This study examined the effects of concurrent strength and endurance training on neuromuscular and endurance characteristics compared to strength or endurance training alone. Previously untrained men were divided into strength (S: n=16), endurance (E: n=11) or concurrent strength and endurance (SE: n=11) training groups. S and E trained 2 times and SE 2 + 2 times a week for strength and endurance during the 21-week period. Maximal unilateral isometric and bilateral concentric forces of leg muscles increased similarly in S and SE by 20-28% (p<0.01) and improvements in isometric forces were accompanied by increases (p<0.05) of maximal muscle activation. Rate of force development of isometric action (p<0.05) improved only in S. The increase in muscle cross-sectional area of the quadriceps femoris in SE (11%, p<0.001) were greater than in S (6%, p<0.001) or in E (2%, p<0.05). SE and E increased maximal cycling power (SE: 17% and E: 11%, p<0.001) and VO(2MAX) (SE: 17%, p<0.001 and E: 5%, ns.). These results suggest that the present moderate volume 21-week concurrent SE training in previously untrained men optimizes the magnitude of muscle hypertrophy, maximal strength and endurance development, but interferes explosive strength development, compared with strength or endurance training alone.
本研究比较了力量和耐力训练与同时进行的力量和耐力训练对神经肌肉和耐力特征的影响。先前未经训练的男性被分为力量训练组（S：n=16）、耐力训练组（E：n=11）或同时进行的力量和耐力训练组（SE：n=11）。S 和 E 在 21 周的时间里每周进行 2 次和 2+2 次的力量和耐力训练，SE 训练组的力量和耐力训练与 S 和 E 组相同。S 和 SE 组的单侧等长和双侧向心腿部肌肉最大力量分别增加了 20-28%（p<0.01），等长力量的提高伴随着最大肌肉激活的增加（p<0.05）。等速动作的力发展速度（p<0.05）仅在 S 组中得到改善。SE 组股四头肌横截面积增加（11%，p<0.001）大于 S 组（6%，p<0.001）或 E 组（2%，p<0.05）。SE 和 E 组增加了最大自行车功率（SE：17%和 E：11%，p<0.001）和 VO(2MAX)（SE：17%，p<0.001 和 E：5%，ns.）。这些结果表明，与单独进行力量或耐力训练相比，目前在未经训练的男性中进行的 21 周中等强度的同时进行的 SE 训练可以优化肌肉肥大、最大力量和耐力发展的幅度，但会干扰爆发力的发展。
