Exercise improves your mood by prompting the release of feel-good endorphins. Moving your body also strengthens your muscles and enhances your ability to perform your everyday functional tasks. Exercising provides an abundance of benefits for your mind and body, including improving cognition. For example, a large study of Swedish military recruits revealed that as people grow physically stronger, they also become a little smarter. If you’re wondering which type of exercise boosts brain power and how long to do it, a recent review of over 100 studies yielded an interesting conclusion.

The review

Researchers at the University of California, Santa Barbara, assessed over 100 studies to determine whether individual exercise sessions affect the brain, and which type of exercise had the biggest impact. The studies examined more than 4,000 healthy adult participants, and the review was published in Communications Psychology.

The results

Neuroscientist and senior author of the study, Barry Giesbrecht, explained that exercise interventions, such as a program you would do three times a week over several months or years, improve cognition. The researchers concluded that just one short burst of exercise can enhance your thinking skills, and exercise lasting less than 30 minutes was more effective than exercise lasting longer than 30 minutes. 

The most optimal types of exercise are vigorous heart-pumping workouts like cycling or high-intensity interval training. The researchers showed that these types of exercise were associated with the most significant positive changes in cognitive abilities and executive functioning, which involves working memory, planning, attention, information processing, and multitasking. 

The takeaway

The takeaway here is that even one single session of exercise for 30 minutes or less can brush up your thinking skills and could help you to be more productive for the rest of your day. Even if you can only fit in one or two workouts that week, it’s still worth it for your brain and body. You might accomplish more at work if you boost your mood and cognition with the power of exercise. The researchers of this large review showed that vigorous and aerobic exercise like HIIT provides the best outcome.

Exercise in general has been proven beneficial for your heart health, from reducing the risk of cardiovascular disease to lowering blood pressure and inflammation. You don’t have to spend hours exhausting yourself at the gym or running marathons to see these heart benefits.

Previous research shows that walking at an average pace of around three to four miles per hour lowered the likelihood of a heart arrhythmia by one-third and resulted in a 35% reduced risk of heart rhythm abnormalities. Walking at a pace faster than four miles per hour slashed that risk by 43% as well as lowering the levels of inflammation. Taking a brisk walk around the block is also advantageous for your heart.

The beet boost: Here’s what science says about drinking beet juice pre-workout
Gulping down just a few ounces of this colorful juice before your workout could combat fatigue, enhance endurance and muscle power, and more.

I’ve always liked beets, from the sweet yet slightly zesty flavor to the array of vibrant colors. You can find colors like deep royal purple, red, golden yellow, and white beets. Betanin is the natural pigment that’s responsible for the red color of beets. This pigment has strong antioxidant properties.

One of my favorite healthy nutritional approaches to help manage autoimmune disease is the Wahls Protocol, created by Dr. Terry Wahls to tackle her own multiple sclerosis. As Dr. Wahls says, “eat the rainbow”, and she doesn’t mean Skittles; she means bright, colorful fruits and veggies, like beets. These deeply pigmented, colorful foods are anti-inflammatory, rich in antioxidants, and provide numerous health benefits, including helping to protect against chronic diseases like heart disease.
