The aim of the present study was to compare the effects of using different intensities and types of aerobic exercise (i. e., cycle ergometer or running) during concurrent training on neuromuscular adaptations. A total of 44 young women were randomly assigned to 1 of 4 groups: concurrent strength and continuous running training (SCR, n=10), concurrent strength and interval running training (SIR, n=11), concurrent strength and continuous cycle ergometer training (SCE, n=11), or strength training only (STO, n=12). Each group trained twice a week during 11 weeks. The following strength measurements were made on all subjects before and after training period: maximal strength (1RM) in knee extension, bench press and leg press exercises; local muscular endurance (number of repetitions at 70% of 1 RM) in knee extension and bench press exercises; and isometric and isokinetic peak torque of knee extension. There were significant increases in the upper and lower-body 1 RM, isometric and isokinetic peak torque in all training groups (p<0.001), with no differences between groups. The present results suggest that in young women, concurrent training performed twice a week promotes similar neuromuscular adaptations to strength training alone, regardless of the type and the intensity in which the aerobic training is performed.
本研究旨在比较在同期训练中使用不同强度和类型的有氧运动（即，固定自行车或跑步）对神经肌肉适应性的影响。共有 44 名年轻女性被随机分配到以下 4 组中的 1 组：力量和连续跑步训练（SCR，n=10）、力量和间歇跑步训练（SIR，n=11）、力量和连续固定自行车训练（SCE，n=11）或仅进行力量训练（STO，n=12）。每组在 11 周内每周训练两次。在训练前后，对所有受试者进行了以下力量测量：膝关节伸展、卧推和腿推运动的最大力量（1RM）；膝关节伸展和卧推运动的局部肌肉耐力（1RM 的 70%重复次数）；以及膝关节伸展的等长和等速峰值扭矩。所有训练组的上下肢 1RM、等长和等速峰值扭矩均显著增加（p<0.001），组间无差异。本研究结果表明，在年轻女性中，每周进行两次的同期训练可促进与单独进行力量训练相似的神经肌肉适应性，无论有氧运动的类型和强度如何。
