    Analysis of the correlation between body composition, construction and aerobic capacity in teenage team sport training
    (Uniwersytet Rzeszowski, 2018) Matłosz, Piotr; Michałowska, Jadwiga; Sarnik, Grzegorz; Herbert, Jarosław; Przednowek, Krzysztof; Grzywacz, Renata; Polak, Ewa
    Introduction. Research results indicate that a low level of physical fitness is associated with a high percentage of fat in the body and low levels of physical activity. The aim of this work was to assess the relationships between selected morphological indicators, and the level of aerobic capacity in adolescents attending the schools with team sports. Material and methods. The studies covered students participating in sports in middle school and high school; the study group included 90 boys aged 13-19 years. Body height and weight were measured as well as waist and hip circumference. Body weight components were assessed by using a Tanita Body Composition Analyzer. A Fitnessgram® test battery was used to assess physical fitness. Results. Research results indicates systematic increase of somatic characteristics such as weight, body height and waist and hips circuits with age. Taking into account the results obtained with the PACER test indicate a very good aerobic capacity of tested boys. Conclusions. Age is a factor that improves motor fitness of physically active adolescents. There is no linear relationship between BMI and fitness among the boys who regularly train team sports, but both lower and higher BMI values seem to be connected with lower physical fitness.

    Decreased Bioelectrical Impedance Phase Angle in children and adolescents with newly diagnosed type 1 diabetes: A case-control study
    (2018) Więch, Paweł; Bazaliński, Dariusz; Binkowska-Bury, Monika; Korczowski, Bartosz; Mazur, Artur; Dąbrowski, Mariusz
    Objective. The aim of this study was to assess the body composition and nutritional status of children and adolescents with newly diagnosed type 1 diabetes by using bioelectrical impedance analysis (BIA) with phase angle (PA) calculation. PA is considered to be the most sensitive indicator of the nutritional and functional status and it has not been evaluated in such population yet. Research Design and Methods. 63 children and adolescents aged 4 to 18 years, with newly diagnosed type 1 diabetes, were included in the study. Control group consisted of 63 healthy children and adolescents, without diabetes or other chronic disease having impact on the nutritional status, strictly matched by gender and age in a 1:1 case-control manner. In both groups a BIA was performed and PA was calculated. Results. Diabetic patients had highly significantly lower PA, 4.85 ± 0.86 vs. 5.62 ± 0.81 respectively, P<0.001 compared to control subjects. Also lower percentage of body cell mass (BCM%), 46.89 ± 5.67% vs. 51.40 ± 4.19% respectively, P<0.001, lower body cell mass index (BCMI), 6.57 ± 1.80% vs. 7.37 ± 1.72% respectively, P=0.004 and lower percentage of muscle mass (MM%), 44.61 ± 6.58% vs. 49.40 ± 7.59% respectively, P<0.001, were found in diabetic group. Conclusions. The lower PA score together with lower MM%, BCM% and BCMI in diabetic patients indicate their worse nutritional and functional status compared to healthy subjects. To assess the predictive and prognostic value of these findings further prospective studies in this population are required.
