Background: Total sedentary time and prolonged sedentary patterns can negatively impact health. This study investigated rates of various sedentary pattern variables in Hispanic/Latino youth. Methods: Participants were 956 youths (50.9% female) in the Hispanic Community Health Study/Study of Latinos Youth, a population-based cohort study of Hispanic/Latino 8- to 16-year-olds from 4 geographic regions in the United States (2012–2014). Total sedentary time and 10 sedentary pattern variables were measured through 1 week of accelerometer wear. Differences were examined by sociodemographic characteristics, geographic location, weekdays versus weekends, and season. Results: On average, youth were sedentary during 67.3% of their accelerometer wear time, spent 24.2% engaged in 10- to 29-minute sedentary bouts, and 7.2% in ≥60-minute bouts. 8- to 12-year-olds had more favorable sedentary patterns (less time in extended bouts and more breaks) than 13- to 16-year-olds across all sedentary variables. Sedentary patterns also differed by Hispanic/Latino background, with few differences across sex, household income, season, and place of birth, and none between weekdays versus weekends. Conclusions: Variables representing prolonged sedentary time were high among Hispanic/Latino youth. Adolescents in this group appear to be at especially high risk for unhealthy sedentary patterns. Population-based efforts are needed to prevent youth from engaging in increasingly prolonged sedentary patterns.

Background: The effect of globally recommended levels of physical activity on cognition and motor behavior is not completely understood. Therefore, the main aim of this study was to assess the effect of 300 minutes per week of moderate-intensity aerobic exercise on cognitive and motor performance among overweight and obese working-age women. Methods: Overweight and obese participants aged 38–56 years were randomized to either a control or an experimental group performing aerobic exercise at 50% to 60% of the peak oxygen consumption for a 2-month period. Changes in aerobic fitness, cardiac autonomic function, brain-derived neurotropic factor levels, and cognitive and motor performance were assessed. Results: Although aerobic exercise reduced body weight (P < .05) and improved peak oxygen consumption (P < .05), the brain-derived neurotropic factor levels and cognitive and motor performance remained unchanged. Heart rate and blood pressure decreased (P < .05), whereas heart rate variability indices were not affected. No significant correlations between changes in heart rate variability indices and cognition were observed. Conclusions: Two months of moderate-intensity aerobic exercise decreased sympathetic activity and improved cardiovascular fitness but had no impact on cognition or motor control among these middle-aged, overweight, and obese women.

Purpose: This study explored participant views of a web-based physical activity intervention for older adults and examined how they resonate with the key principles that guided intervention development. Methods: Qualitative interviews were carried out with 52 older adults. A deductive qualitative analysis approach was taken, based around the intervention’s key principles. Results: Participants expressed mostly positive views of the intervention features, broadly confirming the appropriateness of the key principles, which were to: (a) encourage intrinsic motivation for physical activity, (b) minimize the risk of users receiving activity suggestions that are inappropriate or unsafe, (c) offer users choice regarding the activities they engage with and build confidence to undertake more activity, and (d) minimize the cognitive load and need to engage with the intervention website. The findings also identified ways in which content could be improved to further increase acceptability. Conclusion: This study illustrates how using the person-based approach has enabled the identification and implementation of features that older adults appreciate.

This proof-of-concept study examined feasibility of assessing longitudinal changes in body mass index, strength, mobility, and cardiovascular health outcomes in older, racial/ethnic minority adults participating in a park-based physical activity program. Study feasibility was based on follow-through data collection procedures and ability to manage and implement data collection, enrollment, and repeated measures data collection in older adults (≥50 years; n = 380; 45% Hispanic, 41% non-Hispanic Black) over a 28-month period. Mixed models were developed to estimate the effects of program participation over time on participant cardiovascular and fitness outcomes and across poverty and age subgroups. Model estimates adjusted for individual-level sociodemographics showed improvements across each 4 month time point in arm strength (0.55 arm curl; 95% confidence interval [0.33, 0.77]) and systolic (−0.68 mmHg; 95% confidence interval [−1.22, −0.13]) and diastolic (−0.47 mmHg; 95% confidence interval [−0.79, −0.16]) blood pressure. An Age × Poverty interaction found greater improvements in systolic and diastolic blood pressure among younger participants living in low poverty (vs. older in higher poverty). Study of the longitudinal association between fitness class participation and health outcomes was feasible in park-based settings.

Social relationships are central to the health and well-being of older adults. Evidence exploring the association of physical activity (PA) with social isolation and loneliness is limited. This study uses a path analysis to investigate the longitudinal association between loneliness and social isolation with PA using the Irish Longitudinal Study on Ageing. Higher levels of social isolation measured using the Berkman–Syme Social Network Index were directly and indirectly associated with lower levels of walking, moderate PA, and vigorous PA over 6 years. Additionally, higher levels of walking were associated with lower levels of loneliness measured using a modified version of the University of California, Los Angeles loneliness scale over a 3-year period. Future interventions should target individuals who are more socially isolated and explore the effects of different types of PA on loneliness over time.

In two experiments, the authors investigated the influence of stress type (i.e., low/no stress, mental, and physical), level (i.e., low, moderate, and high), and Type × Level interaction on intuitive decision frequency, decision quality, and decision speed. Participants were exposed to mental (i.e., color word task, mental arithmetic) and/or physical stress (i.e., running) and then required to make decisions regarding videotaped offensive situations in basketball. Intuitive decision frequency, decision quality, and decision speed were measured for each trial. Study 1 used a between-subjects design whereby 20 participants were randomly assigned to each of the five stress conditions. Results revealed that moderate stress was associated with faster decisions. Study 2 replicated the design and aim of Study 1 using a within-subject methodology (n = 42). Results suggested that moderate stress levels produced better, faster decisions. In conclusion, moderate levels of stress were associated with the most desirable decision outcomes.

Background: Recent physical activity research is limited by intention–behavior discordance and is beginning to recognize the importance of automatic processes in exercise. The purpose of the current study was to examine the role of multidimensional exercise self-efficacy (SE), explicit–implicit evaluative discrepancies (EIEDs) for health, and appearance on the intention–behavior gap in exercise. Methods: A total of 141 middle-aged inactive participants (mean age = 46.12 [8.17] y) completed measures of intentions, SE, and explicit and implicit evaluations of exercise outcomes. The participants were classified as inclined actors (n = 107) if they successfully started the exercise program and inclined abstainers (n = 35) if they were not successful. Results: The inclined actors and abstainers did not differ on intentions to exercise; however, the inclined actors had higher coping SE and lower EIEDs for health. In addition, the coping SE (Exp [β] = 1.03) and EIEDs for health (Exp [β] = −0.405) were significant predictors of being an inclined actor. Conclusions: The interaction between explicit and implicit processes in regard to health motives for exercise appears to influence the successful enactment of exercise from positive intentions. As most physical activity promotion strategies focus on health as a reason to be active, the role of implicit and explicit evaluations on behavioral decisions to exercise may inform future interventions.

Background: Aerobic exercise is recommended for reducing blood pressure; however, recent studies indicate that stretching may also be effective. The authors compared 8 weeks of stretching versus walking exercise in men and women with high–normal blood pressure or stage 1 hypertension (ie, 130/85–159/99 mm Hg). Methods: Forty men and women (61.6 y) were randomized to a stretching or brisk walking exercise program (30 min/d, 5 d/wk for 8 wk). Blood pressure was assessed during sitting and supine positions and for 24 hours using a portable monitor before and after the training programs. Results: The stretching program elicited greater reductions than the walking program (P < .05) for sitting systolic (146  to 140  vs 139  to 142  mm Hg), supine diastolic (85  to 78  vs 81  to 82  mm Hg), and nighttime diastolic (67  to 65  vs 68  to 73  mm Hg) blood pressures. The stretching program elicited greater reductions than the walking program (P < .05) for mean arterial pressure assessed in sitting (108  to 103  vs 105  vs 105  mm Hg), supine (102  to 96  vs 99  to 99  mm Hg), and at night (86  to 83  vs 88  to 93  mm Hg). Conclusions: An 8-week stretching program was superior to brisk walking for reducing blood pressure in individuals with high–normal blood pressure or stage 1 hypertension.

The purpose of this study was to evaluate the effectiveness of the Fun For Wellness (FFW) online intervention to increase well-being actions in adults with obesity in the United States in relatively uncontrolled settings. The FFW intervention is guided by self-efficacy theory. The study design was a large-scale, prospective, double-blind, and parallel-group randomized controlled trial. Data collection occurred at baseline, 30 days after baseline, and 60 days after baseline. Participants (N = 667) who were assigned to the FFW group (n FFW = 331) were provided with 30 days of 24-hr access to FFW. Supportive evidence was provided for the effectiveness of FFW in real-world settings to promote, either directly or indirectly, three dimensions of well-being actions: community, occupational, and psychological. This study shows that theory-based intervention may be effective in promoting well-being actions in adults with obesity in the United States.

The adoption of compensatory movement patterns occurs when limitations in mobility, stability, or motor control prevent proper motion from occurring. These dysfunctional movements may inhibit fundamental motor skill development and negatively influence perceived movement competence, impeding the development of physical literacy. Therefore, this study examined the relationship between functional movement and perceived and actual motor skill competence in young adolescents. Functional movement proficiency was determined using the Functional Movement Screen (FMS™), which provides three variables of interest: (a) FMS™ total score, (b) number of asymmetries, and (c) number of movement pattern dysfunctions. Perceived physical competence was assessed through the Children and Youth Physical Self-Perception Profile. Finally, the Get Skilled: Get Active process-oriented motor skill assessment was used to evaluate vertical jump, kick, run, and overhand throw proficiency. A significant positive correlation between FMS™ total score and vertical jump performance was found. A positive relationship was also found between the number of asymmetries and overhand throw performance. The Children and Youth Physical Self-Perception Profile constructs of body attractiveness and physical condition were positively associated with FMS™ total score, and physical condition was also shown to be inversely related to the number of movement pattern dysfunctions. Results suggest that functional movement may underpin movement competence and confidence.
