전신 크라이오테라피 처치 강도에 따른 대학축구선수의 뇌산소포화도, 심박수 및 체온의 변화 = Changes in Brain Oxygen Saturation, Heart Rate, and Body Temperature of College Football Players according to Whole-Body Cryotherapy (WBC) Intensity

국문 초록 (Abstract)

이 연구의 목적은 전신크라이오테라피(Whole Body Cryotherapy, WBC / 이하 WBC) 처치 강도에 따른 대학축구선수의 뇌산소포화도, 심박수 및 체온 변화에 대하여 알아보는데 있었다. 연구의 대상자는 하루 일정이 모두 동일한 스케줄로 통제되는 대학축구부 선수 10 인이었으며, ‘저강도 WBC’와 ‘고강도 WBC’에 각 5명씩 무선할당 되었다. 본 연구의 종속변인은 뇌 활성도를 알 수 있는 뇌산소포화도, 심박수, 그리고 신체 총 네 부위의 체온이었다. 뇌산소포화도의 경우 WBC 처치 전, 처치 중, 처치 직 후의 총 세 시점을 기준으로 측정하여 비교하였으며, 심박수와 체온의 경우 WBC 처치 전, 처치 후의 총 두 시점을 비교하여 제시했다. 연구 결과 측정한모든 변인에서 통계적인 차이가 나타났다. 뇌산소포화도의 경우 집단, 시점, 집단과 시점에 따른 상호작용 모두 통계적으로 유의한 차이가(p<.000) 나타났으며, 저강도 집단이 고강도 집단에 비해 WBC 처치 전·중·후 간의 비교에서 더 큰 폭의 뇌산소포화도 감소가관찰되었다. 심박수의 경우 두 집단 모두에서 처치 전·후 간 차이(p<.05) 가 나타났으며, 체온의 경우 대흉근에서 저강도 WBC 집단을 제외한 모든 신체 부위 및 집단에서 처치 전·후 간 차이(p<.01, p<.05, p<.000)가 나타났다. 크라이오테라피는 그동안 다양한 분야에서 학술적인 연구가 이루어져 왔고, 현재는 의학 및 스포츠 분야에서 널리 활용되고 있으나, 축구선수를 대상으로 처치 강도에 따른 뇌산소포화도, 심박수 및 체온의 변화를 살펴본 연구는 전무한 실정이었다. 그동안 크라이오테라피의 효과는 주로 근육 회복과 염증 감소에 초점이 맞춰져 왔으나 본 연구는 그 영향력을 뇌 기능 차원으로 확장하고자 과학적 근거자료를 제시했다는 점에서 의미가있다.

다국어 초록 (Multilingual Abstract)

The purpose of this study was to investigate changes in brain oxygen saturation, heart rate, and body temperature in college football players according to the intensity of Whole-Body Cryotherapy (WBC/hereinafter referred to as WBC) treatment. The subjects of this study were 10 players from college football teams whose daily schedules were all controlled by the same schedule, and five players were wirelessly assigned to 'low-intensity WBC' and 'high-intensity WBC'. The dependent variables of this study were brain oxygen saturation, heart rate, and body temperature in a total of four areas of the body, which indicate brain activity. In the case of brain oxygen saturation, it was measured and compared based on a total of three points before WBC treatment, during treatment, and immediately after treatment, and in the case of heart rate and body temperature, a total of two points before and after WBC treatment were compared and presented. As a result of the study, statistically significant differences were found in all measured variables. In the case of brain oxygen saturation, there was a statistically significant difference in both groups, time points, and interactions according to groups and time points (p<.000), and a greater decrease in brain oxygen saturation was observed in the low-intensity group in the comparison between before, during, and after WBC treatment compared to the high-intensity group. In the case of heart rate, the difference between before and after treatment in both groups (p<.05) was found, and in the case of body temperature, differences (p<.01, p<.05, p<.000) were found before and after treatment in all body parts and groups except for the low-intensity WBC group in the great thoracic muscle. Cryotherapy has been studied academically in various fields and is now widely used in the medical and sports fields, but there have been no studies examining changes in brain oxygen saturation, heart rate, and body temperature according to treatment intensity in soccer players. Until now, cryotherapy's effects have mainly focused on muscle recovery and inflammation reduction, but this study was meaningful in that it presented scientific evidence to expand its influence to the level of brain function.
