EMG activity of selected lower-limb muscles measured during repeat-sprint ability test, normalized by the first sprint values observed in control condition (n = 10). a = main time effect, significant difference from 1st sprint; b = main time effect, significant difference from 2nd sprint; ¥ = main condition effect, significant difference from control condition; * = interaction effect, significant difference from 1st sprint in drop jump condition; # = interaction effect, significant difference from 2nd sprint in drop jump condition § = interaction effect, significant difference from 1st sprint in heavy sled condition; φ = interaction effect, significant difference from 2nd sprint in heavy sled condition
