The establishment of critical power model of dragon boat athlete and practical research

Through reading critical power theory (CP: Critical Power) related domestic and foreign literature material, and against the characteristics of energy supplement in different distance, exploring the training methods of athletes´ physical ability by using the dragon boat dynamometer. the research established related mathematical model between P-T; D-T; D-P; P-D^-1. Research shows that: 1) P-T is nonlinear model, the curve bottom near critical power points. 2) D-T linear model, slope of linear model represents the critical power value. 3) D-P model is nonlinear, critical power (CP) value is the hyperbolic function of a relation with power (the horizontal axis) intersections. 4) P-D ^-1 model is linear, the intercept represents athletes aerobic work ability, the function of the slope represents athletes anaerobic working ability.
