The Whole Day Movement Matters to Executive Function Among College Students.

Area of Science:

• Behavioral science
• Cognitive neuroscience
• Public health

Background:

• Executive function and movement behaviors are often studied in isolation.
• Understanding the combined impact of physical activity, sedentary behavior, and sleep on executive function is crucial for college students' well-being.

Purpose of the Study:

• To investigate the combined associations of various movement behaviors (MVPA, light PA, screen-based SB, non-screen-based SB, sleep) with executive function (working memory, inhibition).
• To explore the relationship between body mass index (BMI) and executive function, specifically inhibition, in young adults.

Main Methods:

• Utilized validated questionnaires to assess movement behaviors and executive function in 366 college students.
• Employed regression analyses to determine the predictive power of movement behaviors and BMI on executive function components.

Main Results:

• Screen-based sedentary behavior (SB), sleep duration, and moderate-to-vigorous physical activity (MVPA) significantly predicted working memory.
• Body mass index (BMI) was the sole significant predictor of inhibition.
• Overweight/obese students exhibited poorer inhibition compared to healthy-weight peers.

Conclusions:

• Promoting healthy movement patterns, including sufficient MVPA, reduced screen-based SB, and adequate sleep, can enhance working memory in college students.
• Weight management is important for maintaining inhibitory control, a key aspect of executive function.
