Physiological changes in the exhaustive submaximal endurance and resistance exercises. (A) Heart rate at rest and after the exhaustive submaximal endurance exercise. (B) Cortisol levels in the sera at rest, and 0 and 30 min after the submaximal endurance and resistance exercises. *represents statistical significance with “rest” (P<0.05). # represents statistical significance with “rest” (P<0.01). %HRmax: percent of maximal heart rate. 85% VO₂max: 85% of maximal oxygen consumption. 85% 1-RM: 85% of one repetition maximum. Recovery: time point at 30 min after each exercise.
