The effects of acute exercise on memory: Considerations for exercise duration and participant body mass index
Acute moderate-intensity exercise has been demonstrated to improve memory performance. It is less clear, however, whether the duration of acute exercise and body mass index (BMI) may moderate this effect. Thus, the purpose of this experiment was to evaluate the effects of differing exercise durations (20- and 40-minutes) on immediate and long-term memory performance, while considering BMI as a moderating factor in this exercise duration and memor…
When and Why Do Sex Differences in Handgrip Strength Emerge? Age‐Varying Effects of Testosterone From Childhood to Older Adulthood
Objectives On average, males are stronger than females, with hormonal changes during puberty often cited as a contributing factor to this advantage. However, not all evidence consistently supports this explanation. The purpose of this study was to determine (1) when sex differences in handgrip strength and testosterone emerge, and (2) whether testosterone mediates the sex difference in handgrip strength and if this effect varies across age. Metho…
Age‐Varying Patterns of Total Cholesterol by Modifiable Lifestyle Factors Across Mid to Late Adulthood: Applying Time‐Varying Effect Modeling
Objectives Total cholesterol is a risk factor for cardiovascular disease, yet little is known about how its age‐related trajectory differs by lifestyle factors across adulthood. Methods We analyzed data from 8758 adults aged 40–80 years using NHANES from 2011 to 2020. Total cholesterol was measured via enzymatic analysis of serum samples. Physical activity was assessed using the Global Physical Activity Questionnaire, with participants classified…
Health Behaviors and Executive Function in Late Adulthood: A Time-Varying Effect Modeling Analysis
ObjectiveCognitive decline in older adults is a public health issue, with modifiable factors like obesity and sleep potentially influencing this trajectory. Previous research on their relationship with executive function has shown mixed results, particularly across older adulthood.MethodsThis study utilized time-varying effect modeling (TVEM) to assess the impact of body mass index (BMI) and sleep on executive function in older adults aged 60 to …
The association between physical activity and memory interference
Vigorous-intensity acute exercise during encoding can reduce levels of episodic and false memory
The potential benefits (veridical memory) and, importantly, costs (false memory) of acute exercise on memory in conjunction with the timing and type of exercise have not been fully studied. In Experiment 1, we employed a three-condition (15-minute vigorous-intensity acute exercise Before or During memory encoding, or a Control condition of watching a video), within-subjects, counterbalanced design. The procedures included an immediate and delayed…
Association among length of residence, physical activity, and obesity in the US immigrants: A regression‐based mediation analysis
OBJECTIVES: To examine the mediated relationship between objectively measured obesity, accelerometer-based moderate-to-vigorous physical activity (MVPA), and length of residence among US immigrants. METHODS: A total of 885 adults (≥18 years) who were born outside the United States from the 2003 to 2006 National Health and Nutrition Examination Survey were included in the analysis. The participants were categorized into two groups (i.e., living in…
A Validation Study of the Korean Version of the Nurses’ Patient Education Questionnaire
This study aimed to investigate the internal consistency reliability and construct validity of the Korean version of the Nurses' Patient Education Questionnaire. An accurate assessment of nurses' perceived patient education competency is required, and these needs assessment results can provide the evidence for designing a continuing education to empower and equip nurses with optimal competency for patient education. A cross-sectional study was us…
Acute Exercise and Sustained Attention on Memory Function
Objective: Sustained attention is critical for various activities of daily living, including engaging in health-enhancing behaviors and inhibition of health compromising behaviors. Sustained attention activates neural networks involved in episodic memory function, a critical cognition for healthy living. Acute exercise has been shown to activate these same neural networks. Thus, it is plausible that engaging in a sustained attention task and enga…
