RESTORATIVE EFFECT OF JOGGING ON LOWER LIMB MUSCLES

Abstract

ABSTRACT Introduction: Jogging can be a great way to improve physical condition, boosting mind and body. Its method of movement is simple, and there are no sporting limitations as to age, gender, or training place. Jogging is believed to help repair muscle and joint injuries in the lower limbs. Objective: To explore the effects of running on recovering lower limb muscles. Methods: We surveyed 60 undergraduate students who took a 400-meter test at the same site. According to the test results, they were divided into low, medium, and high fitness levels. A questionnaire survey was also used with 20 undergraduate students from the Physical Education Department. Four groups of volunteers did some jogging exercises. Physiological, biochemical, and muscle strength measurements were performed after jogging. The data were statistically treated. Results: The magnitude of change in the sagittal angle of the knee and ankle joint did not increase significantly with increasing jogging rate. The changes in the sagittal angles of the hip, knee, and ankle joints were the same for the volunteers with different jogging rates. After 60 minutes of exercise, the low-fitness group showed faster breathing, an elevated heart rate, and a higher rate of lactate and creatinine in the blood. After 120 minutes of exercise training, all sedentary volunteers showed an increase in lactate, creatinine, respiratory rate, and heart rate (P<0.05). The test performance started to decrease at 400 meters. Conclusion: The maximal activation of different parts of the locomotor system changed under different rates of movement. Brief, controlled jogging may be beneficial to lower limb muscles. Still, long-term jogging may cause even more damage to the body and deleterious changes to rehabilitation in blood and biochemical parameters.
