概括
高强度间歇训练 (HIIT) 根据工作和休息时间,会对运动后恢复产生不同的影响. 在HIIT中较短的工作间隔可能会提高神经肌肉恢复与持续负荷炼相比.
科学领域:
- 运动生理学 运动生理学
- 运动科学 运动科学 运动科学
- 神经肌肉功能 神经肌肉功能
背景情况:
- 总体工作通常被认为是运动后恢复的主要驱动力.
- 在高强度间歇训练 (HIIT) 期间的工作和休息时间可以影响生理压力和恢复.
- 了解这些细微差别对于优化培训和恢复策略至关重要.
研究的目的:
- 为了研究神经肌肉功能在工作休息后的恢复时间过程,与不同工作间隔持续时间的HIIT协议相匹配.
- 为了比较不同HIIT协议和常量负载 (CL) 循环之间的恢复动力学.
- 确定工作间隔时间对中部和外围神经肌肉恢复的影响.
主要方法:
- 12名参与者 (6名女性) 进行了登陆式增量测试,以确定峰值功率输出 (PPO).
- 参与者在90%的PPO下完成了三个自行车程序:3分钟工作/3分钟休息HIIT (HIIT3min),1分钟工作/1分钟休息HIIT (HIIT1min) 和持续负载 (CL).
- 神经肌肉功能通过在基线的最大自愿收缩 (MVC) 和大腿神经刺激,任务失败 (TF) 和TF+1,+4,+8分钟来评估.
主要成果:
- 在TF的所有条件下,MVC力在TF+8分钟时以类似的方式减少,TF+8分钟时部分恢复.
- 引起的肌肉抽力在CL后比HIIT1min在TF下降了更多,并在TF+8min内恢复得更快.
- 自发激活在HIIT1min的TF下降,但不是HIIT3min或CL,在TF+8min时完全恢复.
结论:
- 神经肌肉恢复动力学在持续负荷运动和工作之间有所不同:休息与HIIT协议相匹配.

Muscle Recovery and Fatigue
4.0K
Muscle fatigue refers to the decline in a muscle's ability to maintain the force of contraction after prolonged activity. It primarily stems from changes within muscle fibers. Even before experiencing muscle fatigue, one may feel tired and have the urge to stop the activity. This response, known as central fatigue, occurs due to changes in the central nervous system, namely the brain and spinal cord. While there is no single mechanism that induces fatigue, it may serve as a protective...

Fatigue
796
Fatigue occurs when materials rupture under repeated or fluctuating loads, even at stress levels far below their static breaking strength. It typically results in brittle failure, even for ductile materials. It is a critical consideration in designing machines and structural components subjected to repetitive or varying loads. The nature of these loadings can range from fluctuating loads like unbalanced pump impellers causing vibrations to repeatedly bending a thin steel rod wire back and forth...

Exercise and Muscle Performance
2.3K
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...

Fatigue Strength of Concrete
538
Fatigue, in the context of materials science and engineering, refers to the weakening or failure of a material caused by repeatedly applied loads, even if these loads are below the strength limit of the material. Fatigue strength in concrete is a critical property that influences its durability and longevity. Concrete can fail in two ways due to fatigue. Static fatigue or creep rupture occurs under a constant load or one that increases slowly. The other failure mode is due to cyclical or...
