增加体重的全身振动 (WBV) 训练在坐期间和之后显著提高了氧气消耗. 30 Hz 频率和 2 mm 幅度的 WBV 有效提高运动强度.
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:
- 全身振动 (WBV) 在训练中越来越多地被用于提高炼结果.
- 了解训练参数如重量和振幅对运动强度的影响,对于优化WBV协议至关重要.
研究的目的:
- 为了研究在全身振动 (WBV) squats期间变化的训练重量和振动振幅对炼强度的影响.
- 为了确定WBV对氧气消耗 (VO2) 和心率反应的影响.
- 在不同的负载条件下评估与WBV部相关的代谢等价物 (MET).
主要方法:
- 负载研究:参与者 (n=10) 在非WBV和WBV (30 Hz,2 mm) 条件下,在0%,40%和80%的体重 (BW) 条件下进行了.
- 幅度研究:参与者 (n=8) 在非WBV,低幅WBV (30 Hz, 2 mm) 和高幅WBV (30 Hz, 4 mm) 的 0% 和 40% BW 条件下进行了.
- 在这两项研究中,对氧气消耗 (VO2) 和心率进行了持续监测.
主要成果:
- 对于运动中和运动后的VO2.2,观察到振动和训练重量之间的显著相互作用效应.
- 80%的WBV地表现出明显更高的运动中的VO2,而40%和80%的WBV地表现出较高的运动后VO2,与非WBV相比.
- 没有发现振幅和训练重量对VO2或心率有显著的相互作用效应;心率对WBV的反应不如VO2明显.
结论:
- WBV坐是一种中等到强烈的强度炼,强度随着更高的训练重量而增加.
- 30Hz频率和2mm幅度的WBV足以在运动期间和之后引起更高的氧气消耗,特别是在增加训练重量时.
- 在WBV条件下,增加训练重量是引起更大的氧气消耗和心率反应的关键因素.

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...
Muscle Stimulation Frequency
Wave summation
At low firing rates, motor neurons induce individual twitch contractions in muscle fibers. These twitches...

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...
Assessment of Ventilation II: Respiratory Depth and Rhythm
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:
Motor Unit Stimulation
The latent period of contraction marks the onset of excitation-contraction coupling, when the action potential propagates across the sarcolemma, preparing the muscle fibers for contraction. As the fibers enter the contraction phase, the...
