There is abundant evidence that aging makes elderly people weaker, slower, less powerful and also causes a deterioration in their balance and reaction time [1-3]. Nevertheless, it is still difficult to make a clear distinction between the effects of aging, deconditioning and disease with respect to decreased performance and health status. Since, most of the aging studies have cross-sectional designs and therefore, are prone to confounding, they cannot give a clear answer about true effects of aging. Previous investigations have demonstrated that some components of physical fitness in elders can be improved by physical activity (PA) [4-6].
