While sports over-the-top platforms have become the dominant medium for consuming live sports, the “hopping subscription” pattern—canceling after a season and rejoining later—poses a major challenge. This study examines the key motivations that shape subscription continuity. Drawing on a hybrid framework of uses and gratifications and the technology acceptance model, the research employs a mixed-methods design. Study 1 ( n = 104) employs explorat…
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
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
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 …
Association among length of residence, physical activity, and obesity in the US immigrants
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…
Objectively Measured Physical Activity Is Lower in Individuals with Normal Weight Obesity in the United States
The role of physical activity in normal weight obesity (NWO), which is associated with increased cardiometabolic risk, is not clear. This study aimed to determine body composition phenotype-specific differences in objectively measured physical activity and sedentary time in adults in the United States. A total of 2055 adults with a body mass index (BMI) ≥ 18.5 m 2 were studied using 2003-2006 National Health and Nutrition Examination Surveys. Phy…
Physical Activity Engagement outside of College Physical Education
Objective: In this study, we examined physical activity (PA) engagement outside of college physical education (PE) classes using the Transtheoretical Model (TTM). Methods: Overall, 414 university students enrolled in PE classes voluntarily participated in this study. Participants were asked to complete a survey packet to measure 4 core constructs of TTM and their PA level performed outside of PE classes. Among the participants, 150 randomly selec…
Patterns of Weight Change in a Commercial Weight Loss Program
Objectives: In this study, we examined compliance and progress factors associated with weight loss and maintenance, individual patterns of weight trends following weight loss, and impact of early weight loss on longer-term weight change. Methods: We conducted secondary analysis of pre-post data. Participants were 8769 persons (mean age = 47.63 ± 13.78 years; 77.74% women; mean weight = 97.20 ± 22.82 kilograms; BMI = 34.09 ± 6.84) in a commercial …
Temporal Trends in the Association between Participation in Physical Education and Physical Activity among U.S. High School Students, 2011–2017
The purpose of this study was to assess trends in physical education and physical activity among U.S. high school students from 2011 to 2017, respectively, and to evaluate temporal trends in the relationship between physical education class participation and physical activity levels. Data from a total of 51,616 high school students who participated in the Youth Risk Behavior Surveillance System (YRBSS) from 2011 to 2017 were analyzed for this stu…
Associations in physical activity and sedentary behaviour among the immigrant and non-immigrant US population
Background Immigrants are at a higher risk of poor mental and physical health. Regular participation in physical activity (PA) and low levels of sedentary time are beneficial for both these aspects of health. The aim was to investigate levels and trends in domain-specific PA and sedentary behaviour in the US. immigrant compared with non-immigrant populations. Methods From the 2007–2016 National Health and Nutrition Examination Survey (NHANES), a …
Sedentary behavior and metabolic syndrome in physically active adults
OBJECTIVES: The detrimental associations of sedentary behavior (SB) with metabolic syndrome have been shown to be independent of moderate-to-vigorous intensity physical activity (MVPA). Therefore, researchers, in addition to promoting MVPA, are calling attention to the need to reduce SB. However, there has been limited research on the association of SB with metabolic syndrome among those who already meet the PA guidelines. Therefore, the purpose …
Differential Use of Strategic Constructs of the Transtheoretical Model across Accelerometer-determined Sedentary Time
Objectives: In this study, we investigated the differences in strategic constructs of the Transtheoretical Model (TTM) across accelerometer-determined sedentary time. Methods: A total of 201 college students participated in a TTM questionnaire for sedentary behavior and wore an accelerometer for 7 consecutive days to assess sedentary time. Multivariate analyses of variances (MANOVA) with post hoc pairwise comparisons were conducted to determine m…
