Background Cardiometabolic risk factors are a significant health concern, particularly among young adults with overweight and obesity. Concurrent training, which combines aerobic and strength exercise, has been shown to improve cardiometabolic health. However, the effects of different training frequencies are not well understood. Method Forty-three participants (mean age: 19 years) were randomly assigned to either the CT-2 group (concurrent training twice per week, n = 22) or the CT-3 group (concurrent training three times per week, n = 21). The training regimen included 40 minutes of strength training followed by 40 minutes of aerobic exercises. Baseline and eight-week follow-up assessments included anthropometric measurements, body composition analysis, cardiovascular and metabolic parameters, VO2 max, and 1RM squat strength. Results Both the CT-2 and CT-3 groups showed significant improvements in body mass, body fat percentage, fat mass, android fat mass, and gynoid fat mass (p < 0.01). However, the reduction in android/gynoid fat mass ratio was significant only in the CT-3 group (p < 0.05). Additionally, fasting glucose, fasting insulin, total cholesterol, triglycerides, HDL-C, LDL-C, TC/HDL-C, HOMA-IR, HOMA-IS, and HOMA-β levels decreased significantly in both groups post-intervention (p < 0.01). Increases in VO2 max (CT-2: p < 0.05; CT-3: p < 0.01) and 1RM squat strength (CT-2: p < 0.01; CT-3: p < 0.05) were also observed. Comparing the two groups, CT-3 group demonstrated more significant improvements in HDL-C (p < 0.05) and HOMA-IS (p < 0.05). Conclusion These findings highlight the effectiveness of concurrent training in improving cardiometabolic risk factors in young adults with overweight and obesity. Both twice-weekly and three times-weekly training significantly improved these risk factors, with higher frequency training providing additional benefits.
