“…Even short-term sport-specific training has shown to decrease the percentage of body fat in youth athletes [3]. Sedentary life-style, especially among urban school children, leads to retardation of growth and functional development of boys and girls, reduced adaptive capacity of young adolescents, and increased frequency and duration of diseases [4].…”

AbstractBackgroundThe purpose of this study was to investigate the morphological and isokinetic strength asymmetry and magnitude in young athletes.MethodsOne hundred and thirty nine male subjects (soccer, floorball, non-athletes) were measured for proportion of muscle mass between upper extremities (BADΔ) and lower extremities (BLDΔ). Moreover, the peak muscle torque of knee extensors (PTE) and flexors (PTF), ipsilateral (H:Q) and bilateral strength ratio (Q:Q, H:H) were measured.ResultsWe found significant differences in observed parameters with respect to different sport activities (F = 13.02, p = 0.00, $\eta^2_p$= 0.80). Higher values of BADΔ were observed in the non-active (0.19 ± 0.11 kg) group compared with soccer players (0.10 ± 0.11 kg). We found a lower value of BLDΔ in floorball players (0.32 ± 0.11 kg) compared with soccer players (0.58 ± 0.27 kg) and non-active boys (0.63 ± 0.28 kg). Results revealed significantly higher PTE in soccer players compared with non-active boys and floorball players and higher Q:Q ratio in soccer players (10.99 ± 7.75%) compared with non-active boys (7.47 ± 5.92%).ConclusionsThis study revealed that there are morphological and strength asymmetries in the observed groups, which may have potential maladaptive effects (e.g. uncompensated overload of extremity) in athletes affected by specific load.

“…On the other hand, insufficient physical activity can be related to a larger number of obese children, and this is what the research points out (Martinović & Pelemiš, 2015). That is why there is an intense need for monitoring and improving cardio-respiratory and motor status of children (Burdyukova et al, 2012. Daily participation in different forms of additional physical activities has a positive effect on the growth and development of a child's organism (Eathern et al, 2013;Prskalo, 2015), and the significance of physical activities is particularly stressed in pre-school age.…”

The research included the sample of 114 pre-school children aged 6 and 7, with average values of height (TV=123.23 cm ± 5.43) and weight (TT=24.53 kg ± 2.71). The children were divided into two groups: (E) experimental group (n=55), which had an additional programme of kinesiology activities lasting for 12 weeks, and (K) control group (n=59), which, apart from regular activities in physical education classes in the kindergarten did not have a programme of kinesiology activities. The aim of the research was to determine the latent structure of motor abilities before and after the application of kinesiology activities, and to determine the compatibility of factor saturation. Correlation was performed by Pearson correlation coefficient, and determination of the structure of motor activities was performed by factor analysis and by the method of principal components with bent promax rotation of isolated principal components. The Tucker index of saturation factor was used for determining the compatibility of isolated factors. Research results indicate that both in the initial and the final measurements of both tested groups, a two-dimensional structure of motor abilities was determined, consisting of coordination and strength, which could most appropriately be defined as one, general motor factor. The congruence between the isolated factors in E and K groups gained in the initial and final measurements shows that there are no differences in the structure of isolated factors. It can be concluded that motor functioning of children is still under the mechanism of structuring movement, so after the application of kinesiology activities the same factors remained, and quality changes in the structure of motor abilities have not been detected in the tested age.

“…After recognising the findings of current research, a lack would be seen in the insufficient number of findings which point at the facts about whether and to which extent the state of nourishment influences the motor abilities of children. Considering the fact that the general public is more and more concerned about obesity in children and insufficient physical activity, there is an intensive tendency to follow obesity and improve the motor status of children (Burdyukova, Pustovalov, Oranskaya, Pertsov, & Gurevich, 2012). This is why this study should give answers on questions whether the state of nourishment of children can determine their motor state.…”

The aim of the research is to determine whether there are gender differences between younger school-age children, and whether those differences within the sub-sample are influenced by the state of mass and motor skills. The whole sample included 285 respondents age 7.27±0.43, of which 144 boys (50.52%), and 141 girls (49.48%) who attended the first grade on the territory of the Province of Vojvodina (Republic of Serbia). The Eurofit battery of tests was used. The research results show that the prevalence of children with severe thinness in the whole sample is low 3.87%; children with normal mass 65.26%; pre-obese children only 18.59% and obese children only 12.28%, so that gender differences in motor skills considering the whole sample, apart from the mass, are between average values for boys considering explosive strength of the lower extremities, repetitive strength of the body and agility. Statistically significant differences within the sub-sample considering motor abilities were seen neither in boys nor in girls of different mass. The research findings show that there is significant percentage of children with normal mass and that the flow of their mass is within their growth and development. Their motor development within the sub-sample also flows equally, and gender differences are present because of differentiation of motor skills, which appears in this period. The authors think that greater differences and variables in respect to mass and motor activities are to be seen in the period of pre-puberty.
