保持健康的体重需要大量的体力活动. 体重指数 (BMI) 低于25岁,每天至少60分钟进行中等活动的女性保持体重,而其他女性体重增加.
科学领域:
- 运动生理学 运动生理学
- 公共卫生 公共卫生
- 肥胖研究的研究.
背景情况:
- 防止长期体重增加所需的精确体力活动量仍然不确定.
- 目前的联邦指导方针建议每周进行150分钟 (7.5代谢相当的[MET]小时) 的中等强度活动,以获得健康益处.
研究的目的:
- 研究不同程度的身体活动与女性长期体重变化之间的关系.
- 根据身体活动水平,分析饮食典型的女性的体重变化.
主要方法:
- 一项前性队列研究从1992年到2007年跟踪了34 079名健康的美国女性.
- 身体活动 (MET小时/周) 和体重在13年间的多次间隔报告.
- 重复测量回归分析了身体活动和体重变化,每隔3年.
主要成果:
- 在研究期间,女性平均增加了2.6公斤.
- 较高的体力活动水平 (≥21个MET小时/周) 仅在体重指数 (BMI) <25的女性中与较少的体重增加有关.
- 体重指数≥25的女性在体育活动和体重增加之间没有显著的关联.
- 在13年内,13.3%的初始BMI<25的女性实现了体重维持 (体重增加<2.3公斤),平均每周21.5个MET小时 (约1. 60分钟/天) 的时间.
结论:
- 身体活动与BMI<25的女性体重增加的减少有关.
- 在13年内维持正常体重需要每天大约60分钟的中等强度活动.
- 在BMI≥25的女性中,没有观察到身体活动和体重增加之间的显著关联.

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...
