渐进的超负荷显著提高了抵抗训练的肌肉生长. 然而,即使没有渐进的超负荷,训练仍然可以诱导年轻女性的肌肉缩.
科学领域:
- 运动生理学 运动生理学
- 肌肉缩 肌肉缩 肌肉缩
- 运动科学 运动科学 运动科学
背景情况:
- 渐进的超负荷是抵抗训练的基石原则,以促进肌肉生长.
- 了解其对缩的具体影响对于优化训练计划至关重要.
- 之前的研究已经确定过载的好处,但直接比较与非进步方法是必不可少的.
研究的目的:
- 为了研究逐渐超负荷对阻力运动诱导的肌肉生长的影响.
- 为了比较渐进性超负荷 (PO) 与非渐进性超负荷 (N-PO) 对肌肉缩的影响.
- 为了确定没有超负荷进展的训练是否足以诱导肌肉缩.
主要方法:
- 55名未经训练的年轻女性参加了为期8周的单边肘部延伸研究.
- 参与者被分配到渐进性过载 (PO),非渐进性过载 (N-PO) 或对照组.
- 在特定的解剖点使用超声波测量三头臂肌肉厚度.
主要成果:
- 与对照组相比,PO和N-PO两组都显示了三臂肌肉厚度的显著增加.
- 渐进性超负荷组表现出明显更大的肌肉厚度增加比非渐进性超负荷组.
- 肌肉生长依赖于过载原理的剂量,PO产生较高的缩.
结论:
- 渐进的超负荷在促进肌肉缩方面比没有超负荷进展的训练更有效.
- 没有逐渐超负荷的阻力训练仍然可以在年轻,未经训练的女性中诱导显著的肌肉缩.
- 需要进一步的研究来确定非渐进性抵抗训练对肌肉生长的长期疗效.

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...
