Effectivity of localized and whole-body active recovery strategies after exhaustive isometric finger flexor performance
Sechterová, Hana ; Baláš, Jiří (advisor) ; Vomáčková, Helena (referee)
Author: Title: Objectives: Methods: Results: Bc. Hana Sechterová Effectivity of localized and whole-body active recovery strategies after exhaustive isometric finger flexor performance Determine the effect of localized and whole-body active recovery on repeated exhaustive isometric performance of fingers flexors. Determine the effect of systemic and muscle oxygen kinetics on level of recovery of fingers flexors during two types of active recovery. 7 men (age 31,3 ± 8,3) and 6 women (age 30,7 ± 8,1) underwent tests of systemic and muscle oxygen kinetics, then repeated intermitent isometric contractions of fingers flexors until exhaustion in three visits. The randomly chosen type of active recovery (with global enagaging of muscles, with isolated engaging of fingers flexors) was applied among tests until exhaustion. The performance of fingers flexors until exhaustion was measured in the intermitent test (8 s contraction, 2 s relaxation). Systemic oxygen kinetics (VO2max) was measured by using maximal oxygen consumption and ventilatory anaerobic threshold (VT2). Muscle oxygen kinetics was measured by using infrared spectroscopy. The relationship among systemic and muscle oxygen kinetics and decrease of fingers flexors performance until exhaustion was calculated using the Pearson correlation...

Effect of local and complex recovery strategies on repeated isometric finger flexor performance
Krajčoviechová, Lucia ; Baláš, Jiří (advisor) ; Krupková, Dominika (referee)
Title: Effect of local and complex active recovery on repeated isometric fingers flexors performance Objectives: Comparation of the effect of three different types of active recovery on isometric performance of fingers flexors. Methods: The study was participated by 6 men (age 32,5± 8,9) and 2 women (age 30 and 42), who underwent three randomly chosen types of active recovery (with isolated engaging of upper extremities - HK, with isolated engaging of lower extremities - DK, with engaging of upper extremities lower extremities - HDK) during three visits with at least 48 hour gap. Their performance was measured with the help of alternate exercise (8 sec exercise/2 sec break). Exercise was repeated three times and during the break between exercises was applied one regeneration method. Results: The study shows that active recovery type DK is the most advantageous in comparison with active recovery type HK and HDK when talking about repeated performance of fingers until exhaustion. Time of the second performance decreased by ↓4,5 % and the third performance decreased by ↓15,7 % in comparison with the first performance with the apply of regeneration type DK. Time of the second performance decreased by ↓10,3 % and the third performance decreased by ↓26,2 % in comparison with the first performance with...

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

Effect of climbing time and recovery time on repeated bouts of climbing performance
Šimkanin, Martin ; Baláš, Jiří (advisor) ; Panáčková, Michaela (referee)
The objective of this research was to assess continuous and intermittent training load and its influences to a rock climbing performance. Fifteen (11 M and 4 F) experienced (7- to 9 RP, UIAA) sport climbers (age 24,1 ± 2,7 years, body mass 66,4 ± 9,8 kg, height 173,1 ± 7,7 cm, HRmax 197,5 ± 3,7 beats .min-1 ) were subjected to climbing test, which involved three exercises of continuous and intermittent load. The first exercise involved 30s of climbing and 30s of passive recovery, maximum 12 repetitions. The load and recovery time in the second exercise were doubled and in the third exercise subject climbed until exhaustion. The pace of climbing was assigned 25 movements .min-1 at negative angle 135ž or 120ž, owing to their present climbing abilities. All subjects refrained from exercising at least 24h between each testing. Significant differences in performance were found between intermittent and continuous load. Climbers achieved the highest performance (165,5 ± 45,4 steps; time of climbing 6:22 ± 1:44) during intermittent exercise 1. Worse performance (135,6 ± 80,6 steps; time of climbing 5:08 ± 3:02) was noticed in the second intermittent exercise. The worst performance (53,7 ± 14,9 steps; time of climbing 2:06 ± 0:32) among of all exercises was noticed during continuous load. Mean HRmax values...
