Bottom Line: Peak oxygen consumption ([Formula: see text]O2peak) and oxygen consumption at sub-maximal power outputs ([Formula: see text]O2submax) of 50 to 175 Watts in men and 50 to 125 Watts in women were assessed during an incremental cycling test both before and after 24 weeks of training.Increases in [Formula: see text]O2peak in both men and women were statistically larger in AD (18±9% and 25±11%) compared to ES (7±9% and 12±12%, p = 0.002 and 0.009, respectively) and SE (7±9% and 10±8%, p = 0.005 and 0.008, respectively).No statistical group interaction was observed for [Formula: see text]O2submax in men, but in women [Formula: see text]O2submax was statistically lower at week 24 in ES compared to AD at 75 W (-2±6% vs. +3±6%, p = 0.027) and 125 W (-4±5% vs. +2±5%, p = 0.010).

ABSTRACT
This study investigated the effects of endurance followed by strength training (ES, men n = 16; women n = 15), the reverse exercise order (SE, men n = 18, women n = 13) and concurrent endurance and strength training performed on alternating days (AD, men n = 21, women n = 18) on cardiorespiratory parameters. Peak oxygen consumption ([Formula: see text]O2peak) and oxygen consumption at sub-maximal power outputs ([Formula: see text]O2submax) of 50 to 175 Watts in men and 50 to 125 Watts in women were assessed during an incremental cycling test both before and after 24 weeks of training. Increases in [Formula: see text]O2peak in both men and women were statistically larger in AD (18±9% and 25±11%) compared to ES (7±9% and 12±12%, p = 0.002 and 0.009, respectively) and SE (7±9% and 10±8%, p = 0.005 and 0.008, respectively). No statistical group interaction was observed for [Formula: see text]O2submax in men, but in women [Formula: see text]O2submax was statistically lower at week 24 in ES compared to AD at 75 W (-2±6% vs. +3±6%, p = 0.027) and 125 W (-4±5% vs. +2±5%, p = 0.010). These findings indicate that endurance and strength training performed on alternating days may optimize the adaptations in [Formula: see text]O2peak in both sexes, while performing ES training in women may optimize cardiorespiratory fitness at sub-maximal power outputs.

Mentions: Absolute values of sub-maximal oxygen consumption are presented in Table 3. Statistical reductions in sub-maximal oxygen consumption scaled to body mass to the power of 0.75 (Fig 1) at week 24 were only found in men at 150 and 175 W (-6±5%, p = 0.002 and -4±4%, p = 0.010, respectively) but not women. No statistical group interaction was observed for sub-maximal oxygen consumption in men. However, in women statistical between-group differences at week 24 were observed between ES and AD (75W -2±6% vs. +3±6%, p = 0.027; 125 W -4±5% vs. +2±5%, p = 0.010).
