Objective: This study aimed to compare the effect of concurrent training and the addition of health education and nutrition management on body composition and health-related outcomes.
Methods: Twenty-four healthy overweight females (20.42 ± 1.02 years, body mass index [BMI] 25.83 ± 3.63 kg∙m-2) were assigned to a concurrent training group (Exe, n = 12) or a concurrent training and health education group (Exe + Edu, n = 12). Both groups completed 8 weeks of concurrent training (6 days/week), whereas the Exe + Edu participants received additional health education and controlled daily energy intake within the basal metabolic rate. Body composition, serum glucose, lipids and related hormones were measured before and after intervention.
Results: After intervention, the Exe group lost 2.47 kg (±2.46) of body mass, 2.44 kg (±1.71) of total fat mass (FM), corresponding to a body fat percentage (BF%) of 2.25%. Losses of body mass, total FM and BF% in the Exe + Edu group were -5.19 ± 1.87 kg, -4.42 ± 1.83 kg and -4.33 ± 2.39%, respectively. The Exe + Edu participants had significantly greater reductions of body mass, total FM, and trunk and leg FM relative to the Exe participants (p < 0.05). Serum glucose, lipids, insulin and progesterone levels were improved in both groups without group difference.
Conclusion: Concurrent training is an effective short-term training strategy for reducing FM and improving fasting glucose, blood lipids and related hormones. Furthermore, the combination of additional health education can achieve greater effects on weight loss and the reduction of total and regional FM, which may be a better obesity treatment method.
