Fluid intake should reflect sweat loss, temperature, exercise duration, and individual tolerance. After long sessions, body-weight change can help estimate replacement needs. Avoid forcing large amounts of fluid over a short period, and consider electrolytes during prolonged exercise with heavy sweating. Headache, nausea, confusion, or severe weakness requires immediate assessment.
Supplements such as protein or creatine may help selected people when used appropriately, but they cannot replace a balanced diet, sound training, and sleep. Products may contain inaccurate doses, contaminants, or banned substances. Competitive athletes should choose independently tested products and consult a doctor or sports dietitian first.
Persistent fatigue, reduced performance, sleep or mood changes, an unusual resting heart rate, and recurrent illness can occur when training load and recovery are out of balance. Anaemia, infection, thyroid disease, and low energy availability should also be excluded. Management centres on reducing load, improving sleep and nutrition, and returning gradually.
RED-S develops when long-term energy intake does not adequately support training and essential body functions. It can affect menstrual function, bone health, hormones, immunity, mood, and performance. Recurrent stress fractures, unusual weight change, persistent fatigue, or menstrual disturbance warrant coordinated assessment by sports medicine, nutrition, and other relevant specialists.
Yes. Rhabdomyolysis may cause marked muscle pain, swelling, weakness, and tea-coloured urine, and severe cases can lead to acute kidney injury. Stop exercising and seek prompt testing of creatine kinase, kidney function, and electrolytes. Do not try to manage significant symptoms by simply drinking large amounts of water.
A very high body temperature with confusion, unusual behaviour, poor coordination, seizures, or loss of consciousness should raise strong concern for exertional heat stroke. Start emergency care and rapid whole-body cooling immediately and call emergency services. Continue cooling while transport is arranged.
Yes. Symptoms often develop during or soon after exercise and may worsen with cold air, pollen, or high-intensity training. Diagnosis usually involves lung-function testing or an exercise challenge. A structured warm-up, environmental measures, and medication prescribed by a clinician can help control symptoms.
Yes. Stop exercising and seek medical assessment, especially after fainting during exertion, chest pain with breathing difficulty, or a family history of sudden death at a young age. These symptoms may relate to an abnormal heart rhythm, heart muscle disease, or another cardiopulmonary condition; avoid intense exercise until the cause is clarified.
No. Concussion is diagnosed mainly from the injury history, symptoms, and neurological assessment, and routine CT or MRI scans may be normal. Imaging is primarily used to look for serious structural injuries such as bleeding inside the skull or a fracture.
No. Anyone with a suspected concussion should be removed from sport immediately, assessed by a qualified professional, and guided through a staged return to learning, daily activity, and sport. Worsening headache, repeated vomiting, altered consciousness, seizures, or limb weakness requires emergency care.
Delayed-onset muscle soreness usually begins several hours to a day after exercise, affects a broader area, and gradually improves. A strain often causes sudden local pain during activity and may include weakness, swelling, or bruising.
Shin splints usually cause pain along a broader area of the tibia. A stress fracture more often causes focal bony tenderness and may hurt during walking or at rest. Persistent symptoms need professional assessment.
Do not continue running through the pain. Early bone stress injury may not be visible on X-ray, and a clinician may arrange MRI based on the symptoms and examination.
Achilles tendinopathy usually causes gradually developing pain and stiffness. A rupture is often sudden during push-off or jumping, with a pop, weakness, or inability to rise onto one set of toes. Examination and sometimes imaging confirm the diagnosis.
A high ankle sprain injures the ligaments between the tibia and fibula, with pain usually located above a typical lateral ankle sprain. Recovery may take longer, and ankle stability should be assessed.
Painless snapping often occurs when a tendon moves over a bony structure and usually needs no treatment. Pain, catching, or restricted motion warrants assessment of the labrum, tendons, and hip joint.
Heel pain during growth can result from repeated traction at the calcaneal growth plate. Running and jumping should be reduced and the child assessed if pain causes a limp or affects daily activity.
Osgood-Schlatter disease is a possible cause and is common during rapid growth in adolescents who do frequent running and jumping. It is usually managed by adjusting activity and improving flexibility and strength.
Golfer’s elbow mainly causes pain on the inside of the elbow, while tennis elbow mainly affects the outside. Both are commonly associated with repeated use of the forearm tendons, but rehabilitation targets differ.
Yes. Tennis elbow is associated with repeated loading of the forearm extensor tendons. Lifting, tool use, typing, and racquet sports can all provoke pain on the outside of the elbow.
Clicking without pain or weakness can often be observed. When it follows an injury or occurs with pain, instability, or loss of strength, examination should come first and can guide whether MRI or ultrasound is needed.
It may indicate a biceps tendon rupture, often with sudden pain, bruising, or a change in strength. Some patients do not require surgery, but the location of the tear and functional needs should be assessed promptly.
Yes. Long-head biceps tendon disorders commonly cause pain at the front of the shoulder, especially with overhead movement, lifting, or reaching behind the body.
Repeated overhead activity can irritate the rotator cuff tendons and subacromial bursa. Early care may include adjusting training load and working on rotator cuff and shoulder-blade control. Persistent pain should be assessed.
Patellar tendinopathy commonly causes localised pain below the kneecap that worsens with jumping, running, or squatting. Treatment usually focuses on load management and progressive strengthening.
Repeated swelling can indicate inflammation or structural damage inside the joint, including a meniscus, cartilage, or ligament problem. Reduce the provoking activity and arrange a clinical assessment.
Symptoms may include pain behind the knee, swelling, or instability when walking downstairs. Mild isolated injuries can often be managed non-operatively, while marked or multi-ligament instability needs further assessment.
Most isolated MCL injuries recover with bracing and rehabilitation. Surgery may be assessed for severe laxity, an avulsion injury, or damage involving other knee ligaments.
Clicking without pain, swelling, or locking often needs no specific treatment. Clicking with pain, restricted motion, or a history of injury warrants assessment of the meniscus, cartilage, and patellofemoral joint.
Common causes include patellofemoral pain, patellar tendon disorders, and cartilage injury. Assessment considers the pain location, patellar tracking, lower-limb strength, and movement pattern.
