As teen obesity rates continue to climb, we need to explore all means of preventing obesity-related diseases in youth. A study published inMedicine & Science in Sports & Exercise (2015; 47 , 2636–44) adds further support in favor of promoting strength training among this at-risk group.
The study aimed to understand the benefits of a 12-week resistance training program for 24 nondiabetic, obese teens around 14 years old. The primary outcome measures included endothelial function, body composition, metabolic profile, and strength and aerobic fitness. Twenty nonobese teenagers served as a control group.
By the end of the 12 weeks, the obese students had made significant improvements in body fat, waist circumference, waist-to-hip ratio, endothelial function, hemodynamic and metabolic profiles, and overall fitness. There were no noteworthy differences between pre- and post-intervention body mass.
The authors emphasized that resistance training alone can be highly beneficial in helping obese teenagers experience health improvements.
