Values are means ± SD; %∆, within group changes from pre- to post-training; ES, effect size. V̇O2max, maximum oxygen uptake; V̇O2/HR, O2 pulse; VT1, first ventilatory threshold; VT2, second ventilatory threshold. N = 10 for each group.
* Significantly greater than pre-training value (P < 0.05);
‡ Significantly greater changes than the CON (P < 0.05);
§ Significantly greater changes than the SSG (P < 0.05).
