概括
高强度间歇训练 (HIIT) 和中等强度持续训练 (MICT) 没有显示老年人体育活动的长期差异. 干预组和对照组都在10年内保持了中度至强度的活动.
科学领域:
- 老年学和运动科学
- 公共卫生干预 公共卫生干预
背景情况:
- 迫切需要进行干预措施,以增加体力活动 (PA) 并减少老年人的久坐时间.
- 本研究研究了监督高强度间歇训练 (HIIT) 和中等强度持续训练 (MICT) 对PA和久坐行为的长期影响.
研究的目的:
- 为了比较5年HIIT和MICT与无监督对照组对客观PA和久坐时间的影响.
- 在干预期间和干预期后长达5年的时间 (10年随访) 评估PA和久坐时间的变化.
主要方法:
- 1405名老年人 (平均年龄72.8岁,51%为女性) 随机分为5年,每周进行2次HIIT,MICT或控制 (国家PA建议).
- 使用ActiGraph GT3X+监测器在基线,1,3,5年和10年进行总PA,步骤,静止时间,轻度,中度和强度PA的客观测量.
主要成果:
- 在整个为期10年的研究中,没有观察到群体之间的显著差异.
- 一年后,所有组都显示总血压下降,久坐时间增加,中度血压增加.
- 在10年后,所有组中都保持或增加了聚合中度至强度的PA.
结论:
- HIIT,MICT和对照组在老年人中对客观的PA和久坐时间产生了类似的长期影响.
- 监督和无监督的运动,加上定期的随访,有效地缓解了十年来与年龄相关的中度至强度PA的衰退.

Exercise and Cardiac Output
735
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.

Exercise and Cardiovascular Response
662
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 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 Stress Test
147
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.
