High intensity exercise ward off dementia.
Jennifer J Heisz an associate professor in the department of kinesiology at McMaster University, I direct a team of researchers in the NeuroFit Lab, where we’ve shown that physical inactivity contributes to dementia risk as much as genetics.
Our latest research suggests that the intensity of the exercise matters. We enrolled sedentary seniors in a new exercise program and in just 12 weeks their memories improved. But this only happened for those who walked at a higher intensity, and their memory gains were directly related to their improvements in physical fitness.
It turns out that exercise does something that helps the brain regenerate itself: it grows new neurons in the hippocampus, and this improves memory.
The seniors participated in three sessions per week. Some performed high-intensity interval training (HIIT) or moderate-intensity continuous training (MICT) while a separate control group engaged in stretching only
The results are promising because they suggest it’s never too late to get the brain health benefits of being physically active, but if you are starting late and want to see results fast, our research suggests you may need to increase the intensity of your exercise
You can do this by including hills into your daily walk and picking up the pace between light posts. This will help keep dementia at bay to keep the ever-growing number of seniors healthier longer.
