这项研究发现,碳水化合物循环氨酸补充剂在连续炼期间不会显著改善CrossFit运动员的表现. 虽然在跳跃功率上发现了一些轻微的改善,但整体的代谢和性能影响是不确定的,需要进一步研究.
科学领域:
- 运动科学 运动科学 运动科学
- 运动生理学 运动生理学
- 营养科学 营养科学
背景情况:
- 碳水化合物补充在体育运动中是常见的,用于提高表现.
- 环氧是一种碳水化合物,因其潜在的 ergogenic 作用而引起了人们的注意.
- 穿越健身训练涉及高强度,多样化的功能运动,需要大量的能量和恢复.
研究的目的:
- 为了研究循环二烯碳水化合物摄入量对十字运动员表现的影响.
- 在连续的高强度炼期间,评估环素对强度,功率和代谢标志物的影响.
- 为了确定循环德林补充剂是否在CrossFit环境中提供人体效益.
主要方法:
- 一项随机,双盲,交叉研究,涉及21名男性CrossFit运动员.
- 运动员接受了30g的环氧 (Cluster Dextrin®) 或安慰剂 (Bolero Advanced Hydration®).
- 通过每天两次20分钟的炼 (WOD),反运动跳跃 (CMJ),Wingate测试,1次RM长椅压力和手握强度以及血糖和乳酸盐测量来评估表现.
主要成果:
- 在cyclodextrin和安慰剂组之间,在CMJ时间,身高或功率 (W/Kg) 中没有发现显著差异.
- 统计学上显著的CMJ跳跃功率 (W) 的百分比改善 (p < 0.05),表明潜在的性能好处.
- 套件中的执行速度在WOD前后呈现出差异,在两种条件下观察到每次重复的下降,但没有证实循环二的整体显著性能或代谢增强.
结论:
- 在测试的方案中,补充30g的环氧氨酸并没有在CrossFit运动员中显示出显著的代谢或提高表现的效果.
- 虽然观察到CMJ功率的一些孤立改善,但总体数据表明,环氧可能不是这种人群和训练风格的强有力的人体效应辅助剂.
- 需要进行进一步的研究,以探索在高强度间歇训练环境中使用环氧的潜在益处和最佳方案.

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...
