Abstract

The research aims in general to identify the differences between the types of tactical plans for the race strategy and the significance of their variation in the dimensions of the predictive and correlative contribution to some kinematic properties of the arms and the amounts of movement and stress and critical speed rates and the digital level in the Olympic Games in Tokyo 2021 AD in the digital level of the 200-meter freestyle swimmer (the research sample), and the researcher used Analytical descriptive approach for 30 freestyle 200m swimmers 10 swimmers for each tactical strategic plan, the results of which came in the first order (negative segmentation) by maintaining energy reserves until the end of the race, especially in the third, fourth and 200m 50m in all variables with the largest contribution ratios without stress, then (regular stride) in varying and close proportions, especially for the 50m The first, second and third are below the fourth 50m, then (positive segmentation) in the end because they lack energy in the third and fourth 50m and affected the total 200m.
