BackgroundThe dramatic increase in the prevalence of obesity in developed and developing countries has become a major health care concern. Accordingly, there is growing recognition of the relationship between health-related quality of life (HRQOL) and obesity in the pediatric population. This study aimed to explore the relationship between HRQOL and different indicators of obesity in children aged 7–8 years.MethodIn total, 182 children participated in this study (mean age 7.71 (0.29) years, 48.91% girls). To assess obesity, an InBody 230 analyzer was used to calculate body mass index (BMI) and body fat percentage (BFP). The proxy version of the KIDSCREEN-27 questionnaire was used to assess HRQOL.ResultsAmong boys, 17.2% were overweight and 4.3% were obese according to BMI, while in terms of body fat percentage (BFP), the corresponding percentages were 12.9 and 9.7%, respectively. Among girls, the prevalence of overweight and obesity was 11.2 and 9.0% by BMI and 10.1 and 7.9% in terms of BFP, respectively. The analysis of BFP showed a significantly higher score in normal weight boys than in obese boys in the Social Support & Peers domains (KW H-test = 10.472, p = 0.03), while in girls, there were no significant differences between weight categories and any HRQOL dimensions.ConclusionObesity at 7–8 years of age could negatively affect some HRQOL domains; in particular, obese boys may have low social support and peer functioning.

The general concept of dynamic neuromuscular stabilization (DNS) is, among other things, directly aimed at core stabilization as well as proper and “stable breathing”. DNS is based on the integration of the stabilization system which is mainly composed of intersegmental spinal muscles, deep neck flexor muscles, the diaphragm, abdominal muscles, and the pelvis. Although it is a relatively recent rehabilitation and training concept, a lot of researchers focus on DNS due to its positive effects. The review started with the hypothesis that the DNS concept achieves high and positive results on the locomotor system in terms of better core stabilization, increasing the functionality of the locomotor system and quickening the rehabilitation process. The method included searching Google Scholar, PubMed and Web of Science for scientific material. Out of 50 reviewed scientific papers, the sample was consisted of 12 papers that are, according to their research topic, compatible with the review in question. The results of the review indicate that the DNS concept has positive effects on the functionality of the locomotor system.

Cilj ovoga rada je analiza nivoa snage pojednih mišićnih grupa, odnosno utvrđivanje razlika u varijablama : repititivna snaga trupa, eksplozivna snag a nogu i statička snaga ruku i ramenog pojasa kod dece narušene posture. Istraživanjem je bilo obuhvaćeno ukupno 67 ispitanika sa područja opštine Subotica, od čega je merenjima bilo podvrgnuto 22 ispitanika sa kifotičnim narušenim držanjem tela, 18 ispitanika sa lordotičnim lošim držanjem tela , dok je ispitanika sa ravnim stopalima bilo 27. Za merenje odnosno procenu nivoa snage pojedinih mišićnih grupa je primenjena baterija standardizovanih testova: izdržaj u zgibu, skok u dalj iz mesta i podizanje trupa za 60 sekundi. Rezultati do kojih se došlo ukazuju da postoje statistički značajne razlike u manifestaciji snage u sve tri varijable: kifotično loše držanje tela, lordotično loše držanje tela i ravna stopala.

The sedentary form of behaviour, the effective holding of the body are potential causes of the formation of muscular asymmetries, and thus of poor body posture. The aim of the paper is to determine the differences in posture of children of different levels of physical activity. The research involved an assessment of a sample of 42 handball players 13.02 ± 0.89 years and 32 non-athletes 13.16 ± 0.88 years. Three tests were used to evaluate the presence of poor posture, to evaluate the scoliotic poor posture - Adam’s forward bend test, to estimate the kyphotic poor posture –Reclination test with the contraction of the extensor muscle to assess the lordotic poor posture – Contraction test of the abdominal muscles. The obtained results of the chi square of the test indicate that there are no statistically significant differences between the analysed groups of subjects regarding the presence of the scoliotic (p = 0.85), the kyphotic (p = 0.77) and the lordotic poor posture (p = 0.82) between the defined groups. The assumption is that boys are involved in sports activities due to the impaired posture in adolescent age, in order to prevent further progression and formation of new bodily deformities and to avoid similar conditions.

The assessment of the locomotor system functionality is of great importance for both athletes and those not doing any kind of sport. It is assumed that a structured physical activity has a number of positive effects to the locomotor system. The study included 31 samples that are active athletes and 25 samples not involved in any kind of training process. The aim of the study was to evaluate the effect of the training process on the functional stability and mobility of the locomotor system. The results indicate that there is a significant statistical difference in four analyzed variables: hurdle step (χ2=7,52; p=0,02), active straight leg raise (χ2=9,65; p=0,01), trunk stability push up (χ2=9,81; p=0,01) and rotatory trunk stability (χ2=11,63; p=0,00) in favor of the athlete group.
