In order to study whether the athletes' special physical fitness and competition load reflect the inherent attributes of sports, this paper puts forward the research on the characteristics of sports, special physical fitness and competition load, and takes the college tennis players in a province as the object. Using themethods of literature, video analysis, experiment, investigation and mathematical statistics, this paper discusses the basic connotation of special physical fitness and competition load, and preliminarilyestablishes the evaluation index system of special physical fitness and competition load. This paper objectively evaluates the special physical fitness and competition load level of college tennis players inJiangsu Province, provides the basis for the training and competition of college tennis players, andhas certain value and significance for enriching and expanding the tennis training theory. The mainconclusions are as follows: calculated from the experimental results, the blood lactic acid level of athletes from the beginning of the competition to the end of the competition is 4.77 + 1.62 mmol / L for menand4.11 + 2.13 mmol / L for women, which is 2-3 times that of quiet. The change of blood lactic acid is relatedto the energy system used during exercise, and also reflects the metabolic rate of muscle fibers.
