Acta Gymnica 2016, 46(4):155-161 | 10.5507/ag.2016.017

Background: The Movement Assessment Battery for Children - 2nd edition (MABC-2) is used for the assessment of motor proficiency and identification of motor impairments in 3-16 year old children. Although there are some gender differences in the motor development of children, in the MABC-2 test the same tasks and norms are used for both genders. Objective: The aim of the study was to determine gender differences in performance of motor tasks involved in the MABC-2 test in adolescents aged 15 to 16. Methods: Participants (N = 121, 50 boys and 71 girls, mean age 16.0 ± 0.5 years) randomly...

Acta Gymnica 2016, 46(4):162-173 | 10.5507/ag.2016.021

Background: Great importance has been given in recent years to the impact of focus of attention cues during skills execution but not during real game play, where more cognitive skills are involved besides technical performance. Objective: The purpose of the present study was to examine the effect of internal and external focus of attention instructions on the components of the game performance (decision making, skill execution, base) in tennis. Methods: The participants (N = 60) were divided into three groups and followed an intervention training program that lasted 6 weeks; IF group (n = 20) under internal focus of attention...

Acta Gymnica 2016, 46(4):174-183 | 10.5507/ag.2016.016

Background: Female triple jumping is a relatively new athletics event. A limited number of researchers have focused on comparing male and female jumpers competing in international events, resulting in scarce findings in the literature regarding gender differences of the determinants of triple jump performance. Objective: The aim of the study was to examine the possible gender differences in the approach step characteristics, the spatiotemporal parameters of the separate phases of the triple jump as performed by athletes participating in sub-elite international events. Methods: The male and female participants of the 2015 European Team Championships...

Physical fitness of primary school children in the reflection of different levels of gross motor coordination

Ingrid Ružbarská

Acta Gymnica 2016, 46(4):184-192 | 10.5507/ag.2016.018

Background: Lower level of motor competences may result in unsuccessful engaging of children in physical activities as early as pre-school age and also prepubescent ages. This may subsequently lead to a spiral of forming negative attitudes towards an active lifestyle and may be accompanied by a negative trend in weight status and physical fitness outcomes. Objective: The aim of the study was to identify and analyze differences in physical fitness and somatic parameters of primary school-aged children according to level of their gross motor coordination. Methods:  A sample of 436 children aged 7 to 10 years, of which were 222 girls...

Acta Gymnica 2016, 46(4):193-200 | 10.5507/ag.2016.020

Background: Children's and youth education is becoming more and more demanding. In conjunction with development of information technology, this fact negatively affects lifestyle of children and youth. Apart from families, schools should play a crucial role in healthy lifestyle promotion in children and youth. Objective: The present study aimed to assess differences in physical activity (PA) and physical inactivity (PI) among primary and secondary school boys and girls in specific segments of a school day. Methods: The research was conducted between 2010 and 2014 at 15 secondary schools (SS) and 9 primary schools (PS) in the Silesia-Katowice region...

Time-motion analysis and physiological responses of small-sided team handball games in youth male players: Influence of player number

Jan Bělka, Karel Hůlka, Michal Šafář, Lada Dušková, Radim Weisser, Václav Riedel

Acta Gymnica 2016, 46(4):201-206 | 10.5507/ag.2016.019

Background: Effective training depends on knowledge of a sport's requirements. Small-sided games (SSG) are a spontaneous form of specific training, where exercise intensity can be manipulated mainly by modifying external factors. In SSG the players develop technical and tactical skills in the similar situations, such as during a match and can also develop their physical skills. Objective: The purpose of this study was to examine the distance covered and physiological response of altering the number of youth male players during small-sided team handball games with modified rules. Methods: The subjects consisted of 12 male youth team handball players...
