Based on the modem computer technology, mathematical theory and exercise physiol- ogy and biochemistry knowledge, this study used documentary methods, mathematical methods and experimental methods to update and improve the original theoretical system. First, the research chose proper formula models and determined the scoring standard and load standard of intermittent training combined with experts ＇ interviews. Then the research used lsqcurvefit function in Matlab to calculate ＂scoring formula＂ and ＂running curve formula＂, after which the athletes ＇ performances of Tsinghua University were used to assess the validness. Finally the study built new scoring formula and running curve formula and updated scoring tables success- fully, which include 23 items, which could be applied to every athletic level. And new training tables were also formulated including speed table, 400m constant speed table and percentage kilometer speed table, by which the problem of assessing and calculating the sports load will be solved effectively.
