윈게이트 파워 테스트시 피부 Cooling 처치가 무산소 능력 및 하지 근활성도에 미치는 영향 = Effect of the Cooling treatments on anaerobic power and lower limb muscle activities in a wingate power test

다국어 초록 (Multilingual Abstract)

Purpose : The purpose of this study was to examine the effects of the cooling treatments on anaerobic power and lower limb muscle activities in a wingate power test.

Methods : Fourteen healthy college students aged 22 to 24 at K University participated in the study(Age: 23.3 ± 1.2 years, Height: 177.6 ± 8.9 cm, Weight: 72.3 ± 11.7 kg, BMI: 21.8 ± 3.2). After attaching an electrode to the lower limb muslce, skin temperature treatment(32℃) and cooling treatment(-15℃) were performed. and the experiment was conducted randomly. A total of two wingate power tests were performed for 30 seconds to measure average power maximum anaerobic power, minimum anaerobic power, average iEMG, and peak iEMG of lower limb muscles(rectus femoris, vastus medialis, vastus lateralis, biceps femoris).

Result : During the wingate test, there was no significant difference between treatment in the average power(t=1.080, p= .297), the maximum power(t=1.143, p= .271) minimum power(t= .430, p= .674). In case of average iEMG, there was no significant difference between treatment in rectus femoris(t=-1.110, p= .744),vastus medialis(t=-.487, p= .540), vastus lateralis(t=-.273, p= .693), biceps femoris(t= .732, p= .325). Also there was no significant difference between treatment in peak iEMG of rectus femoris(t=1.027 p= .348),vastus medialis(t=-.603, p= .463), vastus lateralis(t=-.382, p= .540), biceps femoris(t=1.163, p= .360).
Conclusions : The results of this study are summarized as follows. First, there was no significant difference in the anaerobic power(mean power, peak power, minimum power) by cooling trearment. Second there was no significant difference in average IEMG and peak IEMG. It is considered that there is no significant difference as the deep body temperature rises due to the exertion of maximum force in a short period of time without oxygen supply in the wingate test. It is believed that delaying the time to reach fatigue by preventing the body temperature from rising rapidly with cooling treatment during exercise breaks will have a positive effect on the anaerobic ability,
