This study determined the accuracy of non-exercise VO2max prediction equations with measured maximal oxygen uptake values in long distance runners. Eight male volunteer ULM cross country athletes performed a VO2max test and had their body composition measured utilizing the three site Jackson-Pollock skinfolds equation. The participants completed a modified version of the physical activity rating questionnaire to assess physical activity for the previous month. Activity levels included values for sedentary lifestyle (PA-R = 0) to running 60 miles per week (PA-R = 14). Non-parametric...
