20.500.12556/RUL-190779 Vpliv količine telesne (ne)dejavnosti na sestavo telesa in srčno-dihalno zmogljivost mladostnikov The impact of the amount of physical (in)activity on body composition and cardiorespiratory fitness in adolescents V naši raziskavi smo ugotavljali ali je količina telesne nedejavnosti močneje povezana s telesno sestavo in srčno-dihalno zmogljivostjo mladostnikov kot količina zmerne do visoko intenzivne telesne dejavnosti. V raziskavo je bilo vključenih 2017 mladostnikov iz slovenskih osnovnih in srednjih šol, starih med 12 in 19 let, podatki pa so bili pridobljeni v okviru raziskave ARTOS (Analiza razvojnih trendov otrok v Sloveniji) 2023 in 2024. Za oceno zmerne do visoko intenzivne telesne dejavnosti smo uporabili vprašalnik SHAPES, količino telesne nedejavnosti pa ocenili kot skupni čas, preživet v posameznih oblikah sedečega vedenja. Za izračun telesne sestave smo uporabili rezultate antropometričnih meritev. Indeks telesne mase smo izračunali iz telesne višine in telesne mase, odstotek telesne maščobe smo ocenili iz rezultatov meritev kožnih gub, abdominalno debelost pa z obsegom pasu. Za izračun srčno-dihalne zmogljivosti smo uporabili podatke, pridobljene pri 20-metrskem stopnjevalnem teku. Za analizo podatkov smo uporabili primerne statistične analize. Rezultati so pokazali, da je količina zmerne do visoko intenzivne telesne dejavnosti močneje povezana z antropometričnimi značilnostmi (indeksom telesne mase) ter srčno-dihalno zmogljivostjo, kot količina telesne nedejavnosti. Ugotovili pa smo, da je telesna nedejavnost neodvisno povezana s srčno-dihalno zmogljivostjo mladostnikov. V skupini mladostnikov, ki dosega priporočila za telesno dejavnost, so imeli mladostniki z nizko količino telesne nedejavnosti statistično značilno višjo srčno-dihalno zmogljivost od vrstnikov z visoko količino telesne nedejavnosti. Na podlagi teh ugotovitev zaključujemo, da je pomembno razvijati preventivne ukrepe, ki mlade spodbujajo ne le k doseganju zadostne količine zmerne do visoko intenzivne telesne dejavnosti, temveč tudi k zmanjševanju časa, preživetega v različnih oblikah sedečega vedenja. In our study, we investigated whether the amount of physical inactivity was more strongly associated with body composition and cardiorespiratory fitness in adolescents than the amount of physical activity. The study included 2017 adolescents aged 12 to 19 years from Slovenian primary and secondary schools. Data were obtained as part of the ARTOS (Analysis of Children's Developmental Trends in Slovenia) study conducted in 2023 and 2024. Moderate-to-vigorous physical activity was assessed using the SHAPES questionnaire, while physical inactivity was estimated as the total time spent engaging in different forms of sedentary behaviour. Body composition was assessed using anthropometric measurements. Body mass index was calculated from height and body mass, body fat percentage was estimated from skinfold measurements, and abdominal obesity was assessed using waist circumference. Cardiorespiratory fitness was assessed using data obtained from the 20-metre shuttle run test. Appropriate statistical analyses were performed to analyse the data. The results showed that moderate-to-vigorous physical activity was more strongly associated with anthropometric characteristics (body mass index) and cardiorespiratory fitness than physical inactivity. However, we also found that physical inactivity was independently associated with cardiorespiratory fitness in adolescents. Among adolescents who met the physical activity recommendations, those with lower levels of physical inactivity had significantly higher cardiorespiratory fitness than their peers with higher levels of physical inactivity. Based on these findings, we conclude that it is important to develop preventive strategies that encourage young people not only to engage in sufficient amounts of moderate-to-vigorous physical activity but also to reduce the time spent in various forms of sedentary behaviour. telesna nedejavnost sedeč življenjski slog telesna dejavnost telesna sestava indeks telesne mase odstotek telesnega maščevja obseg pasu srčno-dihalna zmogljivost slovenski mladostniki physical inactivity sedentary lifestyle physical activity body composition body mass index body fat percentage waist circumference cardiorespiratory fitness Slovenian adolescents true false false [N.
