Abstract

This study was applied to the people with mental retardation with the aim of to verify the effectiveness of the Inline-Skate exercising program. It was conducted on 16 male in an elementary school students(10~12 age), for 50min, 3times/week, for 12 weeks. The results of this study are as follows;1. In the physique, there was significant difference in the height(t=-6.49, p<.001), head circumference(t=-4.95, p<.001), chest circumference(t=-2.36, p<.01), thigh circumference(t=-6.85, p<.001) of the experiment group. And there was significant difference in the height(t=-6.84, p<.001), head circumference(t=-7.51, p<.001), chest circumference(t=-3.08, p<.01), upper-arm circumference(t=-6.26, p<.001), thigh circumference(t=-4.53, p<.001) of the control group.2. In the physical-fitness, there was significant difference in the strength(t=-15.76, p<.001), static muscular endurance(t=-4.21, p<.001), power(t=-5.14, p<.001), flexibility(t=-4.47, p<.001), balance(t=-2.84, p<.01), %fat(t=6.67, p<.001) and muscle volume(t=-2.86, p<.01) of the experiment group. And there was significant difference in the strength(t=-5.77, p<.001), static muscular endurance(t=-7.93, p<.001), power(t=-4.68, p<.001), flexibility(t=-3.08, p<.001), balance (t=-4.82, p<.001) of the control group.3. In the BMD, there was significant difference in the BQI(t=-3.83, p<.001), SOS(t=4.12, p<.01), BUA (t=-3.47, p<.01) in the experiment group. And there was significant difference in the BQI(t=5.06, p<.001), SOS(t=3.12, p<.01), BUA(t=5.14, p<.001) in the control group.
