摘要
迟发性肌肉酸痛(DOMS)是一种常见的疾病,其特征是在剧烈或不习惯的运动后肌肉僵硬、疼痛和炎症。尽管其普遍存在,但DOMS的潜在机制仍不清楚。本研究旨在探讨补充胶原蛋白对运动训练个体迟发性肌肉酸痛相关的组织修复和疼痛的影响。方法:14名接受运动训练的男性(n=7)和女性(n=7)被纳入一项随机、平衡、交叉试验。参与者被分配到乳清蛋白组(n=8)或胶原蛋白组(n=6)。每个参与者连续四天每天食用40克各自的蛋白质补充剂。使用自我报告评分和算法测量来评估峰值酸痛。统计分析包括独立样本t检验和Levene方差相等检验。结果:分析显示,乳清蛋白组和胶原蛋白组在24小时时间点的疼痛峰值无显著差异(t(12) = 1.33, p = 0.208)。两组在24小时内都经历了高峰疼痛的减少,但两组之间的减少没有统计学差异。在测量的其他变量中未观察到显著差异。结论:这些发现表明,与补充乳清蛋白相比,在运动训练的个体中,补充胶原蛋白并没有显著减少与迟发性肌肉酸痛相关的峰值。虽然补充胶原蛋白已显示出对组织修复和关节健康的潜在益处,但需要进一步研究其对DOMS的具体影响。为了更全面地了解胶原蛋白对肌肉酸痛和组织修复的影响,有必要对不同剂量和参与者群体进行更大规模的研究。
A Pilot Study of the Effects of Collagen vs. Whey Protein Supplementation on Delayed Onset Muscle Soreness in Healthy Individuals
Introduction: Delayed onset muscle soreness (DOMS) is a common condition characterized by muscle stiffness, pain, and inflammation following intense or unaccustomed exercise. Despite its prevalence, the underlying mechanisms of DOMS remain unclear. This study aimed to investigate the effects of collagen supplementation on tissue repair and pain associated with DOMS in exercise-trained individuals. Methods: Fourteen exercise-trained men (n=7) and women (n=7) were enrolled in a randomized, counterbalanced, crossover trial. Participants were assigned to either a whey protein group (n=8) or a collagen protein group (n=6). Each participant consumed 40g of their respective protein supplement daily for four consecutive days. Peak soreness was assessed using self-reported ratings and algometer measurements. Statistical analysis included independent samples t-tests and Levene's test for equality of variances. Results: The analysis revealed no significant difference in peak soreness between the whey protein and collagen protein groups at the 24-hour time point (t(12) = 1.33, p = 0.208). Both groups experienced a decrease in peak soreness over the 24-hour period, but the reduction was not statistically different between the groups. No significant differences were observed in other variables measured. Conclusions: These findings suggest that collagen protein supplementation did not significantly reduce peak soreness associated with DOMS compared to whey protein supplementation in exercise-trained individuals. While collagen supplementation has shown potential benefits in tissue repair and joint health, further research is needed to explore its specific effects on DOMS. Larger studies with different dosages and participant populations are warranted to obtain a more comprehensive understanding of collagen's impact on muscle soreness and tissue repair.
