Hamstring injury prevention: Nordic curls and eccentric dosing
The Nordic hamstring exercise has some of the strongest prevention evidence in sports medicine and some of the worst uptake. That mismatch comes down mostly to dose.
Condition
Grading, rehab timelines, and return-to-play after hamstring strain.
ICD-10-CM: S76.3
A hamstring strain is a tear or pull of the muscles at the back of the thigh, most often during sprinting or sudden acceleration. It usually causes a sharp pain and can range from a minor tweak to a more significant injury, and re-injury is common if you return to sport too soon.
Physiotherapy guides recovery through graded exercise and clear return-to-play criteria that rebuild strength and speed safely. In this guide we cover grading, rehabilitation timelines, and return-to-sport decisions for hamstring strains, practical guidance for clinicians and straightforward advice so athletes and patients recover fully and reduce the chance of it happening again.

The British Athletics Muscle Injury Classification (BAMIC) was built to fix that by describing both how extensive an injury is and where in the muscle it sits.
Sprinters and jumpers tear hamstrings, distance runners strain calves, and the rectus femoris sits between them in the acceleration and take-off events. Knowing the athlete's event tells you where to look before they describe a single symptom.
Football demands sustained high-speed running and repeated deceleration under fatigue, so clearance should rest on limb symmetry in hop and strength testing, completion of the sport-specific task itself, and the player's confidence in the injured limb.
