An excessively sedentary lifestyle is associated with many negative health consequences, including musculoskeletal diseases. Dietary branched-chain amino acids (BCAAs) play an important role in muscle metabolism and function.
The aim of this study was to evaluate the relationship between dietary BCAA intake and triceps and biceps brachii upper extremity muscle tone, stiffness, and elasticity measured by hand grip strength (HGS) and MyotonPro.
In this cross-sectional study, data collected from 76 young women aged 18-24 years were analyzed. To collect the data, the Descriptive Information Form, International Physical Activity Questionnaire-Short Form (IPAQ-SF), and food frequency questionnaire (FFQ) were used. The participants' height, body weight, HGS, and muscle viscoelastic properties were measured. In data analysis, descriptive statistics and both simple and multiple linear regression analyses were performed.
The mean total BCAA intake of the participants was 11.2 ± 3.6 g/day. The dietary BCAAs intake was significantly positively related to HGS (Model 1 (β, 0.286; p < 0.05), Model 2 (β, 0.444; p < 0.05)). The dietary total BCAAs intake was significantly positively related to biceps brachii tone (Model 1 (β, 0.304; p < 0.05), Model 2 (β, 0.457; p < 0.05)), biceps brachii stiffness (Model 1 (β, 0.293; p < 0.05), Model 2 (β, 0.525; p < 0.05)), and triceps brachii stiffness (Model 1 (β, 0.345; p < 0.05), Model 2 (β, 0.363; p < 0.05)), whereas dietary BCAAs were not related to biceps brachii elasticity, triceps brachii tone, and elasticity (p > 0.05).
The results of the study support the potential effects of dietary BCAA intake on HGS, muscle tone, and stiffness characteristics in sedentary young women.
久坐不动的生活方式会带来许多负面健康后果，包括肌肉骨骼疾病。膳食支链氨基酸（BCAAs）在肌肉代谢和功能中发挥着重要作用。
本研究旨在评估膳食BCAA摄入量与通过握力（HGS）和MyotonPro测量的肱三头肌和肱二头肌上肢肌张力、僵硬度和弹性之间的关系。
在这项横断面研究中，分析了从76名年龄在18至24岁的年轻女性中收集的数据。为收集数据，使用了描述性信息表、国际体力活动问卷简表（IPAQ-SF）和食物频率问卷（FFQ）。测量了参与者的身高、体重、HGS和肌肉粘弹性特性。在数据分析中，进行了描述性统计以及简单和多元线性回归分析。
参与者的平均总BCAA摄入量为11.2±3.6克/天。膳食BCAAs摄入量与HGS显著正相关（模型1（β，0.286；p<0.05），模型2（β，0.444；p<0.05））。膳食总BCAAs摄入量与肱二头肌张力（模型1（β，0.304；p<0.05），模型2（β，0.457；p<0.05））、肱二头肌僵硬度（模型1（β，0.293；p<0.05），模型2（β，0.525；p<0.05））和肱三头肌僵硬度（模型1（β，0.345；p<0.05），模型2（β，0.363；p<0.05））显著正相关，而膳食BCAAs与肱二头肌弹性、肱三头肌张力和弹性无关（p>0.05）。
该研究结果支持了膳食BCAA摄入量对久坐不动的年轻女性的HGS、肌张力和僵硬度特征的潜在影响。
