ABSTRACT This study has examined the effect of music Rope-skipping on body composition and health related blood components of middle school students . For this purpose, this research has been aimed at 10 students, 5 males and 5 females of first and second grade in D middle school of B metropolitan city who have not exercised before and agreed to participated in the experiment. The experiment has been performed for 12 weeks, four times a week, 50 minutes per a day, varying the exercise intense depending on preliminary stage, elementary and intermediate stage and conclusion is as follows based on the change in body composition, blood components related to health before and after the experiment.

1. Males showed a decrease of about 2.10kg in body fat mass from pre-test 12.84kg±8.22kg to post-test 10.74±7.41kg: it was not statistically and meaningfully different. Females have a decrease of about 2.64kg from 17.16±5.93kg to 14.52±5.83kg; it was also not statistically and meaningfully different. All males and females showed a drop of about 2.37kg from 15.00±7.13kg to 12.63±6.59kg, but it was not statistically and meaningfully different.

2. The body fat percentage of males decreased from 22.98±9.38% to 19.37±9.04%, the decline of around 3.61% - no statistically meaningful difference. Females fell off by about 4.91% from 32.84±7.57% to 27.93±8.75% but there is no statistically meaningful difference. The whole of male and females showed a decrease of 4.26% from 27.91±9.57% to 23.65±9.24%, there was no statistical meaningful difference.

3. Fat-free mass of males showed a decrease of about 1.82kg from 40.80±9.87kg of pre-test to 42.62±9.46kg of post-test and there was no statistical meaningful difference. As for females, it grew by about 2.38kg from 34.20±1.99kg to 42.62±9.46kg and it was not statistically and meaningfully different. The whole of males and females had an increase of about 2.10kg from 37.50±7.56kg before the experiment to 39.60±7.19kg after the experiment but it was not statistically and meaningfully different.

4. Regarding body-mass index of males, 22.16±5.21kg/m2 dropped to 21.54±4.61kg/m2 on the decrease of about 0.62kg/m2 but it was not statistically and meaningfully different. In case of females, the body-mass index fell off by 0.34kg/m2 from 22.04±3.69kg/m2 to 21.70±3.60kg/m2 but it did not show statistically meaningful difference. All males and females were on the decrease of about 0.48kg/m2 from 22.10±4.26kg/m2 to 21.62±3.90kg/m2 but it was not statistically and meaningfully different.

5. As for hematocrit of males, it was on the increase of 3.90% from 38.96±5.69% to 42.86±4.69% but there was no statistically meaningful difference. Females showed an increase of 5.16% from 35.84±2.63% to 41.00±3.60 % and it statistically and meaningfully increased(p<.05). Both males and females statistically and meaningfully grew by about 4.53% from 37.40±4.49% to 41.93±4.05%(p<.05).

6. The number of erythrocyte in males dropped to 4.54±.35 million/mm2 from 4.56±.67 million/mm2 but it was not statistically different. Regarding females, it was on the increase of 0.62 million/mm2 from 4.11±.35 million/mm2 to 4.73±.70million/mm2, but it was not statistically meaningfully distinctive. The whole of males and females showed an increase of 0.31 million/mm2 from 4.33±.56 million/mm2 to 4.64±.53 million/mm2 but it did not imply statistically meaningful difference.

7. The number of leukocyte in males was on the decrease of about 1.42 103/mm2 from 8.26±2.72 103/mm2 before the experiment to 6.84±.74 103/mm2 after the experiment but it was not statistically and meaningfully different. That of females showed an increase of about 0.16 103/mm2 from 7.02±2.11 103/mm2 to 7.18±.140 103/mm2, but it did not imply statistically meaningful difference. The whole of males and females were on the decrease of about 0.63 103/mm2 from 7.64±2.39 103/mm2 before the experiment to 7.01±1.07 103/mm2 after the experiment but it did not suggest statistically meaningful difference.

8. Concerning hemoglobin of males, it was on the increase of about 3.02g/dl from 12.62±1.79g/dl to 15.64±1.50g/dl and it statistically meaningfully increased(p<.05). Females showed an increase of 2.38g/dl from 11.66±1.15g/dl to 14.04±2.03g/dl and it statistically and meaningfully increased(p<.05). Both males and females showed a statistically meaningful increase of 2.70g/dl(p<.01) from 12.14±1.51g/dl to 14.84±1.88g/dl.

9. The number of thrombocyte was on the increase of about 2.20 103/mm2 from 294.00±53.68 103/mm2 to 296.20±39.81 but it was not statistically and meaningfully different. Regarding females, it was on the increase of about 23.00 103/mm2 from 296.40±62.60 103/mm2 to 319.40±62.69 103/mm2 but it was not statistically different distinctive. All males and females were on the increase of about 12.60 103/mm2 from 295.20±54.99 103/mm2 to 307.80±51.00 103/mm2 but it was not statistically and meaningfully different.

10. Cholesterol in males dropped to 136.20±30.69mg/dl from 159.60±11.33mg/dl on the decrease of about 22.40mg/dl but it was not statistically different. Regarding females, it was on the statistically meaningful decrease of 23.00mg/dl from 159.60±11.33mg/dl to 136.60±17.69mg/dl. The whole of males and females were on the decrease of about 22.70mg/dl from 159.10±25.24mg/dl before the experiment to 136.40±23.61mg/dl after the experiment but it was not statistically and meaningfully different.

11. Blood glucose of males was on the increase of about 11.80mg/dl from 93.80±8.04mg/dl to 105.60±10.62mg/dl but it was not statistically and meaningfully different. Regarding females, it was on the statistically meaningful increase of about 7.20mg/dl from 89.80±5.81mg/dl to 97.00±1.87mg/dl and it implied statistically meaningful increase(p<.05). The whole males and females were on the statistically meaningful decrease of about 9.50mg/dl from 91.80±6.94mg/dl before the experiment to 101.30±8.50mg/dl after the experiment.
