(Wydawnictwo Uniwersytetu Rzeszowskiego, 2018) Herbert, Jarosław; Matłosz, Piotr; Grzywacz, Renata; Jaskierska, Patrycja; Sołek, Aleksander
Introduction. Organized physical activity (PA) is among factors that significantly influence the amount of realized PA. Aim. The aim of this study was to collect and analyze of the influence of BMI on the number of steps among women while undergoing obligatory sport camp as part of physical education studies and during study time at university. Materials and methods. The studies included women (n=60) ranging from 19 to 25 years of age. Their weekly physical activity was monitored using an accelerometer ActiGraph. The significance of the differences between the results for two consecutive measurements are pointed out among the same people, but under different conditions there was assessed at-student test for the variables. Compliance of measurement was described using testing and Bland-Altman chart. For the level of statistical significance p < 0.05 was adopted. Results. The requirements of the WHO on the minimum physical activity were met by almost all students. There is a lack of presence of a statistically significant relationship between BMI and the number of student steps, both in the case of measurement during study time (R = -0.03; p = 0.815) and at camp (R =-0.02; p = 0.865). Conclusions. Women are characterized by high activity (number of steps). BMI does not affect the number of steps for studies. Students meet the requirements of WHO (10000 steps).

Comparison of selected parameters of physical activity at school and at home in children aged 12 in rural areas in poland
(Polish Journal of Sport Tourism, 2018) Herbert, Jarosław; Warchoł, Krzysztof; Przednowek, Krzysztof; Grzywacz, Renata
Introduction. In recent years, research studies have demonstrated a significant decrease in physical activity (PA) amongst young people. Most of the young generation participate in sport and recreation too rarely, and they devote too much time to passive leisure. Diagnoses of physical activity at different stages of our lives, with particular emphasis on children and adolescents, are increasingly indicating that along with age, the level of physical activity, especially during leisure time, is decreasing. Material and methods. The aim of the study is to compare selected parameters of physical activity on a single day among students aged 12 and to determine how these parameters differ at school and at home. The study was conducted using an ActiGraph WGT3X accelerometer on a group of 100 students (50 girls and 50 boys) in a rural area of southern Poland. Results. The analysis showed that for parameters such as vigorous activity, total moderate-to-vigorous physical activity (MVPA), and step count, the observed difference between the time spent at school and outside of school was statistically significant (p < 0.05). All of these parameters were characterised by a higher level during school time. On the basis of the analyses performed, it was concluded that the school environment contributes to increasing youth’s physical activity. Effective educational programmes promoting physical activity in different forms should be addressed to youth as well as to parents (custodians), who are responsible for the physical development of their children.
Obesity and Body Composition in Preschool Children with Different Levels of Actigraphy-Derived Physical Activity—A Cross-Sectional Study
(Journal of Clinical Medicine, 2020-04-23) Wyszyńska, Justyna; Matłosz, Piotr; Szybisty, Agnieszka; Lenik, Paweł; Dereń, Katarzyna; Mazur, Artur; Herbert, Jarosław
Detailed associations between physical activity (PA) and body composition in preschoolers remain unclear. The aim of this study was to assess body composition among preschool children differentiated according to their levels of PA and to assess whether meeting the current PA recommendations is associated with a lower risk of obesity, determined by body mass index (BMI) and body fat percentage (BFP). Free-living PA was measured using accelerometers for 7 days in children aged 5 to 6 years. Bioelectrical impedance analysis was used to estimate body composition. Significant differences in content of BFP, fat-free mass (FFM), and total body water (TBW) were found between boys meeting and not meeting moderate-to-vigorous PA (MVPA) recommendations. Meeting the MVPA recommendation was associated with a twofold lower risk of obesity determined by BFP in boys but not in girls. In contrast, the total number of recommended steps per day was not related to adiposity in boys or girls. No statistically significant differences were observed in body composition indices and quintiles of MVPA. Boys in the 3rd–5th quintiles of steps per day presented significantly lower BFP and higher muscle mass and TBW than their peers in quintile 1. However, different associations were observed between body composition indices and quintiles of PA.
School Environment versus Home Environment – Comparison of Selected Parameters of Children Physical Activity
(Central European Journal of Sport Sciences and Medicine, 2018-09-02) Herbert, Jarosław
In recent years research have shown a significant decrease in physical activity (PA) among young population. Increasingly carried out diagnosis of physical activity at different stages of our lives, with particular regard to children and adolescents indicates that with age, level of physical activity, especially in leisure time is reduced. The purpose of the research is to compare the selected parameters of physical activity during one day among students aged 6–8 years old. The study was conducted with use of the accelerometer ActiGraph WGT3X on group of 54 children (30 – school and 24 – kindergarten). Analysis shows that for such parameters as MET’s, Vigorous, Total MVPA and Steps Counts one observed difference between the stay at school and sometimes school has statistical significance (p < 0.05). On the basis of the studies carried out it is shown that the school environment helps to increase physical activity among children in school and the fact is that these children are more active.
