Background: More moderate to vigorous physical activity (MVPA) and less time in sedentary behavior (SB) may protect against poor mental health in adolescence. Depressive symptomatology may also influence adolescents’ own MVPA and SB. The aim of this study was to examine the bidirectional relationship between adolescent MVPA, SB, and depressive symptomatology using a longitudinal approach. Methods: Adolescents (10–16 y) were recruited for a prospective observational cohort. Depressive symptomatology was measured using the Short Mood and Feelings Questionnaire. Accelerometry was used to measure MVPA and SB. Adolescents were classified by meeting the MVPA guideline (≥60 min/d) and quartiles of SB time, with the lowest amount of time in SB compared to others. Bidirectional associations between MVPA, SB, and depressive symptomatology were assessed using mixed-effects regression models. Results: At baseline, adolescents (n = 205) were 12.5 (2.0) years, 54.6% women, 59.1% White, and 34.6% African American. In unadjusted models, adolescents with less baseline time in SB had lower follow-up Short Mood and Feelings Questionnaire scores, and fewer were classified as depressed at follow-up compared to others. After adjustment, adolescents with less baseline time in SB had lower depressive symptomatology at follow-up. Conclusions: Limiting time spent in SB in adolescence may improve future mental health.

This paper examines the tenuous balance of Indigenous generosity in hockey spaces with the need for non-Indigenous players and organizers to educate themselves and others, pursue systemic change, and unburden Indigenous players of the heavy lifting of anti-racism. Interviews with five Indigenous elite women’s hockey players identify hockey as a potential site of decolonial and anti-racist learning, fueled by the players’ love for the game and willingness to expend emotional labor to affect change. Our interviewees express the desire to make hockey safer for future generations of Indigenous players by educating their non-Indigenous teammates, often, in the process, exposing themselves to ignorance, indifference, and racism. The players uniformly argue that education is required for change; however, this paper illustrates that such education is not solely the responsibility of Indigenous participants in the game.

Accelerometer technology and applications have expanded and evolved rapidly over approximately the past two decades. This commentary, which reflects content presented at a keynote presentation at 8th International Conference on Ambulatory Monitoring of Physical Activity and Movement (ICAMPAM 2022), discusses aspects of this evolution from the author’s perspective. The goal is to provide historical context for newer investigators working with device-based measures of physical activity. The presentation includes discussion of the fielding of accelerometer devices in the 2003–2006 National Health and Nutrition Examination Survey, selected recommendations from relevant workshops between 2004 and 2010, and the author’s perspective on the current status of accelerometer use in population surveillance and public health. The important role of collaboration is emphasized.

Background: To determine the effect of resistance training volume on physical and perceptual outcomes of breast cancer survivors submitted to a combined training program. Design: Randomized single-blinded study. Methods: Nineteen breast cancer survivor women were randomized to a single-set (SS) or a multiple-set (MS) group. Both groups completed an 8-week combined training intervention in which the SS and MS groups performed 1 and 3 sets per resistance exercise, respectively. The following outcomes were assessed preintervention and postintervention: maximal knee extension dynamic strength (1-repetition maximum), quadriceps muscle thickness, peak oxygen uptake, time to exhaustion, cancer-related fatigue, and quality of life. Results: Both interventions increased knee extension 1-repetition maximum (SS: 29.8% [37.5%]; MS: 19.3% [11.8%]), quadriceps muscle thickness (9.4% [4.1%]; 8.9% [5.9%]), and quality of life (4.3% [6.3%]; 7.9% [9.0%]), with no difference between the groups. However, only MS improved cancer-related fatigue (−2.1% [1.7%]) and time to exhaustion (21.3% [14.9%]), whereas peak oxygen uptake remained unchanged in both groups. Conclusions: Cancer-related fatigue and time to exhaustion, improved only in the MS group after the intervention. On the other hand, similar knee extension 1-repetition maximum, quadriceps muscle thickness, and quality of life improvements were observed in breast cancer survivors irrespective of the resistance training volume performed.

We strongly believe that diversity, equity, and inclusion in research lead to better science, more innovations and more relevant outcomes that better serve society at large. Historically, scientific research is quite WEIRD, meaning that it is dominated by researchers and study samples from Western, Educated, Industrialized, Rich, and Democratic countries. Such WEIRD research leads to results that better serve a small, privileged group of WEIRD people, widening health inequalities. Research among a selective group with similar backgrounds and perspectives results in bias and hinders innovation. As a result, we end up missing out on the valuable holistic viewpoint that more inclusive research would gain. In this invited commentary based on the International Conference on Ambulatory Monitoring of Physical Activity and Movement (ICAMPAM) 2022 keynote presentation by Prof. ChinAPaw, we discuss the importance of diversity, equity, and inclusion in research and introduce our vision for AWESOME science—All-inclusive, Worldwide ranging, Equitable, Sincere, Open-minded, Mindful of our own implicit bias, and Essential—that is more inclusive and relevant for everyone regardless of who they are and where they live. More diversity, equity, and inclusion make our collective dance toward healthy societies more beautiful and impactful!

Background: A low socioeconomic status (SES) presents lower physical activity; however, the relationship between SES and sedentary behavior (SB) remains unclear. We aimed to assess this association of SES with physical activity (PA) and SB. Methods: We employed representative self-reported data of the European Union from the cross-sectional survey Eurobarometer 2017, comprising a final sample of 13,708 citizens (18–64 y old), to assess the association of SES (education, occupation, and economic issues) with PA and sitting time quartiles, and to describe inequalities in vigorous, moderate, and walking activity and sitting time. Results: Multinomial regressions revealed that people from higher SESs were more likely to report higher PA; nonetheless, higher educational attainment and occupations were also associated with higher sitting time but not with lower economic issues. The inequality, shown by Gini coefficients, describes a socioeconomic gradient in vigorous and moderate activity, from higher inequality in lower statuses to lower inequality in higher statuses. The Gini coefficients also indicated higher socioeconomic inequalities in PA than SB. Conclusions: Higher SESs showed paradoxically more PA and SB; however, sitting time presented smaller differences and a more homogeneous distribution across the population.
