The aim of this research is to gain a better understanding of factors that relate to the increased health and effective functioning of older adults. Specifically, efficiency of psychomotor performance declines with advancing age leading to profound effects on older adults' quality of life. For this reason, researchers have focused on the influence that individual lifestyle habits have on the aging process. One lifestyle choice that has been found to positively contribute to the efficiency of older adults' psychomotor performance is cardiovascular exercise. This relationship appears to be especially significant when older adults are challenged with more complex or effortful tasks. Previous research has led investigators to believe that aging has a specific, rather than generalized, impact on cognitive functioning. Also, prolonged participation in cardiovascular exercise has been found to maintain the cognitive functioning critical for healthy aging.
