One example of such infrastructure is canals and former harbour areas. This paper aims at exploring the underlying factors behind, and the potential benefits and challenges of, recreation- and sport-led regeneration of urban water infrastructure with a focus on former harbours and canals, using three Scandinavian cities as examples: Copenhagen, Gothenburg and Malmö. A conceptual and theoretical frame is built around three perspectives: (1) contemporary trends and tendencies in sport and recreation, and spatial implications thereof, (2) urban regeneration, and (3) recreational spaces as ecosystem services. The empirical material is mainly based on six semi-structured interviews with informants involved in the planning, production and operation of the water infrastructure. As shown by the three examples, there are several benefits of a recreation- and sport-led regeneration of former harbours and canals. Those benefits include, for instance, ecosystem services, such as enhanced biodiversity and improved recreational opportunities, quality of life and well-being, as well as economic benefits in terms of tourism and positive attention. One of the examples also demonstrates that harbour regeneration could be an opportunity to develop methods for community participation and public-nonprofit partnerships. However, the examples highlight a number of challenges as well, such as polluted water and the technical issues and high costs involved in cleaning it; the provision of equal access to the water infrastructure; the creation of a safe co-existence for different actors and activities in the same water space; and diverse ownership, responsibility and regulation issues. To summarize, the paper shows that in a successful recreation-led regeneration of urban water infrastructure, the potential outcome is increased attractivity, activity and sustainability.</p>","PeriodicalId":12716,"journal":{"name":"Frontiers in Sports and Active Living","volume":"7 ","pages":"1558415"},"PeriodicalIF":2.3,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12075216/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144077565","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A systematic literature search of PubMed, Web of Science, and SportDiscus identified studies that examined effects of fatigue in tennis.

It thus can be hypothesized that relatively younger players born at the end of the selection year must mature earlier to compensate for this disadvantage. Hence, this study investigated maturation, relative age, and their association in the talent selection of German youth handball players. A secondary data analysis within an ex post facto design was conducted to examine the birth quarter distributions and maturation parameters of 2,259 female U15 players and 2,340 male U16 players. Practically significant maturation bias was detected in male players, who matured almost one year earlier than common German boys (<i>g</i> = -1.67). This was not evident in female players. Relative age selection biases were observed in female (פ‎ = .16) and male (פ‎ = .20) players. An analysis of maturation timing across birth quarters revealed that relatively younger players born later in the selection year mature earlier than their relatively older peers in both female (<i>g</i> = 0.99) and male players (<i>g</i> = 0.56), thereby partially offsetting relative age disadvantages. Consequently, it may be crucial for relatively younger players to be early-maturing to increase selection odds. Considering the evidence indicating the presence of both maturation and relative age selection biases, it seems prudent to acknowledge the significant impact that these can have on talent selection and development in German youth handball.
