Introduction: In 2016, the 2018 Physical Activity Guidelines Advisory Committee, a group of experts in exercise science and health, began an extensive review of the literature to inform the second edition of the Physical Activity Guidelines for Americans. Methods: The purpose of this paper is to describe the evidence-based methodology used to review, evaluate, and synthesize published, peer-reviewed physical activity research. The protocol-driven methodology was designed to maximize transparency, minimize bias, and ensure relevant, timely, and high-quality systematic reviews. Training protocols, quality control procedures, search strategies, assessment instruments, abstraction guides and forms, and reporting templates were developed. Results: A systematic approach was used to select the evidence for the 2018 Physical Activity Guidelines Advisory Committee Scientific Report that included umbrella reviews and systematic reviews. Within 16 months, 38 searches were conducted; and 20,838 titles, 4913 abstracts, and 2139 full texts were triaged. Of those, 1130 articles were abstracted to answer 38 research questions. Conclusions: To inform population-based physical activity guidelines, this systematic process facilitated a vast review of the literature on physical activity and health in a short period of time. This flexible, yet rigorous and transparent process included a clear and detailed methodology with a focus on training and quality control.

Meta Analyses

Background: Systematic reviews (SRs) and meta-analyses (MAs) have proliferated with a concomitant increase in reviews of SRs/MAs or “meta-reviews” (MRs). As uncovered by the 2018 US Physical Activity Guidelines Advisory Committee (PAGAC), there is a paucity of best practice guidance on MRs on physical activity health-related research. This manuscript aims to fill this gap. Methods: In total, the PAGAC conducted 38 literature searches across 3 electronic databases and triaged 20,838 titles, 4913 abstracts, and 2139 full texts from which 1130 articles qualified for the PAGAC Scientific Report. Results: During the MR process, the following challenges were encountered: (1) if the SR/MA authors had limited experience in synthesis methodology, they likely did not account for risk of bias in the conclusions they reached; (2) many SRs/MAs reviewed the same primary-level studies; (3) many SRs/MAs failed to disclose effect modifier analyses; (4) source populations varied; (5) physical activity exposures were nonstandardized; and (6) dose–response effects or effect modification of the physical activity exposure could not be identified. Conclusions: Using examples from the PAGAC Scientific Report, we provide (1) a high-level introduction to MRs; (2) recommended steps in conducting a MR; (3) challenges that can be encountered; and (4) guidance in addressing these challenges.

ObjectivesTo understand how device-measured sedentary behaviour and physical activity are related to all-cause mortality in older men, an age group with high levels of inactivity and sedentary behaviour.MethodsProspective population-based cohort study of men recruited from 24 UK General Practices in 1978–1980. In 2010–2012, 3137 surviving men were invited to a follow-up, 1655 (aged 71–92 years) agreed. Nurses measured height and weight, men completed health and demographic questionnaires and wore an ActiGraph GT3x accelerometer. All-cause mortality was collected through National Health Service central registers up to 1 June 2016.ResultsAfter median 5.0 years’ follow-up, 194 deaths occurred in 1181 men without pre-existing cardiovascular disease. For each additional 30 min in sedentary behaviour, or light physical activity (LIPA), or 10 min in moderate to vigorous physical activity (MVPA), HRs for mortality were 1.17 (95% CI 1.10 to 1.25), 0.83 (95% CI 0.77 to 0.90) and 0.90 (95% CI 0.84 to 0.96), respectively. Adjustments for confounders did not meaningfully change estimates. Only LIPA remained significant on mutual adjustment for all intensities. The HR for accumulating 150 min MVPA/week in sporadic minutes (achieved by 66% of men) was 0.59 (95% CI 0.43 to 0.81) and 0.58 (95% CI 0.33 to 1.00) for accumulating 150 min MVPA/week in bouts lasting ≥10 min (achieved by 16% of men). Sedentary breaks were not associated with mortality.ConclusionsIn older men, all activities (of light intensity upwards) were beneficial and accumulation of activity in bouts ≥10 min did not appear important beyond total volume of activity. Findings can inform physical activity guidelines for older adults.

Background: Compared to traditional non-active video games, exergaming may contribute significantly to overall daily physical activity (PA), but the association in population-based samples has not been fully explored. Objectives: To assess whether total minutes of PA per week among exergamers differs from non-exergamers, and whether the likelihood of meeting PA guidelines differs between exergamers and non-exergamers. Methods: Data were available from the 2011-2012 wave of the Nicotine Dependence in Teens (NDIT) study (n=829). Multivariable models assessed the association between exergaming with moderate, vigorous, and moderate-to-vigorous PA (MVPA) minutes in the past week, and the association between exergaming and meeting PA guidelines after adjusting for age, household income, employment status, education, weight status, and screen time. Exergaming was defined as use ≥ 1-3 times per month in the past year, and PA guidelines were defined as ≥ 150 minutes of moderately intense PA, or ≥ 75 minutes of vigorously intense PA, or a combination. Minutes of PA were measured using the well-validated International Physical Activity Questionnaire. Sex differences in exergaming use and exergaming beliefs and attitudes were also assessed. Results: In this population-based sample of young adults (mean age 24 [SD: 0.7] years, 55% female [n=455]), 18% (n=148) of the participants were exergamers (54% female, n=80). Exergaming males and females reported an average of 88.4 and 65.7 exergaming minutes in the past week, respectively. Compared to male exergamers, female exergamers were more likely to believe that exergaming is a good way to integrate PA into their lives (p<0.001), were more likely to prefer exergaming to indoor/outdoor sports (p=0.03), and were more likely to use fitness-training exergames at home (p=0.006). Perceived levels of exertion were also significantly different between male and female exergamers. The majority of male exergamers reported light (51%, n=23) or moderate (44%, n=20) exergaming exertion, whereas female exergamers reported moderate (53%, n=30), as well as light (28%, n=16) and intense (19%, n=11) exertion (p=0.02). After adjusting for covariates, male exergamers were not significantly different from male non-exergamers in total minutes of PA per week, but female exergamers reported 47 more minutes of moderate PA in the past week compared to female non-exergamers (p=0.03). There was no association between exergaming and meeting PA guidelines in either males or females. Conclusions: Exergaming contributes to moderate-intensity PA among females but not among males in this population based sample of young adults. Exergaming may therefore be an important source of PA for women, but the current landscape of exergames may be inadequate to substantially increase minutes of PA among males. Differences in attitudes toward exergaming should be further explored.

Background: Dissemination of the Physical Activity Guidelines for Americans (Guidelines) is needed, but how individuals respond to the Guidelines is not well understood. This surveillance study describes US adults’ reported responses to and information sources for hearing about the Guidelines and explores relationships between how respondents heard about the Guidelines and their reported response(s). Methods: Data were analyzed from the population-based 2019 Health Information National Trends Survey 5 Cycle 3. Population-weighted proportions of response were calculated. Among those who had heard about the Guidelines, binary logistic regressions examined associations between the reported response(s) and the information source and number of sources reported. Results: The analytical sample included 5047 adults. Nearly 65% of US adults reported hearing about the Guidelines, and 29% reported a behavioral response (eg, increased physical activity). Hearing about the Guidelines through health professionals (adjusted odds ratio = 2.30, 95% confidence interval, 1.45–3.65) or social media (adjusted odds ratio = 1.89, 95% confidence interval, 1.20–2.96) (vs other sources) was associated with reporting increasing physical activity. Hearing from multiple sources (vs one source) was associated with reporting increasing physical activity (adjusted odds ratio = 1.97, 95% confidence interval, 1.18–3.31). Conclusion: Findings suggest dissemination of the Guidelines across multiple channels may promote greater changes in physical activity.

Mechanisms Of Mindfulness

Mindfulness is gaining increased attention as a means of increasing physical activity (PA) participation. Given that only 15.4% of adult Canadians currently meet the Canadian Physical Activity Guidelines (Colley et al., 2011), it is imperative to find ways to increase PA among adults. One way to do this is to promote self-regulation skills as self-regulation is among the top predictors of PA participation (Teixeira et al., 2015).  The purpose of this narrative review was to further understand the role of self-regulation as a potential mechanism by which mindfulness may be related to PA participation. Initially, 160 papers were identified by title for this review. After reading abstracts, 37 papers were identified as possibly relating to the topic of interest. Following full readings, 26 papers were included in the final review. Likely due to the novelty of this topic, there is limited research on the mechanisms by which mindfulness may be related to physical activity. Review of the literature suggests that self-regulation appears to be a promising mechanism by which mindfulness could improve physical activity participation (Shapiro et al., 2006; Samdal et al., 2017), as self-regulation has been shown to play an important role in behaviour change, however, other alternative mechanisms include improved self-efficacy, as well as improved satisfaction (Neace et al., 2020; Tsafou et al., 2016). The authors conclude that more research on the mechanisms of mindfulness on PA, specifically self-regulation as a mechanism, could foster more knowledgeable intervention practices, and consequently improve mindfulness-based interventions efficacy.

This paper reviews the descriptive epidemiology of physical activity in adolescents. Large population-based studies were reviewed, along with smaller studies using objective monitoring of physical activity. Estimates showed that adolescents engage in physical activity of any intensity for a mean of one hour per day. Approximately two thirds of males and one quarter of females participate in moderate to vigorous activity for 20 min 3 or more days per week. Activity levels decline with increasing age across adolescence, and this decrease is more marked in females than in males. Comparison of these data to physical activity guidelines for adolescents suggests the vast majority are meeting the guideline of accumulating physical activity. However, a substantial number of males, and the majority of females, are not meeting the guideline for moderate to vigorous physical activity.

Physical Activity Guidelines

The Canadian Society for Exercise Physiology (CSEP), in cooperation with ParticipACTION and other stakeholders, and with support from the Public Health Agency of Canada (PHAC), has developed the new Canadian Physical Activity Guidelines for Children (aged 5–11 years), Youth (aged 12–17 years), Adults (aged 18–64 years), and Older Adults (aged ≥65 years). The new guidelines include a preamble to provide context and specific guidelines for each age group. The entire guideline development process was guided by the Appraisal of Guidelines for Research Evaluation (AGREE) II instrument, which is the international standard for clinical practice guideline development. Thus, the guidelines have gone through a rigorous and transparent developmental process; we based the recommendations herein on evidence from 3 systematic reviews, and the final guidelines benefitted from an extensive online and in-person consultation process with hundreds of stakeholders and key informants, both domestic and international. Since 2006, the products of our efforts resulted in the completion of 21 peer-reviewed journal articles (including 5 systematic reviews) that collectively guided this work. The process that Canadian researchers undertook to update the national physical activity guidelines represents the most current synthesis, interpretation, and application of the scientific evidence to date.

La motivación de los adolescentes hacia la Actividad Física (AF) es un problema que se acaba traduciendo en sedentarismo y el resultado será una sociedad con pocos hábitos hacia la vida saludable y hacia la actividad diaria. En secundaria se hace especialmente necesario investigar los factores que pueden incidir en que los estudiantes alcancen una motivación positiva en Educación Física (EF). El sedentarismo se ha identificado como un factor de riesgo en el desarrollo de enfermedades crónicas, la obesidad, la diabetes tipo II o diversas enfermedades cardiovasculares (Physical Activity Guidelines Advisory Committee, 2008; Sallis y Owen, 1999). Responsables y expertos de distintos países en materia de salud consideran un objetivo prioritario de salud pública la promoción de la actividad física entre los jóvenes (Welk, Eisenmann y Dollman, 2006). Las últimas investigaciones han olvidado que los adolescentes mientras están en el aula también se pueden sentir competentes o con éxito en dominios distintos al académico (Urdan y Maehr, 1995). El profesorado constituye una pieza clave, no sólo actúa por mediación de sus competencias profesionales sino también en función de su labor social y educativa, de su pensamiento sobre la enseñanza, y el papel que debe jugar la EF en el contexto escolar
