Physical Activity Levels In Adults Research Articles

Physical activity on prescription for children with obesity: a focus group study exploring experiences in paediatric healthcare.

Insufficient physical activity is a growing public health concern and is closely linked to obesity in both adults and children. Swedish physical activity on prescription (PAP) is effective in increasing physical activity levels in adults, but knowledge about how PAP is used in paediatric healthcare is lacking. Therefore, this study aimed to explore experiences of working with PAP for children with obesity amongst paediatric staff and managers. Seven focus group discussions with 26 participants from paediatric outpatient clinics in western Sweden were conducted. Data were analysed both inductively and deductively, framed by the Normalization Process Theory's four core constructs: coherence, cognitive participation, collective action, and reflexive monitoring. The PAP work for children with obesity was experienced to be about helping children to become physically active, and less about losing weight. Identified barriers for using PAP were the non-uniform nature of the work and a perceived lack of guidelines. Collaboration with physiotherapists and physical activity organisers outside the organisation was identified as an important facilitator. An important contextual factor for implementing PAP is the collaboration between paediatric clinics and physical activity organisers. In the transition between these stakeholders, maintaining a family-centred approach when working with PAP was experienced as challenging. PAP is a well-known intervention that is inconsistently used for children with obesity. The intervention should include a family-centred approach for this patient group. It also needs to align better with existing collaborations with other healthcare units as well as with new forms of collaboration with physical activity organisers in the community.

DETERMINING FACTORS AFFECTING OF THE PHYSICAL ACTIVITY LEVEL OF OLDER ADULTS DURING THE COVID-19 PANDEMIC

Objective: Social isolation during the COVID-19 pandemic adversely affected the physical and psychological conditions of the elderly. This study was planned to determine the factors affecting the physical activities of elderly individuals living in Turkey.
 Method: In this study, frailty level (Fragility Scale), depressive symptoms (Geriatric Depression Scale [GDS]), physical activity level (PASE Questionnaire), kinesiophobia (TAMPA Scale), and anxiety (Beck Anxiety Scale) of elderly individuals were evaluated by a structured Google survey. Regression analysis was used to determine the factors affecting the level of physical activity.
 Results: While 52% of the participants (28% male; 72% female; mean age: 69.34±15.03 years) stated that they were less physically active, 93% stated that their social participation decreased during the pandemic process. The mean physical activity score was 89.12±55.33 (the highest score was calculated for indoor activities: 32.00±21.34; the lowest score was calculated for work-related activities: 2.10±6.33). Kinesiophobia score was 41.44±7.39. Approximately half of the participants were in the category of “guarantees a comprehensive assessment for depression”, while 18% were in the category of “suggesting depression” and 30% were in the category of “no depression” (GDS mean score: 14.41±6.01). In addition, it was determined that 29% of the elderly had severe anxiety, 25% had moderate anxiety, and 24% had mild anxiety. The mean frailty score was 2.09±1.69 (normal 19%; pre-fragile 53%; frail 28%). According to univariate linear regression analysis and multiple regression analysis, the most factors affecting the level of physical activity were age, BMI score, fear of movement and fragility.
 Conclusion: The results obtained from this study showed that the physical activity level of the elderly decreased in the first year of the COVID-19 pandemic. In addition, increasing age, BMI score, kinesiophobia and fragility caused a decrease in the physical activity level of the elderly. These findings suggest that health policy makers and health care providers should organize appropriate care plans for the elderly after the pandemic period.

Gait speed and kinesiophobia explain physical activity level in adults with osteoarthritis: A cross-sectional study.

Identifying potential contributing factors for physical inactivity in people with knee osteoarthritis is vital for designing practical activity promoting interventions. Walking is a common activity, but it is unknown how gait characteristics may influence physical activity and if psychological factors, specifically fear of movement (kinesiophobia), contribute to this relationship. The aim of our study was to investigate the contributions of select gait parameters and kinesiophobia to activity levels. Cross-sectional data from 40 participants (F 24|M 16; age 57.6 ± 8.9 years; BMI 34.7 ± 7.0 kg/m2 ) with uni- or bilateral knee osteoarthritis were included. Physical activity and kinesiophobia were assessed by self-report using the University of California, Los Angeles activity rating scale, and Tampa scale for kinesiophobia, respectively. Gait parameters were collected with three-dimensional gait analysis while participants walked on an instrumented split-belt treadmill at a self-selected speed. Higher peak sagittal plane joint moments at the ankle (ρ = 0.418, p = 0.007), and hip (ρ = 0.348, p = 0.028), faster self-selected gait speed (ρ = 0.553, p < 0.001), and less kinesiophobia or fear of movement (ρ = -0.695, p < 0.001) were independently related to higher physical activity level in adults with knee osteoarthritis. In hierarchical regression models, after accounting for covariates, only self-selected gait speed, and kinesiophobia significantly contributed to explaining the variation in physical activity level. Statement of clinical significance: Interventions aimed at improving physical activity participation in those with lower limb osteoarthritis should consider assessing the contribution of pain-related fear of movement.

Environmental correlates of adolescent active travel to school in Asia: An ecological study.

This study aimed to examine the association between country-level environmental correlates and the prevalence of active school travel (AST) in Asia and country-level differences in AST by age and sex. This ecological study involved 31 Asian countries. Dependent variables were AST prevalence, AST prevalence difference by age, and by sex. Independent variables were country-level environmental correlates extracted using publicly available datasets, classified into physical and social environments. Association estimates of each dependent variable and each of the independent variables were calculated using univariate linear regression. All variables were standardized to have a mean of 0 and a standard deviation of 1. Results showed that 1 standard deviation (SD) difference in urban population percentage, night-time light, secondary-school enrolment, and prevalence of adult insufficient physical activity were negatively associated with AST prevalence (SD difference: -0.44 (-0.78 to -0.09), -0.40 (-0.76 to -0.04), -0.39 (-0.74 to -0.04), and -0.40 (-0.76 to -0.03), respectively). A 1 SD difference in car per people was associated with a -0.46 (-0.84 to -0.09) difference of AST prevalence by age. A 1 SD difference in PM2.5 concentration and of prevalence of adult insufficient physical activity were associated with a difference of 0.38 (0.01-0.74) and 0.42 (0.03-0.80) difference of AST prevalence by sex. This study shows that Asian countries with a greater number of people living in urban areas, lower levels of overall adult physical activity and higher levels of night-time light have a lower prevalence of adolescent AST. Country-level physical and social environmental correlates explained some of the regional variance in AST. Future policy actions and interventions for the region need to be contextually sensitive to the environmental correlates that vary between countries.

Prerequisites for implementing physical activity on prescription for children with obesity in paediatric health care: A cross-sectional survey.

Physical inactivity is a main driver of childhood obesity that tracks into adulthood, making it crucial to address early in life. Swedish physical activity on prescription (PAP) is an effective intervention for increasing physical activity levels in adults and is being implemented in primary care in Sweden. Before implementing PAP for children, both intervention effectiveness and implementation prerequisites need to be examined. Framed by the Normalization Process Theory (NPT) domains, this study aimed to investigate perceptions of PAP amongst paediatric staff and managers working with children with obesity, as well as acceptability, appropriateness, feasibility, and barriers and facilitators for implementing PAP in paediatric health care. Staff and managers in 28 paediatric outpatient clinics in western Sweden were surveyed using validated implementation instruments and open-ended questions. Data were analysed using Mann-Whitney U tests and Kruskal-Wallis tests. Qualitative data were categorised into NPT domains. The survey response rate was 54% (125/229). Most respondents (82%) reported PAP to be familiar and many (56%) perceived it as a normal part of work; nurses and physiotherapists to a greater extent (p < 0.001). This was anticipated to increase in the future (82%), especially amongst those with the longest work experience (p = 0.012). Respondents reported seeing the potential value in their work with PAP (77%), being open to working in new ways to use PAP (94%), and having confidence in their colleagues' ability to use PAP (77%). Barriers and facilitators were found in all the NPT domains, mainly collective action and reflexive monitoring, where, for example, inadequacies of education, resources, and research on PAP for children were reported as barriers. Most respondents agreed that PAP was acceptable, appropriate, and feasible (71% to 88%). PAP is familiar and perceived as an acceptable, appropriate, and feasible intervention, and by many viewed as a normal part of clinical routines in paediatric outpatient clinics in western Sweden, especially by physiotherapists and nurses. Barriers and faciliators are mainly related to collective action and reflexive monitoring. The wide acceptance demonstrates receptiveness to PAP as an intervention to promote an active lifestyle for children with obesity.

Physical activity levels in adults with chronic low back pain: A national survey in the general Spanish population

To identify and compare physical activity levels in the Spanish population with chronic low back pain and their associated factors. Cross-sectional national study. A total of 3,220 adults with chronic low back pain from the 2017 Spanish National Health Survey. Three groups were defined according to physical activity level (low, moderate, and high) assessed with the International Physical Activity Questionnaire. Descriptive analysis and an ordinal regression model were performed. Thirty percent of the subjects were classed as doing a low level of physical activity, 53% moderate, and 17% high. Females predominated in the low and moderate groups, and the subjects in the high group were younger. Subjects in the low group reported more use of pain-relief, more severe-extreme pain, more functional limitations, and worse quality of life and mental health. Factors more likely to be associated with higher levels of physical activity were: being male, normal body mass index or overweight, better health status, less pain, less physical and cognitive limitations, and more social support. Different aspects of the biopsychosocial framework were associated with the different levels of physical activity in subjects with chronic low back pain. These findings should be taken into consideration in order to establish suitable public health strategies.

A consensus method for estimating physical activity levels in adults using accelerometry

ABSTRACT Identifying the best analytical approach for capturing moderate-to-vigorous physical activity (MVPA) using accelerometry is complex but inconsistent approaches employed in research and surveillance limits comparability. We illustrate the use of a consensus method that pools estimates from multiple approaches for characterising MVPA using accelerometry. Participants (n = 30) wore an accelerometer on their right hip during two laboratory visits. Ten individual classification methods estimated minutes of MVPA, including cut-point, two-regression, and machine learning approaches, using open-source count and raw inputs and several epoch lengths. Results were averaged to derive the consensus estimate. Mean MVPA ranged from 33.9–50.4 min across individual methods, but only one (38.9 min) was statistically equivalent to the criterion of direct observation (38.2 min). The consensus estimate (39.2 min) was equivalent to the criterion (even after removal of the one individual method that was equivalent to the criterion), had a smaller mean absolute error (4.2 min) compared to individual methods (4.9–12.3 min), and enabled the estimation of participant-level variance (mean standard deviation: 7.7 min). The consensus method allows for addition/removal of methods depending on data availability or field progression and may improve accuracy and comparability of device-based MVPA estimates while limiting variability due to convergence between estimates.

Impact of Social Support on Physical Activity in Adults With Heart Failure: The Mediating Effect of Resilience.

This study aimed to evaluate the impact of resilience and social support on physical activity in adults with heart failure (HF) and to explore the mediating effect of resilience on the relationship between social support and physical activity. A cross-sectional study was conducted with 197 adults with HF (n = 197) from two outpatient departments for cardiovascular diseases. Resilience was assessed using the Connor-Davidson Resilience Scale, social support using the Social Support Rating Scale, and physical activity using the short form of the International Physical Activity Questionnaire. Social support and resilience were significantly associated with physical activity in adults with HF. Resilience partially mediated the relationship between social support and physical activity, and the mediating effect accounted for 25.93% of the total effect of social support on physical activity. These findings contribute to the development of tailored interventions by targeting these two factors to increase physical activity levels in adults with HF.

Systematic Review and Meta-Analysis of Primary Care-Based Physical Activity Interventions Among Older Adults.

The purpose of this research is to identify the effectiveness of primary care-based interventions designed to increase older adults' physical activity (PA). Primary care was defined as a patient's main source of health care. Standardized mean difference effect size (ES) was calculated related to changes in PA levels in adults' ≥65. Moderator analysis was performed to explore the relationship between participant characteristics, interventions, interventionists, and ES. Overall mean ES 0.27 (95% confidence interval [0.15, 0.39], p < .01) was calculated for 25 two-group comparisons involving 4,685 total participants with a mean age of 75.08. There was little evidence to support counseling over exercise referrals. The use of theory or a pedometer did not modify the ES. PA interventions delivered in primary care are effective and can be delivered by other health-care providers working with the primary provider. Many different behavior change strategies may be used to promote PA.

Physical Activity and Risk of Hepatocellular Carcinoma: A Systematic Review and Meta-Analysis.

Physical activity offers promise to protect against multiple non-hepatic primary cancers. We performed a systematic review to quantify the association between physical activity and hepatocellular carcinoma (HCC) risk. We searched the Cochrane Library, Embase, Medline and trial registries through December 2020 for studies that measured physical activity levels in adults at risk for HCC. The primary outcome was HCC. Subgroup analysis was performed limiting to vigorous physical activity. Proportions and random-effects odds ratios (OR) with corresponding 95% confidence intervals (CI) were calculated. Seven studies met inclusion criteria, comprising 777,662 subjects (median age 55years; 55% female). Greater amounts of physical activity were associated with less HCC (OR 0.65, 95% CI 0.45-0.95, p = 0.03) compared to lower amounts. Vigorous physical activity was associated with even less HCC (OR 0.62, 95% CI 0.49-0.79, p < 0.01). This meta-analysis demonstrates that greater amounts of physical activity are associated with lower odds of HCC. These results support the use of regular physical activity as an effective way to prevent HCC and provide helpful data to support a for future exercise-based interventional study to better define the optimal exercise prescription for patients at risk for primary liver cancer.

Implementation of physical activity on prescription for children with obesity in paediatric health care (IMPA): protocol for a feasibility and evaluation study using quantitative and qualitative methods

BackgroundPhysical inactivity is a main cause of childhood obesity which tracks into adulthood obesity, making it important to address early in life. Physical activity on prescription (PAP) is an evidence-based intervention that has shown good effect on physical activity levels in adults, but has not been evaluated in children with obesity. This project aims to evaluate the prerequisites, determinants, and feasibility of implementing PAP adapted to children with obesity and to explore children’s, parents’, and healthcare providers’ experiences of PAP.MethodsIn the first phase of the project, healthcare providers and managers from 26 paediatric clinics in Region Västra Götaland, Sweden, will be invited to participate in a web-based survey and a subset of this sample for a focus group study. Findings from these two data collections will form the basis for adaptation of PAP to the target group and context. In a second phase, this adapted PAP intervention will be evaluated in a clinical study in a sample of approximately 60 children with obesity (ISO-BMI > 30) between 6 and 12 years of age and one of their parents/legal guardians. Implementation process and clinical outcomes will be assessed pre- and post-intervention and at 8 and 12 months’ follow-up. Implementation outcomes are the four core constructs of the Normalization Process Theory; coherence, cognitive participation, collective action, and reflexive monitoring; and appropriateness, acceptability, and feasibility of the PAP intervention. Additional implementation process outcomes are recruitment and attrition rates, intervention fidelity, dose, and adherence. Clinical outcomes are physical activity pattern, BMI, metabolic risk factors, health-related quality of life, sleep, and self-efficacy and motivation for physical activity. Lastly, we will explore the perspectives of children and parents in semi-structured interviews. Design and analysis of the included studies are guided by the Normalization Process Theory.DiscussionThis project will provide new knowledge regarding the feasibility of PAP for children with obesity and about whether and how an evidence-based intervention can be fitted and adapted to new contexts and populations. The results may inform a larger scale trial and future implementation and may enhance the role of PAP in the management of obesity in paediatric health care in Sweden.Trial registrationClinicalTrials.gov Identifier: NCT04847271, registered 14 April 2021.

Changes to Physical Activity Levels in Adults Aged 50+ in the First Six Months of the COVID-19 Pandemic.

The purpose of this study is to qualitatively explore the impact of the COVID-19 pandemic on older adults’ PA nearly 6 months into the pandemic. Approximately 230 interviews were conducted with a diverse sample of participants (22.1% Black and 10.8% Hispanic). Data were transcribed in fall 2020 and analyzed using NVivo 12. Overall, most older adults (54.6%) interviewed reported no change in their PA, often reporting that their work kept them active. Decreases in PA for older adults (42.7%) were attributed to little social connectedness and stay-at-home restrictions. The few reporting an increase in PA (2.6%) had more time available to be active, including setting goals while staying home. This data provides an insight on how COVID-19 impacted PA levels for older adults. These findings can inform tailored interventions to promote PA during the pandemic.

Effect of childhood developmental coordination disorder on adulthood physical activity; Arvo Ylppö longitudinal study.

Individuals at risk of Developmental Coordination Disorder (DCD) have low levels of physical activity in childhood due to impaired motor competence; however, physical activity levels in adulthood have not been established. This study sought to determine the impact of DCD risk on physical activity levels in adults using accelerometry measurement. Participants (n = 656) from the Arvo Ylppö Longitudinal Study cohort had their motor competence assessed at the age of five years, and their physical activity quantified via device assessment at the age of 25 years. Between group differences were assessed to differentiate physical activity measures for individuals based on DCD risk status, with general linear modeling performed to control for the effects of sex, body mass index (BMI), and maternal education. Participants at risk of DCD were found to have a lower total number of steps (d = 0.3, p = 0.022) than those not at risk. Statistical modeling indicated that DCD risk status increased time spent in sedentary light activity (β = 0.1, 95% CI 0.02 to 0.3, p = 0.026) and decreased time spent in vigorous physical activity via interaction with BMI (β = 0.04, 95% CI 0.001 to 0.1, p = 0.025). Sensitivity analysis found that visuomotor impairment did not significantly impact physical activity but did increase the role of DCD risk status in some models. This 20‐year‐longitudinal study indicated that DCD risk status continues to negatively impact on levels of physical activity into early adulthood.

Accelerometer-based estimation of oxygen uptake in adults with Down syndrome: vector magnitude vs. vertical axis.

Triaxial accelerometer output [vector magnitude (VM) counts] may better estimate physical activity intensity as reflected in the rate of oxygen uptake (V̇O2 ) than the traditional vertical axis (VA) counts in adults with Down syndrome (DS). This study examined the accuracy of VM vs. VA counts in estimating V̇O2 in adults with and without DS across different physical activities and sedentary behaviours. Sixteen adults with DS (10 men and 6 women; 31±15years) and 19 adults without DS (10 men and 9 women; 24±5years) performed 12 tasks. V̇O2 was measured by portable spirometer (K4b2 , Cosmed) and VM and VA with an accelerometer (wGT3X-BT, Actigraph). Vector magnitude and VA were significant predictors of V̇O2 in adults with DS (P<0.001; R2 =0.74 and 0.65, respectively) and adults without DS (P<0.001; P<0.001; R2 =0.75 and 0.61, respectively). Absolute error of prediction was significantly smaller for VM than VA for sitting, playing app, drawing, sweeping, standing and basketball (P≤0.005), but smaller for VA than VM for walking at 0.8m·s-1 (P=0.005). Bland-Altman plots for adults with and without DS indicated narrower limits of agreement for VM than VA (-5.57 to 5.57 and -6.44 to 6.44mL·kg-1 ·min-1 ; -6.21 to 6.17 and -7.75 to 7.74mL·kg-1 ·min-1 , respectively). Vector magnitude and VA are significant predictors of V̇O2 in adults with and without DS, yet VM more accurately estimated V̇O2 than VA for most tasks. Development of accelerometer-based prediction of physical activity levels in adults with and without DS may improve by utilising VM counts.

Relationship between TV watching during childhood and adolescence and fitness in adulthood in the Raine Study cohort

ABSTRACT To investigate: (1) whether TV watching habits throughout childhood and adolescence, a proxy of sedentary behaviour, impacted cardiorespiratory fitness (CRF) in adulthood, and (2) whether any potential impact of TV watching in childhood and adolescence on CRF in adulthood was changed by adult physical activity (PA) levels. A longitudinal study with questionnaire data available regarding TV watching collected at ages 5, 8, 10, 14, 17 and 20 yrs, allowed trajectories of TV watching to be developed. At age 28 yrs, participants completed a V̇O2peak test and the International Physical Activity Questionnaire. General linear models tested for differences in CRF (time to exhaustion TTE and V̇O2peak mL·kg−1·min−1) between TV watching trajectories. The secondary analysis tested the potential effect current PA levels has on the relationship between TV trajectory and fitness. In total, 449 participants [male n = 255 (56.8%), 28.3 ± 0.5 yrs; female n = 194 (43.2%), 28.2 ± 0.4 yrs] were included in the study. Three distinct trajectories of TV watching were identified: High TV, Increasing TV and Low TV. CRF was lowest in the High TV watching trajectory and increased progressively from High to Increasing TV and Increasing to Low TV (all P < .05). Within each of the TV trajectories, those engaging in high levels of current PA had greater CRF than those engaging in low and moderate PA. TV watching in childhood and adolescence negatively impacts upon adult fitness at the age of 28 years. However, this negative impact of historical TV watching on CRF can largely be attenuated by engaging in higher levels of PA in adulthood. Highlights High levels of TV watching during childhood and adolescence have negative downstream impacts on cardiorespiratory fitness in adulthood. Taking part in high levels of physical activity in adulthood partially reverses the negative impact of historical TV watching on adult fitness. Engaging in low levels of TV watching throughout childhood and adolescence does not protect individuals from the detrimental impact of low current physical activity levels. Our findings support important public health messages with relevance to parents, schools and government; to target low levels of sedentary time throughout the developmental years of life, whilst encouraging the adoption of regular physical activity across the lifespan including young adulthood.

Level of engagement of recreational physical activity of urban villagers in Luohu, Shenzhen, China.

Physical activity is important for health. However, there is a lack of literature related to the physical activity levels of adults living in urban villagers, which is a vulnerable population in China. The aim of this study is to compare the physical activity and sedentary behavior engagements between urban villagers and non-urban villagers using the 2019 Luohu Shenzhen, China Community Diagnosis Questionnaire. A total of 1205 adults living in urban villages and non-urban villages were included in the analysis. Unadjusted and multiple multivariate logistic regression were conducted for the dependent variable of engagement in recreational physical activity, frequency of recreational physical activity per week, and hours spent in sedentary behaviors per day. Descriptive analysis was conducted to identify the reasons for not engaging in physical activity among urban villagers and non-urban villagers. Across the included sample, 29.05% were urban villagers and 70.95% were non-urban villagers. The results suggested that urban villagers are more likely to engage in physical activity than non-urban villager (OR = 1.90, 95% CI [1.40, 2.59], p < 0.001). However, it was also found that urban village status had no significant association for frequency in engaging in physical activity and average hours spent in sedentary behaviors. Both urban villagers and non-urban villages indicated that lack of time, lack of safe and appropriate environment, and working in labor intensive occupations as some of the reasons for not engaging in physical activity. There is a need for tailed interventions and policies for promoting physical activity among urban villagers and non-urban villagers. Additional studies are needed to further our understanding of the physical activity behaviors among urban villagers in China.

The relationship between multisite peripheral joint pain and physical activity levels in older adults: A cross-sectional survey.

Research on levels of physical activity (PA) in those with peripheral joint pain have only focused on single sites, in the knee or hips. This study investigated the levels of PA in adults with single-site and multisite peripheral joint pain compared to adults with no joint pain. Analysis of a cross-sectional population survey mailed to adults aged ≥45years (n=28,443) was conducted. Respondents reported any peripheral joint pain in the last 12months in either the hands, hips, knees or feet; PA levels were self-reported using the short telephone activity rating scale. The association between PA levels, peripheral joint pain and outcomes of health status (physical and mental component scores, using SF-12) pain intensity (10-point scale) and health-related quality of life (HRQoL) (EQ-5D) were investigated using analysis of variance and ordinal regressions. Compared to those with no joint pain, all pain groups reported lower levels of PA: joint pain in one site (odds ratio=0.91, 95% CI: 0.83-0.99); two sites (0.74, 0.67-0.81), three sites (0.65, 0.59-0.72) and four sites (0.47, 0.42-0.53). Across all joint pain groups, levels of PA were associated with pain intensity, physical health status, mental health status and HRQoL. Adults with more sites of peripheral joint pain were more likely to report lower levels of PA. Those with more sites of pain and lower levels of PA reported poorer outcomes. Health care providers should be aware that those with multisite joint pain are most likely to have low levels of PA.

Impact of social restrictions during the COVID-19 pandemic on the physical activity levels of adults aged 50–92 years: a baseline survey of the CHARIOT COVID-19 Rapid Response prospective cohort study

ObjectivesPhysical inactivity is more common in older adults, is associated with social isolation and loneliness and contributes to increased morbidity and mortality. We examined the effect of social restrictions to...

Applying theory to overcome internal barriers for healthy behavior change in adults with intellectual disabilities.

Adults with disabilities are 57% less physically active than individuals without disabilities and two times as likely to be obese. With obesity, adults with disabilities also face increased risk of comorbid disabilities stemming from obesity. The purpose of this theoretical case study was to identify key behavioral change theories which may be utilized to increase physical activity levels in adults with intellectual disabilities. The Self-Efficacy Theory and Self-Determination Theory both present constructs for understanding behavior change, and many of these constructs are interrelated which strongly suggests many behavioral change theories identify internal barriers for change. With theoretical case studies, these theories are examined within the context of adapted physical activity to depict how the Self-Efficacy Theory and Self-Determination Theory could be utilized to increase physical activity in individuals with intellectual disabilities.
