Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Control Group

The control group was in the facility for all jump rope exercise sessions but did not participate in the exercise intervention.

Group Type NO_INTERVENTION

No interventions assigned to this group

Experimental Group

The experimental group performed the jump rope exercise intervention.

Group Type EXPERIMENTAL

12-week jump rope exercise program

Intervention Type OTHER

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.
