Exercise 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...

Exercise and Cardiac Output

1.1K
Regular physical activity is essential for maintaining cardiovascular health, with aerobic exercises being particularly effective. According to the American Heart Association, 150 minutes of moderate to intense aerobic exercise per week is recommended for a healthy heart. Aerobic activities may include brisk walking, running, bicycling, cross-country skiing, and swimming, ideally performed three to five times per week.
Sustained exercise increases the muscles' oxygen demand, which can be...

Exercise and Cardiovascular Response

825
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...

概括

对于肥胖的成年人来说,一致的运动时间是可行的和可以接受的,促进中度至剧烈的体力活动 (MVPA). 虽然选择是首选的,但持续的早上或晚上的运动更有效地增加了MVPA.

科学领域:

  • 运动生理学 运动生理学
  • 行为科学 行为科学

背景情况:

  • 观察性研究表明,一致的运动时间可以提高肥胖成年人的中度至强度体力活动 (MVPA).
  • 在自由生活条件下规定的一致运动时间的可行性和可接受性仍然未确立.

研究的目的:

  • 评估在不活跃的肥胖成年人中,在自由生活环境中规定的一致运动时间的可行性和可接受性.
  • 为了比较MVPA的时间处方,并描述炼障碍和促进者.

主要方法:

  • 一个在受试者内部的设计随机选择了15名不活动的肥胖成年人参加3个3周的条件:一致的早晨,一致的晚上和选择时间.
  • 通过预先规定的基准来衡量可行性,通过问卷来评估可接受性和偏好性.
  • 使用加速度计和夜间调查,监测了MVPA,运动时间和障碍物/促进者.

主要成果:

  • 所有可行性基准都达到了,通过加速度计和自我报告,时间遵守超过了60%.
  • 一致的运动时间被认为是可以接受的 (平均评分为3.7/5),尽管选择时间是最喜欢的.
  • 与选择条件相比,一致的早晨和晚上的运动条件对增加MVPA产生了中大影响.

结论:

  • 在自由生活环境中,对肥胖的成年人来说,规定的一致的运动时间是可行的和可以接受的.
  • 持续的时间,特别是早上或晚上,似乎比选择的时间更有效地增加了MVPA.
  • 需要在更大的试验中进行进一步的研究,以确认有效性并探索促进MVPA的机制.
