A Couple Workouts Per Week May Lower Dementia Risk

Whether you are a weekend warrior or an everyday gym rat, incorporating exercise into your weekly routine invites a long list of health benefits. According to a recent study, one or two longer exercise sessions on the weekends may be as beneficial for brain health as working out more frequently throughout the week. 

For the study, the researchers looked at survey data collected from roughly 10,000 people in Mexico City. The participants began the survey when they were an average age of 51 and cognitively healthy. During the 16-year follow-up period, nearly 2,400 participants developed mild dementia. Compared to participants who did not exercise at all, the weekend warriors who logged one to two hours of exercise per week were 13% less likely to develop dementia. 

Moderate To Vigorous Exercise Has The Biggest Impact

Researchers noted that the total duration of physical activity matters more than the pattern for disease risk, which includes cognitive decline. Health experts advise that 150 minutes of moderate-to-vigorous physical activity per week is a good rule of thumb. Ideally, you sustain the same effort of moderate intensity throughout the entire workout. That means that you are able to complete sentences during the workout, but you may be just out of breath so that you do not have the effort to sing. 

The researchers did not look directly at exercise intensity or focus on the benefits of exercising for 150 minutes per week. Additionally, the study did not aim to prove whether weekend warrior workouts directly benefit brain health. With that information in mind, the study authors still concluded that middle-aged people could reduce their dementia risk by 13% by simply exercising at least once or twice per week. A total sedentary lifestyle increases the risk of health problems, including those related to cognition. 

Concentrated Exercise Promotes Brain Health

One limitation of this study was that it relied on the participants to accurately recall and report their exercise habits. The study authors did not objectively measure how often participants worked out, nor did they measure the intensity of workout sessions. It makes sense, though, that the weekend warrior workouts may contribute to long-term brain health. Additional benefits of weekend workouts include improving cardiovascular fitness, managing blood sugar, building lean muscle, and maintaining a healthy weight. 

Now, there are still some researchers who warn that the weekend warrior workout pattern may not prevent cognitive decline. Concentrated activity, however, had associations with lower risk of cognitive impairment that were just as beneficial as those observed with regular activity. More research is necessary on this topic, but this study shows promise and reaffirms the fact that exercise promotes a healthy brain and body.
