일회성 경사 트레드밀 걷기운동이 건강한 성인의 운동자각도, 에너지소비량, 근활성도 및 근피로도에 미치는 영향

다국어 초록 (Multilingual Abstract)

Purpose: The purpose of this study is to examine the short-term effects of sloped treadmill walking exercise on rating of perceived exertion, energy expenditure, activity and fatigue of muscles in healthy adults.
Method: Sixteen healthy adults (male: 8, and female: 8) were randomly crossover designed and assigned to the level (LV, 0%), uphill (UH, 10%) and downhill (DH, -10%) treadmill walking exercise. Rating of perceived exertion (RPE), energy expenditure, activity and fatigue of muscles (Erector spinae; ES, Gluteus maximus; GM, Biceps femoris; BF, Gastrocnemius; GCM, Vastus medialis; VM, Vastus lateralis; VL, Tibialis anterior; TA) were measured in repetition (T1~T5) during sloped treadmill walking exercise (1.2 m/sec).
Results: RPE and energy expenditure were significantly increased at UH compared with those of LV and DH (p<.05, respectively). The muscle activity in the VL was significantly higher at T1, T2, T3 and T4 of DH compared with that of LV (p<.05, respectively). The muscle activity in ES, BF, GCM, VM and TA were also significantly increased at T4 compared with that of T1 of LV, UH and DH (p<.05, respectively). In addition, the muscle fatigue in GM and VM were significantly decreased at T3 and T4 of UH compared with that of LV (p<.05, respectively), and the muscle fatigue in ES, BF, GCM and VM were significantly increased at T3 and T4 compared with that of T1 (p<.05).
Conclusion: These results confirmed that RPE, energy expenditure, and muscle fatigue in the VM increased with the time of UH treadmill walking exercise, and the muscle activity in VL was always remarkably higher in DH treadmill walking exercise.
