CORRELATION BETWEEN DURATION SPENT IN FITNESS CENTER AND VO2 MAX LEVEL AMONG ADULTS

VO 2 max or oxygen consumption maximum value is a gold standard indicator towards cardiovascular and aerobic endurance because it refers to the maximum amount of oxygen used by an individual in one minute during maximum physical activity. The study purpose was to see the correlation between duration spent in the fitness center and VO 2 max value among adults. This study used analytical study method, cross-sectional type. We chose the participant from members of Gold’s Gym fitness center at Cihampelas, aged 18-45 years old, with 3 months minimum of activity, and exercise frequency around three times per week. The participants who had the cardiovascular and pulmonary disease, serious physical injury, had already exercised during the time of observation, or professionally trained athletes were excluded. We used Queen College step test for the instrument. There were 47 participants in this study. Spearman’s correlation coefficient was calculated to measure the correlation between duration spent and VO 2 max, and the result was 0.77(95% CI 0.64; 0.85), p<0.001 which is categorized as strong correlation. From this study, we found that with the increase of duration spent in the fitness center, the VO 2 max level is also increasing, and vice versa. This result is supported by a study from the United States which finds a correlation between VO 2  max and performance times of recreational triathletes. In conclusion, there is a positive correlation between duration spent in the fitness center and VO 2 max level among adults.
