The aim was to assess the quality and strength of evidence for the health benefits of specific sport disciplines. Electronic search yielded 2194 records and the selection resulted in 69 eligible studies (47 cross-sectional, 9 cohort, 13 intervention studies). 105 comparisons between participation and non-participation groups in 26 different sport disciplines were reported. Moderately strong evidence showed that both running and football improve aerobic fitness and cardiovascular function at rest, and football reduces adiposity. Conditional evidence showed that running benefits metabolic fitness, adiposity and postural balance, and football improves metabolic fitness, muscular performance, postural balance, and cardiac function. Evidence for health benefits of other sport disciplines was either inconclusive or tenuous. The evidence base for the health benefits of specific sports disciplines is generally compromised by weak study design and quality. Future research should address the health effects of different sport disciplines using rigorous research designs.

Aims: Insufficient physical activity (PA) is one of the largest public health challenges of our time and requires a multisectoral public-health response. PA recommendations state that all children and adolescents should accumulate at least 60 minutes of moderate-to-vigorous PA (MVPA) daily and carry out vigorous PA (VPA) three times weekly. While participation in sports club activities is known to enhance the probability of reaching the recommended overall PA level, less is known about the contribution of sports club participation to VPA, and few cross-national comparisons have been carried out. The purpose of this paper is to study whether participation in sports club activities is associated with meeting the overall PA and VPA recommendations among children and adolescents across six European countries, namely Belgium (Flanders), Czech Republic, Finland, France, Ireland and Sweden. Methods: Analyses were carried out on existing self-reported national data sets using descriptive statistics and logistic regression. Results: Results indicate that approximately two-thirds of children and adolescents take part in sports club activities in the given countries. Sports club participants were more likely to meet the overall PA recommendations (OR 2.4–6.4) and VPA recommendation (OR 2.8–5.0) than non-participants. Conclusions: The extent to which overall PA and/or VPA is gained through sports club participation versus other settings needs to be further studied. Nonetheless, it can be argued that sports clubs have an important position in PA promotion for younger populations.

Background: Several reviews have examined the health benefits of participation in specific sports, such as baseball, cricket, cross-country skiing, cycling, downhill skiing, football, golf, judo, rugby, running and swimming. However, new primary studies on the topic have recently been published, and the respective meta-analytic evidence needs to be updated. Objectives: To systematically review, summarise and appraise evidence on physical health benefits of participation in different recreational sports. Methods: Searches for journal articles were conducted in PubMed/MEDLINE, Scopus, SpoLit, SPORTDiscus, Sports Medicine & Education Index and Web of Science. We included longitudinal and intervention studies investigating physical health outcomes associated with participation in a given sport among generally healthy adults without disability. Results: A total of 136 papers from 76 studies conducted among 2.6 million participants were included in the review. Our meta-analyses of available evidence found that: (1) cycling reduces the risk of coronary heart disease by 16% (pooled hazard ratio [HR] = 0.84; 95% confidence interval [CI]: 0.80, 0.89), all-cause mortality by 21% (HR = 0.79; 95% CI: 0.73, 0.84), cancer mortality by 10% (HR = 0.90; 95% CI: 0.85, 0.96) and cardiovascular mortality by 20% (HR = 0.80; 95% CI: 0.74, 0.86); (2) football has favourable effects on body composition, blood lipids, fasting blood glucose, blood pressure, cardiovascular function at rest, cardiorespiratory fitness and bone strength (p < 0.050); (3) handball has favourable effects on body composition and cardiorespiratory fitness (p < 0.050); (4) running reduces the risk of all-cause mortality by 23% (HR = 0.77; 95% CI: 0.70, 0.85), cancer mortality by 20% (HR = 0.80; 95% CI: 0.72, 0.89) and cardiovascular mortality by 27% (HR = 0.73; 95% CI: 0.57, 0.94) and improves body composition, cardiovascular function at rest and cardiorespiratory fitness (p < 0.010); and (5) swimming reduces the risk of all-cause mortality by 24% (HR = 0.76; 95% CI: 0.63, 0.92) and improves body composition and blood lipids (p < 0.010). Conclusions: A range of physical health benefits are associated with participation in recreational cycling, football, handball, running and swimming. More studies are needed to enable meta-analyses of health benefits of participation in other sports. PROSPERO registration number CRD42021234839.

This paper explores the efficacy and value of sports clubs as a setting for health promotion. Sports clubs for children and adolescents are the primary focus of the paper, and the aims are two-fold. Aims: Firstly, the paper aims to review the basis for and elements of the health promoting sports club (HPSC) concept. Secondly, the aim is to overview the international evolution of the HPSC concept and its usefulness in the research. The settings-based health promotion approach forms the basis for the HPSC concept and it is introduced first. Thereafter, both obligating and prospecting factors, to justify the importance for sports clubs to address health promotion, are expressed. Major prospecting factors relate to the facts that sports club activities reach a lot of children and adolescents, and that its educational nature is informal due to voluntary participation. The paper also presents multilevel structure of sports clubs, as well as the determinants affecting the settings-based work. The research concerning health promotion in sports-related settings is evolving worldwide, and Nordic countries are in the front line of this new-wave of settings-based health promotion. Indeed, it has been claimed that, for the settings approach to assimilate to current societal challenges, there is a need to widen the reach of the approach to non-traditional, non-institutional settings, like sports clubs.

Sports clubs have a long and traditional history in many countries, yet they remain underdeveloped and underutilized settings for health promotion. Leisure time settings, in general, have been in minor role among settings-based health promotion initiatives. Current health concerns in western countries, such as sedentary lifestyles and obesity, have aroused a need to expand health promotion to include also settings with greater potential to reach and engage children and adolescents in more vigorous activity. To develop these alternative, most often non-institutional, settings to the level of the established ones, it is important to review what has been done, what has been accepted and what is known from research, theory and practice to have contributed to health. Given that settings approaches have been implemented with diverse scope and without close cooperation between different initiatives, the first aim of this paper is, on the basis of a review of commonly used theories and practices, to propose a mutual definition for the settings approach to health promotion. The second is to examine the applicability of the theoretical basis to youth sports club settings. Sports clubs are used as a reflective setting when reviewing the traditional ones.

The purpose of this article is, first, to compile a frame of reference for the health promoting sports club and, second, to develop standards for the concept. This concept is based on the settings-based health promotion approach. Sports clubs are a new setting for health promotion, which until now has been little examined from a settings point of view. Nevertheless, this concept has much potential. For example, sports clubs attract a large number of children and adolescents and their educational nature can be considered to be informal. The present standards were developed using the Delphi method. The researcher, in cooperation with a panel of experts (experts in health promotion, n = 11, and experts in sports clubs, n = 16), sought to create a consensus statement on the standards. At the preliminary stage of the study 64 original standards were created on the basis of existing literature and the principles of the Ottawa Charter. During the three rounds of the Delphi process 15 standards were evaluated as the most important. After the Delphi process, the researcher modified the standards by eliminating overlap, interpolating seven standards to involve all strategic areas of the Ottawa Charter and creating a preliminary typology of the standards. At the subsequent stages of the study, indicators for these standards will be drafted and tested in practice. Therefore, this study would provide tools for determining and evaluating how health promoting a particular sports club is.
