Values are means ±s.e.m. of 7 observations in each group. Eccentric thigh, the thigh which performed the eccentric exercise 2 days before the two-legged concentric exercise; Control thigh, the contralateral thigh that acted as unexercised control thigh.

^*Significantly different from contralateral control (P < 0.05).

^†Significantly different from the ipsilateral 10 min value on the same exercise step (P < 0.05).
