Your athlete pulled the hamstring again. Stretching will not stop it.
A hamstring strains because it was weak in the stretched position a sprint demands, not because it felt tight. Stretching changes how the muscle feels for an hour. It does not change what the muscle holds under load.
- The strain happens at full speed, in the position the muscle could not hold
- A stretch never built strength in that position
- Loading the muscle where it tore is what breaks the cycle
We test strength in the lengthened position on both legs and build the injured side back to a real standard before your athlete sprints again.
A second and third strain in one season is a pattern, not bad luck.
