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.
本研究调查了先进行耐力训练再进行力量训练（ES组，男性n = 16；女性n = 15）、相反的训练顺序（SE组，男性n = 18，女性n = 13）以及隔天进行耐力和力量训练（AD组，男性n = 21，女性n = 18）对心肺参数的影响。在24周训练前后的递增自行车测试中，评估了男性50至175瓦、女性50至125瓦次最大功率输出时的峰值耗氧量（[公式：见正文]O2peak）和耗氧量（[公式：见正文]O2submax）。与ES组（男性7±9%，女性12±12%，p分别为0.002和0.009）和SE组（男性7±9%，女性10±8%，p分别为0.005和0.008）相比，AD组男性和女性的[公式：见正文]O2peak增加在统计学上更大（分别为18±9%和25±11%）。男性的[公式：见正文]O2submax未观察到统计学上的组间交互作用，但在女性中，与AD组相比，ES组在第24周时75瓦（-2±6%对+3±6%，p = 0.027）和125瓦（-4±5%对+2±5%，p = 0.010）时的[公式：见正文]O2submax在统计学上更低。这些发现表明，隔天进行耐力和力量训练可能会优化两性的[公式：见正文]O2peak适应性，而女性进行ES训练可能会优化次最大功率输出时的心肺适能。
