Return to play after health complications associated with infectious mononucleosis guided on autonomic nervous system activity in elite athlete: A case study

Michal Botek, Pavel Stejskal, Jaroslav Větvička

Acta Univ. Palacki. Olomuc., Gymn. 2012 42(2): 7-14 | 10.5507/ag.2012.007

Background: Infectious mononucleosis (IM) is an acute serious illness which requires among other things an interruption of training. The return to play for athletes after IM is complicated and a long-term process which could result in the relapse of health complications linked fundamentally with the illness. Objective: The aim of this study was to design a convalescence program which leads to an improvement in physical fitness and provides a safe return to play without relapse of health complications for an elite athlete who suffered from IM. Methods: The convalescence program lasted almost 3 months. Training load was optimized...

Motor abilities, movement skills and their relationship before and after eight weeks of martial arts training in people with intellectual disability

Samo Masleša, Mateja Videmšek, Damir Karpljuk

Acta Univ. Palacki. Olomuc., Gymn. 2012 42(2): 15-26 | 10.5507/ag.2012.008

Background: A part of the population of people with intellectual disability is historically inclined to obesity and in a poorer health condition. That is the reason why sport should play an important role in their lives. Designing scientifically and professionally valid training programmes, consisting of the necessary methodology and didactical instructions for sport engagement of people with intellectual disability, is not only a challenge but has become a necessity for the near future. Objective: The aim of the study was to establish a correlation between selected motor abilities and motor skills of martial arts as well as how and...

Comparative analysis of the support phase during first two steps after leaving the starting blocks

Vladimír Hojka, Petr Kubový, Radka Bačáková

Acta Univ. Palacki. Olomuc., Gymn. 2012 42(2): 27-32 | 10.5507/ag.2012.009

Background: Biomechanical analysis of accelerated running dynamics provide valuable information about movement execution. The key phase of the movement is the ground contact phase, in which force impulses applied on the human body are generated. Objective: The main goal of the study was to analyze differences in the support phase during first and second ground contact off the blocks. Methods: 10 male athletes (22.9 ± 4.6 years) took part in laboratory experiment. Force-plate Kistler 9281 EA (Winterthur, Switzerland) was used to determine the contact forces in both steps independently. Matlab Software (The MathWorks, Inc.,...

A new view on the quality of Jacík's test

Roman Cuberek, Aleš Jakubec, Karel Hůlka, Michal Botek

Acta Univ. Palacki. Olomuc., Gymn. 2012 42(2): 33-40 | 10.5507/ag.2012.010

Background: A self-assessment of physical fitness requires a search for motor tests which do not make high material, spatial and skill demands necessary for tests' realization. In this manner, Jacík's test (JT) appears to be an appropriate one. Nevertheless, existing information about the test quality is not complete. Based on the motion content of this test, the test performance can be considered to be determined by the level of aerobic fitness. Objective: The aim of this study is to assess the reliability of JT and to determine degree of influence of aerobic fitness on JT performance. Methods: Eighty four PE university students...

Personality characteristics of Serbian male wheelchair and professional basketball players

Kasum Goran, Ljubiša Lazarević, Saša Jakovljević, Ljubica Bačanac, Fadilj Eminović

Acta Univ. Palacki. Olomuc., Gymn. 2012 42(2): 41-47 | 10.5507/ag.2012.011

Background: Sport, as social phenomena, may achieve a very positive influence on health and the social state of people with disability who practice it. In sport activities of athletes with disability, team sports may take a very important place. Objective: The aims of this study were: a) to investigate personality characteristics of male professional basketball players and wheelchair basketball players, b) to compare these characteristics of two kinds of athletes. Methods: For the purposes of this study, professional basketball players (N = 29) and wheelchair basketball players (N = 25) had completed a Cattell 16PF questionnaire...

The effect of biomechanical variables on the assessment of vaulting in top-level artistic female gymnasts in world cup competitions

Roman Farana, František Vaverka

Acta Univ. Palacki. Olomuc., Gymn. 2012 42(2): 49-57 | 10.5507/ag.2012.012

Background: A vaulting performance takes a short time and it is influenced by and affects the quantity of mechanical variables. After the 2000 Olympic Games, the traditional horse was replaced by a new vaulting table. While the biomechanical data of vaulting using the new table (post 2000 Olympic competition) are not available yet, there is a question what the current technique of handspring performed by top-level female gymnasts looks like. Objective: The aim of the study is to determine the biomechanical factors that govern success in the performance of the handspring and front somersault vaults. Methods: Eight top-level female...
