Design outcomes

Primary

Measure	Time frame
1st-12th training session: Back squats 10 RM with superimposed EMS on leg and trunk muscle groups; 4 exhaustive sets. Exhaustion is reached when load caannot be moved and is documented by RPE-scale (rate of perceived exertion).	—

Secondary

Measure	Time frame
Blood collection for hormone analysis of testosterone, cortisol, hGH, CK (ELISA-Kits), respiratory measurements (ZAN 680) and lactate analysis (Ebio plus) and request of perceived physical pain via visual analogue scale until 48 hours after exercise is conducted at 1st and 12th training session. Tests for performance parameter 1 week before, 1 week after and 3 weeks after training intervention: Strength diagnostics (mechatronic), Jumps (Optojump), Sprints (Sportronic), aerobic test (SRM, ZAN 680), anaerobic test (SRM).	—
