Clinical Trial Summary

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.

Intervention

Other:
• 12-week jump rope exercise program
Each jump rope exercise session of the program was performed for 50 minute, with a 5 minute warm-up and cool-down. Sessions were performed once a day, 5 days a week, for 12 weeks. The program consisted of various main jump rope exercises (1 line 2 jump, jumping feet together, running jumping, open side jump, open back and forth jump, rock paper scissor jump). The warm-up and cool-down consisted of static stretching, walking, and jogging. Intensity of exercise was gradually increased form 40-50% heart rate reserve (HRR) in weeks 1-4 and 60-70% HRR in weeks 9-12. Each training session was supervised by the researchers. Ever subject wore a heart rate monitor during the whole training session in order to maintain the designated training intensity.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Body Fat	Body fat percentage was measured to the nearest 0.1%.	12 weeks
Primary	Blood Pressure	Blood pressure was measured in duplicate using an automated sphygmomanometer. The average of the was recorded as the resting blood pressure. Both systolic and diastolic blood pressure were recorded.	12 weeks
Primary	Body Mass	Body mass was measured to nearest 0.1kg.	12 weeks
Primary	Height	Height was measured to the nearest 1 cm.	12 weeks
Primary	Waist Circumference	Waist circumference as measured at midpoint between the lower rib and the iliac crest at the end of a normal expiration using a tap measure.	12 weeks
Primary	Lean Body Mass	Lean body mass (kg) was determined using a bioelectrical impedance-meter.	12 weeks
Primary	Glucose	Blood glucose concentrations were assessed with a glucose reagent kit.	12 weeks
Primary	Insulin	Serum insulin was evaluated using an enzyme-linked immunosorbent assay (ELISA) kit.	12 weeks
Primary	Homeostatic Model Assessment - Insulin Resistance	Homeostatic model assessment - insulin resistance was calculated from the fasting plasma blood glucose and insulin levels according to previously established models.	12 weeks
