Among the changes associated with aging there is a cognitive decline. However, a healthy life style, such as physical exercise seems to generate a protective effect against this cognitive decline. The literature has shown that both aerobic and the resistance exercise, when practiced in isolation seem to result in benefits to cognition. Yet it is not described if the combination of both methods would result in the same benefit. The aim of this study was to investigate the effects of combined training on cognitive function in health elderly. Were select thirty-three elderly subjects who were randomly divided into two groups: Control (N = 17) and Combined (N = 16). The control group was instructed to maintain their usual activities and the combined group participated in a training program composed by aerobic and resistance exercise, three times per week on alternate days for a period of six months. Both groups underwent a physical assessment (spirometry and testing of 1 Repetition Maximum - 1RM), cognitive (through neurophysiological and neuropsychological measures), mood, quality of life and blood tests (Insulin-like growth factors type 1- IGF-1 - and blood viscosity) at the beginning and the end of the protocol. The results showed that in the physical assessments, both oxygen consumption (p = 0.01) and 1RM (p = 0.001), the experimental group after training showed a significant difference when compared to the control group. The variables relating to body composition also showed significant differences after the intervention, causing a decrease in fat mass (p = 0.016) and an increase in fat-free mass (p = 0.016). Moreover, the same type of comparison, the combined group, after a period of six months, performed better in the following tests: Rey Complex Figure and Taylor (p = 0.01); Toulouse, which obtained a percentile in the quality (p = 0.045); Similarities (p = 0.003); and Sum of all the attempts to test Verbal Associated Pairs (p = 0.043). There were no statistical differences in the other analysis. Thus, the conclusion is that the combined training can increase both strength and aerobic capacity in healthy elderlies, affecting an improvement in the ability of abstraction, inhibitory control, short-term memory and learning regardless of serum IGF-1 and blood viscosity.
