Physical Activity, Sedentary Behavior, and Their Predictors Among Nursing Home Residents-Cross-Sectional Results of the BaSAlt Study.

Little is known about physical activity (PA) and sedentary behavior (SB) among nursing home residents although PA is known as a health promoter. This study examined PA, SB, and their predictors among nursing home residents (n = 63). Dependent variables were accelerometry-based PA and SB. Predictor variables included in a path analysis were age, sex, body mass index, Barthel Index, cognitive status (Mini-Mental State Examination), physical performance (hand grip strength and habitual walking speed), and well-being (World Health Organization-5 well-being index). PA was very low (M steps per day = 2,433) and SB was high (M percentage of sedentary time = 89.4%). PA was significantly predicted by age (β = -0.27, p = .008), body mass index (β = -0.29, p = .002), Barthel Index (β = 0.24, p = .040), and hand grip strength (β = 0.30, p = .048). SB was significantly predicted by body mass index (β = 0.27, p = .008) and Barthel Index (β = -0.30, p = .012). Results might be helpful for everyday practice to identify individuals at high risk for low PA and high SB.

Leisure time activities of children: Inequalities, determinants, and inter-relations

More studies should adopt a combined approach to modifiable lifestyle behaviors because of their potential synergistic effects on health. This study aims to observe how boys and girls allocate their time on different activities, during week and weekend days, investigate the time inter-relations between different leisure activities, and analyze how child and familial characteristics are associated with children’s time use in multiple activities. In 2016/17, a validated questionnaire collected data from 3-10-year-old Portuguese children (n = 8,472). Parents reported their children’s time use in different behaviors: sleep, study, screen media use, indoor and outdoor play, and school commute, as well as children’s participation in sports, and socio-economic characteristics of the family. A combination of statistical analysis (e.g., t-tests, pairwise correlations and multiple linear regression) revealed that: boys reportedly have higher screen time than girls, but they also accumulate more time in outdoor play; the time spent in different activities was determined by a set of family sociodemographic factors, such as urbanization and parental employment; and exists some inter-relation between leisure activities with high screen time being significantly associated with less sport participation and less sleep duration. Identifying time spent in multiple activities that differ by sex (and associated determinants) is critical for the development of activity promotion strategies, and may help to inform evidence-based policies designed to increase physical activity and decrease sedentary behavior in young children. Present findings highlight the growing importance of electronic media in children’s life and how they can displace other leisure activities.

Linking social determinants of health to mental health, movement behaviors, and cognitive function among U.S. youth

BackgroundFew studies have focused on a comprehensive view of social determinants of health (SDOH) domains as influences on the health of young people. This study aimed to investigate the associations between the Healthy people 2030 SDOH-related domains (i.e., economic stability, education access and quality, health care access and quality, neighborhood and built environment, and social and community context) with mental health, movement behaviors, and cognitive function among U.S. youth. MethodsThis cross-sectional study used nationally representative data from the 2020–2021 National Survey of Children's Health, covering 54,595 youth aged 6–17 years. The associations of indicators of SDOH-related domains with mental health (depression and anxiety), movement behaviors (physical activity and screen-based sedentary behavior), and cognitive function were estimated using multivariable logistic regression models, adjusting for age, sex, and race. ResultsEconomic stability, education access and quality, health care access and quality, and social and community context were associated with at least one outcome measure of mental health, movement behaviors, and cognitive function, while neighborhood and built environment was associated with mental health and movement behaviors. The social and community context domain stood out, with friendship difficulty and household-based adverse childhood experiences being associated with poorer outcomes on most health indicators. ConclusionAll five SDOH-related domains are related to aspects of youth health, with the social and community context domain showing the most associations, highlighting the need for interventions to improve social connection and address adverse childhood experiences, which may be more impactful in ameliorating many health-related challenges.

Move more today, sleep better tonight? Daily associations between physical activity and sedentary behavior with sleep among young adults with and without insomnia symptoms

ObjectiveAt the between-person level, it is well-documented that individuals with more physical activity (PA) and less sedentary behavior (SB) tend to have better sleep outcomes than their peers. However, the associations at the within-person level remain unclear. This study investigated the daily associations between PA and SB with nighttime sleep among young adults with and without insomnia symptoms. MethodsData was collected through activity trackers and online questionnaires for 7 consecutive days among 147 university students, including time spent on moderate to vigorous physical activity (MVPA), light physical activity (LPA), and SB, along with sleep duration, sleep efficiency, and sleep quality. Participants were classified into two subgroups according to the presence of insomnia symptoms, which were determined by a self-reported insomnia scale. Multilevel compositional data analysis was conducted on the total sample, and separately on subsamples characterized by the presence and absence of insomnia symptoms. ResultsIn the total sample and subsample without insomnia symptoms, substitutions among MVPA, LPA, and SB were not associated with changes in sleep outcomes at the daily level. However, in the subsample with insomnia symptoms, days with more MVPA or SB and less LPA were associated with higher sleep efficiency, while days with more LPA at the expense of MVPA or SB were associated with lower sleep efficiency. ConclusionsFor young adults with insomnia symptoms, replacing LPA with MVPA on a given day may improve their sleep efficiency that night.

Genetically-predicted effects of lifestyle factors on frailty: Evidence from Mendelian randomization study

ObjectiveTo evaluate the causal relationships between genetically predicted lifestyle factors and frailty using Mendelian randomization(MR). MethodsWe extracted summary data from genome-wide association studies conducted among individuals of European ancestry, examining lifestyle factors such as smoking, alcohol consumption, physical activity, and sedentary behaviors. The outcomes were assessed using Fried Frailty Score (FFS) and Frailty Index (FI). We conducted 2-sample single-variable Mendelian randomization (SVMR) and multivariable Mendelian randomization (MVMR) to simultaneously assess the independent causal effects were primarily estimated using inverse variance weighted methods. Multiple sensitivity and validation analyzes were used. ResultsThe IVW analyzes indicated that smoking increased frailty risk (FFS: β = 0.107, 95 % CI = 0.057 to 0.156, P < 0.001; FI: β = 0.899, 95 % CI = 0.016 to 0.191, P = 0.020.), this effect was amplified in the MVMR analysis after adjusting for alcohol consumption. Strenuous sports or other exercise(SSOE) reduced frailty risk (FFS: β = -0.473, 95 % CI = -0.646 to -0.299, P < 0.001; FI: β = -0.423, 95 % CI = -0.692 to -0.154, P = 0.002). Vigorous and moderate-to-vigorous physical activities were significantly related to lower FFS, although no effects were observed on FI. Increased television watching was linked to higher frailty incidence (FFS: β = 0.227, 95 % CI = 0.197 to 0.257, P < 0.001; FI: β = 0.297, 95 % CI = 0.249 to 0.346, P < 0.001), the impact remained persistent in MVMR adjusting for driving and computer use. ConclusionThis study suggests that modifications in smoking, alcohol consumption, and physical activity may help prevent or manage frailty.

Tracking Well-Being: A Comprehensive Analysis of Physical Activity and Mental Health in College Students Across COVID-19 Phases Using Ecological Momentary Assessment.

Physical activity (PA) is a critical factor in maintaining mental health, particularly among college students who are vulnerable to stress, anxiety, and mood disturbances. The COVID-19 pandemic introduced unprecedented disruptions to daily routines. The purpose of this cohort study was to examine the longitudinal PA behaviors before and during COVID-19 using device-based assessment in a sample of college students. The participants were a convenience sample of 1-year college students from the University of Vermont Wellness Environment study. A daily survey was distributed to the participants every night on a study app measured three mental health outcomes of mood, anxiety, and stress for 16 weeks. Participants wore Apple Watches to monitor PA. A total of 167 participants completed at least 50% of daily surveys and had 20 days of valid Apple Watch data, which resulted in 11 387 participant-days' of observations. Changes in average daily moderate-to-vigorous physical activity (MVPA) and step counts were examined week-over-week from an 8-week period before COVID to an 8-week period during COVID using cluster-robust piecewise regression (16-weeks total). Linear mixed models examined the association between PA and mental health outcomes, while also examining the moderating influence of COVID phase. Significantly lower MVPA was observed from the end of pre-COVID to start of COVID by -18.2 min/day (p < 0.001) and significantly fewer steps/day was observed from end of pre-COVID to start of COVID by -3277 steps/day (p < 0.001). An MVPA "catch-up" effect was observed as there were small but positive week-over-week improvements during COVID for MVPA (b = 1.32 min/day, p < 0.001). The influence of COVID-19 phases had a notable impact on the relationships between PA/exercise and mental health outcomes. A discernible trend emerged, indicating stronger connections during the COVID period for anxiety and stress compared to the pre-COVID era. Interestingly, the moderating effect of COVID was opposite for mood and exercise. The COVID-19 pandemic led to a dramatic decline in PA among college students, coinciding with a period of heightened stress and anxiety. Despite a slight recovery in PA levels during the pandemic, the strengthened association between exercise and anxiety/stress during this time underscores the vital role of PA in promoting mental health. These findings highlight the importance of implementing behavior change strategies to maintain and promote student wellbeing.

Determination of Salivary Cortisol Levels and Nutrition, Smoking and Physical Activity Status of University Students during the Exam Period

Objective: The aim of this study is to determine the salivary cortisol levels and nutrition, smoking and physical activity status of university students during the exam period. Method: This study was conducted at Bayburt University Faculty of Health Sciences during the 2023-2024 final exam period. A questionnaire determined the demographic characteristics, dietary and physical activity behaviors, while anthropometric measurements were taken and nutritional status was evaluated. ELISA analyzed the cortisol hormone levels in saliva samples taken before and after the final exam. Results: The study was conducted on 120 volunteer students between the ages of 18-25 who had no clinical health problems. In the study, a significant difference was found between the students' salivary cortisol levels before and after the exam (p

Personality and health behavior changes after pulmonary rehabilitation: A longitudinal observational study.

Pulmonary rehabilitation (PR) is the gold standard treatment for improving the health status of individuals with chronic respiratory diseases (CRD). However, to achieve lasting results, the adoption and maintenance of a physically active lifestyle are necessary. Unfortunately, the trajectories of change in physical activity (PA) and sedentary behavior (SB) following PR are marked by a high degree of heterogeneity between patients. This study aimed to better understand the factors underlying this variability by investigating the role played by the personality as defined by the five-factor model. Eighty eight CRD patients were assessed on personality upon PR admission (Time 1). PA and SB were assessed at Time 1 and 6 months post-PR (Time 2) using questionnaires. Multiple regression analyses revealed that "healthy neuroticism" is associated with an increase in PA 6 months after PR (β = .20, p < .05) independently of the PA at Time 1. A high level of neuroticism, when it is paired with a low level of conscientiousness, is related to an increase in SB 6 months after PR (β = -.20, p < .01), when the SB and exercise tolerance at Time 1 were controlled for. These findings highlight that investigating the interaction between personality traits is relevant to a better understanding of the interindividual differences in changes in PA and SB after PR in patients with CRD. The behavioral effects of PR could be improved if patients' personality traits were taken into account in the design of behavior-change interventions.

The Effect of Physical Education with a Humanistic Approach on the Physical Activity Level and Physical Fitness in Shy Children

Background: Shy children often avoid interacting with their peers, which can restrict their participation in physical activities and impact their physical fitness. Therefore, it is essential to offer specific support and strategies to assist these children in increasing their involvement and enhancing their physical fitness. Objectives: This study aimed to investigate how physical education, utilizing a humanistic approach, impacts the physical fitness and daily physical activity behavior of shy children. Methods: In order to achieve this, a quasi-experimental field study was planned with pre- and post-tests including a control group. Participants were 9 to 10-year-old elementary school girls from Tehran, selected based on the Chick-Briggs Shyness Scale Physical fitness was measured using tests for cardiorespiratory endurance, agility, muscular endurance, muscular strength, and flexibility. The physical Activity Questionnaire for Children (PAQ-C) was utilized in assessing children's attitude towards physical activity. The experimental group (n = 15) received a physical education course with a humanistic approach using the teaching physical and social responsibility (TPSR) model, while the control group (n = 15) maintained their usual daily routines. Results: The experimental group showed significant improvements in physical activity levels, muscular endurance, and flexibility compared to the control group. A humanistic, game-based educational approach using the TPSR model can effectively improve certain components of physical fitness and promote a positive attitude towards physical activity in shy children. Conclusions: This approach can help teachers and coaches better understand and assist this group of children in overcoming the negative relationship between shyness, sports participation, and physical fitness.

Perceptions of Behaviour Change Interventions for Physical Activity in People with Chronic Obstructive Pulmonary Disease: A Survey

Abstract Background Physical inactivity in chronic obstructive pulmonary disease (COPD) is common and behaviour change interventions could help improve physical activity (PA). This survey aimed to explore perceptions of behaviour change interventions for physical activity in people with COPD. Methods An anonymous cross-sectional electronic and paper survey was distributed among people with COPD in the Republic of Ireland (n=150) via relevant gatekeepers. Descriptive statistics, means, medians, percentages and frequencies, were used to summarise and describe the findings. Chi- squared t-tests (where P was set at 0.05) were used to investigate relationships between variables. Results Responses were received from n=113 people with COPD (75.33% response rate, 113/150) and most respondents (83.03%, n= 93/112) were aged over 61 years. 90.53% (n=86/95) of respondents agreed/strongly agreed that PA helps them to manage their COPD. There was a strong statistically significant relationship between those who wear PA monitoring devices and those who believe that being physically active can help them to manage their lung disease (p&amp;lt;0.001), however, in this survey, the use of PA monitors in those over 61 years was proportionally lower (21.11%, n=19/90) than those under 60 years (61.53%, n= 8/13). Respondents perceived social support as the most effective behaviour change intervention to influence PA behaviour (67.62%, n= 71/105), with counselling for PA perceived to be the least effective (13.33%, n=14/105). Conclusion People with COPD perceived that social support can influence their PA behaviour. The spontaneous use of PA monitoring devices was lower in older respondents than in younger respondents, however a strong relationship between using monitoring devices and perceived benefits of PA on COPD may exist overall.

Physical activity through place attachment: Understanding perceptions of children and adolescents on urban places by using photovoice and walking interviews

Public urban places and their environmental characteristics impact youth's physical activity (PA) through perceptions. The objective of this study was to use a qualitative participatory approach with children and adolescents to understand how their attachment to urban places perceived as PA-friendly or unfriendly is related to their PA behaviour. Ninety-three participants aged six to 17 from six neighbourhoods with varying objective walkability engaged in photovoice and walking interviews. Data were analysed by using the tripartite framework of place attachment (PPP model), which was adapted for application to PA behaviour and supplemented by photographs. Themes were identified for each (sub-)dimension of the PPP model with person, place and process factors influencing attachment. Further subdimensions (PA and other behaviours) and categories (travel mode, trip length and frequency of visits) were added to the PPP model. Urban design recommendations were derived by age and gender to promote PA through place attachment.

Role of physical activity and sedentary behavior in venous thromboembolism: a systematic review and dose-response meta-analysis

Increasing studies have investigated the link between physical activity (PA) and sedentary behavior with venous thromboembolism (VTE) but the existing findings are not consistent and the independent relationship is uncertain. This meta-analysis aimed to comprehensively assess the shape of dose-response relationship between PA and sedentary behavior with VTE and further explore whether the relationship is independent after mutual adjustment. We systematically searched PubMed, Embase and Web of Science from inception to August 1, 2024. PA exposures were converted into MET-h/wk. Categorical meta-analyses and a cubic spline model were performed to evaluate the association between PA, sedentary behavior and VTE. Twenty-five articles including 31 studies were included. A curvilinear dose-response relationship between PA and VTE was observed, with steeper gradients even at lower PA levels. After adjustment for sedentary behavior, higher level of PA was independently associated with a reduced VTE risk (OR = 0.83, 95%CI:0.77–0.89). Based on population attributable fraction analyses, 2.37% (95%CI: 1.90-2.85%) of incident VTE could have been prevented if all adults had achieved half the PA minimum recommended level. A linear dose-response relationship between sedentary behavior and VTE risk was found, and there was a 2% higher risk of VTE (OR = 1.02, 95%CI: 1.00-1.03) for 1 h increment of sedentary behavior per day. After adjustment for PA, sedentary behavior was independently associated with an increased VTE risk (OR = 1.19, 95CI%:1.01–1.39). Our analyses demonstrated PA and sedentary time were indeed independently associated with the risk of VTE after mutually adjusting for sedentary time or PA, highlighting a unique perspective on their individual contributions. Further studies assessing the effects of different combinations of PA and sedentary time for assessing joint effects on VTE are needed.

Thyroid function, physical activity and sedentary behaviour: A bidirectional two-sample Mendelian randomisation study.

The interinfluence of thyroid function and daily physical activity (PA) remains unclear. We examined the causal relationship between genetically proxied thyroid-related traits; hypothyroidism, hyperthyroidism, thyroid stimulating hormone (TSH) and free thyroxine (FT4), and daily PA measures; leisure screen time (LST) and moderate-to-vigorous physical activity (MVPA), using Mendelian randomisation (MR) analysis. We used genome-wide association study (GWAS) data from the ThyroidOmics Consortium and the most comprehensive meta-analysis on PA, comprising data on hypothyroidism (n = 53 423), hyperthyroidism (n = 51 823), TSH within the reference range (n = 54 288), fT4 within the reference range (n = 49 269), LST (n = 526 725), and MVPA (n = 608 595) to conduct a bidirectional two-sample MR analysis. The inverse variance weighted (IVW) method was employed as the primary result. Sensitivity analyses included MR-Egger, weighted median, and MR pleiotropy residual sum and outlier (MR-PRESSO) regression. Similar investigations were conducted in the reverse direction. Finally, we analysed a multivariable MR using body mass index (BMI)-related traits GWAS data. In the primary IVW analysis, an increase in genetically proxied TSH levels significantly increased LST (correlation coefficient (β) = 0.040; 95% confidence interval (CI) = 0.020-0.061, P = 9.776 × 10-5). The multivariable MR analysis indicated that the positive causal effect still existed when considering the influence of BMI (MVMR-IVW: β = 0.042; 95% CI = 0.011-0.073, P = 0.007). Conversely, there was no evidence to suggest that PA impacts thyroid function. The results of this MR analysis suggest that thyroid function influences daily PA. The positive association between TSH and LST is not confounded or mediated by BMI.

Mind the intention-behavior gap: a qualitative study of post-myocardial infarction patients’ beliefs and experiences with long-term supervised and self-monitored physical exercise

BackgroundMany post-myocardial infarction (MI) patients struggle with physical activity behavior change (BC) for life-long secondary prevention. There is limited knowledge about factors influencing long-term physical activity BC among post-MI patients. This qualitative study aimed to explore the beliefs and experiences related to post-MI patients’ physical activity BC process following a year’s participation in a supervised and self-monitored exercise program: the Norwegian Trial of Physical Exercise After MI (NorEx).MethodsWe conducted a qualitative study, performing in-depth semi-structured interviews with a randomly selected sample of NorEx participants when they were scheduled for cardiopulmonary exercise testing after one year of participation. Interviews were transcribed verbatim and the data was analyzed by applying reflexive thematic analysis.ResultsSeventeen participants (n = 4 female [24%]; median age, 61 years; median time since index MI, 4 years) were recruited and interviewed once. Analysis resulted in four main themes (nine sub-themes): (1) Personal responsibility to exercise (Exercise is safe, Health benefits, Habitual exercise); (2) Peer social support for a sense of safety and belonging (Social exercise, Supervision is preferred); (3) Research participation transformed exercise beliefs (High-intensity exercise is superior, Personal Activity Intelligence (PAI) promotes exercise adherence); and (4) Mind the intention-behavior gap (Initial anxiety, Lack of continued follow-up).ConclusionsSeveral participants reported that they were able to maintain exercise BC during a year’s participation in NorEx. Nevertheless, a perceived lack of continued and individualized follow-up made some participants struggle with motivation and self-regulation, leading to an intention-behavior gap. Therefore, our findings suggest there is a need for individualized and continued social support and supervision from health and exercise professionals to maintain long-term exercise BC for secondary prevention among post-MI patients.Trial registrationThe NorEx study has been registered at ClinicalTrials.gov (NCT04617639, registration date 2020-10-21).

The momentary relationship between physical activity behaviour and mental well-being of vocational education and training students

Background and aimsVocational education and training (VET)-students often face student mental well-being (SMW) challenges. Physical activity behaviour (PAB) is positively associated with SWM, yet SMW can vary during the day. Therefore, this study aims to explore the momentary relationship between PAB ((i.e., moderate to vigorous physical activity (MVPA), light physical activity (LPA), sedentary behaviour (SB)) and SMW (i.e., affect, self-esteem). MethodsFor 9 consecutive days, VET-students reported their SMW via experience sampling methods-prompts while their PAB was measured with thigh worn ActivPALs™. PAB data was summed in minutes spent in each PAB 30 and 60 minutes before each prompt. Data of 68 students (68% female, mean-age=18.9±4) was analysed with multilevel regression analyses. ResultsConsistently positive associations between LPA and positive affect (30min: β = 0.03, p = <.001, 60min: β = 0.03, p = <.001), and self-esteem (30min: β = 0.01, p = .047 60 min: β = 0.01, p = <.001) were found. For SB negative associations for positive affect (30 min: β = -0.04, p = <.001, 60 min: β = -0.03, p = <.001), and self-esteem (30 min: β = -0.02, p = < .001, 60 min: β = -0.01, p = < .001) were found. No associations were found between any PAB and negative affect, and for MVPA and SMW. ConclusionThe significant positive associations between LPA and SMW and the negative associations between SB and SMW suggest that increasing LPA and decreasing SB and can improve SMW in VET students.

Can incidental physical activity offset the deleterious associations of sedentary behaviour with major adverse cardiovascular events?

Incidental physical activity as part of daily living may offer feasibility advantages over traditional exercise. We examined the joint associations of incidental physical activity and sedentary behaviour with major adverse cardiovascular events (MACE) risk. Analyses included 22,368 non-exercising adults from the UK Biobank accelerometry sub-study (Median age [IQR]: 62.9 [11.6] years; 41.8% male). Physical activity and sedentary behaviour exposures were derived using a machine learning-based intensity and posture classification schema. We assessed the tertile-based joint associations of sedentary behaviour and: a) incidental vigorous (VPA), b) incidental moderate to vigorous (MVPA), c) vigorous intermittent lifestyle physical activity (VILPA; bouts lasting up to 1 minute), and d) moderate to vigorous intermittent lifestyle physical activity (MV-ILPA; bouts lasting up to 3 minutes) with MACE risk. Over an 8.0-year median follow-up, 819 MACE events occurred. Compared to the highest physical activity and lowest sedentary time, high sedentary behaviour (>11.4 hours/day) with low incidental VPA (<2.1 minutes/day) had an HR of 1.34 (95% CI: 0.98, 1.84) and low incidental MVPA (<21.8 minutes/day) had a 1.89 HR (95% CI: 1.42, 2.52) for MACE. Sedentary behaviour was not associated with MACE at medium and high levels of VPA or VILPA. Completing 4.1 minutes/day of VPA or VILPA may offset the MACE risk associated with high sedentary behaviour. Conversely, 31-65 minutes of incidental MVPA or 26-52 minutes of MV-ILPA per day largely attenuated the associations with MACE. Brief intermittent bursts of vigorous incidental physical activity may offset cardiovascular risks from high sedentary behaviour.

Do personality profiles contribute to patterns of physical activity and sedentary behavior in adulthood? A prospective cohort study

BackgroundDespite the observed associations of personality traits with levels of moderate-to-vigorous physical activity (MVPA) and sedentary behavior (SB), studies exploring whether the personality profiles differ in terms of the pattern of accumulation of physical behavior are lacking. The aim of this study was to identify adults’ personality profiles and to characterize and investigate how these profiles differ in physical behavior.MethodsThe study utilized the longitudinal data of the participants of the Jyväskylä Longitudinal Study of Personality and Social Development (n = 141–307). Information on the five-factor model of personality, including the traits of neuroticism, extraversion, conscientiousness, openness, and agreeableness, was collected at ages 33, 42, 50, and 61 years, and used to create latent personality profiles. Physical behavior, operationalized as the amount and accumulation of MVPA and SB bouts, was captured using a triaxial accelerometer worn during waking hours at age 61 years. The differences in the behavior between the personality profiles were analyzed using the Kruskal-Wallis test.ResultsFive personality profiles were identified: resilient (20.2%), brittle (14.0%), overcontrolled (9.8%), undercontrolled (15.3%), and ordinary (40.7%). Although there were no statistically significant differences between the personality profiles in the time spent in MVPA relative to SB (MVPA per hour of daily SB), individuals with resilient (low in neuroticism and high in other traits) and ordinary (average in each trait) profiles had MVPA-to-SB ratios of 0.12 (7 min) and those with a brittle (high in neuroticism and low in extraversion) profile had a ratio of 0.09 (5.5 min). The individuals in the resilient group exhibited a longer usual MVPA bout duration than those in the overcontrolled (low in extraversion, openness, and agreeableness) (8 min vs. 2 min) and undercontrolled (high in openness and low in conscientiousness) groups (8 min vs. 3 min). They also exhibited a longer usual SB bout duration than those in the ordinary group (29 min vs. 23 min).ConclusionsThe resilient group displayed the most prolonged MVPA and SB bout patterns. The results suggest that personality characteristics may contribute to how MVPA and SB are accumulated.
