본 연구는 건강과 체력과 관련된 신체적 특성과 직접 측정된 최대산소섭취량 간의 관계를 분석하는 것을 목표로 하며, 건강 증진 및 질병 예방을 위한 안전하고 개인화된 체계적인 운동 처방 프로그램 개발을 위한 기초 데이터를 제공하고자 하였다. 연구에는 20대 남성 30명과 여성 11명이 참여했으며 모든 참가자는 체성분, 신체계측, 상하체근력 및 지구력, 그리고 최대산소섭취량, 운동 부하, 심박수, 혈압을 측정하기 위한 점증 운동부하 검사를 수행하였다. 최대산소섭취량와 신체적 특성 간의 관계를 파악하기 위해 상관 분석과 다중 회귀 분석을 실행하였다. 연구결과 체지방률은 최대산소섭취량와 가장 강한 음의 상관관계를 보였으며, 다중 회귀 분석에서도 체지방률은 최대산소섭취량과 유의미한 관계를 보이며 통계적으로 유의했다. 엉덩이 둘레는 최대산소섭취량와 음의 상관관계를 보였으나 신체계측치와 최대산소섭취량 간의 다중 회귀 분석에서는 어떤 항목도 통계적으로 유의미한 결과를 보이지 않았다. 상체 근력은 최대산소섭취량와 가장 강한 양의 상관관계를 보였으나 신체기능과 최대산소섭취량 간의 다중 회귀 분석에서는 통계적으로 유의미한 결과가 나타나지 않았다. 운동 중 최대 수축기 혈압은 최대산소섭취량과 강한 양의 상관관계를 보였으며, 다중 회귀 분석 결과에서도 최대 수축기 혈압는 최대산소섭취량과 유의미한 관계를 보이며 통계적으로 유의했다. 결론적으로 최대산소섭취량와 체지방률 간의 관계의 중요성을 강조하며, 이는 전체적인 건강과 밀접하게 관련되어 있기 때문에 운동 처방 및 프로그램에서 전통적으로 관계가 입증된 최대산소섭취량과 체성분 간의 관계를 고려하는 것 외에도, 근력 및 근지구력 개선과 같은 종합적인 체력 요소도 중요한 건강 관련 체력 요소로 고려할 필요가 있음을 제시한다
Abstract
This study aims to analyze the relationship between subjects’ health, physical characteristics related to fitness, and VO2max measured by direct methods. The goal is to provide foundational data for developing safe, individualized, and systematic exercise prescription programs for health promotion and disease prevention. The study involved 30 men and 11 women in their 20s. All participants underwent measurements of body composition, anthropometry, muscle strength and endurance of the upper and lower extremities, and graded exercise tests (GXT) to determine VO2max, exercise load, heart rate, and blood pressure. Correlation analysis and multiple regression analysis were performed on all measured data to determine the relationship between VO2max and physical characteristics. Body Fat Percentage (%BF) showed the strongest negative correlation with VO2max, with a correlation coefficient of -0.817. The results of multiple regression analysis indicated that %BF had a significant relationship with VO2max, and the p-value was 0.000, which is statistically significant. Hip circumference exhibited a negative correlation with VO2max, with a correlation coefficient of -0.314. However, in the multiple regression analysis involving body measurements and VO2max, no statistically significant results were observed for any of the parameters. Upper body strength showed the strongest positive correlation with VO2max, with a correlation coefficient of 0.578. Nonetheless, the multiple regression analysis of physical function and VO2max did not yield statistically significant results. Maximum systolic blood pressure (SBPmax) during exercise demonstrated a strong positive correlation with VO2max, with a correlation coefficient of 0.787. The results of the multiple regression analysis indicated that SBPmax had a significant relationship with VO2max, with a p-value of0.000, which is statistically significant. This study emphasizes the importance of body fat percentage in relation to VO2max levels, which are known to be closely related to overall human health. Therefore, in terms of exercise prescription and programming, it is desirable to not only consider the relationship between cardiovascular fitness factors, such as VO2max, and body composition, which have traditionally been proven to be related, but also to take into account overall fitness factors, including improvements in strength and muscular endurance, which might otherwise be overlooked as important health-related fitness factors.
