Kadlec, Jan ; Zahálka, František (advisor) ; Strnad, Pavel (referee)
Title: Selected parameters of postural stability in elite sport dance group. Objectives: The aim of this study is to evaluate selected parameters of postural stability in elite sport dancers in Czech Republic during their preparatory period and to define the relation of postural stability to body composition, equality and ability of explosive strength production of lower limbs. Methods: The group of 10 elite sport dancers, composed of men (n=5, age=25,1±2,4 years, height=181,9±3,8 cm, weight=73,7±7,5 kg) and women (n=5, age=24±3,2 years, height=169,1±5,7 cm, weight=53,8±3,6 kg), was longitudinally observed during their preparatory period. At the beginning and on the top (national championship) postural stability, body composition and dynamic performance were evaluated. These following devices were used for testing: force plate FootScan (RScan International, Belgium), bioimpedance analyzer BIA 2000M (Datainput, Germany) and Tanita (Tanita Corporation, Japan), dynamometric force plates Kistler 8611 (Kistler, Switzerland). Results were evaluated by descriptive and inductive (paired t-test) statistics. Results: Results showed high similarity of followed selected parameters in elite sport dancers at the beginning and also at the top of preparatory period. Postural stability was slightly impaired, but...

Křivohlávek, Jakub ; Bunc, Václav (advisor) ; Strejcová, Barbora (referee)
Title: Effects of dance sport in the musculoskeletal system of the individual Objectives: The goal is to musculoskeletal examination of selected individuals and evaluation the effect of dance sport on examined status. The results should be the basis for further research in this area. Methods: Kinesiology analysis, bioimpedance analysis and X-ray were used for scrutiny of the musculoskeletal system. Primary and secondary data were analyzed afterwards. Results: Findings of struktural deformities: flat feet (both), both sided hallux valgus with incipient degenerative changes of I. MTP joint (male), limit angle of I. MTP joint of left leg (female). These deviations are related to the using of dance shoes. Muscle imbalance upper thoracic region and lateral imbalance of tested people are the result of the prescribed holding and leading used in dance. Keywords: dance sport, musculoskeletal system, muscle imbalances, feet deformities

The Influence of the Dance Sport on Poise
Vitošek, Pavel ; Fričová, Marie (advisor) ; Panská, Šárka (referee)
Title: The Influence of the Dance Sport on Poise Objectives: The main goal of this diploma work is the creation of coordination maps of selected muscular structures in the body, its evaluation and assessment of the impact of the dance sport on poise. The research deals with the kinesiological analysis of muscle activation affecting postural stabilization of the dance couple. Methods: Method of the surface electromyography combinated with kinematography analysis used synchronized video recording has intended level of postural muscle activity in dance. Results: Interpretation of the coordination maps selected muscular structures was founded that dance sport may result in muscle imbalances in the torso. Keywords: Dance sport, Poise, Surface electromyography, Posture, Muscle disbalance
