本研究旨在研究从最大无氧功率（MAnP）到接近最大摄氧量（[公式：见正文]）的逐渐降低强度训练（降低强度训练）对未接受训练的年轻男性的MAnP、最大累积氧亏（MAOD）和[公式：见正文]的影响。17名未经训练的年轻人被随机分为训练组（TR; n = 9）或对照组（CON; n = 8）。TR组进行低强度训练，而CON组不进行任何运动。在整个训练期间，每次训练的平均训练时间为275 ± 135 s。[公式：见正文]、MAOD和MAnP的绝对值和相对值（p < 0.01）均存在组×时间相互作用。TR组在8周的训练计划后，所有变量的值均显著增加，TR组所有变量的相对值均显著高于CON组。仅TR组的大腿前部和后部肌肉厚度以及最大等速膝关节伸展和屈曲强度有所改善（p < 0.05）。尽管每次训练的时间很短，但从对应于MAnP的强度逐渐降低到大约100%的强度的单次运动训练可以同时改善MAnP、MAOD和[公式：见正文]。
This study aimed to investigate the effects of a gradually decreasing intensity training from that corresponding to maximal anaerobic power (MAnP) to that of near maximal oxygen uptake ([Formula: see text]) (decrescent intensity training) on MAnP, maximal accumulated oxygen deficit (MAOD), and [Formula: see text] in untrained young men. Seventeen untrained young men were randomly divided into either a training (TR; n = 9) group or a control (CON; n = 8) group. The TR group performed the decrescent intensity training, whereas the CON group did not perform any exercises. The mean training time per session throughout the training period was 275 ± 135 s. There was a Group × Time interaction for both absolute and relative (p < 0.01) values of [Formula: see text], MAOD, and MAnP. The TR group had significantly increased values for all variables after the 8-week training program, and the relative values of all variables were significantly higher in the TR group than in the CON group. Muscle thicknesses in the anterior and posterior aspects of the thigh and maximal isokinetic knee extension and flexion strengths improved only in the TR group (p < 0.05). A single-exercise training with gradually decreasing intensity from that corresponding to the MAnP to that of approximately 100% [Formula: see text] improves MAnP, MAOD, and [Formula: see text] concurrently, despite the short training time per session.
