| Summary: | 碩士 === 國立臺灣師範大學 === 體育研究所 === 89 === The purpose of this study was to investigate the level of vertical jumping patterns in young adults with Down syndrome and the factors influencing vertical jumping pattern. Twelve Down syndrome young adults with middle mental retardation (mean age =18.0±1.7 years) served as participants. Participants were required to perform the highest vertical jump, and movement patterns were video recorded and analyzed. BMI, grip strength, leg strength and range of motion of hips, knees and ankles ere measured, participation’s parents were interviewed to understand the physical activities after schools. The experimental data were processed with statistical methods of Spearman Rank Correlation to investigate the factors influencing vertical jumping patterns. The results were as follows: (1) Vertical jumping patterns of young adults with Down syndrome were immature. The major leg movement pattern was at levelⅡ, the arm movement pattern was at levelⅡ, and the body movement pattern was at levelⅢ. There were intrapattern different in vertical jumping patterns of young adults with Down syndrome. (2) The higher level of leg and body movement patterns of young adults with Down syndrome, the higher vertical jumping height. There were no significant correlation between the level of arm movement pattern and the jumping height. (3) The stronger of leg strength, the higher level of leg movement pattern and body movement pattern. The stronger of arm strength, the higher level of arm movement pattern. There were no significant correlations between the levels of movement pattern and the rest of test items. (4) Full movement experiences may improve the level of vertical jumping patterns, particularly in the skill of vertical jump.
