The aim of this review is to provide a scientific update on evidence related to the biological and psycho-social health benefits of physical activity in school-aged children and youth. To accomplish this aim, the first part of the paper reviews existing physical activity guidelines for school-aged children and youth, with an emphasis placed on how Canada’s guidelines compare and contrast with those of other countries and organizations. The paper then provides an overview of physical activity levels of Canadian children and youth, which indicates that few Canadian youngsters meet current physical activity recommendations. The next section of the paper summarizes the literature that informs how much physical activity is required to promote health and well-being in children and youth. The paper then provides suggestions on modifications that could be made to Canada’s physical activity guidelines for children and youth. Specifically, consideration should be given to setting both minimal (≥60 min/d) and optimal (up to several hours per day) physical activity targets. The final section identifies future research needs. In this section, a need is noted for comprehensive dose–response studies of physical activity and health in the paediatric age group

The current low level of physical activity among Canadians is a dominant public health concern. Accordingly, a clear understanding of physical activity patterns and trends is of paramount importance. Irregularities in monitoring, analysis, and reporting procedures create potential confusion among researchers, policy-makers, and the public alike. The purpose of this paper is to consolidate reported findings and provide a critical assessment of the physical activity surveillance procedures, analytical practices, and reporting protocols currently employed in Canada to provide insights for accurate and consistent interpretation of data, as well as recommendations for future surveillance efforts.

The purpose of this paper is to examine the reach of different versions of Canada’s physical activity guide (CPAG) and their impacts, including immediate effects (awareness, knowledge, beliefs, future intention to be active, first steps towards behavioural change) and population levels of physical activity. The analysis is based on eligible adults aged 18 years and older (n = 8,892) included in the 2003 Physical Activity Monitor (PAM) survey. The 2003 PAM was a cross-sectional, telephone interview of a representative population sample. Secular trends of Canadians aged 12 years and older were examined, using representative samples from the National Population Health and Canadian Community Health Surveys. Unprompted recall of any guidelines for physical activity was very low (4%), whereas prompted recall of the CPAG was higher (37%). Unprompted and prompted recall were higher among women and high-income earners, and increased with level of education. Behaviours associated with “seeking information” and “initiating action” were associated with unprompted and prompted recall. Beliefs about the benefits of physical activity and intention to be active were also associated with prompted recall. Unprompted CPAG recall, knowledge about the amount of activity required to meet the CPAG, intention to be active, “seeking information”, and “initiating action” were associated with being “sufficiently active”. The CPAG is an appropriate set of public health guidelines or recommendations around physical activity. The low unprompted recall rate points to the need for a coordinated, well-funded approach to communication of these guidelines, involving governmental and non-governmental partners and intermediaries in municipalities, schools, workplaces, and the recreational, public health, and health-care systems.

Moderate-to-vigorous physical activity (MVPA) is essential for disease prevention and health promotion. Emerging evidence suggests other intensities of physical activity (PA), including light-intensity activity (LPA), may also be important, but there has been no rigorous evaluation of the evidence. The purpose of this systematic review was to examine the relationships between objectively measured PA (total and all intensities) and health indicators in school-aged children and youth. Online databases were searched for peer-reviewed studies that met the a priori inclusion criteria: population (apparently healthy, aged 5–17 years), intervention/exposure/comparator (volumes, durations, frequencies, intensities, and patterns of objectively measured PA), and outcome (body composition, cardiometabolic biomarkers, physical fitness, behavioural conduct/pro-social behaviour, cognition/academic achievement, quality of life/well-being, harms, bone health, motor skill development, psychological distress, self-esteem). Heterogeneity among studies precluded meta-analyses; narrative synthesis was conducted. A total of 162 studies were included (204 171 participants from 31 countries). Overall, total PA was favourably associated with physical, psychological/social, and cognitive health indicators. Relationships were more consistent and robust for higher (e.g., MVPA) versus lower (e.g., LPA) intensity PA. All patterns of activity (sporadic, bouts, continuous) provided benefit. LPA was favourably associated with cardiometabolic biomarkers; data were scarce for other outcomes. These findings continue to support the importance of at least 60 min/day of MVPA for disease prevention and health promotion in children and youth, but also highlight the potential benefits of LPA and total PA. All intensities of PA should be considered in future work aimed at better elucidating the health benefits of PA in children and youth.

Background:Kenya’s 2016 report card aimed to highlight the health and well-being of Kenyan children and youth using the best available evidence on the physical activity of Kenyan children and youth. The report pointed at areas where Kenya was succeeding and areas where more action is required.Methods:Inclusive analyses of available data sources on the core indicators related to physical activity and body weights of Kenyan children and youth (5 to 17 years) were conducted. These were assigned grades based on a set of specific criteria.Results:Results show that Active Play, Active Transportation, Overweight and Obesity, and Sedentary Behavior were favorable with a grade of B. Overall Physical Activity, Organized Sport Participation, and School (infrastructure, policies, and programs) each received a grade of C, while Family and Peers, Government and Nongovernment organizations, as well as the Community and the Built Environment were assigned grade D.Conclusions:Over 72% of Kenyan children and youth use active transportation to and from school and in their daily lives. Although majority of the children and youth have normal body weight, there is need to ensure that they meet and maintain the physical activity levels recommended by the World Health Organization. More needs to be done especially in relation to the governmental and nongovernmental organizations, organized sports participation, as well as involvement of family and peers in promoting healthy active lifestyles among Kenyan children and youth. More representative data for all indicators are required in Kenya.

L’évaluation précise de la quantité d’activité physique pratiquée de façon régulière constitue une donnée fondamentale dans l’étude de la relation entre l’activité physique et la santé. Cependant, plusieurs techniques de mesure de l’activité physique ne donnent que des résultats valables pour une seule journée comme, par exemple, la dépense d’énergie réalisée d’après une auto-évaluation par questionnaire, le nombre de pas fait d’après un podomètre, l’intensité d’activité physique mesurée au moyen d’un accéléromètre comptant le temps à faire des exercices d’intensité modérée à vigoureuse. On peut maintenant utiliser les techniques de monitorage qui informent davantage sur les comportements actifs et sédentaires pour approfondir l’étude de la relation entre la santé et la fréquence, l’intensité et la durée des mouvements accomplis. Cet article présente comment un monitorage objectif, avec une attention particulière portée à l’accélérométrie, peut dresser un bilan d’activité / d’inactivité. Au moyen de données objectives prélevées dans la littérature, on présente un bilan kinésique détaillé et des exemples d’étude de cas incorporant des données et leur interprétation. La quantité d’informations recueillies dans ce profil complet offre de nouvelles avenues de surveillance et d’études scientifiques pouvant déboucher sur de nouvelles directives en matière de pratique de l’activité physique. Nous présentons les résultats de diverses façons pour démontrer les dangers d’une mauvaise interprétation des données quand on évalue une population d’après son taux de conformité aux directives contenues dans le Guide d’activité physique canadien. Nous énonçons des recommandations en matière de profil kinésique / akinésique et nous proposons quelques pistes de recherche.

De nombreuses études épidémiologiques confirment les bienfaits procurés par l’activité physique en ce qui concerne la diminution du risque de maladie associée à l’âge et de la mortalité quelle qu’en soit la cause. L’analyse de la littérature scientifique centrée sur les caractéristiques principales (intensité, type, quantité) montre que la quantité nécessaire d’activité physique est celle qui améliore la condition cardiorespiratoire, la force musculaire, la puissance et, indirectement, l’équilibre. L’appauvrissement de ces fonctions avec l’âge entraîne des limitations physiques qui conditionnent les activités fonctionnelles journalières. En revanche, un programme d’activité physique peut atténuer ces pertes, évitant ainsi aux personnes âgées (plus de 65 ans) de traverser le seuil de l’incapacité physique. Les études transversales et longitudinales révèlent un lien entre la condition cardiorespiratoire et la capacité fonctionnelle et l’autonomie ; la force musculaire et par surcroît, la puissance musculaire, permettent d’accomplir plus efficacement les activités de tous les jours ; l’équilibre dynamique en combinaison avec la puissance musculaire forment un ensemble de prévention contre les chutes. D’après les études sur les programmes d’intervention, les personnes âgées peuvent améliorer leurs capacités fonctionnelles car elles possèdent la capacité d’adaptation à l’entraînement physique. Les quelques études qui ont analysé les quantités minimale et optimale d’activité physique indiquent qu’il faut faire des exercices dans les plages d’intensité modérée à vigoureuse si on veut atteindre et préserver les gains résultant de la pratique régulière. Par conséquent, on devrait prescrire des activités physiques en spécifiant le type d’activité qui améliorera les variables organiques associées au maintien de la capacité fonctionnelle et de l’autonomie et, de ce fait, on repoussera la maladie et la mort. Une bonne recommandation concernant l’exercice physique chez les personnes âgées devrait inclure des activités cardiorespiratoires modérément vigoureuses (la marche rapide), un entraînement à la force et à la puissance pour la préservation de la masse musculaire et de la capacité de travail de groupes musculaires choisis et des exercices d’équilibre et d’étirement au besoin.
