Introduction: Little is known about the impact of previous physical
activity on metabolic risks and continuous attention factors in the course of
aging. Furthermore, there is a discrepancy in the existing evidences due to
multi componential nature of these factors. Therefore, this study was conducted
to determine whether the previous physical activity history can synchronously
modify the changes in overall performance in sustained attention and total
metabolic risk in midlife and elderly men. Moreover, the modulating effects of
other individual variables on the impact of physical activity history on
aforementioned factors were investigated. Materials and Methods: 27 male subjects in midlife group including 13 active and
14 sedentary and 28 male subjects in elderly group including 15 active and 13
sedentary underwent Continuous Performance Test (CPT) and measurements of waist
circumference and blood pressure prior to fasting blood sampling. In order to
provide a quantitative index for performance in both continuous attention and
total metabolic risk groups, we calculated the overall CPT Z score (Zcpt) using
individual subject data at three components of CPT (Target Acc Rate, Foil Acc
Rate and Mean Reaction Time) and the total metabolic risk Z score (Zmets) of
five components of metabolic risk factors, including waist circumference,
arterial blood pressure and blood glucose, triglyceride and high density
lipoprotein levels. Results: There
was significant correlation between the age and number of metabolic risk
indices with continuous attention components (P
