在康复和运动科学领域，对运动反应的综合评估对于准确制定运动计划非常重要。乳酸盐是临床实践中经常测量的重要能量底物，因为它提供了有氧能力的信息。唾液乳酸，可以测量非侵入性，最近已被集中作为血液乳酸的替代品。本研究旨在确定体脂、身体含水量和骨骼肌质量指数对唾液乳酸峰值水平的综合影响。37名非运动员男性进行蹲跳练习。在运动前、运动后立即和运动后每5分钟使用一个简化的装置测量他们的唾液乳酸水平。我们还评估了身体成分。以唾液乳酸峰值水平为因变量，以体脂比、身体含水量和骨骼肌质量指数为自变量进行线性多元回归分析。参与者的体脂率（正效应; p = 0.001）和身体含水量（负效应; p = 0.035）显著影响唾液乳酸盐峰值水平。骨骼肌质量指数倾向于积极影响唾液乳酸水平（p = 0.099），虽然不显着。模型的校正R平方值为0.312（p = 0.001）。体脂、身体含水量和骨骼肌质量指数对唾液乳酸峰值水平的综合影响为31.2%。更好的营养指导可能有效地促进减肥和增加身体含水量，以提高康复环境中的有氧能力。
In the rehabilitation and sports science fields, comprehensive assessment of the response to exercise is important for accurately prescribing exercise programs. Lactate is an important energy substrate that is frequently measured in clinical practice because it provides information on aerobic capacity. Salivary lactate, which can be measured non-invasively, has recently been focused on as an alternative to blood lactate. This study aimed to determine the combined effects of body fat, body water content, and skeletal muscle mass index on peak salivary lactate levels. Thirty-seven non-athletic males performed a squat jump exercise. Their salivary lactate levels were measured before, immediately after, and every 5 min after the exercise using a simplified device. We also assessed body composition. A linear multiple regression analysis was performed with peak salivary lactate levels as the dependent variable and body fat ratio, body water content, and the skeletal muscle mass index as independent variables. The participants’ body fat ratio (positive effect; p = 0.001) and body water content (negative effect; p = 0.035) significantly affected peak salivary lactate levels. Skeletal muscle mass index tended to positively influence salivary lactate levels (p = 0.099), albeit not significantly. The adjusted R-squared value of the model was 0.312 (p = 0.001). The combined effect of body fat, body water content, and skeletal muscle mass index on peak salivary lactate levels was 31.2%. Better nutritional guidance may be effective in promoting weight loss and increasing body water content to improve aerobic capacity in the rehabilitation setting.
