四足运动训练 (QMT) 显示了中度至非常高的肌肉激活,与传统运动相当或超过. 这种体重训练策略有效地同时参与多个肌肉群.
科学领域:
- 运动生理学 运动生理学
- 生物力学 生物力学
- 运动科学 运动科学 运动科学
背景情况:
- 四足运动训练 (QMT) 被认为可以提高灵活性,功能运动屏幕 (FMS) 评分和自身感知.
- 然而,QMT引起的肌肉激活模式的全面数据仍然有限.
研究的目的:
- 量化比较QMT练习期间关键的上半身,干部和下半身肌肉的表面电肌图 (sEMG) 活动与传统的体重练习 (TRA).
主要方法:
- 20名参与者 (9名男性) 完成了双腿臂,中侧骨,三腕,大胸部,背脊,直腹部,直腿部和双腿部的sEMG评估.
- 参与者在随机顺序下进行了8个QMT练习和3个TRA练习 (俯卧,,前臂板) 的标准重复,其次是最大自发异位收缩 (MVIC) 规范化.
主要成果:
- 在所有测量肌肉群中,在QMT练习中汇集的峰值肌肉激活显示出中度至非常高的水平 (21-60%+MVIC).
- 与俯卧练习相比,QMT诱导的双肩肌,骨肌和背脊肌的峰值肌激活显著更高.
- 此外,QMT也显示出比坐更大的双腿大腿骨激活,而俯卧则引起了更高的三肌和胸部主要激活. 对于腿直体或腹直体,没有发现显著差异.
结论:
- 在QMT期间的肌肉激活与传统的体重炼相当或超过.
- 质量培训提供了一种可行且潜在的吸引力的训练策略,用于同时在多个肌肉群中发展力量.

Exercise and Muscle Performance
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...
Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
