Handgrip strength of the right hand was measured with a hydraulic, analogue handheld dynamometer (JAMARLeg muscle strength was measured in kilograms with an EN-Dynamic seated leg press (Enraf-Nonius, Rotterdam, The Netherlands). After adjusting the seat and a warm-up, participants had to perform one leg press per fixed step. The weight was increased gradually in seven fixed steps dependent on their body weight to directly determine the 1 repetition maximum (1 RM). There were only 7 attempts to determine the 1 RM to prevent injury and overexerting participants.
