高强度间歇训练 (HIIT) 可能会造成伤害,但维生素C和E补充剂有助于保护运动员. 这些维生素改善了脂质概况和腿部力量,同时减少了运动引起的血液损伤.
科学领域:
- 运动生理学 运动生理学
- 营养生物化学 营养生物化学
背景情况:
- 众所周知,高强度间歇训练 (HIIT) 会诱导运动员的氧化应激和血液学变化.
- 了解抗氧化剂对运动引起的生理变化的保护作用,对于运动员的健康和表现至关重要.
研究的目的:
- 调查8周维生素C和E补充剂对HIIT诱导的脂质谱和血液学变量变化的影响.
- 评估维生素C和维生素E对HIIT运动中的青少年运动员运动表现和健康标志物的综合作用.
主要方法:
- 106名男青少年球员被分为五组:控制组,HIIT,HIIT + 维生素C,HIIT + 维生素E和HIIT + 维生素C和E.
- 8周的干预包括特定的HIIT协议 (90分钟的会议,1:1工作休息比) 和每日维生素补充剂 (1000毫克C,400 IUE).
- 使用标准协议评估脂质概况,血液学变量,最大氧气消耗,垂直跳跃,体重和身体脂肪百分比.
主要成果:
- 所有HIIT组都显示了体重,脂肪百分比,脂质样本 (降低胆固醇/甘油三,提高HDL),最大氧气消耗和垂直跳跃的显著改善.
- 仅HIIT就导致白细胞,红细胞,血红蛋白和血红素的减少,血小板数量增加和血小板与白细胞的比率增加.
- 维生素补充剂 (C,E或两者) 缓解了血液学损伤 (抑制了血液溶解),改善了炎症标志物,增强了腿部力量,而不影响耐力能力.
结论:
- 维生素C和E补充剂有效地防止HIIT诱导的血液损伤,并改善炎症性血液变量.
- 联合补充剂可增强爆炸性腿部强度和脂质配置参数,为从事强度训练的运动员提供显著的健康益处.
- 补充维生素C和维生素E似乎是一种安全有效的策略,可以在不影响耐力的情况下减轻HIIT的负面生理影响.

Blood Studies for Cardiovascular System III: Serum Lipid Profile
Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...
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...

The essential diagnostic tools for detecting myocardial necrosis and monitoring individuals suspected of having acute coronary syndrome (ACS) include:
Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...
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...
