This investigation determined the effects of a 6-week resistance-training program on cognitive in previously untrained older adults (~70.5 years; N = 24). Ss were divided into two groups. The experimental group (N = 12) underwent full-body resistance training two days a week for six weeks. The control group (N = 12) continued their normal physical activity routines. Cognitive function was evaluated before and after the training period with two visuomotor reaction tests: i) average peripheral, visual, motor, and physical reaction times were recorded, and ii) a perceptual 3D-object tracking test where a threshold was determined.

No significant differences in cognitive function were evidenced between the groups.

Implication. Older adults who undergo six weeks of resistance training may experience improvements in aspects of cognitive function. However, such an effect was not demonstrated in this study. It is possible that the 12 training sessions over six weeks was insufficient for significant training effects to occur.
