    Abstract Understanding if (and how) adults with cancer perceived their physical activity (PA) levels have changed (or not) since the COVID-19 pandemic and why this may have occurred is important. Given current gaps in knowledge, the purpose of this study was to explore PA experiences among adults with cancer amidst the COVID-19 pandemic. Individuals were eligible if they were currently ≥19 years of age, had been diagnosed with cancer ≥18 years of age, and were living in Canada. 113 adults affected by cancer (M

    Abstract Supportive care programming helps many adults affected by cancer manage concerns related to their disease. Public health restrictions imposed by the COVID-19 pandemic have undoubtedly changed the nature of supportive care programming delivery. Yet, access to supportive care programming and comfort gathering through the pandemic are unknown. As a first step towards informing ongoing supportive care programming for adults affected by cancer, this observational, mixed methods study described supportive care programming access through the COVID-19 pandemic and comfort returning to in-person supportive care programming as restrictions eased. Adults affected by cancer (

    Abstract Purpose: Physical activity (PA) after the birth of a child is associated with improved physical and mental health benefits. The aim of the study was to explore new mothers' experiences of PA before and after participation in a group-based PA program for new mothers. The study has three research questions: how new mothers felt; 1) about PA after the birth of their child 2) about engaging in a group-based PA program and 3) after the program ended about ongoing PA engagement.
    Methods: We conducted an 8-week bi-weekly PA program for postpartum women. To understand the experience of postpartum women engaging in a group-based PA program we conducted one-on-one semi-structured interviews before, after, and at 6-month follow-up.
    Results: Of the
    Conclusions: Postpartum women who participated in this group-based PA program had positive benefits to their mental and physical health and were able to alter their PA behaviour.

To understand the experience of postpartum women engaging in a group-based PA program we conducted one-on-one semi-structured interviews before, after, and at 6-month follow-up. Results Of the n = 21 participants in the Moms on the Move study; n = 17 completed pre interviews.s. One primary theme emerged from pre-program interviews where mothers shared how they were lost as to where to start PA. Post-program interviews produced two primary themes; engaging in PA helped mothers, and mothers learned to rethink PA. Conclusions Postpartum women who participated in this group-based PA program had positive benefits to their mental and physical health and were able to alter their PA behaviour.

    Abstract A global pandemic caused by the novel coronavirus (COVID-19) resulted in restrictions to daily living for Canadians, including social distancing and closure of city and provincial recreation facilities, national parks and playgrounds. The objective of this study was to assess how these preemptive measures impacted physical activity behaviour and well-being of Canadians. An online survey was utilized to measure participant physical activity behavior, nature exposure, well-being and anxiety levels. Results indicate that while 40.5% of inactive individuals became less active, only 22.4% of active individuals became less active. Comparatively, 33% of inactive individuals became more active while 40.3% of active individuals became more active. There were significant differences in well-being outcomes in the inactive population between those who were more active, the same or less active (

    Abstract Background: A global pandemic caused by COVID-19 resulted in restrictions to daily living for Canadians, including social distancing and closure of recreation facilities and provincial parks.
    Methods: The objective of this study was to assess whether sex differences exist in physical activity and well-being since COVID-19 and to explore how barriers or facilitators to physical activity may explain these differences. Chi-square tests, independent t-tests and one-way ANOVAs were conducted to evaluate data provided by 1098 Canadians-215 men and 871 women.
    Results: Women were significantly less physically active than men and reported more barriers and fewer facilitators to physical activity and experienced significantly more generalized anxiety than men. Women who were engaged in less physical activity due to COVID-19 reported significantly lower mental health scores, lower social, emotional and psychological well-being, and significantly higher generalized anxiety, while women who engaged in more physical activity had improved mental health scores.
    Conclusions: Given the challenges that women uniquely face due to restrictions, it is imperative to advocate and provide environmental opportunity and support for physical activity to reduce the mental duress women may be experiencing. Specific physical activity programming that is inclusive of lifestyle physical activity and can engage children is encouraged.

    Abstract This study examined muscle activation during the 'push-pull' component of law enforcement physical abilities testing and assessed activation differences based on sex, height, and body mass index. Fifty participants (40 male) completed the 'push-pull' task while surface electromyograms were recorded from ten upper and lower extremity muscles, and six trunk muscles. Muscle activation was amplitude-normalized to maximum voluntary isometric contraction and compared between sexes and tertiles of height and body mass index (BMI). Women had significantly higher activation of anterior deltoid and pectoralis major on the pull, and posterior deltoid and triceps on the push. Significant differences largely remained after controlling for body size in regression analyses. The lowest tertile of height had significantly higher triceps activity on the push. The highest tertile of BMI had significantly higher rectus abdominus and external obliques activity on the pull, and external obliques activation on the push.

    Abstract Physical activity is a beneficial, yet complex, health behavior. To ensure more people experience the benefits of physical activity, we develop and test interventions to promote physical activity and its associated benefits. Nevertheless, we continue to see certain groups of people who choose not to, or are unable to, take part in research, resulting in "recruitment bias." In fact, we (and others) are seemingly missing large segments of people and are doing little to promote physical activity research to equity-deserving populations. So, how can we better address recruitment bias in the physical activity research we conduct? Based on our experience, we have identified 5 broad, interrelated, and applicable strategies to enhance recruitment and engagement within physical activity interventions: (1) gain trust, (2) increase community support and participation, (3) consider alternative approaches and designs, (4) rethink recruitment strategies, and (5) incentivize participants. While we recognize there is still a long way to go, and there are broader community and societal issues underlying recruitment to research, we hope this commentary prompts researchers to consider what they can do to try to address the ever-present limitation of "recruitment bias" and support greater participation among equity-deserving groups.
