概括
以速度为基础的训练 (VBT) 协议,以30%的速度损失负面影响划船性能. 在VBT过程中较高的速度损失会损害最大的神经肌肉能力,影响随后的2000米划船人体表性能.
科学领域:
- 体育科学 运动科学 运动科学
- 运动生理学 运动生理学
- 强度和适应条件 强度和适应条件
背景情况:
- 基于速度的训练 (VBT) 用于优化抵抗训练的强度.
- 不同的VBT协议对随后的划船性能和神经肌肉能力的急性影响尚未完全理解.
研究的目的:
- 研究四种不同强度和速度损失的VBT协议对2000米划船人体表 (RE2000) 性能的急性影响.
- 检查这些VBT协议对最大神经肌肉能力的影响,通过负载速度关系 (LVR) 进行评估.
主要方法:
- 15名男性赛事手进行了5个随机方案:单独RE2000 (对照) 和4个VBT方案 (60%或80%的1RM与10%或30%的速度损失),其次是RE2000.
- 使用负载-速度关系 (L0,v0,Aline) 评估最大神经肌肉容量,在每个方案之前和之后的倾斜拉动过程中.
主要成果:
- 随着VBT协议的使用,RE2000计时试验的性能显著减慢,与控制和10%的速度损失协议相比,速度损失为30%.
- 所有方案都显著降低了L0和Aline,表明最大神经肌肉能力受损.
- 与VBT80-10 + RE2000协议相比,在30%的速度损失和控制条件的协议后观察到更明显的阿林减少.
结论:
- 包含30%速度损失的VBT协议严重损害了2000米划船人体表的性能.
- 观察到的性能下降与最大神经肌肉能力的损害有关,特别明显在负载-速度关系 (Aline) 下的区域.
- 教练应考虑VBT中的速度损失参数,以避免对后续划船性能产生负面影响.

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...

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

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.
