概括
在老年人中,与重力 (GR) 训练相比,同惯性 (IN) 训练在异常功率增益方面表现出一些优势,特别是在侧向运动中. 然而,这两种训练方法在整体体能和降低跌倒风险方面都同样有效.
科学领域:
- 老年学与运动科学
- 生物力学和运动控制
- 运动医学与康复
背景情况:
- 衰老与肌肉力量的下降有关, 阻力训练对于预防至关重要.
- 中老年人受益于有针对性的运动干预措施,以维持身体功能并降低跌倒风险.
研究的目的:
- 为了比较同惯性 (IN) 训练与重力 (GR) 训练在活跃的中年成年人肌肉力量和体力表现的有效性.
- 评估IN和GR培训对该人群中与跌倒风险相关的变量的影响.
主要方法:
- 一项为期6周的随机对照试验,涉及57岁以上的44名体育活跃成年人.
- 参与者被分配到异惯性 (IN) 或重力 (GR) 训练组,每周进行3次运动.
- 主要结果:异常功率 (通过IN和GR系统评估);次要结果:同心功率,物理性能和跌倒风险变量.
主要成果:
- 在使用IN系统进行评估时,与重力训练相比,同等惯性训练显示出更大的异常功率增益,而侧向运动则具有统计学意义.
- 在使用GR系统评估的异常功率,同心功率,物理性能或跌倒风险变量方面没有发现显著差异.
- 在所有测量结果中,这两组培训都比基线显著改善.
结论:
- 虽然同惯性训练可能为异常动力提供特定的优势,特别是在某些运动中,如侧向冲刺,但其优越性在所有测量中都没有得到一致的证明.
- 无论是异惯性训练还是重力训练,都在提高活动中年人的总体偏心力 (用GR系统评估时),同心力,体力表现以及降低跌倒风险因素方面显得同样有效.

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...

Isotonic and Isometric Muscle Contractions
4.0K
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.
