Tennis Injuries: Serving Without Pain

Is your serve getting weaker instead of stronger? Does a burning pain on the outside of your elbow flare up every time you hit a backhand? These are warning signs that your technique or equipment is quietly damaging your tendons – and playing through the pain only makes things worse.

Tennis in Malaysia: Heat, Hard Courts, and Injury Risk

Tennis enjoys a strong following in Malaysia, bolstered by the success of Malaysian players on the international stage and the accessibility of public and private courts across the country. From the National Tennis Centre in Kuala Lumpur to community courts in Penang, Kota Kinabalu, and Johor Bahru, Malaysians of all ages play regularly.

Most Malaysian courts are hard courts – a surface that generates higher impact forces than clay – and the tropical climate adds heat stress that accelerates fatigue and increases injury vulnerability. Understanding the common injuries associated with tennis, particularly those related to the serve, can help players stay on court and perform at their best.

Tennis Elbow: More Than Just an Elbow Problem

Tennis elbow, or lateral epicondylitis, is the most well-known tennis injury. It affects the common extensor tendon on the outer side of the elbow, causing pain with gripping, lifting, and particularly backhand strokes. Despite its name, tennis elbow is a degenerative tendinopathy rather than an inflammatory condition – the tendon fibres undergo structural breakdown from repeated microtrauma, and the body's repair process fails to keep pace with the damage.

Several factors contribute to tennis elbow in Malaysian players. Racket grip size is critically important – a grip that is too small forces the forearm extensors to work harder to maintain control, while a grip that is too large prevents a secure hold.

String tension also plays a role: higher string tension increases the vibration transmitted through the racket to the arm, while lower tension provides a softer response and reduces impact forces. Players using stiff rackets with thin beams are at greater risk than those using more flexible, dampened frames.

From a technique perspective, leading the backhand with the wrist rather than the shoulder and trunk, late contact points, and a stiff hitting arm all increase the load on the lateral elbow. A physiotherapist working alongside a tennis coach can identify and correct these biomechanical faults, addressing both the symptom and the cause simultaneously.

Rotator Cuff Strain from Serving

The tennis serve is the most physically demanding stroke in the sport. It requires the shoulder to move through extreme ranges of external rotation (the cocking phase), followed by rapid internal rotation and arm acceleration (the acceleration phase), and then controlled deceleration (the follow-through). The rotator cuff muscles – supraspinatus, infraspinatus, teres minor, and subscapularis – must work intensively during all three phases.

Rotator cuff tendinopathy and partial tears typically develop when the shoulder lacks sufficient external rotation mobility, the scapular stabilisers (serratus anterior, lower trapezius) are weak, or the player relies on arm strength rather than the kinetic chain to generate power. The kinetic chain principle states that serve power should originate from the legs, transfer through the trunk, and be delivered by the arm – if the legs or trunk are weak, the shoulder compensates and becomes overloaded.

Rehabilitation of rotator cuff injuries involves progressive strengthening of the rotator cuff and scapular muscles, restoration of shoulder mobility, and gradual reintroduction of the serve beginning with shadow swings, progressing to gentle flat serves, and eventually returning to full-speed serves with spin. This process typically takes six to twelve weeks depending on severity.

Wrist Injuries and Lower Back Pain

Wrist injuries in tennis often result from topspin-heavy forehands and kick serves, which require extreme wrist flexion and ulnar deviation. Extensor carpi ulnaris (ECU) tendinopathy and TFCC (triangular fibrocartilage complex) injuries cause pain on the ulnar (pinky) side of the wrist and can be debilitating for players who rely on spin. Rest, wrist bracing, and progressive loading exercises form the mainstay of treatment.

Lower back pain in tennis players is frequently linked to the serve motion. The combination of hyperextension during the trophy position, lateral flexion, and rapid rotation generates significant spinal loading.

Players who serve with an open stance and insufficient leg drive compensate with excessive lumbar extension, predisposing them to stress fractures of the pars interarticularis (spondylolysis) in severe cases. Core stability exercises, improved leg drive in the serve, and thoracic mobility work are essential preventive strategies.

Ankle Sprains on Hard Courts

The rapid lateral movements, sudden stops, and direction changes inherent in tennis place the ankle at risk. Hard courts provide less give than clay, and worn-out shoes with degraded lateral support increase sprain risk.

An ankle sprain on court typically involves the anterior talofibular ligament (ATFL) and can range from a mild stretch to a complete rupture. Players should replace tennis shoes every 45 to 60 hours of play and ensure they choose shoes designed for tennis – running shoes lack the lateral reinforcement needed for court movement.

Shockwave Therapy for Persistent Tendon Pain

For tennis elbow and rotator cuff tendinopathy that do not respond to conventional physiotherapy within eight to twelve weeks, extracorporeal shockwave therapy (ESWT) offers an evidence-based treatment option. Shockwave therapy delivers acoustic energy pulses to the affected tendon, stimulating blood flow, promoting cellular repair, and breaking down calcific deposits.

Clinical studies report success rates of 60 to 80 percent for chronic lateral epicondylitis, often allowing patients to avoid corticosteroid injections or surgery. Sessions are typically performed once weekly for three to five weeks. Several physiotherapy clinics across Malaysia now offer this modality, making it increasingly accessible for recreational and competitive tennis players.

Staying on Court in Malaysian Conditions

Playing tennis in Malaysia's heat requires specific precautions. Scheduling matches for early morning or evening avoids peak sun exposure. Hydration with electrolyte-enhanced fluids is essential – by the time you feel thirsty, you are already mildly dehydrated, and dehydrated muscles cramp more readily.

Wearing lightweight, moisture-wicking clothing and applying broad-spectrum sunscreen protects against heat-related illness and UV damage. Taking full advantage of changeover breaks to sit, hydrate, and towel off helps maintain performance and reduces injury risk throughout a match.
