Physical activity and situational interest in mobile technology integrated physical education: A preliminary study

Xihe Zhu, Loren A. Dragon

Acta Gymnica 2016, 46(2):59-67 | 10.5507/ag.2016.010

Background: Mobile technology permeates every aspect of student lives. The question is whether mobile technology integration can produce desirable effects in the gymnasium. Objective: This preliminary study aimed to investigate the effects of mobile technology integration on student situational interest and physical activity fluctuation in physical education lessons.Methods: Sixth grade students (N = 53) were randomly placed into either an experiment group by class that utilized mobile technology-integrated resources (iPad and applications), or a comparison group that did not utilize technology. Both groups received five identical physical...

Differences in pre-planned agility and reactive agility performance in sport games

Jaromír Šimonek, Pavol Horička, Ján Hianik

Acta Gymnica 2016, 46(2):68-73 | 10.5507/ag.2016.006

Background: Authors in their contribution point to the differences in the methods of measurement of agility in the practice. Based on the experience of coaches as well as on their own experience have come to the conclusion that the Illinois Agility Test, which has long been used for the testing of agility in fact does not measure perception abilities and decision-making processes, since motor activity performed during the testing procedure represents a closed skill, where the only task of the tested person is to accelerate, decelerate and change the direction of running, while the task is known in advance. On the contrary, some authors recommend the...

Functional clinical typology of the foot and kinematic gait parameters

Jitka Marenčáková, Zdeněk Svoboda, Ivan Vařeka, František Zahálka

Acta Gymnica 2016, 46(2):74-81 | 10.5507/ag.2016.004

Background: The foot plays a key role in a standing posture, walking and running performance. Changes in its structure or function may alter upper segments of kinematic chain which can lead to formation of musculoskeletal disorders. Although functional clinical typology provides a complex view of foot kinesiology there is a lack of knowledge and evidence about influences of different foot types on human gait. Objective: The aim of the study was to analyse differences of kinematic gait parameters of lower extremity joints and pelvis between functional clinical foot types in healthy young men. Methods: Three-dimensional kinematic analysis by the Vicon...

Differences in kinematics of the support limb depends on specific movement tasks of take-off

Vladimír Hojka, Radka Bačáková, Petr Kubový

Acta Gymnica 2016, 46(2):82-89 | 10.5507/ag.2016.005

Background: Many sport activities are a sequence of jumps (running, jumping, hurdling etc.). Each jump flight phase is the result of the execution of the previous support phase. Objective: The goal of the research was to identify differences in adjustment of the support lower limb and differences in take-off kinematics in specific take-off movement task. Methods: 14 male athletes (22.6 ± 4.4 years; 182.4 ± 5.3 cm; 74.7 ± 6.2 kg) took part in a laboratory experiment. Each athlete performed five different take-off movements (running, acceleration running - second step,...

Positional differences in the cardiorespiratory, autonomic, and somatic profiles of professional soccer players

Martin Semjon, Michal Botek, Zbyněk Svozil, Andrew J. McKune

Acta Gymnica 2016, 46(2):90-96 | 10.5507/ag.2016.008

Background: In order to optimize training in soccer, knowledge about the specific position fitness demands and characteristics is required. Objective: The aim of the study was to determine whether there are position specific differences in somatic, cardiorespiratory and autonomic cardiac profiles of professional senior Czech soccer players. Methods: All players (N = 120) were divided into six groups according to field positions: goalkeeper (GK; n = 11), external defenders (ED; n = 15), central defenders (CD; n = 18), external midfielders (EM; n = 18), central midfielders (CM; n = 24) and forwards (F; n = 34). Players underwent...

The struggle for individuality: Investigating a long-term pursuit of a lifestyle sport activity

Jana Hoffmannová, Luděk Šebek, Pete Allison, Michael Maina, James Toogood

Acta Gymnica 2016, 46(2):97-104 | 10.5507/ag.2016.007

Background: Mainstream forms of media frequently portray "wild" or "epic" images of lifestyle sport activities showing the participants as "modern-day gladiators". This research set out to explore how closely aligned these stereotypes are with individual experiences. Objective: The purpose of this study was to identify and analyze factors which may contribute to a selected lifestyle sport activity becoming firmly rooted in an individual's life course. Methods: Data were collected through focus groups, individual interviews, lifeline method, and participant observation within focus groups. The sample included performance freeskiers, freestyle snowboard...
