it attaches to the bony bump on the outside of the elbow, above all in the extensor carpi radialis brevis. Gripping the handle tightly while snapping the wrist for spin makes these muscles work as brakes hundreds of times a session. Golfer’s elbow, the same problem on the inside of the elbow, shows up in players who serve and loop with a heavy forearm rotation.

Symptoms

• Tenderness at a small point on the outside of the elbow that you can put a fingertip on
• Pain when you lift a kettle or shake hands
• Grip that tires quickly and feels weak
• Pain that starts after play and moves earlier into the session over weeks
• Stiffness in the forearm in the morning

How serious it is: The mild form hurts only after loading and settles overnight, the moderate form hurts during play and with daily gripping, and the stubborn form has been present for more than six months with visible tendon change on ultrasound and needs a long, structured loading plan.

Typical time out: You rarely stop playing altogether. Expect six to twelve weeks of modified play for a recent case and six months to a year for a case that has been ignored for a long time. The long form is why early treatment matters more here than in most injuries.

See a doctor if: Get it looked at if you have numbness or weakness in the hand, or if the pain sits over the joint line rather than the bony bump, because that is a different problem.

What helps

• Progressive wrist extensor loading, starting with isometric holds and moving to slow eccentric lowering with a light weight, done daily over months
• Loosen the grip pressure between rallies and check the handle size, since a death grip is the main driver
• Strengthen the shoulder and upper back so the forearm is not the only source of control
• A forearm strap below the elbow can cut pain during play, but it does not heal anything on its own
• Corticosteroid injection is an exception, not a first step: it helps for weeks and is associated with worse outcomes at one year than loading

Back injuries (muscle strains)

The flexed, forward leaning ready position holds the lumbar spine in one loaded posture for long periods, while every forehand adds a rotation through the trunk. The strain itself sits in the erector spinae and the quadratus lumborum, the muscles running alongside the spine, and the small facet joints at the back of the vertebrae also get irritated by the repeated rotation and extension of the serve. Long tournament days on a hard floor add to the total load.

Symptoms

• A dull band of pain across the lower back after a long session
• Stiffness when you straighten up out of the ready position
• A sharp catch when you twist quickly into a wide forehand
• Muscles that feel tight and guarded on one side
• Pain relieved by walking and made worse by standing still bent over

How serious it is: A simple muscle strain is painful and stiff but the pain stays in the back and settles within days to a couple of weeks. It becomes a different matter when pain runs down a leg past the knee, which suggests nerve involvement rather than a muscle problem.

Typical time out: Three days to three weeks for a straightforward muscle strain, and six weeks or more if a disc or a facet joint is involved. Most back strains improve fastest when you keep moving, so the range depends more on how quickly you return to gentle activity than on the tissue itself.

See a doctor if: Get urgent help for numbness in the saddle area, loss of bladder or bowel control, leg weakness, or back pain with fever.

What helps

• Stay active and return to light play early, since prolonged rest makes back pain worse rather than better
• Build hip and trunk strength, particularly hip extension and anti rotation work, so the spine is not the main hinge in the stroke
• Break up long sessions with standing extension and short walks instead of staying bent over for two hours
• Raise the ready position slightly and use the legs more, as a very deep static crouch loads the lumbar spine for the whole session
• Physiotherapy if the same episode keeps returning every few months

Hand injuries (blisters, sprains)

Blisters form where the handle shears against the skin of the palm and the web between thumb and index finger, so the top layer of skin separates from the layer below and fills with fluid. Sprains in the hand involve the ligaments of the thumb base or the small joints when a ball or a fall drives a finger sideways. In penhold grip the pressure sits on a different, smaller area of skin, which is why the blister pattern differs from shakehand players.

Symptoms

• A hot, burning patch on the palm that turns into a fluid filled bubble
• Raw skin after the blister roof tears
• Pain at the base of the thumb when you pinch or grip
• Swelling around one small joint
• A grip that you keep adjusting because one spot hurts

How serious it is: Blisters are a nuisance unless the roof tears and the base becomes infected, which turns a minor problem into a medical one. Thumb base sprains follow the usual 1 to 3 scale, and a complete tear of the ulnar collateral ligament at the thumb often needs surgical repair because the ends will not heal in place.

Typical time out: Blisters cost three to ten days of comfortable play and often none at all with padding. A thumb or finger sprain costs two to six weeks, and a complete thumb ligament tear needs six to twelve weeks after repair.

See a doctor if: See a doctor if the skin around a blister turns red and spreads, if there is pus or fever, or if a thumb feels unstable when you pinch.

What helps

• Leave an intact blister roof in place and cover it with a hydrocolloid dressing, which is both padding and a sterile cover
• Fix the cause rather than the skin: change the grip tape, adjust handle thickness, or sand a sharp edge on the blade
• Buddy tape a sprained finger to its neighbor for a few weeks while keeping it moving
• Get a thumb base injury assessed rather than taping it blind, since a missed complete tear leaves a permanently weak pinch
• Return to gripping early with reduced session length rather than resting the hand completely

Overuse injuries (from repetitive motion)

Overuse is not one injury but a pattern: tendon, bone or muscle receives more load than it has time to adapt to, so the tissue degrades faster than it rebuilds. In table tennis the usual targets are the wrist extensors, the patellar and Achilles tendons, the rotator cuff and the lumbar muscles, because those structures repeat the same short range movement thousands of times per session. Multi ball training and long tournament blocks are the classic trigger, since load rises quickly without a matching rise in recovery.

Symptoms

• Pain that begins after training, then earlier and earlier in the session over weeks
• Morning stiffness in the affected area that eases with movement
• A gradual loss of power or accuracy with no single injury moment
• Tenderness at a defined point rather than a diffuse ache
• Symptoms that flare after a heavy week and quiet down after a light one

How serious it is: The useful ladder is: pain after activity only, pain during activity that does not affect performance, pain during activity that does affect performance, and pain in daily life. The first two steps respond well to load adjustment; the last two usually need a structured rehab plan and take much longer.

Typical time out: Six weeks to six months, depending on which tissue is involved and how long the problem was ignored. Tendons and bone stress reactions sit at the long end because both adapt slowly, while muscle overload settles in weeks.

See a doctor if: See a doctor if the pain is at one point on a bone and hurts when you hop on that leg, which raises the question of a stress fracture.

What helps

• Change training load in steps of roughly ten percent per week rather than adding a whole extra block at once
• Keep a simple log of hours and heavy sessions, since most overuse problems become obvious in hindsight from a sudden jump
• Progressive loading of the painful tissue instead of avoidance, using a pain monitoring rule that allows mild pain that settles by morning
• Build in genuinely light weeks after tournaments, and sleep, since tissue repair happens between sessions
• Imaging when pain is localized to bone, unchanged after six weeks of sensible loading, or wakes you at night

Eye injuries (from ball impact)

A ball travelling at speed, or more often an edge of the paddle or a collision with a partner in doubles, can strike the eyeball and the surrounding bone. The forces can bruise the eyeball itself, tear the iris, cause bleeding into the front chamber of the eye, or fracture the thin floor of the eye socket. The light ball makes serious injury uncommon compared with racquet sports played with a harder ball, but a paddle edge to the face is a real risk in doubles.

Symptoms

• Blurred or double vision after the impact
• Pain when moving the eye or looking upward
• Visible blood in the colored part of the eye
• Light sensitivity and watering
• Numbness of the cheek or upper lip on that side

How serious it is: A simple bruise to the lids and surrounding skin settles by itself. Blood in the front chamber of the eye, a pupil that is no longer round, double vision or restricted eye movement are all signs of a serious injury that needs same day specialist assessment.

Typical time out: A few days for a lid bruise, two to four weeks of no play after bleeding in the eye because of the rebleeding risk, and six weeks or more after an orbital fracture or a surgical repair.

See a doctor if: Any change in vision, an irregular pupil, blood inside the eye or pain on eye movement means the same day emergency department, not a wait and see.

What helps

• Stop play immediately and cover the eye without pressing on the globe
• Same day assessment by an eye specialist for anything beyond a superficial lid bruise
• Polycarbonate protective eyewear for players who already have vision in only one functional eye or who play a lot of doubles
• Do not rub the eye and do not use eye drops that were not prescribed for this injury
• Agree on doubles movement patterns so partners are not crossing into the same space at the table

Foot injuries (sprains, strains)

The push off, stop and pivot on the forefoot loads the plantar fascia along the sole and the small muscles of the arch, and the metatarsal bones take repeated impact on a hard floor. Plantar fasciopathy at the heel and forefoot pain under the ball of the foot are the two typical presentations, while a true sprain of the midfoot joints follows a landing on a rolled or twisted foot. Worn out shoes with a flattened sole are a frequent contributor because the shock and the grip both change.

Symptoms

• Sharp pain under the heel with the first steps in the morning
• Burning or aching under the ball of the foot late in a session
• Pain when you push off sideways
• Tenderness when you press along the arch
• Swelling on the top of the foot after a twist

How serious it is: Soft tissue pain that eases as you warm up and returns later is the common, manageable form. Pain that stays sharp at one point on a bone, hurts when you hop and does not warm up is the pattern that raises the question of a stress fracture and is a different problem altogether.

Typical time out: Two to six weeks for a midfoot sprain or an arch strain, three to twelve months for stubborn plantar fasciopathy with modified play throughout, and six to eight weeks of no impact for a confirmed metatarsal stress fracture.

See a doctor if: See a doctor if a single point on a bone hurts when you hop on that leg, or if you cannot bear weight after a twist.

What helps

• Replace indoor shoes on a schedule rather than when they look worn, since the midsole loses its properties before the upper does
• Progressive calf raise loading, including with the toes propped on a book, which is the best supported treatment for heel pain
• Shorten the footwork drills and cut jumping volume for a few weeks while keeping stroke practice
• A supportive insole can reduce heel pain during the loading phase, though it is a helper and not the treatment
• Physiotherapy if heel pain has been present for more than three months, because these cases rarely resolve on their own

Neck injuries (muscle strain)

The head is held forward and slightly down to track the ball for hours, which loads the deep neck extensors and the upper trapezius as static holders rather than movers. Muscles held at a constant low level of tension fatigue and become painful without any single injury moment, and the small facet joints of the cervical spine are irritated by the same sustained posture. Quick head turns to follow a wide ball can add an acute strain on top of the fatigued tissue.

Symptoms

• A tight, aching band across the top of the shoulders and the base of the skull
• Headache that starts at the back of the head and spreads forward after a long session
• Limited turning of the head to one side
• Pain when you hold the head forward for long
• Tenderness when someone presses the muscle beside the spine

How serious it is: A postural strain is stiff and painful but the pain stays in the neck, shoulders and head. Pain that radiates into the arm with numbness or weakness points to nerve irritation and is a separate matter that should be assessed.

Typical time out: A few days to two weeks for a postural strain, and four to eight weeks if a facet joint or a nerve root is involved. Most players keep playing at reduced volume throughout.

See a doctor if: Get it checked if you have numbness, tingling or weakness in an arm, or a headache after a fall or a blow to the head.

What helps

• Loaded neck and upper back strength work, including deep neck flexor holds and rows, because endurance is what protects a static posture
• Break long sessions with a minute of looking up and rolling the shoulders instead of two unbroken hours of forward gaze
• Check lighting and glare, since squinting adds to the forward head posture
• Short heat and gentle movement rather than a collar, because immobilizing a strained neck slows recovery
• Physiotherapy if headaches keep coming back after every session

Hip injuries (strains)

The lunge to a wide ball and the repeated side step load the hip adductors on the inner thigh and the hip flexors at the front, both of which act as brakes at the end of the movement. Adductor strain is the classic pattern because the muscle is lengthening while contracting hard as the leg reaches sideways. Deeper hip pain in the groin that catches on rotation can come from the joint itself rather than the muscle, particularly in players who spend a lot of time in a deep flexed stance.

Symptoms

• A pulling pain in the inner thigh or groin during a wide lunge
• Pain when you squeeze your knees together
• Stiffness at the front of the hip after sitting
• A pinch deep in the groin when you rotate into the shot
• Reduced reach on one side without any obvious swelling

How serious it is: Adductor strains are graded 1 to 3: grade 1 means pain with a normal contraction, grade 2 means a partial tear with clear weakness and often bruising, grade 3 a complete tear or an avulsion from the bone. Groin pain from the joint rather than the muscle behaves differently and does not respond to muscle rehab alone.

Typical time out: Two to four weeks for a grade 1 adductor strain, six to twelve weeks for a grade 2, and three months or more for a complete tear or a hip joint problem needing surgery. Groin injuries have a high reinjury rate, which is why the return should be based on regained strength and not on pain alone.

See a doctor if: See a doctor if you felt a pop with sudden weakness, if you cannot bear weight, or if deep groin pain catches and clicks with rotation.

What helps

• The Copenhagen adduction exercise or a similar heavy adductor program, which both treats and prevents groin strains
• Widen the movement range gradually in training, since the injury happens at the extreme of the lunge
• Hip flexor and hip rotator mobility work if the front of the hip is tight from long sessions in a crouch
• Return to full lunging only when the injured side squeezes close to the strength of the other side
• Imaging if deep groin pain persists past six weeks despite muscle work, because that points at the joint

Finger injuries (sprains, strains)

The collateral ligaments and the volar plate at the middle joint of a finger are damaged when the finger is bent sideways or backward, usually by a ball, a fall onto the hand or a knock against the table edge. In penhold players the index and middle fingers curl around the blade for long periods, which can also irritate the flexor tendons and their sheaths. Sprains here are far more common than fractures, but the two look similar in the first hours.

Symptoms

• Immediate pain at one knuckle after the knock
• Swelling that makes the joint look thicker within minutes
• Difficulty fully straightening or bending the finger
• Pain when the finger is pushed sideways
• A grip that no longer sits the same on the handle

How serious it is: Grade 1 and 2 sprains keep the joint stable and settle with taping and movement. A joint that opens up when stressed sideways, a finger that will not straighten actively, or an obvious angulation means a complete ligament tear, a tendon avulsion or a fracture and needs an x ray.

Typical time out: You can usually keep playing. Full comfort returns in two to six weeks for a simple sprain, six to ten weeks if a tendon or the volar plate is involved, and longer after a fracture. Fingers stay swollen and slightly stiff for months even after the injury has healed, which is normal.

See a doctor if: Get an x ray if the finger looks crooked, if you cannot actively straighten the tip, or if the joint feels loose when pushed sideways.

What helps

• Buddy tape to the neighboring finger and keep moving the joint, since stiffness is the main long term problem
• Start gentle bending and straightening within a few days rather than splinting for weeks
• Adjust grip tape or handle shape if a specific finger is repeatedly loaded
• Hand therapy if the joint is still noticeably stiff after four weeks
• Short cooling in the first hours for pain, then movement

Head injuries (concussions, from falling)

Concussion is a functional disturbance of the brain caused by a blow to the head or a force transmitted through the body, not a structural bruise that shows on a routine scan. In table tennis it comes almost entirely from falls during a lunge, collisions with the table corner or a barrier, or a clash of heads in doubles. Because the ball itself is light, the danger is the floor and the furniture, not the equipment.

Symptoms

• Headache, pressure in the head or a dazed feeling after the impact
• Dizziness or trouble with balance
• Nausea, blurred vision or sensitivity to light and noise
• Feeling slowed down, foggy, or unable to concentrate
• Being unusually irritable or emotional, or sleeping badly in the following nights

How serious it is: There is no useful mild or severe grading applied on the day. Any suspected concussion means the player stops for that day, and the difference that matters is between a concussion that resolves within a couple of weeks and symptoms that persist beyond four weeks, which needs specialist input.

Typical time out: A minimum of one to two weeks with a stepwise return, and four weeks or more if symptoms persist. Return follows symptom resolution through graded steps, not the calendar, and a second impact before recovery is complete carries real risk.

See a doctor if: Call emergency services for loss of consciousness, repeated vomiting, a seizure, worsening headache, confusion that deepens, weakness on one side or clear fluid from the nose or ear.

What helps

• Remove the player from play the same day, with no return that session under any circumstances
• Relative rest for the first day or two, then light aerobic activity such as walking or a stationary bike below the symptom threshold, which speeds recovery compared to full rest
• Reintroduce screens, reading and work gradually rather than sitting in a dark room for a week
• Stepwise return to training with a day at each level and a step back if symptoms return
• Medical clearance before full contact with other players and before competition

Heat exhaustion/heat stroke

Heat exhaustion happens when fluid and salt losses through sweat outpace what you drink, so blood volume falls and the circulation struggles to supply both muscles and skin. Heat stroke is a different and far more dangerous state in which core temperature rises above roughly 40 degrees Celsius and the brain stops working normally. Table tennis halls are often poorly ventilated because windows and fans have to stay shut so the ball is not disturbed, which is exactly the setup for heat problems during long tournament days.

Symptoms

• Heavy sweating with weakness and light headedness
• Headache, nausea and muscle cramps
• Skin that feels clammy and a fast pulse
• Confusion, slurred speech or strange behavior, which points at heat stroke
• Collapse or loss of consciousness

How serious it is: Heat exhaustion leaves the player unwell but mentally clear and it settles with cooling and fluids. Any confusion, agitation, seizure or reduced consciousness in a hot player is heat stroke, a medical emergency in which minutes of delay in cooling change the outcome.

Typical time out: A day or two after uncomplicated heat exhaustion once fluids and salts are replaced, and several weeks under medical guidance after heat stroke, because heat tolerance takes time to recover.

See a doctor if: Confusion, agitation, seizure or collapse in a hot, exhausted player means call emergency services and start cooling immediately.

What helps

• Get the player out of the hall to a cool place, remove excess clothing and start cooling with cold water, wet cloths and air movement
• For suspected heat stroke, cool first and transport second: whole body cold water immersion is the most effective method available
• Drink to thirst across the whole tournament day and include salt, not just water, when sessions run long
• Plan a cooler space and a fan outside the playing area for multi day events
• Treat poor sleep, illness and a recent hot spell as extra risk and reduce the day’s load accordingly

Sunburn (for outdoor play)

Ultraviolet B radiation damages the DNA in the outer layer of skin cells, and the redness that appears hours later is the inflammatory response to that damage. Outdoor tables mean long sessions with the face, neck, forearms and the back of the playing hand exposed at midday, and light concrete or sand around the table reflects extra UV upward onto areas that shade normally protects. The damage accumulates across a lifetime and does not reverse.

Symptoms

• Skin that turns red and feels hot four to six hours after play
• Tenderness when clothing or a bag strap touches the area
• Tightness and itching as the burn peaks the next day
• Peeling several days later
• Blistering, chills or nausea after a severe burn

How serious it is: A first degree burn is red and sore and heals without a scar in a few days. Blistering means a deeper, second degree burn, and a burn with fever, chills or widespread blistering needs medical review.

Typical time out: None for a mild burn beyond staying out of the sun, and three to seven days of no outdoor play for a blistering burn while the skin closes.

See a doctor if: See a doctor for widespread blistering, fever or chills, or if you feel faint after a bad burn.

What helps

• Broad spectrum SPF 30 or higher applied generously before play and reapplied every two hours, plus a stick formula for the nose and ears
• A cap with a brim and a light long sleeved shirt, which outperform any sunscreen for the areas they cover
• Schedule outdoor sessions for the early morning or late afternoon rather than the middle of the day
• Cool showers, a bland moisturizer and an oral anti inflammatory for comfort while a mild burn settles
• Leave blisters intact and keep them covered rather than opening them

First Aid for Soft Tissue Injuries: PEACE and LOVE

Sports medicine has moved on from RICE. The current guidance, published in the British Journal of Sports Medicine in 2019, splits care into the first days after the injury and everything that follows.

PEACE, the first two to three days

• Protect: unload the area and limit movement that hurts, but only briefly.
• Elevate: keep the limb above heart level when you can.
• Avoid anti-inflammatories: they may blunt the healing you need.
• Compress: a bandage or taping limits swelling.
• Educate: your body heals this on its own; passive treatments rarely speed it up.

LOVE, from day three onward

• Load: return to movement as pain allows, early loading builds tissue.
• Optimism: expectations shape recovery more than most people assume.
• Vascularization: easy cardio that does not hurt brings blood to the area.
• Exercise: restore strength, mobility and balance before returning to play.

Ice still helps with pain in the first hours. What changed is the evidence that long icing and routine anti-inflammatory drugs slow tissue repair.

How to Lower Your Risk in Table Tennis

• Raise training volume in small steps and keep multi ball blocks separate from long match play in the same session, since most table tennis complaints come from a sudden jump in hours rather than from one bad movement.
• Train the shoulder rotators, upper back and grip with real resistance twice a week, because the forehand loop asks these small muscles to control a fast rotation hundreds of times per session.
• Build lower body strength and single leg balance, particularly calf, adductor and hip work, so the lunge to the wide ball is decelerated by muscle instead of by ligament.
• Replace indoor court shoes on a set schedule and keep the playing surface clean, since worn grip and dusty floors are behind a large share of ankle rolls.
• Match handle size and blade weight to your hand and grip style, and consciously loosen grip pressure between rallies, which is the single most effective step against wrist and elbow problems.
• Break the sustained forward crouch every twenty minutes with a few extensions and shoulder rolls, and use hip drive rather than pure trunk flexion in the ready position, to keep neck and lower back load down over long sessions.

When to Stop and Get Medical Help

Most of the injuries on this page are treated at home. These signs are not.

• A visible deformity, an obvious bend in a limb or finger, or the inability to put weight on a leg after a fall, which suggests a fracture or dislocation.
• Any blow to the head followed by confusion, memory gaps, repeated vomiting, worsening headache or loss of consciousness.
• Numbness, pins and needles or weakness in an arm or leg, which points at nerve involvement rather than a muscle problem.
• A joint that locks, will not move through its normal range, or gives way when you load it.
• A ball or paddle strike to the eye followed by blurred vision, blood inside the eye, an irregular pupil or pain on eye movement.
• A player who becomes confused, agitated or collapses in a hot hall, which is treated as heat stroke until proven otherwise.
