Abstract

Combined exercise (CE) may offer benefits beyond aerobic exercise (AE) alone for individuals with overweight or obesity, but comparative evidence remains uncertain. We performed a systematic review and meta-analysis of randomized trials comparing CE with AE in adolescents and young adults aged 6-45 years. Twenty-nine studies involving 1,383 participants were included. Compared with AE, CE was associated with greater improvements in lean body mass and insulin-resistance indicators, including insulin and HOMA-IR. No consistent between-group differences were observed for body weight, BMI, body fat percentage, waist circumference, systolic blood pressure, or lipid outcomes, while HDL-C showed a small difference favoring AE. Secondary and exploratory analyses should be interpreted cautiously because several outcomes were supported by limited studies and low-to-very-low certainty evidence. These findings suggest that CE may be useful for selected body composition and metabolic outcomes, but does not appear universally superior to AE.
