요가 수르야 나마스카 동작의 숙련도 차이에 따른 ROM과 근활성도 비교 = Comparison of Rom and muscle ativities according to the skills of surya namaskara in vinyasa yoga

다국어 초록 (Multilingual Abstract)

The purpose of this study was to investigate rang of motion (ROM) and muscle activities according to the skills of Surya Namaskara in Vinyasa Yoga. six females (skilled 2, unskilled 4) of university students were participated in this experiment. The dependent of research were ROM and muscle activities for static poses on Surya Namaskara in Vinyasa Yoga. The six infrared cameras (Oqus 300, Qualisys Inc, Sweden) and Zero Wire EMG (Aurion, Italy) were used to acquire raw data, and the Qualisys Track Manager and Noraxon (MyoResearch XP Master Edition, USA) were used to process data. The %MVIC and ROM, research variables were analyzed with Visual 3D (C-Motion Inc, USA) and Noraxon.
The conclusions were as follows :
First, the skilled performed ranges of motions for joints of Surya Namaskara greater than the unskilled in Vinyasa Yoga, that is, the skilled had more flexible than the unskilled.
Second, muscle activities of skilled women's Surya Namaskara lesser than the unskilled in Vinyasa Yoga, that is, muscle activities of the skilled had smaller than the unskilled because of repetitive training.
Third, it is necessary that instructors give the subjects special training methods which are suitable to them so as to perform chair, stick, and warrior pose of Surya Namaskara like skilled women's motions that decrease muscle injuries in Vinyasa Yoga.
In conclusion, ROM and %MVIC between two groups were remarkable different according to the static poses of Yoga, therefore instructors have to provide step-by-step information that was suitable to themselves (ROM and EMG of poses).
