Analysis of isokinetic muscle strength for sports physiotherapy research in Korean ssireum athletes

Abstract

[Purpose] The purpose of the present study was to elucidate the muscle conditions such as the isokinetic muscle of Korean ssireum athletes. [Subjects and Methods] This study enrolled 25 elite ssireum athletes. We measured body composition and peak torque at an angular speed at 60°/s using an isokinetic muscle strength dynamometer. [Results] The lean body mass of the left upper limb was significantly higher than that of the right upper limb. However, the lean body mass of the left lower limb was significantly lower than that of the right lower limb. The peak torque for left elbow flexion was significantly higher than that for right elbow flexion. Conversely, the peak torque for left elbow extension was significantly lower than that for right elbow extension. Furthermore, the peak torque for the left knee was significantly lower than that for the right knee for both flexion and extension. [Conclusion] The data from this study elucidate in part the muscle conditions of Korean ssireum athletes, which can be used to establish a reference for the scientific study of sports physiotherapy.

Analysis of the respirogram phase of Korean wrestling athletes compared with nonathletes for sports physiotherapy research

“…Participants were asked to complete a questionnaire via individual in-depth interviews, which took 30 minutes per person 9 ) . There were seven weight categories: gyungjang (less than 75 kg), sojang (less than 80 kg), chungjang (less than 85 kg), yongjang (less than 90 kg), yongsa (less than 95 kg), yeoksa (less than 110 kg), and jangsa (less than 150 kg) 9 , 10 ) . The criteria for the inclusion of participants in the study were as follows: (1) 20–23 years of age, (2) male, (3) history of respiratory disease, (4) experience of stress during exercise, (5) psychological factors, (6) history of injuries, and (7) primary technology used.…”

“…In particular, sports injury in coastal areas is directly or indirectly related to maintenance of athletes’ performance 5 , 6 , 7 , 8 ) . Korean wrestling, also called ssireum, is unique to the traditional culture and folklore of Korean spectator sports 9 , 10 , 11 ) . The rules for matches are simple, and the outcome is clear to young and old observers alike.…”

“…The rules for matches are simple, and the outcome is clear to young and old observers alike. A Korean wrestling match is a gentlemanly sport focused on manners in which the participants do not hit each other 9 , 10 , 11 ) . Male athletes are categorized into seven divisions according to body weight, while female athletes compete in two weight divisions.…”

“…Male athletes are categorized into seven divisions according to body weight, while female athletes compete in two weight divisions. The objective of Korean wrestling is to overcome the opponent by utilizing the muscles of the whole body based on fitness and skill 9 , 10 , 11 ) . Therefore, participation in Korean wrestling results in balanced development of the whole body.…”

“…Therefore, participation in Korean wrestling results in balanced development of the whole body. In Korean wrestling, the participants hold onto each other’s belt (satba) and try to cause part of their opponent’s body above the knee to touch the ground 9 , 10 , 11 ) . Ultimately, the body movements used in the attempt to knock over opponents cause development of muscle strength and endurance 9 , 10 , 11 ) .…”
