Lifestyle Behaviors and Needs After Breast Cancer Diagnosis: A Qualitative Assessment.

There is a need to gain a deeper understanding of facilitators and barriers involving lifestyle behaviors among newly diagnosed breast cancer patients. Design: Research team explored influences (e.g., social, cultural, environmental) for healthy lifestyle behaviors (nutrition, physical activity (PA), and self-care). One researcher conducted semi-structured interviews. Qualitative data were analyzed through content analysis. Demographic data were collected via survey, and descriptive statistics were generated. Patients were recruited, and interviews conducted via Zoom or phone. Twenty-eight newly diagnosed, treatment naïve breast cancer patients were interviewed, a majority were non-Hispanic White women (n=23; 82%) with invasive (n=14; 50%) breast cancer. Themes related to nutrition, PA, and self-care emerged, including influences (e.g., environmental, cultural, social), barriers, facilitators, and lived experiences. Most patients stressed the importance of maintaining healthy eating habits (n=23), and some were interested in understanding the relationship between nutrition and cancer (n=7). Sixteen reported sustaining their PA levels, while others (n=11) explained barriers, such as time, distance, and pain. All patients reported utilizing self-care strategies, and most reported increased engagement in self-care since being diagnosed (n=14). This study sheds light on factors influencing and hindering the adoption of healthy eating, PA, and self-care strategies among newly diagnosed breast cancer patients. The findings reflect the importance of healthy lifestyle behaviors as critical areas for upstream intervention.

The contribution and interplay of implicit and explicit processes on physical activity behavior: empirical testing of the physical activity adoption and maintenance (PAAM) model

The adoption and maintenance of physical activity (PA) is an important health behavior. This paper presents the first comprehensive empirical test of the Physical Activity Adoption and Maintenance (PAAM) model, which proposes that a combination of explicit (e.g., intention) and implicit (e.g., habit,, affect) self-regulatory processes is involved in PA adoption and maintenance. Data were collected via online questionnaires in English, German, and Italian at two measurement points four weeks apart. The study included 422 participants (Mage= 25.3, SDage= 10.1; 74.2% women) from Germany, Switzerland, Italy, Canada, and the U.S. The study results largely supported the assumptions of the PAAM model, indicating that intentions and habits significantly mediate the effects of past PA on future PA. In addition, the effect of past PA on future PA was shown to be significant through a mediation chain involving affect and habit. Although the hypothesis that trait self-regulation moderates the intention-behavior relationship was not supported, a significant moderating effect of affect on the same relationship was observed. The results suggest that interventions targeting both explicit and implicit processes may be effective in promoting PA adoption and maintenance.

Physical Activity, Long-COVID, and Inactivity: A Detrimental Endless Loop.

The risk of developing medium- and long-term sequelae after recovery from COVID-19 is validated. Long-COVID burden represents a major health care issue, thus paving the way to effective prevention and/or treatment measures. Physical activity prevents many human pathologies, including COVID-19. Being physically active before and immediately after a severe acute respiratory syndrome coronavirus 2 infection substantially lowers the risk of developing long-COVID. In addition, long-COVID is an important cause of physical inactivity. Physically inactive individuals are at increased risk of developing long-COVID, while patients with long-COVID are more likely to reduce their physical activity levels after recovering from the acute infection, with the risk of generating a continuous loop. This harmful interaction needs to be recognized by public health institutions, and the adoption of physical activity as a routine clinical practice in all individuals after a severe acute respiratory syndrome coronavirus 2 infection needs to be proactively promoted.

Physical Activity and Fatigue Symptoms: Neurotypical Adults and People with Chronic Multisymptom Illnesses.

For neurotypical adults, a single bout of low-to-moderate intensity physical activity usually transiently improves feelings of energy. Similar bouts of exercise have the opposite effect of increased feelings of fatigue when performed by samples with chronic multisymptom illnesses (CMIs) such as Long-COVID, Gulf War Illness (GWI), or Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS). The short-term adoption of regular moderate intensity physical activity (typical experiments are 1 to 6months) among neurotypical adults results in small-to-moderate improvements in self-reported feelings of fatigue, energy, and vitality. Small improvements in these feelings, or no change at all, occur for CMIs, but limited data precludes strong conclusions. The mechanisms of exercise effects on fatigue, whether acute or chronic, are poorly understood but likely involve multiple neural circuits and associated transmitters. For CMIs, the mechanisms of acute worsening of fatigue with exercise may be driven by the yet unknown pathophysiological mechanisms of the disease (perhaps involving brain, immune and autonomic system dysfunction, and their interactions). Likewise, fatigue improvements may depend on whether chronic physical activity is a disease-modifying treatment.

Effectiveness of m-health technology-enabled physical activity program on physical activity adoption and adherence in people with hypertension in India: A randomized controlled trial protocol.

Exercise and medication have similar benefits in reducing blood pressure (BP); however, hypertension management initiatives primarily focus on medicines. This is due to scarce research on the effectiveness of implementation strategies for optimal exercise adoption and adherence. Smartphones were found to be effective in delivering hypertension care and increase exercise adherence. Despite this, only a small number of research projects in India have used smartphones as a strategy for managing hypertension. We hypothesized that smartphone application-based care would lead to higher exercise adherence among adults (30-79 years) with hypertension compared to those who receive usual care. It will be a multicentric, randomized controlled, parallel-design, superiority clinical trial. The outcome assessor and data analyst will be blinded to group allocation. Participants in the intervention group will receive mobile application-based care for 6 weeks. Participants in the usual care group will receive a standard intervention. Both groups will receive the same number of follow-ups. The primary outcome is the difference in the proportion of people adherent to the recommended level of physical activity evaluated using an exercise adherence rating scale in the intervention group and the control group. Exercise adoption will be measured as the percentage of eligible participants in each study setting willing to initiate the exercise program. The secondary outcome includes differences in systolic and diastolic BP and self-management (evaluated using the Hypertension Self-Care Profile). The trial outcome will be accompanied by a process evaluation. This research will inform about the comparative effectiveness of conventional and m-health interventions for exercise adoption and adherence in people with hypertension in resource-constrained settings.

Just Run: Development of a theory-based motivational online intervention for promoting ongoing running participation

Running is a popular form of physical activity yet discontinuation is common. Interventions targeting physical activity adoption have shown modest effects, often with little translation into long-term participation, which may limit the health benefits available to the wider community. This paper details the development of a new online running intervention (Just Run) aimed at improving continuation of running activity in new runners through a motivational and psychological lens, including aspects of design, content, refinement, and usability testing. A six-step intervention mapping process was used to develop a theory-based online intervention using a mix of research designs. Key stakeholders including runners, coaches and relevant experts in physical activity and behavior change provided valuable insight, feedback and refinement of the education to be delivered. The final Just Run intervention included ten modules delivered online over twelve weeks to promote ongoing running participation through videos, testimonials, and activities. Key themes identified through the literature and stakeholder engagement process related to goal setting, self-efficacy, intrinsic motivation, social support and overcoming barriers to running participation. Usability testing confirmed the quality and suitability of the education to the target population. Just Run has been developed with a range of stakeholders to address an area of unmet need in the adoption and promotion of running. Just Run is a robust online intervention that has been designed and pre-tested with positive feedback and unique insights from key stakeholders. Further investigation is required to support its implementation to the wider community.

Older adults participation and adoption among a lifestyle‐based multidomain dementia prevention program

AbstractBackgroundOlder adult participation in lifestyle‐based programs has been described round 80%. (Lee et al., 2018). Participation at dementia prevention programs has been influenced by age, gender, marital status, and interest in receiving health education (Coley et al., 2021). The aim of this study is to evaluate the participation and adoption of lifestyle changes of older adults in a multidomain dementia prevention program from the LatAm Fingers Initiative, in MexicoMethodhealthy cognitive older adults between 60 to 77 years old were recruited. 148 pre‐screenings were done to complete a 100 participants sample, all of them were randomized between Systematic (SIG) (supervised participation) or Flexible FIG (educational advises) Lifestyle Intervention groups (50 per group). Participation is defined as attendance to educational session for physical, nutritional, cognitive and cardiovascular health plus attendance to physical activities, diary diet delivery, and 48 levels per week of cognitive online activities through 6‐months. Participation was classified as low, moderate, and high.ResultMean age was 70.06 (±5.4) years old, and 70.8% participants were females. From 48 participants of the systematic group (SIG) there were two dropouts because problems for traveling, and work. 45% of the SIG, are participating on the four intervention domains. 40 participants are currently at the physical activity intervention. From them high participation and adoption of physical activity was 52.5%, moderate participation was 37.5% and low, 10%. From Nutritional intervention are 26 participants who showed high participation at 57.7%, 11.5% moderate and 30.8%, low. The 21 participants that are at the Cognitive intervention stage, 33.3% had high participation, 52.4% moderate and 14.3% low participation. From the 18 participants at the health intervention stage, 94.4% participants had high participation and 5.6% low.Conclusionfrom this preliminary data, we found that the in the SIG the participation rates, are moderate to high. Physical, nutritional, and cardiovascular health activities showed more than 50% of participation rate. Also, nutritional domain showed the lowest percentage of participation among the four interventions.

Effects of mindful physical activity on perceived exercise exertion and other physiological and psychological responses: results from a within-subjects, counter-balanced study.

Most adults are insufficiently active. Mindfulness training may increase moderate to vigorous physical activity (MVPA) adoption and adherence. However, physiological and psychological factors underlying these effects are not well understood. This study examined the effects of an acute bout of MVPA, mindfulness training, and combined MVPA and mindfulness training on physiological and psychological outcomes. Healthy adults (N = 29, Mage = 28.6) completed 20-min counterbalanced conditions: (a) mindfulness training (MIND); (b) moderate intensity walking (PA), and (c) moderate intensity walking while listening to MVPA-specific guided mindfulness training (PAMIND). Heart rate (HR), Rating of Perceived Exertion (RPE), Feeling Scale (FS) and Blood Pressure (BP) were measured at rest, at regular intervals during each condition, and post-condition. Mindfulness, state anxiety, and self-efficacy were assessed pre- and post-condition. Average and peak HR, systolic BP (SBP), and RPE were significantly higher, and average and peak FS were significantly lower during the PA and PAMIND conditions compared to MIND (p < 0.001). Average RPE was significantly higher for PA compared to PAMIND (p < 0.001). Heart rate, feeling scale, body and mental events mindfulness, and self-efficacy for walking increased from pre to post (all p's < 0.001) for all conditions. Time by condition interactions were significant for change in heart rate, mental events mindfulness, and state anxiety from pre- to post-condition. The physiological response to MVPA and PAMIND were similar. However, RPE was rated lower in the PAMIND condition, which could have implications for MVPA adoption and maintenance. Future work should further explore RPE combining MVPA and mindfulness training.

Sociodemographic Barriers to Physical Activity and Healthy Diet Through Social Networks in Mexican Breast Cancer Survivors.

Introduction Female breast cancer (BC) survivors are affected by poor eating habits and physical inactivity due to certain environmental, physical, and social barriers to healthy lifestyles. This study aimed to identify the sociodemographic, physical, and economic barriers hindering the adoption of physical activity (PA) and a healthy diet, as well as providing insights into how BC survivors cope with these barriers using social networks. Methods A cross-sectionalmixed-methods study was conducted, with a self-administered questionnaire and open-ended questions to determine the barriers to PA and healthy eating, while in the second phase, an interpretive qualitative study was carried out with semi-structured interviews. Descriptive statistics, odds ratios (ORs), correspondence analysis, and multivariate analysis were used to estimate the association between moderate to vigorous PA and fruit and vegetable consumption and BC covariates. Results During the COVID-19 lockdown, 150 Mexican BC survivors were studied. The multivariate analysis showed that age (OR = 2.7, 95% CI: 1.0 to 7.03), socioeconomic level (OR = 3.2, 95% CI: 1.3 to 8.2), and overweight (OR = 3.6, 95% CI: 1.5 to 9.7) were significantly associated with low schooling. BC diagnosis of less than three years and age > 40 years were associated with lack of exercise. Survivors individually addressed the challenges associated with BC without the support of specialists. As a result, they sought information on social networks. Conclusions Regarding BC survivors, age > 40 years, low socioeconomic status, and being overweight were important gaps to PA and a healthy diet. In the testimonials, the primary obstacle to engaging in PA was lack of time, while the high cost of food was the most frequently cited reason for not following a healthy diet. Many of the individuals maintained a poor diet with a low intake of fruits and vegetables. Thus, appropriate information must be provided using technologies to develop skills to deal with BC.

Enabling mothers of young children in a low SES area to co-design the support they are seeking for the adoption of healthy behaviours.

There is a need for interventions that meet the needs of low socioeconomic status (SES) groups, to encourage the adoption of healthy diets and physical activity, in line with current public health guidance. This qualitative research used co-production, a method which actively involves the relevant community, to identify and describe public health interventions to support a group of mothers of young children living in a low SES area. A group of 20 mothers took part in three in-depth qualitative interviews to discuss in detail the type of support that would be of value to them for the adoption and maintenance of healthy behaviours. The mothers were subsequently invited to take part in a public engagement project, a community-based self-help group. Four themes explained the principles of interventions that would be of value in supporting the mothers with the adoption of healthy behaviours, namely, a community-based self-help group, support for the whole family and support in the home and influencing the environment. These were then further developed into two types of intervention (1) learning for self-help and family care, which encompassed the first three learning-based themes and (2) community of support, which covered influencing the environment and the experience of the community-based self-help group. Co-production enabled a group of mothers of young children, from a low SES area, to describe the type of support that would help them with the establishment and maintenance of healthy lifestyle behaviours. A community-based self-help group warrants further research.

O.6.3-5 A national audit into the different levels of typical school provision of physical education, physical activity and sports in the Republic of Ireland

Abstract International guidelines recommend sixty-minutes of moderate-to-vigorous-intensity physical activity (PA) daily for adolescents (WHO, 2020). Prevalence of physical inactivity is high and is regarded as a leading risk factor for death worldwide, contributing to the onset of non-communicable diseases with just 20% of adolescents meeting the recommended PA guidelines (Guthold et al., 2020). Physical inactivity cost $67.5 billion worldwide in 2013 and is estimated to reach over €110 billion in 2030 (WHO, 2022). Despite the worldwide adoption of school PE, PA and sport policies to promote PA and health, paralleled with significant investment, a gap in the literature exists that audits the different levels of typical school provision of PE, PA and sports. Participating schools (n = 112) completed the validated PE, PA and sports provision evaluation index. A One-way ANOVA with Tukey Kramer's Post-Hoc test was performed to examine variation in the demographic profile relative to the indicators of provision. A proposed grade for each indicator of provision was established using a standardized, international grading system. Half of schools had no outdoor all-weather surface (54.5%). Two thirds had no facilities to accommodate active transport (66.1%). One in five felt the percentage of the budget given towards PE, PA and sports was inadequate (19.6%). Regarding indicators of provision, partnerships received the lowest grade (C-) while facilities and equipment received the highest grade (B-). Provision scores for personnel were significantly higher for mixed schools (girls/boys) in comparison to girls schools. Provision scores for budget and partnerships were significantly higher for larger schools (&amp;gt;800) then small schools (&amp;lt;300). The evidence suggests that while there has been a significant shift in focus both in policy development and the availability of financial resources to enhance typical school provision of PE, PA and sports for adolescent health, considerable modification of existing provision is required to potentiate positive impact.

Is The Maintenance Or Adoption Of Physical Activity Associated With Cardiometabolic Risk Reduction Among Young Adults With Overweight And Obesity?

Is The Maintenance Or Adoption Of Physical Activity Associated With Cardiometabolic Risk Reduction Among Young Adults With Overweight And Obesity?

Studying Movement-Related Behavioral Maintenance and Adoption in Real Time: Protocol for an Intensive Ecological Momentary Assessment Study Among Older Adults.

Older adults struggle to maintain newly initiated levels of physical activity (PA) or sedentary behavior (SB) and often regress to baseline levels over time. This is partly because health behavior theories that inform interventions rarely address how the changing contexts of daily life influence the processes regulating PA and SB or how those processes differ across the behavior change continuum. Few studies have focused on motivational processes that regulate the dynamic nature of PA and SB adoption and maintenance on microtimescales (ie, across minutes, hours, or days). The overarching goal of Project Studying Maintenance and Adoption in Real Time (SMART) is to determine the motivational processes that regulate behavioral adoption versus maintenance over microtimescales, using a dual process framework combined with ecological momentary assessment and sensor-based monitoring of behavior. This paper describes the recruitment, enrollment, data collection, and analytics protocols for Project SMART. In Project SMART, older adults engaging in at least 30 minutes of moderate-to-vigorous intensity PA per week complete 3 data collection periods over 1 year, with each data collection period lasting 14 days. Across each data collection period, participants wear an ActiGraph GT3X accelerometer (ActiGraph, LLC) on their nondominant waist and an ActivPAL micro4 accelerometer (PAL Technologies, Ltd) on their anterior thigh to measure PA and SB, respectively. Ecological momentary assessment questionnaires are randomly delivered via smartphone 10 times per day on 4 selected days in each data collection period and assess reflective processes (eg, evaluating one's efficacy and exerting self-control) and reactive processes (eg, contextual cues) within the dual process framework. At the beginning and end of each data collection period, participants complete a computer-based questionnaire to learn more about their typical motivation for PA and SB, physical and mental health, and life events over the course of the study. Recruitment and enrollment began in January 2021; enrollment in the first data collection period was completed by February 2022; and all participants completed their second and third data collection by July 2022 and December 2022, respectively. Data were collected from 202 older adults during the first data collection period, with approximate retention rates of 90.1% (n=182) during the second data collection period and 88.1% (n=178) during the third data collection period. Multilevel models and mixed-effects location scale modeling will be used to evaluate the study aims. Project SMART seeks to predict and model the adoption and maintenance of optimal levels of PA and SB among older adults. In turn, this will inform the future delivery of personalized intervention content under conditions where the content will be most effective to promote sustained behavior change among older adults.

Testing Assumptions of the Physical Activity Adoption and Maintenance Model: A Longitudinal Perspective of the Relationships Between Intentions and Habits on Exercise Adherence.

In this study, we aimed to examine empirically the Physical Activity Adoption and Maintenance model (PAAM). We collected data on these variables at baseline (T0) and 6-months later (T1). We recruited 119 participants (42 male, 77 female) aged 18-81years old (Mage = 44.89, SD = 12.95). who reported, at baseline, that they exercised an average of 3.76days per week (SD = 1.33) in training periods lasting 15-60minutes (M = 38.69; SD = 23.28). We conducted hierarchical multiple regression analysis to test the association between each determinant (intentions, habits, and frequency) and future exercise adherence. We tested four models by entering blocks of predictors according to PAAM assumptions. The variance change (R2) between the first and fourth models (ΔR2 = .391) was statistically significant, showing that the fourth model accounted for 51.2% of variance for future exercise adherence, F (6, 112) = 21.631, p < .001, R2 = .73, adjusted R2 = .512. Exercise intention at T1 maintained its significant association (p = .021) with exercise frequency at T1 in all tested models. Exercise frequency at T0 was the most significant predictor (p < .01) of future exercise adherence, with past experience the second most significant predictor (p = .013). Interestingly, exercise habits at T1 and T0 did not predict exercise frequency at T1 in the fourth model. Among the variables we studied, having constantly high exercise intentions and high regular exercise frequency are significantly associated with maintaining or increasing regular future exercise behavior.

Promoting physical activity through supervised vs motivational behavior change interventions in breast cancer survivors on aromatase inhibitors (PAC-WOMAN): protocol for a 3-arm pragmatic randomized controlled trial

BackgroundAromatase inhibitors (AI) are frequently used to treat hormone-receptor-positive breast cancer, but they have multiple adverse effects (e.g., osteoporosis, arthralgia), resulting in premature therapy discontinuation/switch. Physical activity (PA) can attenuate these negative effects and improve quality of life (QoL). However, most cancer survivors fail to perform/sustain adequate PA levels, especially in the long-term. Theory-based interventions, using evidence-based behavior change techniques, aimed at promoting long-term behavior change in breast cancer survivors are effective, but remain scarce and fail to promote self-regulatory skills and better-quality motivations associated with sustained PA adoption. This paper describes the design of the PAC-WOMAN trial, which will test the long-term effectiveness and cost-effectiveness of two state of the art, group-based interventions encouraging sustained changes in PA, sedentary behavior, and QoL. Additional aims include examining the impact of both interventions on secondary outcomes (e.g., body composition, physical function), and key moderators/mediators of short and long-term changes in primary outcomes.MethodsA 3-arm pragmatic randomized controlled trial, involving a 4-month intervention and a 12-month follow-up, will be implemented, in a real exercise setting, to compare: 1) brief PA counseling/motivational intervention; 2) structured exercise program vs. waiting-list control group. Study recruitment goal is 122 hormone-receptor-positive breast cancer survivors (stage I-III), on AI therapy (post-primary treatment completion) ≥ 1 month, ECOG 0–1. Outcome measures will be obtained at baseline, 4 months (i.e., post-intervention), 10 and 16 months. Process evaluation, analyzing implementation determinants, will also be conducted.DiscussionPAC-WOMAN is expected to have a relevant impact on participants PA and QoL and provide insights for the improvement of interventions designed to promote sustained adherence to active lifestyle behaviors, facilitating its translation to community settings.Trial registrationApril 20, 2023 – NCT05860621.April 21, 2023 – https://doi.org/10.17605/OSF.IO/ZAQ9NApril 27, 2023 – UMIN000050945.

Exergaming Characteristics in Interventions Addressing Physical Activity and Nutrition: A Systematic Literature Review

INTRODUCTION: The increasing popularity of exergames to promote the adoption of physical activity and healthy nutrition among different population groups is well established. However, due to the use of various types of exergames, their effectiveness in addressing specific behaviours varies.OBJECTIVES: This systematic review aims to identify, classify exergaming elements, and examine their efficacy in enhancing physical activity levels, improve nutrition habits, or a combination of both, across various populations.METHODS: A systematic search was conducted to identify relevant publications. Data on study characteristics pertaining to types of exergames, purpose, focus, target population, technologies used, and the theoretical framework were extracted. A classification scheme of exergaming components and characteristics has been developed to facilitate this systematic review.RESULTS: A total of 34 studies were included and n=21 of them were experimental. Most studies (n=31) were focused on Physical Activity using exergames, whereas n=9 studies addressed both Physical Activity and Nutrition simultaneously.CONCLUSION: All of the studies reported positive behavioural outcomes, although, prolonged and sustained engagement with exergames were not consistently reported.

Which Intervention Strategies Promote the Adoption and Maintenance of Physical Activity? Evidence From Behavioral Trials With Cancer Survivors.

We address four questions about interventions to promote physical activity in cancer survivors: (a) How often is both the adoption and maintenance of behavior change tested in trials? (b) How often do interventions generate adoption-plus-maintenance of behavior change? (c) Are intervention strategies specifically geared at promoting maintenance of behavior change deployed in trials? and (d) Which intervention strategies distinguish trials that promote both the adoption and maintenance of physical activity from trials that promote adoption-only or generate no behavioral changes? Computerized literature searches identified 206 reports of randomized trials that measured physical activity in the wake of the intervention. Only 51 reports (24%) measured both behavioral adoption (postintervention) and behavioral maintenance (≥3 months follow-up). The 51 reports included 58 tests of interventions; 22% of tests observed both adoption and maintenance of physical activity, 26% reported adoption-only, and 52% found no change in behavior. Change techniques designed to promote behavioral maintenance were used much less frequently than adoption techniques or adoption and maintenance techniques. Interventions that aimed to improve quality of life, used supervised exercise sessions, were undertaken in community centers, and deployed fewer behavior change techniques were associated with adoption-plus-maintenance of physical activity in cancer survivors. The present findings offer new insights into the adoption and maintenance of physical activity and highlight the need to routinely assess these forms of behavior change in future trials. More extensive testing of intervention strategies specifically geared at maintenance of behavior change is warranted.

Trends in physical activity in adolescents participating and not participating in organized team or individual physical activity.

Participation of adolescents in organized physical activity (PA), together with physical education, is essential for the development of a habit of regular PA, achievement of PA recommendations and adoption of physical literacy. The aim of the study is to identify the trends and differences in PA levels between adolescents participating in organized team PA, organized individual PA, and those not participating in organized PA. Another aim is to formulate proposals to eliminate the negative effects of the pandemic on adolescents' participation in organized PA. The research took place between 2012-2021 in 51 secondary schools and involved a total of 1,202 boys and 1,561 girls. Participation in organized PA was examined using the 'Sports preferences survey'. Weekly PA was investigated by means of the 'International Physical Activity Questionnaire-Long Form'. The results confirmed the negative trend in participation in organized PA. However, this was predominantly caused by the negative effects of the pandemic in 2020-2021. Boys participating in organized team and individual PA had more school PA, recreation PA, vigorous PA, moderate PA and overall PA during the week, compared with boys not participating in organized PA (girls had more vigorous PA, moderate PA and overall PA). Participation in organized team PA and individual PA plays an important role, primarily in supporting vigorous PA but also in overall weekly PA among boys and girls. The negative effects of the pandemic should be eliminated by increasing adolescents' participation in various forms of organized PA with an emphasis on organized individual PA which can be regularly pursued, even under restrictive measures at home, in the countryside or in nature.
