极低的负载（例如，<30%的重复最大值），可有效预防各种人群的肌肉骨骼损伤，并提高运动坚持性，尤其是老年人和慢性病患者。然而，使用这种类型的协议的长期干预是众所周知的，对肌肉大小和力量适应的影响很小。尽管有这样的知识，非常低强度的阻力运动（VLRE）与缓慢的运动和强直性力量的产生（ST）显着增加肌肉的大小和力量。为了进一步探索ST-VLRE在临床环境中的疗效，本研究检查了ST-VLRE对运动后抑制控制（IC）的影响。20名健康年轻男性（年龄：21 ± 0岁，身高：173.4 ± 1.2 cm，体重：67.4 ± 2.2 kg）在交叉设计中进行了ST-VLRE和正常VLRE。两种方案的上样量均设定为一次重复最大值的30%。两种方案均采用双侧膝关节伸展进行编程，每组重复10次。ST-VLRE和VLRE分别以缓慢（3秒同心，3秒偏心和1秒等长动作，每次重复之间没有休息）和正常收缩速度（1秒同心和1秒偏心动作，每次重复之间休息1秒）进行。在6个时间点使用色词Stroop任务评估IC：基线、运动前、运动后即刻和运动后30分钟恢复期内每10分钟。与每次运动前相比，ST-VLRE和VLRE后即刻的IC参数--反向Stroop干扰评分显著降低（与基线和/或运动前相比，两种方案的降低率分别> 32%和25%;所有P < 0.05）。ST-VLRE后IC的改善，但VLRE后没有，直到运动后20分钟恢复期仍显着（与基线和运动前相比下降率>48%;均P < 0.001）。ST-VLRE组运动后IC改善程度显著高于VLRE组（条件×时间相互作用效应P = 0.010）。提示ST-VLRE能有效改善运动后IC。因此，ST-VLRE可能是改善认知功能的有效抗阻运动方案。认知功能;脑健康;乳酸;肌电活动;唤醒
The extremely low loads (e.g., <30% of one-repetition maximum) involved in performing resistance exercise are effective in preventing musculoskeletal injury and enhancing exercise adherence in various populations, especially older individuals and patients with chronic diseases. Nevertheless, long-term intervention using this type of protocol is known to have little effects on muscle size and strength adaptations. Despite this knowledge, very low-intensity resistance exercise (VLRE) with slow movement and tonic force generation (ST) significantly increases muscle size and strength. To further explore efficacy of ST-VLRE in the clinical setting, this study examined the effect of ST-VLRE on post-exercise inhibitory control (IC). Twenty healthy, young males (age: 21 ± 0 years, body height: 173.4 ± 1.2 cm, body weight: 67.4 ± 2.2 kg) performed both ST-VLRE and normal VLRE in a crossover design. The load for both protocols was set at 30% of one-repetition maximum. Both protocols were programmed with bilateral knee extension for six sets with ten repetitions per set. The ST-VLRE and VLRE were performed with slow (3-sec concentric, 3-sec eccentric, and 1-sec isometric actions with no rest between each repetition) and normal contractile speeds (1-sec concentric and 1-sec eccentric actions and 1-sec rests between each repetition), respectively. IC was assessed using the color-word Stroop task at six time points: baseline, pre-exercise, immediate post-exercise, and every 10 min during the 30-min post-exercise recovery period. The reverse-Stroop interference score, a parameter of IC, significantly decreased immediately after both ST-VLRE and VLRE compared to that before each exercise (decreasing rate >32 and 25%, respectively, vs. baseline and/or pre-exercise for both protocols; all Ps < 0.05). The improved IC following ST-VLRE, but not following VLRE, remained significant until the 20-min post-exercise recovery period (decreasing rate >48% vs. baseline and pre-exercise; both Ps < 0.001). The degree of post-exercise IC improvements was significantly higher for ST-VLRE than for VLRE (P = 0.010 for condition × time interaction effect). These findings suggest that ST-VLRE can improve post-exercise IC effectively. Therefore, ST-VLRE may be an effective resistance exercise protocol for improving cognitive function.
