ABSTRACT:
We compared the relationship between predicted VO2max (ml kg-1min-1) and recreational exercise patterns, using secondary data analysis of a comprehensive national survey (18,293 subjects aged 15-69 years). Exercise participation and predicted VO2max data were available for about 50 percent of this sample (4933 females, 4738 males). As expected, VO2max was significantly lower in the females than in the males at any age. Age was the most significant predictor of VO2max (r=0.71 for males, r=0.73 for females). Adjusting the data for the body mass index (BMI) increased this relationship only slightly in the males (R=0.75) and females (R=0.79). The simultaneous inclusion of exercise participation data (intensity, duration, energy expenditure) did not increase the predictions meaningfully (R=0.78) for the males, R=0.81 for the females). These exercise participation parameters concomitantly accounted for only a very slight amount of the variance of VO2max in both the females (3.0 percent) and males (4.5 percent). To minimize the effects of age, the data were analysed using 5-year intervals. Again, the exercise participation parameters accounted for only a small part of the variance in VO2max (less than 10 percent), except in the 15- to 19-year-old males (24 percent). These data suggest that VO2max is not associated with participation in recreational exercise.
