Background: This study tested for differences in personal, social, and environmental correlates of moderate to vigorous physical activity (MVPA) across ethnicity/race in male and female adolescents. Methods: Self-reported MVPA and 47 potential correlates of MVPA were measured in an ethnically/racially diverse cross-sectional sample of adolescents, in Minnesota, who participated in EAT-2010 (Eating and Activity in Teens). Interactions of potential correlates with ethnicity/race on MVPA were tested in linear hierarchical regression models in boys and girls. Results: Boys reported 1.7 more weekly hours of MVPA than girls. White adolescents reported 1.1 to 2.1 more weekly hours of MVPA than nonwhite adolescents. Among girls, neighborhood road connectivity was negatively correlated with MVPA among Hispanic and Asian participants. Among boys, sports participation was positively correlated with MVPA among all ethnicities/races, except Asians. Home media equipment was positively correlated with MVPA among Hispanic boys, but negatively correlated among white boys. Conclusions: A few correlates of physical activity among adolescents differed intersectionally by ethnicity/race and sex. Sports participation and home media equipment may have differing impacts on physical activity across ethnicities and races in boys, whereas neighborhood features like road connectivity may have differing impacts on physical activity across ethnicities and races in girls.

The purpose of this study was to examine the types and perceived usefulness of questionnaires used by consultants in applied intervention work with athletes in 2003 and 2017, as well as to understand consultants’ perceptions of the advantages, limitations, and needs regarding the use of questionnaires in consulting. Sport psychology consultants in 2003 (n = 96) and 2017 (n = 106) completed a questionnaire that included Likert-scale questions as well as open-ended questions. The percentage of consultants who used questionnaires decreased from 83% in 2003 to 67% in 2017. Consultants in 2003 rated questionnaires as more useful than consultants in 2017, although the specific questionnaires used by consultants did not change extensively over the 14-year period. Advantages in using questionnaires included efficiency, structure of assessment, consensual validation, and credibility, while limitations included lack of relevance, undermining of athlete-consultant relationship, interpretive problems, and cost and lack of access.

Background: Growing evidence suggests that the broader neighborhood socioeconomic environment is independently associated with cardiometabolic health. However, few studies have examined this relationship among younger populations. Purpose: The purpose of the study was to (1) investigate the association between neighborhood socioeconomic deprivation (SED) and cardiorespiratory fitness and (2) determine the extent to which physical activity mediates this relationship. Methods: Data from 312 youth (aged 12–15 y) were obtained from the 2012 National Health and Nutrition Examination Survey National Youth Fitness Survey. Cardiorespiratory fitness was measured using a standard submaximal treadmill test, and maximal oxygen consumption was estimated. Physical activity was self-reported time spent in moderate to vigorous activity. Neighborhood SED was measured by a composite index score at the census tract of residence. Logistic regression analyses examined relationships between neighborhood SED, physical activity, and cardiorespiratory fitness, adjusting for individual-level characteristics and the complex sampling design. Results: Neighborhood SED was not significantly associated with cardiorespiratory fitness or physical activity among youth in the study sample. Conclusions: While not significant, cardiorespiratory fitness levels were observed to decrease as neighborhood SED increased. Future research is needed to better understand this relationship and to identify underlying mechanisms beyond fitness or physical activity that may drive the relationship between neighborhood SED and health.

Background: The purpose of this study was to examine trajectories of leisure-time physical activity (LTPA) and television-viewing (TV) time and their associations in adults over 10 years. Methods: The sample comprised 2934 participants (men, 46.0%) aged 24–39 years in 2001 and they were followed up for 10 years. LTPA and TV time were assessed using self-report questionnaires in 2001, 2007, and 2011. Longitudinal LTPA and TV-time trajectories and their interactions were analyzed with mixture modeling. Results: Three LTPA (persistently highly active, 15.8%; persistently moderately active, 60.8%; and persistently low active, 23.5%) and 4 TV time (consistently low, 38.6%; consistently moderate, 48.2%; consistently high, 11.7%; and consistently very high, 1.5%) trajectory classes were identified. Persistently highly active women had a lower probability of consistently high TV time than persistently low-active women (P = .02), whereas men who were persistently highly active had a higher probability of consistently moderate TV time and a lower probability of consistently low TV time than their persistently low-active counterparts (P = .03 and P = .01, respectively). Conclusions: Maintaining high LTPA levels were accompanied by less TV over time in women, but not in men. The associations were partially explained by education, body mass index, and smoking.

Background: Identifying factors influencing the implementation of evidence-based environmental recommendations to promote physical activity in childcare services is required to develop effective implementation strategies. This systematic review aimed to: (1) identify barriers and facilitators reported by center-based childcare services impacting the implementation of environmental recommendations to increase physical activity among children, (2) synthesize these factors according to the 14 domains of the “Theoretical Domains Framework,” and (3) report any associations between service or provider characteristics and the reported implementation of such recommendations. Methods: Electronic searches were conducted in 6 scientific databases (eg, MEDLINE) and Google Scholar to identify studies reporting data from childcare staff or other stakeholders responsible for childcare operations. Included studies were based on childcare settings and published in English. From 2164 identified citations, 19 articles met the inclusion criteria (11 qualitative, 4 quantitative, and 4 mixed methods). Results: Across all articles, the majority of factors impacting implementation fell into the “environmental context and resources” domain (eg, time, equipment, and space; n = 19) and the “social influences” domain (eg, support from parents, colleagues, supervisors; n = 11). Conclusion: The current review provides guidance to improve the implementation of environmental recommendations in childcare services by addressing environmental, resource, and social barriers.

Background: A walking cadence of ≥100 steps/min corresponds to minimally moderate intensity, absolutely defined as ≥3 metabolic equivalents (METs). This threshold has primarily been calibrated during treadmill walking. There is a need to determine the classification accuracy of this cadence threshold to predict intensity during overground walking. Methods: In this laboratory-based cross-sectional investigation, participants (N = 75, 49.3% women, age 21–40 y) performed a single 5-minute overground (hallway) walking trial at a self-selected preferred pace. Steps accumulated during each trial were hand tallied and converted to cadence (steps/min). Oxygen uptake was measured using indirect calorimetry and converted to METs. The classification accuracy (sensitivity, specificity, overall accuracy, and positive predictive value) of ≥100 steps/min to predict ≥3 METs was calculated. Results: A cadence threshold of ≥100 steps/min yielded an overall accuracy (combined sensitivity and specificity) of 73.3% for predicting minimally moderate intensity. Moreover, for individuals walking at a cadence ≥100 steps/min, the probability (positive predictive value) of achieving minimally moderate intensity was 80.3%. Conclusions: Although primarily developed using treadmill-based protocols, a cadence threshold of ≥100 steps/min for young adults appears to be a valid heuristic value (evidence-based, rounded, practical) associated with minimally moderate intensity during overground walking performed at a self-selected preferred pace.

Background: To assess the joint and stratified associations between cardiorespiratory fitness (CRF), incidence, and mortality from cancer in never, former, and current male smokers. Methods: CRF (treadmill exercise test) was assessed in 4694 men (never smokers [n = 1715]; former smokers [n = 1602], 32.4 [30.5] pack-years; and current smokers [n = 1377], 40.3 [26] pack-years) aged 58.1 (17.3) years, and prospectively followed for 12.7 (7.5) years. Multivariable Cox hazard models were analyzed. Results: In joint analyses, where high CRF in never smokers was used as a reference, hazard ratios and 95% (confidence intervals) for cancer incidence and cancer mortality were as follows: moderate CRF 1.41 (1.0–1.9) and 3.0 (1.7–5.5) in never smokers, 1.65 (1.3–2.2) and 3.7 (2.1–6.6) in former smokers, and 1.3 (0.9–1.7) and 3.4 (1.9–6.1) in current smokers, respectively. The corresponding values for low CRF were 1.53 (1.1–2.2) and 5.1 (2.7–9.5), 1.84 (1.3–2.5) and 6.6 (3.7–11.8), and 1.5 (1.1–2.2) and 5 (2.7–9.3), respectively. In stratified analyses by smoking status, compared with low CRF, moderate and high CRF were associated with a 32% to 78% reduction in cancer mortality risk (P trend for all <.001). Conclusion: Higher CRF is associated with lower risk of incidence and mortality from cancer regardless of smoking status, supporting the potential preventive benefits for public health.

Evidence for the mechanisms of change by which sport psychology interventions enhance performance is limited and treatment monitoring and outcomes measures would assist in establishing evidence-based practices. The present paper fills a gap in sport psychology literature by demonstrating the development and validation of a new measure (Sport Psychology Outcomes and Research Tool; SPORT). Study 1 described test construction and pilot item selection with 73 collegiate student-athletes. Twenty-three pilot items contributed unique variance while maintaining the original constructs and were selected from 80 initial items. In Study 2, exploratory and confirmatory factor analyses were conducted with collegiate student-athletes (n = 220), revealing a 17-item, four-factor model measuring Athlete Wellbeing, Self-Regulation, Performance Satisfaction, and Sport-Related Distress. Concurrent validity was supported through correlational analyses. Overall, results supported the SPORT as a new transtheoretical tool for monitoring effectiveness and outcomes of sport psychology interventions.

Well-being research conducted in competitive athletics has been marred by the lack of a context-specific measurement instrument. The purpose of this study was to adapt the Mental Health Continuum – Short Form (MHC-SF) to create a sport-specific well-being instrument, the Sport Mental Health Continuum—Short Form (Sport MHC-SF), and test its initial psychometric properties. Participants were 287 collegiate athletes from a variety of sports. Confirmatory factor analysis (CFA) determined a three-factor structure of sport well-being, consisting of subjective, psychological, and social factors, as the model of best fit. Internal consistency reliabilities of the subscales exceeded .88. Moderate positive correlations were found between Sport MHC-SF subscales and quality of life indices, notably physical and emotional quality of life, demonstrating convergent validity. The Sport MHC-SF will facilitate empirical research by providing a more accurate and comprehensive measurement of well-being for an athletic population.

Background: The promotion of physical activity among imprisoned people is a public health strategy that could help to improve the health status of this collective. This systematic review is aimed at reviewing the scientific evidence regarding the effects of exercise training programs performed by inmates. Methods: A systematic search for randomized controlled trials aimed at identifying the characteristics and effects of prison-based exercise training programs on imprisoned people was carried through MEDLINE, SPORTDiscus, and Scopus. Results: A total of 11 randomized controlled studies were selected, and the methodological quality of these was acceptable according to the Downs and Black scale. The proposed interventions were mainly based on the performance of aerobic or combined exercise training programs. Generally, the participants were healthy men who were imprisoned for at least 2 months and up to 15 years. Ten out of the 11 studies reported significant changes on physical and mental health–related variables, after the intervention took place. Conclusion: These findings suggest that prison-based exercise programs constitute a feasible and useful strategy for improving the physical and mental health status of prisoners.
