The modern fitness culture, propelled by celebrity influence and media exposure, has led to widespread acceptance and consumption of protein supplements, particularly among young adult males aspiring for an ideal physique. Despite the surge in usage, limited research has explored the impact of these supplements on cardiovascular health and exercise performance. This study aims to bridge this gap by clinically examining the cardiovascular system using heart rate variability (HRV) and comparing outcomes between those using protein supplements and a control group.
This study was conducted at the Department of Physiology, AIIMS Raipur. The cross-sectional study involved 60 young adult males aged 18-25 years. Participants were divided into two groups: group I (n = 30), comprising individuals using commercially available protein supplements for a minimum of three months, and group II (n = 30) as age-matched controls. Cardiovascular assessments, including HRV analysis, were performed at rest and after the Harvard step test. Pre-exercise and post-exercise parameters were statistically analyzed, and participants in the test group provided information on supplement labels.
Participants in both groups exhibited comparable pre-exercise cardiovascular parameters. However, post-exercise results did not reveal significant variations in systolic blood pressure, diastolic blood pressure, mean blood pressure, low frequency/high frequency (LF/HF) ratio, Standard deviation of the successive differences between adjacent NNs (SDNN), and standard deviation of successive differences (SDSD) between the test and control groups. The average exercise duration for the control group was longer than that of the test group. Amino acid profiles and nutritional content varied among 13 different protein supplement brands.
The study found no statistically significant positive influence of protein supplements on cardiovascular health or exercise performance in young adult males.
在名人效应和媒体曝光的推动下，现代健身文化使得蛋白质补充剂得到广泛接受和消费，尤其是在渴望拥有理想身材的年轻成年男性中。尽管其使用量激增，但针对这些补充剂对心血管健康和运动表现影响的研究却很有限。本研究旨在通过使用心率变异性（HRV）对心血管系统进行临床检查，并比较使用蛋白质补充剂的人群与对照组之间的结果，以填补这一空白。
本研究在赖布尔全印医学科学研究所生理学系进行。这项横断面研究涉及60名年龄在18 - 25岁的年轻成年男性。参与者被分为两组：第一组（n = 30），由使用市售蛋白质补充剂至少三个月的个体组成；第二组（n = 30）为年龄匹配的对照组。在静息状态和哈佛台阶试验后进行心血管评估，包括HRV分析。对运动前和运动后的参数进行统计学分析，试验组参与者提供补充剂标签上的信息。
两组参与者在运动前的心血管参数具有可比性。然而，运动后的结果显示，试验组和对照组在收缩压、舒张压、平均血压、低频/高频（LF/HF）比值、相邻正常心动周期（NN）之间差值的标准差（SDNN）以及逐次差值的标准差（SDSD）方面没有显著差异。对照组的平均运动持续时间比试验组长。13个不同蛋白质补充剂品牌的氨基酸谱和营养成分各不相同。
该研究发现，蛋白质补充剂对年轻成年男性的心血管健康或运动表现没有统计学上的显著积极影响。
