Mean isokinetic peak torques (percentage compared with contralateral leg) and players with a greater than 10% deficit without reinjury compared with players with reinjury within 2 months of RTS

For the mean peak torques, the percentage is of the uninjured leg, that is, a value lower than 100% reflects a lower torque than the uninjured leg. For the 10% deficit category, the number (percentage) shown is for those athletes displaying a deficit of >10% with their uninjured leg for the individual mode of testing.

H conc, hamstrings concentric, H ecc, hamstrings eccentric; Q conc, quadriceps concentric; RTS, return to sport.
