Tests are listed in order of presentation. Rest intervals between strength trials were 60 s. Breaks are reported as minimal rest times after each test (min). 1-RM, one-repetition maximum; CV, coefficient of variation; EMG, electromyogram; KE, knee extensors; MVC, maximal voluntary contraction; MG, medial gastrocnemius; RPE, rating of perceived exertion; SD, standard deviation; TA, tibialis anterior
