 Abstract
Regular physical activity is playing a pivotal role in developing cardiorespiratory fitness (CRF), which has numerous benefits for present and future health. The aim of this study was to explore CRF in adolescents, in regards to their sports participation, body mass index (BMI), age, and gender. The sample consisted of 172 students involved in sport (79 female) aged 12-14 (Mean 13.1, SD 0.5). The 20-m shuttle run test was used to estimate CRF. Data regarding years being active in sport, number of trainings weekly, age, and gender were acquired by a questionnaire, and BMI was calculated by using standard formula after measuring participants’ weight and height. To investigate the relationship between potential predictors and CRF, we performed multiple regression analysis. The results revealed that overall model predicted CRF significantly, R = .58, R2 = .34, F(5, 166) = 16.74, p < .01. Further, BMI and female gender were negatively associated with CRF, β = - .33, p < .01 and β = - .40, p < .01, respectively. The only positive predictor of CRF was number of trainings weekly, β = .22, p < .01. These findings could emphasize the importance of frequent physical activity in a highly structured environments (e.g., sport clubs) for developing CRF. Further research could focus on the relationship between sports training variables and CRF in different sports.
