Athletes are required to obtain comprehensive and diverse physical skills to succeed in aesthetic group gymnastics. The importance of speed is elaborated especially during jumps and turns in the routines. The aim of this study is to increase knowledge on technical aspects of jumps to support coaches of aesthetic group gymnastics. This study examines speed as a success factor and how take-off\u2019s ground contact time impacts the jump height, the amplitude of the jump and how fast the gymnasts can perform their maximum amplitude during the jumps flight time. In this study amplitude means lower limbs\u2019 movement range.\nThe participants included 63 gymnasts from Finnish teams competing in the senior category. The subjects performed a split jump from two-foot take-off, of which their jump height was measured with photocells. The amplitude, take-off speed and the time from take-off to maximum amplitude in flight was analysed from video recording. In addition, subjects\u2019 flexibility was measured from over split. \nAs a result of this study, the take-off time did not influence the jump\u2019s height. However, the take-off time did influence the speed at which the maximum amplitude was obtained during the jump's flight time and the participants with faster take-off accomplished the maximum amplitude of the jump faster. Flexibility influences the jump's amplitude, the more flexible gymnasts had larger amplitude in their jump. Amplitude also correlates with jump height, and the subjects/participants with higher jumps showed larger amplitude in their jumps.\nAs a conclusion, take-off time does influence the speed of how fast the maximum amplitude can be accomplished during jump\u2019s flight time. Flexible gymnasts are able to achieve larger amplitude in split jump and the higher the jump the larger amplitude the gymnasts can perform.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Miia Hakanen (mihakane@jyu.fi) on 2019-07-05T10:56:41Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2019-07-05T10:56:41Z (GMT).
