概括
延长状态异常训练 (LSET) 显著增强了腿筋和双腿骨长头 (BFlh) 肌肉的大小和力量,比北欧腿筋训练 (NHT) 更多. 在运动员中,LSET可以提供对腿筋损伤的优越保护.
科学领域:
- 运动医学 运动医学
- 运动生理学 运动生理学
- 生物力学 生物力学
背景情况:
- 腿筋肌肉对于冲刺至关重要,但容易受到压力损伤,特别是双腿骨长头 (BFlh).
- 建议以古怪的重点训练来增强肌肉适应性和伤害预防.
研究的目的:
- 为了比较两个不同的异常训练计划对腿筋肌肉适应的影响.
- 为了评估北欧腿筋训练 (NHT) 与延长状态异常训练 (LSET) 对肌肉大小,力量和BFlh 肌神经区域的影响.
主要方法:
- 42名健康的男性被分为LSET,NHT或对照 (CON) 组12周.
- 磁共振成像 (MRI) 评估了肌肉体积和BFlh 脊髓神经瘤区域.
- 最大膝盖屈曲扭矩被测量为偏心,同心和同度.
主要成果:
- LSET显示,腿筋肌肉总体体积 (+18%对 +11%的NHT) 和BFlh肌肉体积 (+19%对 +5%的NHT) 的增长优异.
- 此外,LSET还产生了更大的BFlh神经瘤区域增长 (+9%对NHT的+3%).
- 显而易见的缩模式出现了:LSET倾向于肌肉也延伸部,而NHT倾向于那些不.
结论:
- 在诱导腿筋缩和BFlh肌肉缩方面,LSET比NHT更有效.
- 这些发现表明,与NHT相比,LSET可能为冲刺表现和腿筋伤害预防提供了更好的好处.

Exercise and Muscle Performance
1.4K
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...

Isotonic and Isometric Muscle Contractions
3.0K
Two primary types of muscle contractions are isotonic and isometric, each serving unique functions and involving distinct mechanisms. Both isotonic and isometric contractions are integral to the body's complex system of movement and stability. Isotonic exercises contribute significantly to functional strength and movement, while isometric contractions are crucial for maintaining posture and joint stability.
