The Effects of a Jump Rope Exercise Program on Body Composition and Self-efficacy in Obese Adolescent Girls

The purpose of this study was to examine the impact of a 12-week jump rope exercise program on body composition, blood pressure, insulin resistance, and academic self-efficacy in prehypertensive adolescent obese girls. Forty-eight prehypertensive adolescent obese girls participated in this study. The girls were randomly divided into the jump rope exercise intervention group (EX, n=24) and control group (CON, n=24). The EX group performed a jump rope training program at 40-70% of their heart rate reserve (HRR) 5 days/week for 12 weeks (sessions 50 minutes in duration). The CON group did not participate in any structure or unstructured exercise protocol. Blood pressure, body fat percentage, waist circumference, blood glucose and insulin, homeostatic model assessment - insulin resistance, and Academic Self-Efficacy were measured before and after the 12-weeks study.
