20.500.12556/RUL-144769 Secular trends in muscular fitness from 1983 to 2014 among Slovenian children and adolescents Low physical fitness has been found to be associated with many chronic diseases and medical conditions. Knowledge of secular trends in physical fitness is important to initiate countermeasures for addressing negative trends. The aim of this study was to analyze secular trends in health-related muscular fitness in Slovenian children and adolescents between 1983 and 2014. Data were collected as part of “The Analysis of Children's Development in Slovenia (ACDSi)” study in 1983, 1993/94, 2003/04, and 2013/14. Anthropometry (body weight, height, BMI, and triceps skinfold) and muscular fitness (standing long jump, bent-arm hang, and sit-ups 60 s test) of 18730 (9168 female) students from primary and secondary schools were recorded. The secular trend was analyzed considering anthropometry. The results showed that anthropometric measures had an increasing trend and overall muscular fitness had a decreasing trend. Leg muscle power decreased over the decades in all age groups (relative difference between −1.5% and −2.6%), being more pronounced in boys. Arm muscle strength decreased in two younger age groups (range −21.1% to −42.7%, 6–10, and 11–14 years), but not in the oldest group (15–19 years), where the increase occurred in both genders (0.4% to 9.3%). In terms of decades, the largest negative changes (−30.1%) occurred from 1993/94 to 2003/04 and the smallest changes (−4.2%) from 2003/04 to 2013/14. The overall trend in repetitive core strength surprisingly increased (1.1% to 18.3%). There is a need to promote healthy lifestyles, raise parental awareness and use all government resources to redirect the negative trend in physical fitness. sport standing long jump bent-arm hang sit-ups test students ANCOVA children adolescents Slovenia šport telesna dejavnost skok v daljino z mesta vesa v zgibu dviganje trupa šolarji ANCOVA otroci mladostniki Slovenija true false true Angleški jezik Slovenski jezik Članek v reviji 2023-03-10 15:42:38 2023-03-10 15:42:39 2023-03-11 03:36:50 0000-00-00 00:00:00 2021 0 0 Str. 1853-1861 iss. 9 Vol. 31 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 796.01 1600-0838 10.1111/sms.13981 61361923 Scandinavian_Med_Sci_Sports_-_2021_-_uri_-_Secular_trend.pdf Scandinavian_Med_Sci_Sports_-_2021_-_uri_-_Secular_trend.pdf 1 BBCD51F091B96030EC488DD5957C963C 191cb278db575cd5929854b2d4479b5360402de6fbeffa753edaf56779d9616b fb9dacac-bf51-11ed-a314-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=167276 https://onlinelibrary.wiley.com/doi/10.1111/sms.13981 0 dd6ff3ea-bf51-11ed-a314-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=167275 Fakulteta za šport 0 0 0
