The Effects of Continuous Aerobic Training Versus Weight Training with High-Intensity Intermittent Exercise on Physical Performance, Hormonal Responses, and Psychological Fitness in Thai Military

This study aimed to compare the effects of continuous aerobic training (CAT) versus weight training with highintensity intermittent exercise (WT/HIIE) on physical performance, hormonal responses, and psychological fitness in air force men. Forty-one participants were randomly allocated to the control group (CON), CAT, and WT/HIIE. The CAT and WT/HIIE were designed to yield the same energy expenditure/session. Both groups performed 3 times/week for 12 weeks. Results showed that the CON showed no significant change in all parameters. Both CAT and WT/HIIE increased (p<0.05) muscular strength (leg), muscular power, speed, testosterone, testosterone/cortisol ratio, mental state and mental health. Only WT/HIIE decreased (p<0.05) cortisol, stress level and increased (p<0.05) muscular strength (chest), muscular endurance, aerobic capacity, insulinlike growth factor 1, and mental quality. We concluded that both CAT and WT/HIIE were effective in improving physical performance, hormonal responses, and psychological fitness in air force men, but the WT/HIIE appeared to confer greater overall improvements than the continuous aerobic training program.
