Estimated power output for a distance run and maximal oxygen uptake in young adults

Both cardiopulmonary exercise testing (CPET) and run field tests are recommended by the American Heart Association for assessing the maximal oxygen uptake (VO max) of youth. Power output was highly correlated with VO max in CPET. However, it is unclear regarding the correlations of time and estimated power output (EPO) for a run field test with VO max obtained from CPET in young adults. This study included 45 participants, aged 20-40 years, from a sample of 1,120 military personnel who completed a 3,000-m run field test in Taiwan in 2020. The participants subsequently received CPET using the Bruce protocol to assess VO max in the same year. According to the physics rule, EPO (watts) for the run field test was defined as the product of half body mass (kg) and [distance (3000-m)/time (s) for a run field test]. Pearson product-moment correlation analyses were performed. The Pearson correlation coefficient (r) of time against EPO for the run field test was estimated to be 0.708 (
