摘要

Wheelchair racing originated from the rehabilitation movement of wounded soldiers after World War II. It is a sport that requires high aerobic ability of athletes. Critical power theory is an evaluation method to evaluate the aerobic capacity of human body. At present, a large number of studies have used the critical power model to predict the training effect, sports performance and sports potential of athletes in different sports (such as swimming, cycling, rowing, etc.), and achieved a certain prediction effect. At the same time, the advantage of using critical power theory to evaluate athletes' aerobic ability is that the test process is convenient and simple, and the test process will not cause any harm to athletes. In the current research, there is a lack of direct research on the speed fatigue time relationship model of wheelchair racing athletes through the critical power theory. The purpose of this study is to investigate the effectiveness of establishing the critical speed model by using six full-strength exercise tests with different constant speeds (80%, 85%, 90%, 95%, 100%, 105% of the speed at exhaustion in the exhaustion speed test); Evaluate the application of these different critical speed models in wheelchair racing; The prediction effect of the parameters obtained from the six exercise tests on the subjects' actual exercise performance of 5000m, as well as the formulation of 5000m competition strategy and training plan were observed.
