MV: mean value. SD: standard deviation. MIN: minimum. MAX: maximum. BMI: body mass index. rel. VO_2peak: maximal O₂ uptake relative to body weight (BW). IAT: individual anaerobic threshold. 𝐹_max: maximal isometric power during plantar flexion. 𝐹_iso: maximal isokinetic power during plantar flexion at 500°/s.
