The Effects of neck cooling during intermitent exercise
 Čuda, Radek ; Hojka, Vladimír (advisor) ; Baláš, Jiří (referee)
Title: The Effects of neck cooling during intermitent exercise Objectives: The aim of the study was to determine effects of neck-cooling during intermitent exercise on heart rate and heart rate recovery changes, intermitent sprint performance and rating of perceived exertion. Methods: The crossover study design and MBD analysis was used. 19 healthy subjects absolved test consisted of: 4 x 2 min. repeated shuttle run test (HIMS), 1 minute recovery interval for cold pack application on the neck, repeated sprints 10 x 20 m and 2 minute recovery interval for cold pack application on the neck. Results: Neck cooling during intermitent exercise can lower heart rate and improve faster heart rate recovery. Impact on intermitent sprint performance is unclear because of missed data. The rating of perceived exertion is on the same level after neck-cooling. Keywords: neck-cooling, intermitent exercise, HIMS, HRR, MBD

Running locomotion in common and water environment
 Čuda, Radek ; Vindušková, Jitka (advisor) ; Jurák, Daniel (referee)
RUNNING LOCOMOTION IN COMMON AND WATER ENVIRONMENT Objectives: To offer a comprehensive view how to use various types of water running for training purposes. Summarize the significant differences between the water and classic running with orientation on physiology and biomechanics. Methods: Review of current knowledge from the literature. Comparative analysis of deep water running and classic running with slow and high frequency from video recordings. The aim of analysis were changes in the angles of the hip (flexion and extension), knee (flexion) and the elbow (flexion) joint, forward bending of the trunk and stride length. Results: During low stride frequency running is in the water greater knee (+ 41.2 ř) and hip (+ 26.7 ř) flexion, trunk more bent (+ 6.8 ř) and stride is shorter (by 1.61). During high stride frequency running is in the water greater knee flexion (+ 32.9 ř), greater trunk forward bending (+ 9.3 ř) and shorter stride (by 1.71). At low frequency were changes between conditions in all subjects more similar than at high frequency. When comparing the water running at low and high frequency the forward bending of the trunk was greater at high frequency (+ 9.6 ř) Other results were not conclusive. Keywords: water running, physiology ,biomechanics
