dc.description.abstract While a great deal of research has been directed towards investigating the age-related decline in V02max, the effect of physical activity on the age-related decline in V02max has not been clearly established. Therefore, the purpose of this study was to examine the relationship between physical activity and the age-related decline in maximal oxygen consumption (VO2max) in apparently healthy individuals. In order to assess the effects of physical activity on the age-related decline in V02max, physiological data was obtained from 142 former participants (116 men and 26 women) (40 ± 8.0 years), in the Ball State University Adult Physical Fitness Program across an average of 12 ± 4.5 years. The subjects were divided into three physical activity group categories depending on their self-reported physical activity status at the time of the first and follow-up test. Those subjects who were sedentary at the first and last test were designated as SED-SED. Those who reported sedentary at the first test and active at the last test were designated as SEDACT and those who were physically active at the time of both tests were designated as ACT-ACT. The data from the analysis revealed that the rate of decline in V02mx expressed as change per year among adult men varied as a function of their reportedphysical activity habits. Those men designated as SED-SED and ACT-ACT experienced a statistically significant decline (p<0.05) in V02max during the follow-up period, while, those men designated as SED-ACT maintained their V°2max. The rates of the change in V02max (ml-kg- 1•min-1) for the men were -0.45, 0.03 and -0.22 ml•kg-l-min-1•yr1 for the SED-SED, SED-ACT and ACT-ACT groups respectively. The percent decline in V02max were 6%, 11% and 2% respectively. A statistical comparison of the rate of change among physical activity groups indicated a difference between the SED-SED and SED-ACT groups (p<0.05). Within the limitations of this study, these data suggested that there was no statistically significant difference in the rate of change in V02max (ml•kg-1•min-1-yr1) between the SED-SED and ACT-ACT physical activity groups. However, when presented as percent change per decade, the decline for those men who were sedentary at both time points was twice that of those men who reported an active lifestyle at both time points. Although the rates of change were not different for the SED-SED and ACT-ACT physical activity groups, those men with a physically active lifestyle maintained their aerobic power advantage as compared to sedentary men who remained sedentary. Furthermore, sedentary men who took up an active lifestyle had offset the decline in V02max (ml•kg-1•min-1) attributed to physical inactivity.The rates for the change in V02max (ml•kg-1•min-1-yr1) for the women were -0.36, 0.20 and -0.21 (ml•kg-1•min-1-yr1) for the SED-SED, SED-ACT and ACT-ACT groups respectively. While these changes were similar in direction and magnitude to those observed for the men, there were no statistically significant differences among the female groups (p>0.05). Therefore the results from the present study were inconclusive for women possibly due to the low sample size (n=26).
