We know that improvements in cardiovascular fitness are positively associated with the improvements in mental performance, and that a consistent program of exercise (with an emphasis on aerobic exercise) can help to maintain your physical and mental health over the long term.
While a specific prescription for exercise to boost brain health will require more research, there are still some important considerations for your current exercise regime.
Include rhythmic and continuous movement
The type of exercise featured in the research was defined as physical activity that was planned, structured and repetitive, with a focus on improving or maintaining fitness or health.
Choose activities that are rhythmic and continuous, and that increase your body’s demand for oxygen (aerobic) such as walking, cycling, running, swimming and rowing.
Vary your exercise routine
The intensity, frequency and length of exercise programs varied considerably across the 14 studies reported for influencing hippocampal volume.
So until further research is released, your best bet is to adopt a variety of training strategies.
High intensity interval training has recently been shown to produce similar cardiovascular benefits to long-duration endurance training in short periods of times. It would therefore be wise to include a combination of interval training and slow and steady cardio movements as part of your weekly training schedule.
Make it a habit
Brain health decreases with age, yet exercise may help to slow or even reverse the effects.
Exercise offers benefits throughout your lifespan, but you may have to make adjustment over time. For example, if you start to find running a bit tough on the joints, you can adopt lower impact exercises such as walking, cycling or swimming.
