Abstract:This study aims to identify the advantages of biomehcanics from plyometric Olympic weightlifting movement in explosive strength training through sports biomechanics experiment. 10 college student-athletes were recruited as research subjects, and they were asked to conduct explosive strength training which contains power cleans, power snatches, plyometric power cleans, and plyometric power snatches during different load conditions. The sports biomechanical characteristics of different movements were compared by using mathematical statistics and machine learning algorithm and the results showed that under moderate relative load, the plyometric power snatch had biomechanics advantages, while at high relative load, the plyometric power clean had biomechanical advantages. The lower limb kinematics of Olympic weightlifting movements and their plyometric variations were similar, but when performing explosive strength training at moderate and submaximal intensity loads, the differences in lower limb joint kinematic patterns between plyometric power movements were smaller. The conclusion revealed that the plyometric Olympic weightlifting movement has the significant sports biomechanical advantages in explosive strength training, and given that, it is recommended to develop a personalized training protocol according to the needs and skills from the weightlifting trainers.
