| Abstract |
| High-caloric expenditure (HCE) exercise is an effective strategy to improve body composition and physical performance in overweight individuals. This study evaluated the effects of 12 weeks of multi-modal aerobic training at two different weekly energy expenditure levels: high (3000–3500 kcal/week) and standard (1200–1500 kcal/week) on body composition, aerobic capacity, and functional performance in overweight women. Twenty-seven overweight women (BMI 28.3 ± 2.1 kg/m²; age 34.6 ± 5.2 years) were randomly assigned to HCE (n=9), standard-caloric expenditure (SCE, n=10), or control (n=8) groups. The HCE group completed five weekly sessions, expending 3200 ± 150 kcal/week through walking, cycling, and swimming at 65–85% VO₂max. The SCE group completed three weekly sessions with an average energy expenditure of 1300 ± 120 kcal/week at similar intensities. Controls maintained habitual activity. Outcome measures included body weight, body fat percentage (BFP), muscle mass percentage, VO₂max, plank hold duration, and push-up repetitions assessed pre- and post-intervention. Repeated measures ANOVA revealed significant group × time interactions (p<0.001) for all variables. After 12 weeks, the HCE group showed significant reductions in body weight (4.5 ± 0.8 kg), BFP (5.2 ± 0.7%), and increases in muscle mass (3.8 ± 0.5%), VO₂max (6.5 ± 1.1 ml·kg⁻¹·min⁻¹), plank time (30 ± 4 sec), and push-up count (12 ± 2 reps), all p<0.001. The SCE group exhibited smaller, non-significant changes: weight loss 1.2 ± 0.6 kg, BFP reduction 1.5 ± 0.5%, muscle mass increase 1.0 ± 0.4%, VO₂max increase 2.0 ± 0.9 ml·kg⁻¹·min⁻¹, plank time increase 8 ± 3 sec, and push-up increase 4 ± 1 reps. Controls showed no significant changes. In conclusion, high-caloric expenditure multi-modal training at moderate-to-high intensities (65–85% VO₂max) yields superior improvements in body composition, aerobic capacity, and muscular endurance in overweight women, underscoring its value in obesity management. |
