Bone Elongation

Linear growth is the result of bone elongation in children and adolescents mediated by processes of endochondral ossification and maturation of bone tissue. Physical activity (PA) importantly influences both processes through systemic and local effects, mediated by growth hormone, insulin-like factor I, sex hormones, thyroid hormones, glucocorticoid hormones and various cytokines with endo-, para- and autocrine function, secreted by adipose tissue (adipokines) or muscles (myokines). It is important to promote a physically active lifestyle already in early childhood as it tends to persist into adulthood together with favorable body composition. From the safety point-of-view, recent data suggests that PA does not negatively influence linear growth regardless of its duration or intensity, as long as chronic negative energy balance is prevented by sufficient energy intake. The aim of this review is to describe current scientific knowledge on the mechanisms by which PA could influence linear growth and present recent studies analyzing its possible effects.

Wearable Activity Trackers

Wearable activity trackers (wearables) embed numerous behaviour change techniques (BCTs) that have previously been shown to increase adult physical activity (PA). With few children and adolescents achieving PA guidelines, it is crucial to explore ways to increase their PA. This systematic review examined the acceptability, feasibility, and effectiveness of wearables and their potential mechanisms of action for increasing PA in 5 to 19-year-olds. A systematic search of six databases was conducted, including data from the start date of each database to December 2019 (PROSPERO registration: CRD42020164506). Thirty-three studies were included. Most studies (70%) included only adolescents (10 to 19 years). There was some—but largely mixed—evidence that wearables increase steps and moderate-to-vigorous-intensity PA and reduce sedentary behaviour. There were no apparent differences in effectiveness based on the number of BCTs used and between studies using a wearable alone or as part of a multi-component intervention. Qualitative findings suggested wearables increased motivation to be physically active via self-monitoring, goal setting, feedback, and competition. However, children and adolescents reported technical difficulties and a novelty effect when using wearables, which may impact wearables’ long-term use. More rigorous and long-term studies investigating the acceptability, feasibility, and effectiveness of wearables in 5 to 19-year-olds are warranted.

The purpose of this investigation was to determine if a physically active lifestyle affects the health of former football players. Sixty former professional football players aged 40–50 years and who ended their sports career at least ten years ago were recruited for the study and grouped into two groups based on their physical activity habits after their retirement. Health and lifestyle characteristics were collected through a questionnaire to obtain information about recreational physical activity levels, diseases, family medical history, smoking, alcohol intake and dietary habits. Furthermore, lung functions, blood parameters and cardiovascular health were evaluated. Our results showed that body weight and body fat percentage were significantly higher in retired footballers who had a sedentary lifestyle compared to those who were physically active. The absolute and predicted values for forced expiratory volume in one-second values were higher in the active group. Twelve retired athletes were found to have intraventricular conduction delay. The findings suggest that former footballers who have higher levels of physical activity have advanced body composition, respiratory functions and serum lipids compared to former footballers with less active lifestyles. It is recommended that former elite athletes should maintain physically active lifestyles to sustain their health and reduce the risk of disease and disability in the later years of life.

Purpose:The goals were to investigate whether extracurricular school-based sports reach students not engaging in community sports and whether extracurricular school-based sports participants are more physically active and/or autonomously motivated toward sports than nonparticipants.Method:1526 students (48.0% boys; 85.9% Belgian natives; age = 15.34 ± 1.83y) completed validated questionnaires to assess sports participation, physical activity (PA) and sports-motivation. Multilevel regression analyses were conducted.Results:Only 28.7% of all students (n = 438), and 19.7% of students not engaging in community sports (n = 123), participated in extracurricular school-based sports. Participants were significantly more physically active [β=44.19, S.E.=17.34, χ2(1)=6.50, p = .01] and autonomously motivated [β=.18, S.E.=.04, χ2(1)=25.62, p < .001] than nonparticipants, even after controlling for community sports participation. Boys were more physically active and autonomously motivated than girls (p < .001).Conclusion:As participation is linked to higher PA-levels and autonomous motivation, increasing overall participation rates may contribute to children developing a more physically active lifestyle and achieving the PA guidelines.

ObjectivesThe health benefits of professional sport dissipate after retirement unless an active lifestyle is adopted, yet reasons for adopting an active or inactive lifestyle after retirement from sport are poorly understood. Elite cricket is all-encompassing, requiring a high volume of activity and unique physical demands. We aimed to identify influences on physical activity behaviours in active and insufficiently active former elite cricketers and provide practical strategies for promoting physical activity after cricket retirement.Design18 audio-recorded semistructured telephone interviews were performed. An inductive thematic approach was used and coding was iterative and data-driven facilitated by NVivo software. Themes were compared between sufficiently active and insufficiently active participants.SettingAll participants formerly played professional cricket in the UK.ParticipantsParticipants were male, mean age 57±11 (range 34–77) years, participated in professional cricket for 12±7 seasons and retired on average 23±9 years previously. Ten participants (56%) were classified as sufficiently active according to the UK Physical Activity Guidelines (moderate-intensity activity ≥150 min per week or vigorous-intensity activity ≥75 min per week). Eight participants did not meet these guidelines and were classified as insufficiently active.ResultsKey physical activity influences were time constraints, habit formation, intrinsic and extrinsic motivation, physical activity preferences, pain/physical impairment and cricket coaching. Recommendations for optimising physical activity across the lifespan after cricket retirement included; prioritise physical activity, establish a physical activity plan prior to cricket retirement and don’t take a break from physical activity, evaluate sources of physical activity motivation and incorporate into a physical activity plan, find multiple forms of satisfying physical activity that can be adapted to accommodate fluctuations in physical capabilities across the lifespan and coach cricket.ConclusionsPhysically active and less active retired cricketers shared contrasting attributes that informed recommendations for promoting a sustainable, physically active lifestyle after retirement from professional cricket.

Abstract Research shows that, while the experience of stress relates to lower levels of physical activity (PA), people who perceive a greater sense of control engage in higher levels of PA. This study explores whether a sense of control specifically over stressful situations moderates the negative association between stressor exposure and PA in daily life. We used 8-day diary data from up to 1,236 participants (Age: Range = 43-91, M = 62.47, SD = 10.20) in the National Study of Daily Experiences. Somewhat contrary to hypotheses, people reported spending more time on light PA (but not moderate-to-vigorous PA) on days when they also experienced more stressors than usual. Perceived stressor control appears to magnify this effect, with people reporting even more light PA on days when they feel greater control. Initial findings suggest that a physically active lifestyle may help middle-aged and older adults cope with daily stressors.

And Behavior

As technology advances and offers enjoyable sedentary alternatives to sport, active recreation, and transportation, there is a growing need to understand and harness the drivers of physical activity and exercise among children and adolescents. Determining how youth perceive their physical capabilities and their opportunities and what motivates them to be physically active can provide essential information for teachers, coaches, youth leaders, and program planners who are interested in promoting physical activity. Several well-established and also more recently developed behavioral theories offer numerous avenues to gaining a better understanding of the perceptions and motivation of youth with respect to physical activity and exercise behavior, including the social ecological model, social cognitive theory, self-determination theory, habit theory, dual-process theory, and nudge theory, among others. Children and adolescents have individual characteristics that influence their perceptions, motivations, and behavior. They also exist within a multilayered ecological context that helps to shape those perceptions, motivations, and behavior. For youth to be sufficiently physically active and thereby help to reach their full potential, the environment must be conducive to consistent routines of physical activity. Such an environment can be designed to provide easily accessible and enjoyable opportunities for youth to fulfill their basic psychological needs for autonomy, relatedness, and competence to be physically active. There is potential for technology to contribute positively toward the design of conducive environments, and toward fostering motivation and enjoyment of exercise and physical activity among children and adolescents.

Physical activity (PA) is important for the development of children and adolescents with hearing impairments (HI). This systematic review aims to summarise the existing literature pertaining to the PA of children and adolescents with HI. A systematic search was conducted on eight major electronic databases. Two reviewers independently screened and selected the returned articles, performed data extraction, assessed methodological quality and synthesised the data using an inductive approach. A total of 15 articles consisting of 14 survey studies and one single-subject intervention study met the inclusion criteria. These studies had good to excellent methodological quality. Participants with HI showed lower levels of participation in PA than participants without disabilities, but they were more physically active than those with other types of disabilities. Amongst the 12 PA correlates identified (i.e., gender, age, mother’s education and social cognitive constructs), only gender was a relatively consistent determinant, and boys are significantly more physically active than girls. Additional studies are needed to confirm the determinants of the PA in children and adolescents with HI to provide strong evidence for the development and implementation of PA interventions for this target group.

Physically Active

Lack of physical activity is a global public health problem causing not only morbidity and premature mortality, but it is also a major economic burden worldwide. One of the cornerstones of a physically active lifestyle is Motor Competence (MC). MC is a complex biocultural attribute and therefore, its study requires a multi-sectoral, multi-, inter- and transdisciplinary approach. MC is a growing area of research, especially in children and adolescents due to its positive association with a plethora of health and developmental outcomes. Many questions, however, remain to be answered in this field of research, with regard to: (i) Health and Developmental-related Associations of MC; (ii) Assessment of MC; (iii) Prevalence and Trends of MC; (iv) Correlates and Determinants of MC; (v) MC Interventions, and (vi) Translating MC Research into Practice and Policy. This paper presents a narrative review of the literature, summarizing current knowledge, identifying key research gaps and presenting questions for future investigation on MC in children and adolescents. This is a collaborative effort from the International Motor Competence Network (IMCNetwork) a network of academics and researchers aiming to promote international collaborative research and knowledge translation in the expansive field of MC. The knowledge and deliverables generated by addressing and answering the aforementioned research questions on MC presented in this review have the potential to shape the ways in which researchers and practitioners promote MC and physical activity in children and adolescents across the world.
