Effect of pre-cooling on climbing performance in heat
Knap, Roman ; Kodejška, Jan (advisor) ; Baláš, Jiří (referee)
Title : The effect of local pre-exercise cooling on climbing performance in a hyperthermic environment. Objective: The aim of this work was to assess the effect of forearm precooling on climbing performance to exhaustion in a hyperthermic environment. Methods: The sample consisted of nineteen male participants aged 25 ± 6 years. The participants were selected from among the students of the University of Warsaw University of Technology according to a criterion selection (RP ≥ 6). Each participant underwent 3 laboratory visits. At each visit, he was put to the two graded tests on a climbing ergometer to local exhaustion, always using different procedures before the first and second tests (CWI15/PAS). The measured time to exhaustion (s) was used for performance evaluation. The effect of individual procedures on performance was evaluated using a paired T-test. Results: A significantly positive (P < 0.05) effect on climbing performance until exhaustion was found when using the CWI15 procedure before exercise. There was an average performance improvement (↑10.4%) compared to performance without precooling (PAS). When the CWI15 procedure was used between performances, a smaller natural decline in the second performance was found, and in most participants the CWI15 application even caused a significant...

Reliability of incremental exhaustive treadwall test
Procházková, Adéla ; Kodejška, Jan (advisor) ; Busta, Jan (referee)
Title: Reliability of a graded test on a climbing ergometer until local exhaustion Aim: The aim of this work was to determine the reliability of the test to local exhaustion on a motorized rotary ergometer for sport climbers. Methods: 19 male climbers aged 24.7 ± 5.8 years, with a body weight of 74 ± 7.5 kg and a height of 178 ± 7.1 cm took part in a graded test and retest on a Climbstation rotary ergometer for two weeks. Reliability was assessed by repeated measures analysis of variance (ANOVA). Results: Statistical results showed high consistency of measurements (ICC = 0.90). Statistical significance reached P = 0.054. The detected mean measurement error was evaluated at 20.5 s and the coefficient of variation reached 6%. Conclusion: The measured reliability indicates a high reliability of the test. Based on these values, the test can be reliably applied when testing climbers in sport climbing. Key words: reliability, climbing ergometer, graded test, sport climbing

Time characteristics of workload during climbing the same route on a climbing wall and treadwall
Maťochová, Šárka ; Baláš, Jiří (advisor) ; Gajdošík, Jan (referee)
Title: Time characteristics of the load when climbing the same path on an artificial wall and on a climbing ergometer Objectives: The aim of this work was to assess the time characteristics of the grip when climbing on a climbing wall and on climbing ergometer and to compare these results. Methods: Twenty female participants were divided according to their performance into two groups. Two identical routes were climbed- one on a climbing ergometer, the other on an artificial climbing wall. Climbing routes were 18 m long and were rated Grade 7 on the IRCRA scale. There were 45 grips used in total, the starting hand grip was 1.5 m above the ground. The profile of the climbed route was perpendicular (90 ř). The task was to climb the route in the specified time. Data were collected by making a video recording of the movement on the climbing wall and the climbing ergometer. To determine the time characteristics, video recordings were analyzed in Dartfish 10 software and the duration of the static and dynamic phases were assessed. Results: The total time of climbing on the ergometer was 258.0 ± 16.1 s for less advanced, 263.8 ± 4.4 s for more advanced. The total time for wall climbing was 273.4 ± 22.9 s in the less advanced group and 259.5 ± 18.4 s in the more advanced group. The mean time of static...
