This paper addresses the dynamic consideration of the athletic constraints on skating motion. In order to generate a human-like skating motion, the athletic constraints are distinctively analyzed into dynamic constraints and physical constraints. A close investigation of the athletic constraints evolved valid extent of dominant parameter for a leg muscle. During the human-like skating motion, the state of actuation was shifted from region of maximum force to region of maximum power. Simulation results were intuitively comprehensible, and the effectiveness of analytic algorithm was demonstrated for skating motion.

The purpose of this study was to explore the relationships between leisure constraint, leisure constraint negotiation and leisure participation of Chinese students studying in Korea. A total of 210 respondents, participating in the athletic competition for Chinese students, were selected to conduct this study, using the purposive sampling method. Finally, 194 surveys except 17 respondents, were used for this study. The reliability of the questionnaire was analyzed using Cronbach's ${\alpha}$ with SPSS 18.0 and the Simple Regression Analysis and Multiple Regression Analysis were conducted. As a result, Main findings were as follows; First, leisure constraint had a positive relationship with leisure constraint negotiation. Specifically, leisure constraint had an influence on 'leisure activity partner search' and 'leisure activity intensity control effort' out of leisure constraint negotiation strategies. Second, leisure constraint had a negative relationship with leisure participation. Third, leisure constraint negotiation had no significant influence on leisure participation.
