A relationship between lateral symmetry of the shoulder joints during modified handstand execution and the Upper Quaretr Y Balance Test
Havelka, Ondřej ; Malíř, Roman (advisor) ; Chrudimský, Jan (referee)
Title: Relationship between lateral symmetry of the shoulder girdle in modified handstand position and Upper Quarter Y Balance Test Objectives: The aim of this study is to test the relationship between the lateral symmetry of the shoulder girdle in the modified handstand position and the score in the Upper Quarter Y Balance Test. Methods: This empirical research investigated the connection between the lateral symmetry of the shoulder girdle in a modified handstand position and the Upper Quarter Y Balance Test (UQYBT) score. Shoulder stability was assessed using the UQYBT score and categorized as shoulder with higher score (P, L, S). The quality of the handstand was evaluated by examining marker displacement relative to the baseline on the y-axis, resulting in higher marker position (P, L, S) and x-axis relative to the line segment, resulting in farther marker position (P, L, S). The relationship between these variables was analyzed using the Goodman- Kruskal λ association test, which measures the strength of association between two categorical variables (UQYBT and higher shoulder (P/L/S), and UQYBT and farther shoulder (P/L/S). The λ coefficient, ranging from 0 to 1, was used to interpret the relationship. Results: The results showed a minimal and statistically insignificant relationship between...

Influencing postural stability in the standing position on the hands
Fiala, Tomáš ; Krištofič, Jaroslav (advisor) ; Chrudimský, Jan (referee)
Name: Influencing postural stability in the handstand posture Characteristic: Theoretical part of thesis explains essential terms regarding a postural stability, motor skills, particularly coordination, respectively balance skills. Thesis deals with the issue of maintaining the postural balance in handstand position. Objectives: The main goal of thesis is finding, if and in what amount can applied movement program improve parameters of postural stability, within the research group. Methods: The research included 7 students took the entire cycle (2 men, 5 women; age of 22,8 ± 1,64 year, body weight 61,5 ± 7,45 kg, body height 169,5 ± 7,51 cm. For the measurement of postural stability device was used FOOTSCAN, sensing frequency has been selected 33 Hz. Test battery was composed of four postural stability tests and the handstand stability test. For evaluation of the working parameters have been taken to the COP in the antero-posterior direction (Δx), in the right-left direction (Δy) and total distance COP (TTW). Results: Results has shown a slight improvement of postural stability in handstand, after completion of the movement program. There was a lack of a control group, therefore no statistic significance was concluded. Furthermore, no significant change in postural stability was detected after...
