Annelies Matthé, Donald N. Roberson Jr., Yael Netz

Acta Gymnica 2015, 45(4):159-165 | 10.5507/ag.2015.019

Background: The decline in cognition and physical fitness is common in advanced age. Objective: The relationship between cognition and aerobic capacity was compared to the relationship between cognition and balance. Methods: Twenty one females and six male residents of a Czech senior center participated in the study (mean age: 77.5 ± 7.0; range: 62-86 years). The Mini Mental State Examination (MMSE) was used for assessing cognition, the Berg Balance Scale (BBS) for assessing balance, and the 6-Minute Walk Test (6MWT) assessed physical fitness. Based on the MMSE scores, two groups of cognitive functioning were formed - high...

Jakub Svoboda, Adéla Dvořáčková, Miroslava Jirásková, Michaela Bolcková, Petra Majewská

Acta Gymnica 2015, 45(4):167-176 | 10.5507/ag.2015.020

Background: Dramaturgy is a specific method of course design and conduct used in experiential education in the Czech Republic. However, little is known about how the application of dramaturgy affects participants in experiential education. This paper explores dramaturgy in a winter expeditionary course organized by Vacation School Lipnice and participants' experience. Objective: Firstly, to explicate how the dramaturgy was used to design and conduct a winter expeditionary course by Vacation School Lipnice. Secondly, to explore the participants' experience. Methods: Content analysis was employed, using data from twelve unstructured interviews made with...

Comparison of body fat using various bioelectrical impedance analyzers in university students

Petr Kutáč, Miroslav Kopecký

Acta Gymnica 2015, 45(4):177-186 | 10.5507/ag.2015.021

Background: At present, the portfolio of devices using the bioelectrical impedance (BIA) method is continuously expanding as a result of the wide use of this method in the field as measurements by this method are fast and staff training is simple and reasonably priced. Nonetheless, the problem is that despite using the same method, bioimpedance analyzers can differ in many parameters. They use different electric current frequencies, a different number of electrodes and the electric current may be conducted through different parts of the body.Objective: The main objective of the study is to compare and evaluate the differences of values of the analysis...

System of gait analysis based on ground reaction force assessment

František Vaverka, Milan Elfmark, Zdeněk Svoboda, Miroslav Janura

Acta Gymnica 2015, 45(4):187-193 | 10.5507/ag.2015.022

Background: Biomechanical analysis of gait employs various methods used in kinematic and kinetic analysis, EMG, and others. One of the most frequently used methods is kinetic analysis based on the assessment of the ground reaction forces (GRF) recorded on two force plates. Objective: The aim of the study was to present a method of gait analysis based on the assessment of the GRF recorded during the stance phase of two steps. Methods: The GRF recorded with a force plate on one leg during stance phase has three components acting in directions: Fx - mediolateral, Fy - anteroposterior, and Fz - vertical. A custom-written MATLAB script was used for gait...

Active commuting of the inhabitants of Liberec city in low and high walkability areas

Lukáš Rubín, Josef Mitáš, Jan Dygrýn, Jiří Šmída, Lukáš Gábor, Adam Pátek

Acta Gymnica 2015, 45(4):195-202 | 10.5507/ag.2015.023

Background: Active commuting in terms of everyday transport to school or work can have a significant effect on physical activity. Active commuting can be influenced by the environment, and examples from abroad show that current environmental changes tend mostly to promote passive forms of commuting. A similar situation of decreasing active commuting might be expected in the Czech Republic. However, little information has been published to date about the issue of active commuting among the inhabitants of our country. Objective: The main objective of the present study is to describe the active commuting patterns of the inhabitants of Liberec city in...

Effect of lower limb preference on variability of centre of pressure movement during gait

Zdeněk Svoboda, Lucia Bizovská, Zuzana Kováčiková, Patrik Kutílek, Roman Cuberek, Miroslav Janura

Acta Gymnica 2015, 45(4):203-207 | 10.5507/ag.2015.024

Background: Centre of pressure (COP) movement variability, as an example of 'end-point' variability (stability), may be one of the indicators that can assess the functional gait asymmetry caused by foot preference in relation to fall risk. Objective: The aim of this study was to investigate the possible differences in COP movement variability during the stance phase of gait caused by both aging and lower limb preference. Methods: Two groups of females participated in this study: Younger (n = 25, age 22.2 ± 1.8 years) and Middle-aged (n = 25, age 56.6 ± 4.9 years). COP movement and ground reaction forces during gait at self-selected speed...
