Individual limb work for the (a) right and (b) left leg as the leading leg, during single support and as the trailing leg. For the right leg, we compared the −25, 0/−25 and +25/−25% conditions, whereas for the left leg, we compared the +25%, +25/0% and +25%/−25% conditions because stance duration was nearly constant across these conditions. With increasing asymmetry, subjects performed more negative work with their right leg during single support, and with their left leg as the leading leg. Subjects performed more positive work during single support on the left leg. Asterisks (*) significantly different from symmetric and dagger symbols (†) significantly different from moderately asymmetric. Significance at p < 0.05. Error bars are ± 1 s.e. black bars, highly asymmetric; dark grey bars, moderately asymmetric; light grey bars, symmetric.
