The impact of sport climbing on anatomic structure and functional attributes of human feet
FIKEJSOVÁ, Veronika
The theme of this bachelor´s thesis is a study of the impact of sport climbing on structure and functional characteristics of the foot. The aim of this thesis is to compare the structure and functional characteristics of the feet of people that actively pursue sport climbing with the feet of people that do not. In the theoretical part of this thesis is briefly described climbing in all of its forms including sport climbing. There are also described functional anatomy and kinesiology of the foot, including kinetics and kinematics and basic information about proprioception. In the practical part are introduced probands that participated in this study. There are two groups of five probands. One group is comprised of active sport climbers, one group of non-climbers. There are also summary and comparison of all the data and results obtained during examinations. Final characteristics of the foot of climbers are in comparison with non-climbers rather positive. It turned out that the group of climbers has better characteristics in functional attributes of the foot, strength of the foot arch and symmetry of both feet. On the other side the group of non-climbers has better outcome in the flexibility and range of motions in selected joints.

Doktorová, Anežka ; Baláš, Jiří (advisor) ; Bačáková, Radka (referee)
Title: Effect of caffeine on finger flexor performance in sport climbers. Objectives: The goal of this work was to assess the effect of caffeine on the performance of the finger flexors during the all-out test in sports climbers. Another goal was to determine maximal strength in measured participants. Methods: 8 climbers (7 in the age 20-25 and one 34 years old) completed 3 experimental conditions during three laboratory visits to evaluate the effect of caffeine on finger flexor performance. The first was a control measurement and then, in random order, caffeine in the amount of 5mg/kg and placebo. Participants did a maximal strength test, a force gradient test and a 4-minute all-out test. Results: The maximum force reached an average of 49,0 kg during the control measurement, the total force impulse was 3889.6 kg.s, the critical force was 16,6 kg and the fatigue index was 68 %. After caffeine supplementation, the maximum strength values changed to 50,6 kg on average, for the force impulse to 3898,5 kg.s, the critical strength reached 15,7 kg and the fatigue index 69,1 %. The standard deviation of maximal strength shifted from 9,4 kg to 9,5 kg, the total force impulse from 684,4 kg.s to 717,5 kg.s, the critical force from 4,0 kg to 5,1 kg and the index fatigue from 6,2 % to 7,4 %.

Zýková, Eliška ; Baláš, Jiří (advisor) ; Hráský, Pavel (referee)
Title: The effect of Wim Hof breathing method in relation with sport climbing performance in all-out test Key words: sport climbing, hyperventilation, breathing exercise Objectives: The study is aimed to determine if there is an impact of Wim Hof breathing method on power performance of finger flexors during intermittent load. Methods: The thesis was made as an experimental study with ten volunteers, who are active sport climbers. They filled-out questionnaire and gave their consent to participate in the study. After that, they went through the all-out test of finger flexors twice. One time they did Wim Hof breathing method before their performance and one time they didn't. This succession was determined by random selection. The results of both tests were compared and assessed by Student t-test. Results: The main outcome value, work impuls, didn't vary. The impuls without previous Wim Hof breathing method was 4477 ± 14,3 kg.s and with Wim Hof breathing method 4385 ± 13,8 kg.s. There was only one outcoming value from the all-out test, which was varying on level of significance α = 5% (the repetitions of critical force). None of others 10 figures from the all-out test didn't vary. The Borg rating of perceived exertion didn't vary as well. Conclusions: This diploma thesis didn't confirm that Wim Hof...

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...

Effect of climbing ability on energy expenditure of climbing
Kodejška, Jan ; Baláš, Jiří (advisor) ; Malý, Tomáš (referee)
The aim of the study was to evaluate the relation between climbing performance and energy demands while climbing through a specific submaximal test. The sample consisted of twenty-six climbers (age 26,8 ± 3,3 years, weight 70,6 ± 6,2 kg, height 177,6 ± 6,5 cm). Climbers were deliberately chosen so that their performance covers as much scale difficulty of UIAA (Union Internationale des Associations d'Alpinisme) as possible. The performance was given by the climbers currently the highest ascent in the style of RP (Red Point). Performance of these climbers ranged between 4 to 10 degrees UIAA. Climbers were subjected to submaximal climbing test, which lasted three minutes in one slope. They moved at a constant speed of 25 movements. min-1 on climbing route, already known in advance, the slope after 3 minutes changed from 90 ř to 105 ř. VO2 (oxygen consumption), SF (heart rate) and VE (minute ventilation) significantly correlated with climbing performance of RP (90ř, VO2, r = - 0,82; SF, r = -0,66, VE, r = - 0,77; 105ř, VO2, r = - 0,84; SF, r = -0,78; VE, r = - 0,80 ). Respiratory rate during submaximal climb was about 25 breaths. min-1, which refers to a link with a climbing speed. VO2 during submaximal climbing can be used to evaluate the economy of movement.

Title: Assessment of the activity of the shoulder girdle muscles during static period of climbing movement. Objectives: The aim of the study is to determinate the electromyographic activity of shoulder fixators during natural and corrected climbing grip. The second aim is to compare this activity between the group of climbers and nonclimbers. Methods: The research involved 6 people, 3 climbers and 3 nonclimbers. The surface electromyography had been chosen as an objectification method. Measurements were perfomed during 4 static situation with two variants (natural and corected position). We tested these muscles: m. pectoralis major, m.sternocleidomastoideus, horní, střední a dolní část svalu m.trapezius, m.serratus anterior. The average amplitude normalizated to maximal voluntary contraction (MVC) was evaluated. Results: The significantly lower average amplitude was measured for the middle trapezius (18,4 ± 8,9 % MVC) in natural position (average of all positions) than in position corrected (35,3 ± 11,8 % MVC). For the lower trapezius, the average amplitude in natural position (30,1 ± 13,8 % MVC) was measured significantly lower too than in corrected position (61,7 ± 15,4 % MVC). Conclusions: The measurement results showed that, the EMG activity of the middle and lower m. trapezius was during...
