- This study aimed at providing a reference for the selection of energy tonics for sportsmen engaging in high-strength training and competitions by investigating the effects of the intake of beverages containing glycerinum before exercise at high temperature on the physical functions of bicyclists. Forty bicyclists were selected as research subjects and divided into a test group and a control group. The indexes such as urine volume, weight loss value, oxyhemoglobin saturation, blood lactic acid, nervous tension difference value and reaction time were detected after the sportsmen took different beverages. The conclusions were drawn after the data were analyzed by SPSS ver. 18.0. The research results demonstrated that, the intake of beverages containing glycerinum could reduce urine output and lower weight loss value, prolong the endurance riding time of bicyclists in high temperature environment, reduce the concentration of blood lactic acid, improve the aerobic exercise ability of sportsmen, relieve nervous tension and fatigue, and improve physical functions.
