概括

八周的高强度间歇训练 (HIIT),水中和陆地,改善了中年男性的血液动力学和血管功能. 水中HIIT在减少身体脂肪和增强血管内皮功能方面表现出卓越的结果.

科学领域:

运动生理学运动生理学
心血管健康心血管健康
体育科学运动科学运动科学

背景情况:

身体活动较低的中年男性往往会经历低于最佳的心血管和血液动力学参数.
高强度间歇训练 (HIIT) 被认为具有改善健康标志物的潜力.
研究水上与陆地HIIT的比较效果对于优化运动处方至关重要.

研究的目的:

为了比较水中HIIT与陆地HIIT对中年男性血液动力学和血管功能的8周影响.
为了确定水中环境是否为这些生理结果提供比陆地培训更好的优势.

主要方法:

30名中年男性被随机分配到水中HIIT组或陆地HIIT组.
两组都在八周内每周三次进行HIIT.
血液动力学 (血压,心脏功能) 和血管功能 (动脉直径,口腔疾病,PWV) 在干预前和后被测量.

主要成果:

这两种训练方式都显著改善了身体组成 (体重,BMI,体脂率),心脏功能 (中风量,心脏输出量),血液动力学 (血压) 和血管功能 (FMD).
与陆地HIIT相比,水中HIIT在身体脂肪率,中风体积,心率,血压,壁应力,缩速度峰值和流量介导扩张方面显著改善.
水中HIIT还导致左心室体积和分数缩短的更有利的变化.

结论:

八周的水上和陆地HIIT有效地提高了中年男性的身体组成,血液动力学和血管功能.
水中HIIT似乎产生了卓越的益处,特别是在减肥和血管内皮功能方面,这可能是由于水中环境的水静压和热效应.

Exercise and Cardiovascular Response

Exercise and Cardiovascular Response

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...

Exercise and Cardiac Output

Exercise and Cardiac Output

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...
