The study investigated the effects of different intrasession exercise sequences on the cardiorespiratory and neuromuscular adaptations induced by water-based concurrent training in young subjects. Twenty-six healthy young women (25.1 ± 2.9 years) were placed into 2 water-based concurrent training groups: resistance before (RA, n = 13) or after (AR, n = 13) aerobic training. Subjects trained resistance and aerobic training during 12 weeks, 2 times per week performing both exercise types in the same training session. Peak oxygen uptake (V[Combining Dot Above]O2peak), rate of force development (RFD) obtained during an isometric peak torque knee extension protocol, jump height, and neuromuscular economy (normalized electromyography at 80% of pretraining knee extension isometric peak torque) in young women were determined. After training, there was a significant increase (p < 0.001) in both RA and AR in the V[Combining Dot Above]O2peak, with no differences between groups (7 vs. 5%). The maximal isometric knee extension RFD showed significant increases (p = 0.003) after training (RA: 19 vs. AR: 30%), and both groups presented similar gains. In addition, the countermovement jump height also increased (p = 0.034) after training (RA: 5% vs. AR: 6%), with no difference between groups. After training, there were significant improvements on vastus lateralis (p < 0.001) (RA: -13% vs. AR: -20%) and rectus femoris (p = 0.025) (RA: -17% vs. AR: -7%) neuromuscular economy, with no difference between groups. In conclusion, 12 weeks of water-based concurrent training improved the peak oxygen uptake, RFD, jump height, and neuromuscular economy in young women independent from the intrasession exercise sequence.
该研究调查了不同的 session 内运动顺序对年轻受试者进行水上同步训练所引起的心肺和神经肌肉适应性的影响。26 名健康年轻女性（25.1±2.9 岁）被分为 2 个水上同步训练组：先进行阻力训练组（RA，n = 13）或先进行有氧训练组（AR，n = 13）。受试者在 12 周内进行阻力训练和有氧训练，每周 2 次，在同一训练 session 中同时进行这两种运动类型。测定了年轻女性的峰值摄氧量（V̇O2peak）、在等长峰值扭矩膝关节伸展方案中获得的力量发展速率（RFD）、跳跃高度和神经肌肉经济性（在训练前膝关节伸展等长峰值扭矩的 80%时的标准化肌电图）。训练后，RA 组和 AR 组的 V̇O2peak 均显著增加（p < 0.001），两组之间无差异（7%对 5%）。最大等长膝关节伸展 RFD 在训练后显著增加（p = 0.003）（RA 组：19%对 AR 组：30%），两组的增加幅度相似。此外，反向运动跳跃高度在训练后也增加了（p = 0.034）（RA 组：5%对 AR 组：6%），两组之间无差异。训练后，股外侧肌（p < 0.001）（RA 组：-13%对 AR 组：-20%）和股直肌（p = 0.025）（RA 组：-17%对 AR 组：-7%）的神经肌肉经济性有显著改善，两组之间无差异。总之，12 周的水上同步训练改善了年轻女性的峰值摄氧量、RFD、跳跃高度和神经肌肉经济性，且与 session 内运动顺序无关。
