Does the Weighted Rope Jump Training Affect the Motor Skills in Adolescent Female Volleyball Players?

Physical Fitness Promotion among Adolescents: Effects of a Jump Rope-Based Physical Activity Afterschool Program

“…Interestingly, the waist circumference of the traditional jump rope group increased significantly (7.88%; d = 0.84) while other two groups had no significant changes. The findings contradicted previous studies’ results that jump rope-based interventions significantly reduced participants’ body fatness [ 25 , 39 ]. This might be due to different measures, in which body mass index (BMI) was frequently used in the previous research [ 25 , 39 ].…”

“…The findings contradicted previous studies’ results that jump rope-based interventions significantly reduced participants’ body fatness [ 25 , 39 ]. This might be due to different measures, in which body mass index (BMI) was frequently used in the previous research [ 25 , 39 ]. Although it might be difficult to elucidate this contradictive result, our study recognized that the participants’ waist circumferences were within the non-risky range of overweight or obese (≤88.9–101.6 cm) [ 56 ].…”

“…This finding also supports previous literature that suggests that jump-based PA intervention can enhance adolescents’ standing long jump performance [ 39 ]. Interestingly, Colakoglu et al [ 39 ] applied heavy jump ropes (weight: 1.3–1.5 lb) to the weighted jump rope group to compare the effects of 15 min of jump rope training with other groups (standard jump rope group and control group), and found a significant increase in standing long jump among the female student athletes from the weighted jump rope group. Although our study used standard jump ropes (weight: 0.2–0.4 lb) for both intervention groups, the intervention groups’ performance in the standing long jump was significantly improved.…”

“…Consistent with previous study [ 39 ], jump rope-based intervention groups (freestyle rope skipping and traditional jump rope) demonstrated significant improvement in hand grip strength compared to the control group. Specifically, students in the freestyle rope skipping group considerably enhanced their hand grip strength (right hand: 12.28%, d = 0.41; left hand: 13.38%, d = 0.42), and the traditional jump rope group’s students also notably increased their hand grip strength (right hand: 11.41%, d = 0.44; left hand: 9.79%, d = 0.31).…”

“…Both left- and right-hands grip strength (kg) were measured three times in a standing position, and the highest number was used for the final data analyses in this study. Previous research showed that the standing long jump and handgrip tests were highly reliable and valid for measuring muscular strength [ 39 ].…”
