概括
高强度阻力和冲击训练 (HiRIT) 改善了超越有氧训练 (AT) 的步伐速度,在肥胖的老年人中进行了减肥. 这两种干预都是安全的,并导致类似的体重减少.
科学领域:
- 老年学和运动生理学
- 肥胖和体重管理
- 肌肉骨健康 肌肉骨健康
背景情况:
- 为了减肥而限制能量可以导致肌肉和骨质量损失,增加肉类和骨质疏松症的风险.
- 高强度阻力和冲击训练 (HiRIT) 可能有助于减少体重减轻期间肌肉骨的衰退.
研究的目的:
- 为了比较HiRIT与有氧训练 (AT) 对肥胖的老年人进行饮食减肥的身体功能和身体组成的影响.
主要方法:
- 60名患有肥胖和运动限制的老年人 (≥60岁) 被随机分配到12周的监督HiRIT或自我指导的AT计划中.
- 参与者食用低热量饮食 (减少750-1000千卡/天).
- 主要结果是步行速度的变化;身体组成和其他身体功能措施也被评估.
主要成果:
- 与AT相比,HiRIT显著提高了步行速度 (0.07m/s的差异).
- 两组都在椅子上站立的时间有所改善;HiRIT还增加了手握强度和短物理性能电池 (SPPB) 评分.
- 这两种干预措施都导致了总体体重,脂肪量,内脏脂肪和尾性瘦肉量相似的减少.
结论:
- 在减肥期间,HiRIT比AT更安全,更有效地提高肥胖老年人的步行速度.
- 需要进一步研究更大的样本大小和更长的持续时间来确认HiRIT对肌肉和骨质的好处.

Exercise and Muscle Performance
1.3K
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 Cardiovascular Response
659
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...
