Completed

• Conditions: Adiposity; Prehypertension; Self Efficacy; Blood Pressure; Abdominal Obesity; Insulin Sensitivity
• Interventions: Other: 12-week jump rope exercise program

• Registration Number: NCT03898518
• Lead Sponsor: Pusan National University

Brief 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.

Group	Intervention	Description
Experimental Group	12-week jump rope exercise program	The experimental group performed the jump rope exercise intervention.

Primary Outcome Measures

Name	Time	Method
Body Fat	12 weeks	Body fat percentage was measured to the nearest 0.1%.
Height	12 weeks	Height was measured to the nearest 1 cm.
Waist Circumference	12 weeks	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.
Lean Body Mass	12 weeks	Lean body mass (kg) was determined using a bioelectrical impedance-meter.
Glucose	12 weeks	Blood glucose concentrations were assessed with a glucose reagent kit.
Insulin	12 weeks	Serum insulin was evaluated using an enzyme-linked immunosorbent assay (ELISA) kit.
Homeostatic Model Assessment - Insulin Resistance	12 weeks	Homeostatic model assessment - insulin resistance was calculated from the fasting plasma blood glucose and insulin levels according to previously established models.
Blood Pressure	12 weeks	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.
Body Mass	12 weeks	Body mass was measured to nearest 0.1kg.
