Effects of Self-Myofascial Released and Sports Massage on Exercise Performance and Fatigue Recovery in Male College Students
젖산에 대한 연구는 1907년 플레처(Fletcher)와 홉킨스(Hopkins)에 의해 시작되었고, 실험과정에서 젖산이 산소와 밀접한 관련이 있음을 보고하였다. 이후 여러 연구를 통해 젖산이 근 피로를 유발하는 물 질로써 무산소성 해당과정에 의한 부산물로 인지하였다. 1970년대 이후 '젖산혁명(lactate revolution)'이 제기되었고, 이와 관련하여 Brooks et al. 은 lactate shuttle theory를 발표하면서 젖산을 피로물질 이 아닌 에너지원이며, 세포 내의 산증(acidosis)으로부터 근 섬유를 보호하는 물질로써, 포도당이 분해되는 일시적인 상태로[7,8] 정의 PURPOSE: The purpose of this study was to investigate the effects of self-myofascial release exercise (SMR) and sports massage (SM) treatment
... ge (SM) treatment on exercise performance and fatigue recovery in male college students. METHODS: Twelve male college students (23.41±1.24 years, 174.33±6.75 cm, 71.57±9.63 kg, 17.01±6.48% fat) participated in the study. Subjects were randomly assigned to either an experimental treatment (SMR or SM) or control (CON). All subjects were performed with 1st treatment (CON, SMR, SM) for 10 minutes in the lower limbs before isokinetic exercise and Wingate test. After 1 st treatment, Wingate test was performed for 30 seconds after performing isokinetic exercise at 240°/sec left and right 28 times. After isokinetic exercise and Wingate test (All-out), 2nd treatment was performed for 10 minutes. In order to analyze creatine kinase (CK) and lactate, blood was collected and measured 9 times in total. RESULTS: There was no significant difference in the left and right endurance, maximal power, and total workload of the extension and flexor muscles measured by isokinetic exercise. In addition, there was no significant difference in the mean power (p=.116), maximum power (p=.214), fatigue index (p=.236), and total workload (p=.108) during Wingate test. In the case of CK and lactate levels, there was also no significant difference in treatment (CON, SMR, SM) and interaction effect except over time (p=.000, p=.000 respectively). CONCLUSIONS: In conclusion, it seems that fatigue recovery and exercise performance are not affected by self-myopia relaxation exercise and sports massage treatment for 10-minute before and after exercise.
