What\u2019s good for your heart is good for your brain. Just as physical activity helps keep our bodies fit and strong as we age, it also helps maintain our cognitive function \u2013 and is even linked with\u00a0lower dementia risk<\/a>.<\/p>\n

Yet beyond the longer term cognitive benefits of physical activity, exercise also seems to give a short-term boost to cognitive performance lasting from minutes to hours. According to our latest study, this cognitive boost may last up to 24-hours after exercising. Because some cognitive abilities start to decline as we get older, even small boosts to cognitive function can help keep us active and independent for longer.<\/p>\n

Studies conducted both in the lab and real-world settings have shown that people who are more physically active \u2013 whether that\u2019s in the form of\u00a0structured workouts<\/a>\u00a0or they just do more activity in their\u00a0day-to-day lives<\/a>\u00a0\u2013 perform better on cognitive tests in the hours after exercising.<\/p>\n

But one question researchers are still trying to answer is how long these cognitive benefits last \u2013 particularly in older adults, where maintaining cognitive function is very important. This is what our research aimed to do.<\/p>\n

In\u00a0our study<\/a>\u00a0of middle-aged and older adults, we found that people who did more moderate-to-vigorous physical activity (such as jogging or cycling) performed better on memory tests the following day. This suggests that the memory benefits of physical activity might last longer than the couple of hours found in previous,\u00a0lab-based studies<\/a>.<\/p>\n

Our study involved 76 participants aged 50-83. Each participant wore a wrist-worn activity tracker for eight days and nights. They were instructed to go about their daily lives as usual. From these activity trackers, we were able to see how much time participants spent being sedentary or physically active each day \u2013 and how intense this physical activity was.<\/p>\n

Because physical activity also\u00a0affects sleep quality<\/a>\u00a0\u2013 particularly the amount of time spent in the deepest and most restorative sleep phase, referred to as slow-wave sleep \u2013 we were also interested in exploring the role of sleep in cognitive performance. We extracted sleep quality characteristics from the activity trackers \u2013 including total sleep duration and time spent in slow-wave sleep.<\/p>\n

On each day the participants wore the activity trackers, they also took a set of cognitive tests. Some of these cognitive tests assessed episodic memory (being able to recollect previous experiences) and working memory (the ability to temporarily store information in the mind). The type of cognitive tests the participants were given alternated each day to reduce the chances of participants learning and remembering the answers.<\/p>\n

We wanted to be sure we had isolated the effect of physical activity and sleep on next-day cognitive performance. So, we took into account a number of demographic, socioeconomic and lifestyle characteristics that could have distorted the results. Each day, we also accounted for a participant\u2019s previous cognitive score to be sure we were focusing on day-to-day improvements in cognitive performance.<\/p>\n

Memory boost<\/strong><\/h4>\n

We found that the more time a participant spent doing moderate-to-vigorous physical activity, the better their episodic and working memory scores were the following day. Getting more sleep, particularly slow-wave sleep, was also associated with improvement in memory scores \u2013 independently of physical activity. But people who were more sedentary had worse working memory scores the following day.<\/p>\n

While the improvement in memory performance was relatively modest, none of our participants had cognitive impairment or dementia. So they realistically did not have much room to improve on these tests to begin with.<\/p>\n

But these results could serve as a jumping-off point for future studies examining next-day cognitive performance in people with neurodegenerative diseases \u2013 such as dementia, where we might see larger improvements in test scores. These findings also need replicating in a larger study before we can be sure of them.<\/p>\n

The short-term cognitive benefits of exercise are thought to occur because exercise stimulates blood flow and the release of specific brain chemicals that\u00a0contribute to cognitive function<\/a>. Generally, these neurochemical benefits are thought to last a couple hours following exercise. However, other changes induced by exercise \u2014 including some\u00a0implicated in memory function<\/a>\u00a0\u2014 might last for 24-48 hours following exercise. This might underlie the results we found in our study.<\/p>\n

Our findings point to the importance of maintaining active lifestyles as we age \u2013 and supporting this active lifestyle with good sleep.<\/p>\n
