Agility performance in athletes of different sport specializations

Erika Zemková, Dušan Hamar

Acta Gymnica 2014, 44(3):133-140 | 10.5507/ag.2014.013

Background: Data on agility skills in different populations using pre-planned, change of direction speed tests have previously been reported. However, there are no available data on the agility times of athletes specializing in different sports obtained from Reactive agility tests. Objective: The study compares agility time in groups of athletes of different sports where agility is one of the limiting factors of performance. Methods: Altogether 282 athletes of 14 sport specializations performed the Agility test. Their task was to touch, as fast as possible, with either the left or the right foot, one of four mats located outside...

Acta Gymnica 2014, 44(3):141-147 | 10.5507/ag.2014.014

Background: Differences between muscle strength and power of lower limbs is one of the factors associated with falls in the elderly population. Muscle strength asymmetry of lower limbs increases with age. Objective: The aim of the study is to assess differences in the volume and intensity of physical activity (PA) in the subgroups of women being at higher and lower risk of falls (with and without strength asymmetry of the knee extensors of dominant and non-dominant lower limb). Methods: Data from 42 women (age 56.3 ± 4.4 years; weight 76.5 ± 16.1 kg; body height 164.3 ± 5.2 cm;...

Acta Gymnica 2014, 44(3):149-153 | 10.5507/ag.2014.015

Background: Obesity and overweight are defined as abnormal or excessive fat accumulation and are associated with balance disorders. Objective: To assess the postural stability in a natural stance in overweight and obese women based on center of pressure (CoP) velocity in the anterior-posterior (AP) and medial-lateral (ML) directions. Methods: A total of 102 women categorized according to body mass index into normal weight, overweight and obese categories underwent a measurement of quiet standing with their eyes open (EO) and with their eyes closed (EC). Postural stability was assessed with a force platform. The mean CoP velocity was evaluated in both...

Autonomic cardiac regulation and morpho-physiological responses to eight week training preparation in junior soccer players

Michal Botek, Jakub Krejčí, Radim Weisser

Acta Gymnica 2014, 44(3):155-163 | 10.5507/ag.2014.016

Background: Training preparation in soccer is thought to improve body composition and performance level, especially the maximal aerobic capacity (VO2max). However, an enhancement in performance may be attenuated by the increase of fatigue. Heart rate variability (HRV) as a non-invasive index of autonomic nervous system (ANS) activity has been considered to be a sensitive tool in fatigue assessment. Objective: This study was focused to evaluate the response of ANS activity and morpho-physiological parameters to eight week training preparation. Methods: Study included 12 trained soccer players aged 17.2 ± 1.2 years. Athletes...

The analysis of a battery of motor tests as a predictor of future athletic performance in children of athletic school sport classes

Vítězslav Prukner, Dagmar Sigmundová

Acta Gymnica 2014, 44(3):165-173 | 10.5507/ag.2014.017

Background: The prediction of future sport performance belongs among the most difficult tasks when choosing new talents. A great amount of attention is paid to designing a suitable battery of tests applicable to sport talent selections. Objective: The aim of this study is to analyse a battery of motor tests to assess the development of sports talents in athletic sport classes in order to suggest a battery of tests which will be able to produce an accurate assessment. Methods: The research was carried out among athletic classes in the years 2000-2007. As part of the study, 197 sixth grade students were monitored longitudinally...

Job dissatisfaction among certified adapted physical education specialists in the USA

Acta Gymnica 2014, 44(3):175-180 | 10.5507/ag.2014.018

Background: Professionals working in the area of special education are exposed to the unique situation of occupational stress. Adapted physical education teachers are experiencing several symptoms of the burnout phenomenon. Objective: The purpose of this study was to identify factors causing job dissatisfaction among certified adapted physical education specialists in the USA. Methods: The survey was developed based (a) on Herzberg's (1959) theory of job satisfaction, and (b) a pilot study, which examined specific factors of job dissatisfaction among adapted physical education (APE) teachers in the USA. The survey consisted of...
