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.
