SPORT KINESIOLOGY BASED ON THE CONCEPT OF HEALTH AND FITNESS

ABSTRACT Introduction: Exercise is the most effective way to improve physical fitness. One can achieve the effect of wellness and fitness through scientific exercise. Running is a relatively common method of physical exercise. It plays a significant role in improving physical fitness. Objective: This study aimed to investigate the characteristics of lower extremity movements during running. The results of this study may provide better exercise planning for runners. Methods: This paper selects several runners as the research subject. The subjects started running after attaching a motion detector sensor patch to their body. Then, this paper collected kinematic data. The kinematic data includes the joint angles and range of motion (ROM) of the hip, knee, and ankle joints. Results: There was no significant difference in the distribution of peak tibial acceleration, plantar pressure, and maximum pressure of athletes under different track materials (P>0.05). There was a significant age difference between the hip and knee joints of the athletes in the overhead stage (P<0.05). Conclusion: There may not be a necessary connection between ground and lower limb impact in running athletes. Through its adjustment, the human body can dampen the load effect of the foot contact surface. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.
