概括
干部和上肢的肌肉强度显著影响站立远跳的表现. 在这项针对健康成年人的研究中,肌肉质量没有显著影响.
科学领域:
- 生物力学 生物力学
- 人类表现的人类表现.
- 运动生理学 运动生理学
背景情况:
- 肌肉力量和质量是运动表现的关键决定因素.
- 干部,上肢和下肢肌肉对站立远跳的具体贡献尚未完全理解.
- 站立式远跳整合了整个身体,而不仅仅是下肢.
研究的目的:
- 为了研究肌肉力量和来自干,上肢和下肢的质量对站立远跳的表现的影响.
- 为了确定哪些身体部分的肌肉力量和质量最能预测跳跃能力.
主要方法:
- 31名健康的年轻人 (18名男性,13名女性) 参加了这项研究.
- 测量干部,上肢 (抓住) 和下肢 (膝盖延伸) 的肌肉力量.
- 使用身体成分分析仪评估干部,上肢和下肢的肌肉质量.
- 评估的站立远跳性能 (跳跃力).
- 使用多重回归分析来确定影响因素.
主要成果:
- 多重回归分析表明,干部肌肉强度 (β = 0.367,p = 0.006) 和上肢肌肉强度 (β = 0.608,p < 0.001) 是站立远跳表现的显著预测因素.
- 这些因素解释了站立远跳表现变异的57.4% (调整后R2 = 0.574,p < 0.01).
- 在本分析中,检查的身体部位的肌肉质量并不是一个重要的因素.
结论:
- 干部和上肢肌肉力量是站立跳远表现的关键决定因素.
- 虽然下肢的强度在直觉上很重要,但干部和上肢的强度在本研究中表现出更大的影响.

Exercise and Muscle Performance
1.6K
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...

Muscle Stimulation Frequency
2.6K
The contraction strength of muscles is regulated by motor neurons, which modulate the frequency of action potentials dispatched to the motor units based on the body's requirements. This process of varying the muscle stimulation frequency allows muscles to contract with a force that is precisely tailored to the needs of the moment, whether lifting a feather or a heavy box.
