ABPMR Sports Medicine key terms

Damage to the anterior cruciate ligament, often from noncontact deceleration or pivot; causes knee instability, hemarthrosis, and a positive Lachman test.

Injury to the knee's fibrocartilaginous shock absorbers, producing joint-line pain, swelling, and mechanical symptoms; diagnosis is clinical and confirmed by MRI.

Anterior knee pain worsened by squatting, stairs, or prolonged sitting, without structural damage; managed with load modification, hip and quadriceps strengthening, and gradual return.

Abnormal contact between the femoral head-neck junction and acetabular rim during hip motion, causing groin pain and labral or chondral damage; treated with activity change, therapy, or surgery.

Pain and dysfunction of the shoulder's cuff tendons from overload rather than acute tear; lateral shoulder pain with overhead activity and positive impingement provocation tests are typical.

Pain at the lateral elbow common extensor origin, worsened by gripping and wrist extension; a degenerative tendinopathy managed with load progression, bracing, and strengthening.

A spectrum from stress reaction to frank fracture caused by repetitive loading that exceeds bone remodeling; focal pain, tenderness, and imaging findings guide rest and return decisions.

Diffuse posteromedial shin pain from repetitive tibial loading, distinct from focal bone stress injury; managed by load reduction, footwear and biomechanical review, and graded return.

A stress fracture of the pars interarticularis, often in adolescent extension athletes; presents with focal low back pain and is confirmed by oblique radiographs or advanced imaging.

Overuse-induced pain and thickening of the Achilles tendon, typically midportion, with morning stiffness and load-related pain; eccentric or heavy-slow resistance exercise is first-line.

A focal subchondral bone lesion with possible cartilage separation, usually in skeletally immature knees; symptoms include activity-related pain, swelling, and mechanical catching.

Acute stretching or tearing of muscle fibers, commonly at the myotendinous junction during sprinting or explosive contraction; graded rehabilitation balances protection with early controlled loading.

Stretching or tearing of a ligament from a sudden force, graded by severity; pain, swelling, instability, and stress testing guide treatment and return to sport.

A traumatic brain injury from biomechanical forces, producing transient neurologic symptoms without routine structural imaging abnormalities; diagnosis is clinical and return requires gradual stepwise exertion.

A syndrome of impaired physiologic function from insufficient energy intake relative to exercise expenditure; affects bone, menstrual, endocrine, metabolic, and immune health in male and female athletes.

An inherited cardiac muscle disorder causing ventricular hypertrophy and diastolic dysfunction; a leading cause of sudden cardiac death in young athletes and often detected by screening ECG.

Airway narrowing during or after vigorous exercise in susceptible athletes, causing cough, wheeze, chest tightness, or reduced performance; diagnosis uses objective pulmonary testing.

Low hemoglobin from insufficient iron, common in endurance athletes; causes fatigue and impaired performance and requires dietary, absorption, and blood-loss evaluation.

Epstein-Barr virus infection causing fever, sore throat, fatigue, lymphadenopathy, and risk of splenic enlargement; athletes need activity restriction until splenic risk resolves.

Inherited hemoglobin variant that is usually asymptomatic but raises risk of exertional sickling, rhabdomyolysis, and collapse under heat, dehydration, or extreme exertion.

Interrelated low energy availability, menstrual dysfunction, and low bone mineral density in female athletes; can impair performance and increase stress fracture and long-term health risks.

The maximum rate of oxygen uptake during incremental exercise, reflecting cardiorespiratory fitness; expressed as milliliters per kilogram per minute and used to prescribe and monitor aerobic training.

The exercise intensity at which blood lactate rises faster than it can be cleared, marking a transition toward anaerobic contribution; useful for setting endurance training zones and predicting performance.

A multiple of resting metabolic rate used to quantify exercise intensity; one MET approximates oxygen consumption at rest and allows comparison across activities and exercise prescriptions.

A subjective scale of effort during exercise, commonly 6 to 20 or 0 to 10; useful when heart rate is unreliable and for adjusting intensity in rehabilitation or prescription.

A structured plan specifying frequency, intensity, time, and type of exercise, tailored to goals and limitations; progression and monitoring improve adherence and safety.

A supervised graded exercise test used to assess fitness, provoke exercise-related symptoms, or evaluate cardiac and pulmonary limitations; interpretation includes heart rate, blood pressure, ECG, and workload.

A structured history and examination before sports participation to identify conditions that may increase injury or sudden death risk; it supports safe participation decisions rather than serving as clearance alone.

A staged, criterion-based progression from injury or illness back to full sport, requiring symptom control, restored function, and graded exposure before unrestricted participation.

A structured warm-up or training regimen emphasizing balance, plyometrics, strength, and movement control; reduces ACL and lower-extremity injury risk in athletes.

A life-threatening emergency with core temperature above 40°C and central nervous system dysfunction during exertion; immediate cooling and emergency transport are essential.

A portable device that analyzes cardiac rhythm and delivers a shock for ventricular fibrillation or pulseless ventricular tachycardia; early use improves survival in sudden cardiac arrest.

A written, rehearsed protocol for sideline emergencies, specifying roles, equipment, communication, transport, and evacuation routes; it improves response time and coordination.

Point-of-care sonography used on the field or in clinic to assess muscle, tendon, ligament, joint, and nerve injury and to guide injections or aspiration in real time.

Delivery of medication into a target joint, tendon sheath, or bursa using real-time imaging guidance to improve accuracy and confirm needle placement.

Needle drainage of joint fluid for diagnosis or relief; in athletes it can evaluate hemarthrosis, infection, or crystal disease and is often ultrasound-assisted.

An older adult who trains and competes in sport; physiologic changes, chronic disease, medications, and slower recovery require tailored exercise prescription and injury prevention.

Injury to the physis in a skeletally immature athlete, which can affect growth; mechanism and focal tenderness guide imaging and activity restriction.

A contagious dermatophyte infection of glabrous skin causing annular scaly plaques; athletes in contact sports need treatment and rules-based clearance to prevent spread.

Exercise during pregnancy is generally safe with individualized modification; clinicians monitor maternal and fetal health and adjust intensity, hydration, and contact risk.
