概括

气动阻力训练 (PRT) 和传统阻力训练 (TRT) 均改善了瘦身量. PRT独特地降低了身体脂肪百分比,这表明它可能会提供优越的身体成分益处和代谢健康改善.

科学领域:

运动生理学运动生理学
代谢学代谢学代谢学
身体组成分析身体成分分析

背景情况:

气动阻力训练 (PRT) 提供了比传统阻力训练 (TRT) 更长的压力时间,可能产生更大的适应性.
代谢健康与人体组成和血清代谢物概况密切相关.
了解PRT和TRT对这些参数的比较影响对于优化培训干预至关重要.

研究的目的:

为了比较PRT和TRT对肌肉力量,身体组成和血清代谢的作用.
调查PRT和TRT之间代谢标记和身体组成变化的潜在差异.

主要方法:

69名男性被随机分配到10周的PRT,TRT或对照组.
使用生物阻抗分析评估身体成分 (脂肪质量,瘦肉质量).
在干预前后使用高通量核磁共振光谱测量血清代谢物度.

主要成果:

无论是PRT还是TRT都显著增加了瘦肉量.
与TRT不同,PRT导致身体脂肪百分比的统计显著减少.
在PRT和TRT组中都观察到小高密度脂蛋白 (S-HDL-L) 和小高密度脂蛋白颗粒 (S-HDL-P) 的增加,但当控制身体组成变化时,这些效应会减弱.

结论:

PRT和TRT增强瘦肉质量,PRT在降低身体脂肪百分比方面显示出明显的优势.
观察到的血清代谢物,特别是HDL成分的改善,似乎与身体组成的同时变化有关.
与TRT相比,PRT可能为身体组成提供更好的好处,对代谢健康有潜在的影响.

Exercise and Muscle Performance

Exercise and Muscle Performance

Exercise induces a range of adaptations in muscle tissue, depending on the type and duration of activity. Such physical training can be broadly categorized into two types: endurance exercises and resistance exercises.
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...
