It has been proven that exercise improves brain function, but two new studies ask whether or not these improvements are long lasting. Lorna Kleidman, a kettlebell trainer, offers her thoughts on the subject.

On January 14, Lorna Kleidman responds to two recent studies aimed at finding out if improved brain functionality due to exercise is a long lasting effect, or if it wears off after we stop working out regularly, as reported by the New York Times.

Lorna Kleidman, a fitness expert and trainer of kettlebell exercises, has always encouraged people to exercise regularly. While it has already been proven that our brains improve on a structural and functional level after a few months of regular exercise, two new studies were recently conducted to determine if these improvements are permanent or if they wear off after a period of remaining sedentary.

According to a recent article from the New York Times on the studies, “the more dramatic [of the two experiments] looked at what happens to the brain’s memory center when exercise is stopped.” This study measured the creation of brain neurons linked to the memory of rats while they consistently ran on exercise wheels for a week. The article states that the wheels were then locked, so that the rats remained sedentary for several weeks. The study found that after several weeks of not exercising, the rats’ memories faded.

The second study concerned mood in relation to exercise. According to the article, the study was very similar to the first however the researchers measured enzymes related to mood in the rats. When comparing the rats that exercised then stopped to a control group that had not run on the exercise wheels at all, the study found that the two groups “had almost comparable levels of an enzyme in the brain that affects the synthesis and uptake of serotonin. It was as if they had never run.”

After reading about the studies, Kleidman said that she was surprised by how quickly the rats reverted back to their normal, sedentary brain function. “I’ve always told people that they have to keep up with their exercise routines, not just lose ten pounds then call it quits,” she said. “The studies should be more of an incentive for people to continue to work out regularly.”

Kleidman added that while setting goals is great for exercising, you should never stop after reaching your goal. “You have to continue to work to maintain a good fitness level,” says Kleidman.
