主要方法:
- 十一名休活动的男性完成了三个会议:控制,低负荷RT (30% 1RM,高体积),和高负荷RT (90% 1RM,低体积).
- 测试涉及连续的背,长椅压力,死,军事压力和腰排到意志疲劳,休息间隔为90秒.
- 运动后2小时内测量氧气消耗 (V·O2) 和基质利用率.
主要成果:
- 低负荷 (30% 1RM) 和高负荷 (90% 1RM) 两种RT都显著增加了运动后的氧气消耗 (V·o2) 与对照组相比,运动后一两个小时.
- 对于两种RT协议来说,运动后一小时脂肪氧化显著增加.
- 与高负荷RT和对照相比,低负荷RT在运动后两小时显示脂肪氧化升高的时间更长.
结论:
- 完成高负荷和低负荷阻力炼方案以对意志疲劳产生积极影响后炼新陈代谢.
- 与高负荷,低体积的训练相比,低负荷,高体积的耐力训练会引起更持久的代谢适应,特别是脂肪氧化,而不是高负荷,低体积的训练.

01:27Exercise and Muscle Performance
1.4K
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...

01:20Exercise and Cardiovascular Response
787
Exercise significantly impacts cardiovascular response, which is crucial for understanding patient health and designing effective treatment plans.
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...

01:24Muscle Recovery and Fatigue
2.1K
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...

01:18Metabolic States of the Body: The Postabsorptive State
300
The postabsorptive state usually starts about four hours after a meal and lasts until the next meal is eaten. During this time, the digestive system stops absorbing nutrients, and the body uses stored energy reserves to maintain stable blood glucose levels.
Initially, glycogen stored in the liver is broken down to release glucose into the bloodstream, while glycogen in the muscles is broken down to supply glucose for energy directly within the muscle cells. As glycogen stores diminish,...

Introduction
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.
