The effect of skipping on strength and flexibility 12-14 year old male basketball players

Methods: A total of 24 athletes between the ages of 12-14 participated in the study. Participants were divided into two equal groups as 12 experiment (X age = 12.92; sd = .79) and 12 control (Xage = 12.92; sd =, 79) groups. While the control group continued their routine basketball training, the experimental group was included in the eight week skipping rope training program. In two groups, pre-test and post-test data were recorded as height-body weight, 30 m Sprint test and Sit-and-reach flexibility test. Findings: In the experimental group, an increase above the rates 10 m. sprint (z = -2,49, p < 0,05), 10-30 m. sprint (z = -2,39, p < 0,05) ve Total 30 m. sprint (z = -3,06, p < 0,01) occured. In the control group, there was only a slight increase in 10 m sprint (z = -2.35, p <0.05) and no significant difference was found in 10-30 m and total 30 m sprint rates. A decrease compared to pretest data occured in the experimental group Sit-reach (z = -2.58, p <0.05), Flexibility-right (z = -2.98, p <0.01) and Flexibility-left (z = -3.13, p <0.01) data. In the control group, it was determined that there was no significant difference in the measurements of Sit-reach (z = -, 85 p> 0.05) and Flexibility-right (z = -1.18, p> 0.05) .In the flexibility-left data, a statistically significant difference was found between the pretest and posttest measurements of the control group (z = -2.44, p <0.05). Conclusion : It was observed that the strength values of the group skipping rope increased and their flexibility values decreased compared to basketball players who did not jump rope. In the control group, there was no increase or decrease in strength and flexibility values in general. However, the increase in the 10 m sprint value and the decrease in the flexibility-left value are thought to be due to the content of basketball-specific training during the study.
