Statistically significant differences in maximal oxygen uptake between the given genotypes was marked by underlining: a – at p ≤ 0.05, A – at p ≤ 0.01.

Sp-St - speed and strength disciplines (disciplines with predominant anaerobic exercise metabolism); E-Sp-S - endurance-speed-strength disciplines (disciplines requiring both anaerobic and aerobic energy resources); E - endurance disciplines (disciplines with predominant aerobic exercise metabolism)
