The aim of this study was to analyze the effects of hydrolyzed collagen supplementation on body composition, neuromuscular fitness and cardiorespiratory fitness in active subjects undergoing a 24-week training program. A randomized, double-blind, placebo-controlled trial was conducted in 90 adults aged 45-65 with osteoarticular discomfort, including 45 men and 45 women. Participants received either 10g of hydrolyzed collagen enriched with minerals and vitamins (experimental group, EG), or a placebo (control group, CG), while following a twice-weekly training program. Physical performance was assessed through grip strength, squat jump (SJ), counter-movement jump (CMJ), and a cardiopulmonary exercise test. Biochemical and hematological analyses were also conducted. Significant improvements were observed in CMJ for the EG (p = 0.032), with men showing greater gains than women (p = 0.049). No significant differences were found in SJ between groups. After 24 weeks, 72.1% of the EG reported improved musculoskeletal discomfort, compared to only 10.3% of the CG. The study suggests that collagen supplementation may enhance muscle performance, likely by promoting connective tissue remodeling and increasing tendon elasticity. However, training alone improved overall physical condition in all participants.
本研究的目的是分析补充水解胶原蛋白对参加为期24周训练计划的活跃受试者的身体成分、神经肌肉适应性和心肺适应性的影响。对90名年龄在45 - 65岁、患有骨关节不适的成年人进行了一项随机、双盲、安慰剂对照试验，其中包括45名男性和45名女性。参与者在遵循每周两次训练计划的同时，接受10克富含矿物质和维生素的水解胶原蛋白（实验组，EG）或安慰剂（对照组，CG）。通过握力、深蹲跳（SJ）、反向移动跳（CMJ）和心肺运动试验评估身体表现。还进行了生化和血液学分析。实验组的CMJ有显著改善（p = 0.032），男性的改善幅度大于女性（p = 0.049）。两组之间的SJ没有显著差异。24周后，72.1%的实验组报告肌肉骨骼不适有所改善，而对照组只有10.3%。该研究表明，补充胶原蛋白可能通过促进结缔组织重塑和增加肌腱弹性来增强肌肉性能。然而，仅训练就改善了所有参与者的整体身体状况。
