 Maximum dynamic strength of the knee extensor and flexor muscles during pill withdrawal and consumption

Muscle functionDay 5 withdrawalDay 7 consumptionDay 14 consumption
Data are shown as means (SD), n = 14. MVIF, maximum voluntary isometric force; FDI, first dorsal interosseus muscle; ext, knee extension; flex, knee flexion. There were no significant differences between pill consumption and withdrawal for any of the variables.
