PURPOSE: This study aimed to evaluate the validity of the 5-minute running test (5RFT) as a field-based assessment of aerobic fitness by examining its correlation with maximal oxygen uptake (VO2max) measured using the Bruce protocol.
METHODS: Twenty-one healthy male participants majoring in physical education at S University completed both the 5RFT and a laboratory-based VO2max test using the Bruce protocol. During the 5RFT, oxygen consumption was measured using a portable metabolic gas analyzer (K5, COSMED, Italy). VO2max values from the 5RFT were compared with laboratory-based measurements to determine validity.
RESULTS: The 5RFT showed a strong positive correlation with VO2max measured using the Bruce protocol (r = 0.675, p < 0.05). Additionally, a significant correlation was observed between the 5-minute oxygen consumption measured by K5 and the 5RFT (r = 0.621, p < 0.01). However, mean difference analysis indicated that the 5RFT estimation values were higher than both the K5 and Bruce protocol results (p < 0.001).
CONCLUSION: The findings suggest that the 5-minute running test, in combination with portable metabolic gas analysis, is a valid and practical method for estimating aerobic fitness in field settings. While the 5RFT may overestimate VO2max values compared to laboratory testing, its strong correlations support its applicability as a convenient alternative assessment tool.
