概括
甲素 (PC) 补充剂改善了CrossFit运动员的表现,并减少了肌肉疼痛. 这项研究发现,PC增强了腰强度和跳跃性能,同时降低了延迟发作的肌肉疼痛 (DOMS).
科学领域:
- 运动生理学 运动生理学
- 运动营养 运动营养
- 人类表现的人类表现.
背景情况:
- 甲素 (PC) 可能通过减少感知到的劳累和肌肉损伤来改善高强度运动.
- 通过提高性能和恢复,PC补充可以使CrossFit (CF) 运动员受益.
研究的目的:
- 调查PC补充剂对表现,恢复和CrossFit课程期间代谢反应的急性影响.
主要方法:
- 一个随机的,三重盲目的,安慰剂控制的交叉研究,涉及50名训练有素的CrossFit运动员.
- 参与者在标准化CF会议之前45分钟服用2.5毫克PC或安慰剂,包括举重和WOD.
- 评估了表现 (坐,反运动跳跃),肌肉疼痛 (DOMS) 和生理标志物 (心率,乳酸,RPE).
主要成果:
- 与安慰剂相比,PC显著改善了70%的1RM地表现 (负载和重复) 和减弱的反运动跳跃下降.
- 随着时间的推移,PC保持了举重表现,并且在会后的24小时和48小时,延迟发作的肌肉疼痛 (DOMS) 显著降低.
- 在男性中,PC降低了CMJ损失,在女性中增加了坐负荷,乳酸,RPE,PRS或心率没有显著差异.
结论:
- 急性素补充剂有效地提高了CrossFit运动员的表现并加速了恢复.
- 在高强度训练环境中,PC显示出作为改善力量,功率和减少肌肉损伤的补充剂的潜力.

Alleles are different forms of the same gene. Humans and other diploid organisms inherit two alleles of every gene, one from each parent.
02:07Blind Procedures
Ideally, the people who observe and record the children’s behavior are unaware of who was assigned to the experimental or control group, in order to control for experimenter bias. Experimenter bias refers to the possibility that a researcher’s expectations might skew the results of the study. Remember, conducting an experiment requires a lot of planning, and the people involved in the research project have a vested interest in supporting their hypotheses. If the observers knew which child was...
01:16Crossover Experiments
Crossover experiments, also called the repeated-measurements design, is a study design in which all experimental units are exposed to all treatments in different periods. Crossover experiments are generally used in psychology, the pharmaceutical industry, agriculture, and medicine.
Crossover designs are performed even with smaller sample sizes since the samples can act as their controls. These are better than simple randomized trials since patients are exposed to all the treatments.
