Key Takeaway
Consider aerobic exercise as a promising nonpharmacological therapy to improve executive function in adults with MDD.

This systematic review and three-level meta-analysis assessed the impact of aerobic exercise on executive function in adults with major depressive disorder. The review synthesized data from studies where interventions were conducted three times weekly at moderate and vigorous intensities, lasting 45 minutes per session and 90 to 149 minutes weekly over 3 to 10 weeks or longer. The follow-up period averaged 2.3 months.

Results indicated that overall core executive function improved significantly with a standardized mean difference of g = 0.14 and a 95% CI of 0.05 to 0.22. Inhibitory control improved significantly with a g of 0.19, and cognitive flexibility improved with a g of 0.17. Working memory showed a g of 0.08 but did not achieve statistical significance.

The authors note that adverse events, serious adverse events, discontinuations, and tolerability were not reported in the source data. Funding or conflicts of interest were also not reported. The authors conclude that aerobic exercise is a promising nonpharmacological therapy to improve overall core executive function and its subdomains of inhibitory control and cognitive flexibility in this population.

Major depression often clouds the mind, making it hard to focus, switch tasks, or remember details. A new analysis looked at whether regular movement could help clear that mental fog. The team examined data from 780 adults who participated in aerobic exercise programs. These workouts happened three times a week for at least three weeks, lasting between 45 minutes and two hours each time. Participants did moderate or vigorous activity like brisk walking or jogging. The goal was to see if this physical effort could boost how well their brains worked on daily tasks.

The results were encouraging for specific mental skills. Adults who exercised showed statistically significant improvements in their ability to control impulses and switch between different thoughts. They also became more flexible in how they approached problems. These changes happened after just a few weeks of consistent activity. The study tracked these benefits for about two and a half months after the exercise programs ended.

One area did not show a significant change: working memory. This is the ability to hold information in mind while using it. While the overall thinking skills improved, the data did not confirm a boost in this specific memory function. No serious safety problems or side effects were reported during the programs. This suggests that moving your body is a safe way to support brain health for people dealing with depression.

What this means for you:
Regular aerobic exercise improves focus and mental flexibility in adults with major depression.

This study aimed to investigate the effects of aerobic exercise (AE) on overall core executive function (EF) and its subdomains in adults with major depressive disorder (MDD). We systematically searched Embase, Ovid MEDLINE, Web of Science, Scopus, and PubMed up to October 12, 2024. We included randomized controlled trials (RCTs) that investigated the effects of AE on core EF in adults with MDD. We conducted a three-level meta-analysis with a random-effects model in R and used the Physiotherapy Evidence Database scale to assess study quality. Ten RCTs involving 780 depressed adults were included. AE statistically significantly improved overall core EF (g = 0.14; 95% confidence intervals [CI] = 0.05, 0.22; p = 0.004) and its subdomains of inhibitory control (g = 0.19; 95% CI = 0.07, 0.32; p = 0.004) and cognitive flexibility (g = 0.17; 95% CI = 0.01, 0.33; p = 0.043), but not working memory (g = 0.08; 95% CI = -0.01, 0.17; p = 0.070) in adults with MDD. Aerobic exercise, conducted three times weekly at moderate and vigorous intensities (45 min per session, 90-149 min weekly) and over 3-10 weeks or longer, can improve the overall core EF in adults with MDD. This study found that AE is a promising nonpharmacological therapy to improve the overall core EF and its subdomains of inhibitory control and cognitive flexibility in adults with MDD. AE plus antidepressants and the percentage of females were significant moderators.
