Exercise Programming that Maximizes Brain Benefits
As young athletes develop, part of their growing skillset includes the ability to follow verbal instructions and make good decisions. This challenges kids to direct their attention and remain organized as they carry out goal-directed behaviors, using an ability known as executive function. Young athletes have an advantage in developing executive function because the brain regions that help us stay on task are highly sensitive to aerobic exercise. In fact, a child’s executive function is immediately improved by a single bout of physical activity.1-4 There is also a long-term cognitive improvement after regular exercise training,5-7 indicating that each season in which a child participates in regular practices may confer additive benefits to their executive function.
Why is executive function so important?
Part of every child’s potential for athletic success is based on their ability to focus, respond quickly, and adapt to new situations. While these skills certainly serve them on the field or court, it may come as no surprise that a child’s level of executive function predicts their success in school.8 Executive function develops slowly and matures during adolescence or early adulthood.9 This is why teams of older individuals can handle more complex tasks and follow directions more reliably.
Exercise primes the brain for improved executive function
The two major features that predict whether exercise will boost executive function are engagement and intensity.
Aerobic exercise that is highly engaging benefits executive function because more brain regions are activated, resulting in more blood flow to the brain. For instance, when teammates work together to complete a task, they show more activity in brain circuits important for listening and verbal communication. Practices that feature plenty of social interaction are a reliable way to keep athletes engaged and significantly improve their executive function.10 Beyond social interactions, higher brain activation also occurs when hand-eye coordination is challenged by complex tasks compared to simpler movements. Engaging forms of physical activity provide a longer lasting cognitive enhancement compared to repetitive and familiar types of exercise.11
Secondly, only moderate to vigorous exercise consistently improves brain blood flow and executive function.6 When this threshold of intensity is not reached, some studies failed to detect cognitive improvements, for example, treadmill walking in 7-11 year-olds,12 and stationary bicycling in 13-15 year-olds.13 For exercise to reliably improve brain function, it seems that the heart rate must be sufficiently increased. Intensity correlates to the athlete’s release of adrenaline (epinephrine), as well as the degree of neurochemical changes (in brain-derived neurotrophic factor) that optimize brain function.14,15 Selecting exercise intense enough for adrenaline release is also advantageous in terms of improving an athlete’s fitness and also closely matches the release of adrenaline that comes with competition during the athlete’s event or game.
Coaching for maximum benefits
As coaches, we are hopefully already structuring practices to include plenty of opportunities to cooperate and to adapt to new situations. These findings on brain benefits may convince you to introduce more variety to your warm-ups and conditioning exercises to ensure that your young athletes are reaping the full cognitive advantages.
