To investigate changes in muscular force production before and after sport\u2010specific (repeated\u2010sprint) and non\u2010specific (knee extension\u2010flexion) fatiguing exercise, and explore the sensitivity and specificity of isokinetic endurance (ie, muscle\u2010specific) and single\u2010leg vertical jump (ie, whole limb) tests to identify previous hamstring injury. Twenty Western Australia State League footballers with previous unilateral hamstring injury and 20 players without participated.

Greater reductions in isokinetic knee flexor torque (\u221216%) and the concentric hamstring:quadriceps peak torque ratio (\u221215%) were observed after repeated\u2010sprint running only in the injured (kicking) leg and only in the previously injured subjects. Changes in (1) peak knee flexor torque after repeated\u2010sprint exercise, and (2) the decline in knee flexor torque during the isokinetic endurance test measured after repeated\u2010sprint exercise, correctly identified the injured legs (N\u00a0=\u00a020) within the cohort (N\u00a0=\u00a080) with 100% specificity and sensitivity. Decreases in peak knee flexor torque and the knee flexor torque during an isokinetic endurance test after repeated\u2010sprint exercise identified previous hamstring injury with 100% accuracy.
