Physical activity and cognitive aging

We have developed and tested physical activity programs tailored to sedentary and frail older adults. We have shown for the first time (Langlois et al., 2013) equivalent benefits of 3 months of exercise training in frail and non-frail age-matched controls on cognitive and psychological outcomes. This complements our work on the effect of multiple types of physical exercise training on cognition in the elderly (Berryman et al., 2014; Predovan et al., 2013), as well as the benefits of multi-domain interventions combining exercise and cognitive training (Bherer et al., 2020, Desjardins-Crépeau et al., 2016). Contribution in this field is summarized in a review (Pothier & Bherer, 2016).  More recently, our team showed that physical exercise gains can vary between younger-old and older-old adults (Bherer et al., 2019).
