2.3.1. Dietary Records
All the participants maintained their usual dietary habits throughout the experiment, except for the intake of dairy products being prohibited for one week prior to the experiment. The dietary analysis was conducted by the weighted food records based on a 2-day food diary (2 random days per week). Fluid consumption and snack intake were also recorded on the same day. Daily nutritional intake was analyzed using the Dietary Analysis and Management System for Athletes (developed by the National Institute of Sports Medicine, Beijing, China).
