HRmax (beats·min^−1)	180 ± 11	181 ± 14	189 ± 7	188 ± 7
[La^−]b	9.12 ± 2.41	10.65 ± 1.69	8.04 ± 3.54	9.21 ± 2.01

Data are presented as mean ± SD. TG: training group; CG: control group; VO_2max: maximal oxygen uptake; 𝑉_𝐸: ventilation; RER: respiratory exchange ratio; HR_max: maximal heart rate; [La⁻]_b: lactate concentration in blood, ^∗∗𝑃<0.01, difference within group from pre- to posttest, ^#𝑃 < 0.05, differences in changes from pre- to posttest between groups.
