코로나 19 시기, 성별과 학교체육 활동 횟수에 따른 중학교 학령기 청소년의 중-고강도 신체활동 특성 분석

국문 초록 (Abstract)

본 연구의 목적은 3차원 가속도계를 활용해 코로나 19 팬데믹 시기 중학교 학령기 청소년의 신체활동을 측정하고 성별과 학교체육 활동 횟수에 따른 MVPA 수준과 특성을 분석하는 것이다. 연구 대상은 남녀 중학생 249명(남: 146명, 여: 103명)이었으며, 3차원 가속도계를 활용해 등교일 5일 간의 신체활동을 측정하였다. 수집된 자료는 신체활동 분석 프로그램(Actilife v.6.11.9)을 활용해, 일일 단위 강도별(좌식, 저강도, 중-고강도)로 분류하였다. 1245건(249명*5일)의 자료 중 오류가 나타난 122건을 제외한 1123건의 측정치를 분석에 활용하였으며, SPSS 20.0 통계프로그램을 활용해 기술통계분석, 이원분산분석(two-way ANOVA), Tukey 사후검증을 실시하였다(p<.05). 분석 결과, 첫째, 청소년 신체활동 기준 달성률은 20.6%(남학생: 24.7%, 여학생: 14.7%)로 나타났다. 둘째, 이원분산분석 결과, 성별(F=22.735, p<.001)과 학교체육 활동횟수(F=17.315, p<.001)에 따른 주효과가 나타났다. 모든 조건에서 성별 차이(남학생>여학생)가 나타났으며, 사후 검증 결과, 학교체육 활동 제공 횟수에 따라 MVPA 시간은 2회 등교일(55.4분), 1회 등교일(43.6분), 0회 등교일(38.8분) 순으로 유의한 차이가 나타났다. 셋째, 성별과 학교체육 활동 횟수 간의 상호작용 효과가 나타났다(F=3.246, p<.05). 코로나 19 팬데믹 기간 동안 우리나라 청소년의 신체활동 수준은 이전에 비해 열악해진 것으로 나타났지만, 학교체육 활동은 청소년의 신체활동 증진에 주요한 역할을 하였다. 마지막으로 제언부에 코로나 19 팬데믹 관련 청소년 신체활동 문제를 분석하기 위한 다차원적인 연구방법의 필요성을 제안하였다.

The purpose of this study is to measure the physical activity of middle school adolescents during the COVID-19 pandemic using a three-dimensional accelerometer, and to analyze the MVPA level and characteristics according to gender and number of school physical activity. The subjects of the study were 249 middle school adolescents (male: 146, female: 103), and the physical activity that occurred during five days of going to school was measured using a three-dimensional accelerometer (GT3X model) developed by Actigraph. The measured data were classified and extracted into three type physical activity(in-active, light, MVPA) per a day using the physical activity analysis program (Actilife v.6.11.9). Out of 1245 data measured for 5 days of 249 people, 1123 cases excluding 122 with errors (364 without SPA(school physical activity), 613 with one SPA, and 146 with two SPA) were used for analysis. Using the SPSS 20.0 statistical program, descriptive statistical analysis, two-way ANOVA, and Tukey"s post-test were performed (p<.05). As a result of the analysis, first, the achievement rate of adolescent physical activity standards was 20.6% (male: 24.7%, female: 14.7%). Second, as a result of two-way ANOVA, the main effect was found according to gender (F=22.735, p<.001) and the number of school physical activities (F=17.315, p<.001). There was a gender difference (male > female) in all conditions, and as a result of the post-test, the MVPA time appeared in that order 2 SPA (55.4 minutes), 1 SPA (43.6 minutes), 0 SPA (38.8 minutes). Third, there was an interaction effect between performance and the number of school physical activity (F=3.246, p<.05). In conclusion, during the COVID-19 pandemic, the level of physical activity among Korean adolescents became worse than before, however, school physical activity was still an attractive activity as a physical activity program. Finally, future research topics were proposed to analyze the problems of adolescent physical activity related to the COVID-19 pandemic.
