Research on the Relationship between Training Duration and Grip Strength Change Based on Grey Relational Analysis

Abstract

With the advent of the information age, modern information technology is progressively influencing the improvement and scientific development of athletes' sports training. The book Sports Training edited by Tian Maijiu points out that strength is the ability of the human body to resist resistance, and it is the basis of physical ability elements such as speed, endurance, agility and flexibility. However, how the grip strength of the athlete changes as the training duration increases is a topic worthy of our study. Regarding the relationship between the two, the coaches usually make subjective judgments based on their own experience; this paper mainly took the maximum grip strength as the research object, and obtained a series of relevant physiological data or indicators by repeatedly testing the maximum grip strength of the testers after a period of grip strength training. Then the data mining algorithm based on Grey Relational Analysis was used to preprocess the data accordingly, thereby extracting useful data on the relationship between training duration and grip strength. Finally, The test data were analyzed and tallied using SPSS 22.0 software, and the following results were finally obtained. The maximum grip strength growth rate was high in the early stage of training (the first 4 weeks); during the test period, the maximum grip strength increased by leaps and bounds, i.e., the maximum growth week occurred, but the individual differences in the appearance time and growth rate were large, showing no significant relationship with gender; the increase in maximal grip strength was characterized by phases during the test period.
