  1. Data are means ± SD; *between-group differences as estimated by ANOVA; post-hoc Scheffè test at P < 0.05: significantly different from untrained subjects. – significantly different from endurance-trained athletes. #Significantly different from speed-power-trained athletes. Legend: BMI ‒ body mass index, HRmax ‒ maximal heart rate, \(\dot{V}\)O2max. maximal oxygen uptake; Hb ‒ haemoglobin, LA ‒ plasma lactate concentration, rest ‒ resting value, post ‒ post-exercise value, post-rest ‒ the difference between post-exercise and resting value.
