Abstract

PURPOSE:

To demonstrate the potential for a simple clinical test of hamstring muscle strength to identify susceptibility to muscle strain injury.

METHODS:

A single-case design was used; specifically, an elite-level male Australian Rules football player performed bilateral isometric maximum voluntary contractions of the hamstring muscles on a weekly basis for a period of 5 weeks preceding a right hamstring muscle strain injury.

RESULTS:

Minimal asymmetry (no greater than ±1.2% difference) was evident in the hamstring isometric maximum voluntary contractions during the first 4 weeks, but 5 days prior to injury, the right hamstring isometric maximum voluntary contraction was reduced by 10.9% compared to the left.

CONCLUSION:

Measuring asymmetry in isometric maximum voluntary contractions of the hamstring muscles may be a useful clinical test to identify susceptibility to muscle strain injury.
