Abstract
This study investigated variations in one-repetition maximum (1RM) performance and electromyographic (EMG) responses of the hamstrings during knee flexion, with the ankle in dorsiflexion and plantarflexion, in order to recommend which position is best for training or testing for hamstring strength. Twelve female collegiate basketball players performed separate 1RM and 6-repetition submaximum (6-rep submax) leg curl tests at the two ankle positions. Analyses for 1RM test performance revealed that 1RM performance was significantly improved in dorsiflexion, and additional analyses for the 1RM test indicated significantly higher rmsEMG in dorsiflexion, with no significant position by muscle interaction in the hamstrings. Analyses for the 6-rep submax test indicated no significant rmsEMG differences across positions; pairwise comparisons revealed a significant position by muscle interaction accounted for by differences in the biceps femoris (BF) and tibialis anterior with BF rmsEMG significantly higher in plantarflexion. These data suggest that using plantarflexion during a hamstring curl may be best to maximally isolate the hamstrings muscle and eliminate any gastrocnemius involvement as a secondary knee flexor.
