Acta Gymnica 2017, 47(3):105-111 | 10.5507/ag.2017.013

Background: Balance is a fundamental part of many movement tasks a child performs. Maintaining upright posture is a complex process involving multiple body parts and functional systems. Objective: This study aimed to explore the mean amplitude and velocity of the center of pressure (COP) displacements during static balance tests in children with and without disabilities. Methods: Participants were 34 children (age 8.5 to 10.8 years) including 6 typically developed children, 8 children with hearing, 8 children with visual and 12 children with intellectual disabilities. Static balance data were obtained in 15 s bipedal stance with eyes open and...

Vagal activity and oxygen saturation response to hypoxia: Effects of aerobic fitness and rating of hypoxia tolerance

Tomáš Macoun, Michal Botek, Jakub Krejčí, Andrew J. McKune

Acta Gymnica 2017, 47(3):112-121 | 10.5507/ag.2017.014

Background: A reduction in the inspired oxygen fraction (FiO2) induces a decline in arterial oxygen saturation (SpO2) and changes of heart rate variability (HRV). It has been shown that SpO2 and HRV responses to similar levels of acute normobaric hypoxia are inter-individual variable. Variable response may be influenced by normoxia reached maximal oxygen uptake (VO2max) value. Objective: The primary aim was to assess HRV and the SpO2 response to hypoxia, and examine the association with normoxic VO2max. Methods: Supine HRV and SpO2 were monitored during normobaric hypoxia...

Acta Gymnica 2017, 47(3):122-129 | 10.5507/ag.2017.015

Background: Puberty is a central process in the complex set of changes that constitutes the transition from childhood to adolescence. This period of maturation is characterized by a growth spurt which affects virtually the whole skeleton and muscles and thus affecting children's motor performance. Objective: The present study investigated the role of pubertal status in predicting success in rhythmic gymnasts' (RGs) performance. Methods: One hundred and twenty-six national- and international-level RGs (age: 11.95 ± 3.09 years, body height: 147.76 ± 14.61 cm, body mass: 37.75 ± 11.72 kg,...

Acta Gymnica 2017, 47(3):130-137 | 10.5507/ag.2017.016

Background: The development of new technologies has led to further improvements in prosthetic knee joints. Objective: The aim of this study was to compare angle parameters in knee and hip joints during the gait of transfemoral amputees and to determine the effect of the type of knee joint used on their symmetry. The study also compared pelvic movements in transfemoral amputees using different types of knee joints. Method: Eleven patients (5 female, 6 male, mean age 39.2 ± 10.1 years, height 171.8 ± 9.5 cm, mass 71.5 ± 11.0 kg) with a transfemoral amputation (5 used bionic knee,...

Mental health and quality of life benefits of a pedometer-based walking intervention delivered in a primary care setting

Tomas Vetrovsky, Jozef Cupka, Martin Dudek, Blanka Kuthanova, Klaudia Vetrovska, Vaclav Capek, Vaclav Bunc

Acta Gymnica 2017, 47(3):138-143 | 10.5507/ag.2017.017

Background: Physical activity level is positively associated with mental health and health-related quality of life. Primary care providers are ideally situated to offer physical activity interventions, and pedometers are commonly used as motivational tools to increase walking. However, several recent trials of pedometer-based interventions in primary care settings neither improved patients' quality of life nor reduced anxiety or depression, but these interventions only had relatively modest effects on physical activity levels. Objective: Our aim was to assess whether a pedometer-based walking intervention delivered in a primary care setting affects...

Effect of in-season neuromuscular and proprioceptive training on postural stability in male youth basketball players

Lukáš Ondra, Petr Nátěsta, Lucia Bizovská, Eliška Kuboňová, Zdeněk Svoboda

Acta Gymnica 2017, 47(3):144-149 | 10.5507/ag.2017.019

Background: Poor balance ability is a predictor of injuries of the lower extremity. Multi-intervention proprioception preventive programs, comprising balance training, strength, plyometric, agility, running, and stretching exercises, are effective in improving balance ability and reducing the risk of lower extremity injuries in athletes.Objective: The aim of the study was to examine the effect of a 20-week in-season multi-intervention proprioceptive neuromuscular training program on postural stability in male youth basketball players.Methods: Twenty-one elite male youth basketball players were divided into an intervention group (n = 10,...
