Sucrose intake by swimming and age-matched sedentary rats. All rats were subjected to this behavioral assessment before swim training (week −1) and then weekly during the 8-week endurance swimming period. The initial training period was the period between weeks −1 and 0. Sucrose intake is usually greater in stressed rats. *P < 0.05, **P < 0.01 compared with age-matched sedentary controls. Some data are presented with their corresponding t and P values
