Check out this week's findings in fitness, nutrition and sports science and see which ones are most relevant to your personal training clients. The one on the link between relieving mental fatigue by listening to music while running is a pretty intriguing one.
How childhood exercise could maintain and promote cognitive function in later life
Illuminating changes in brain networks and cortical structure
People who are physically active during childhood have higher cognitive functions in later life. Participants who exercised when they were children did better on cognitive tests regardless of their current age. However, no such relationship was found between task performance and post-childhood exercise -- suggesting that exercise during childhood is particularly important for brain development and long-term cognitive health.

Dieting and its effect on the gut microbiome
Bacterium associated with antibiotic-induced colitis plays a role in weight control
Researchers were able to show for the first time that a very low calorie diet significantly alters the composition of the microbiota present in the human gut. The researchers report that dieting results in an increase of specific bacteria - notably Clostridioides difficile, which is associated with antibiotic-induced diarrhea and colitis.

Starchy snacks may increase CVD risk; fruits and veggies at certain meals decreases risk
Eating fruits with lunch, vegetables at dinner and a dairy snack in the evening was associated with a reduced risk of early death by cardiovascular disease (CVD) and all-cause mortality, according to a study of U.S. adults. Eating a Western lunch (typically containing a high quantity of refined grains, cheese and cured meat) was associated with an elevated risk of CVD and all-cause mortalities in the same study.

Running to music combats mental fatigue, study suggests
Listening to music while running might be the key to improving people's performance when they feel mentally fatigued a study suggests. The performance of runners who listened to a self-selected playlist after completing a demanding thinking task was at the same level as when they were not mentally fatigued, the research found. The study is the first to investigate the effect of listening to music playlists on endurance running capacity and performance when mentally fatigued.
