Effect of strength training on performance in triathletes
Halamka, Marek ; Jebavý, Radim (advisor) ; Krupková, Dominika (referee)
Title: Effect of strength training on performance in triathletes Objectives: Goal of bachelor thesis is to compare performance parameters between two groups of triathletes. The first group will add strength training to their ordinary endurance training and the second group will continue without strength training. Methods: A crossover design experiment was chosen in which the ES and KS swapped in the middle. The experiment lasted 6 weeks with a TJ frequency of 2-3 per week. The TJ content was aimed at developing whole-body strength endurance in amateur triathletes in the preparatory period. All probands completed entry, control and exit testing where I compared the results of strength training with and without strength training. Results: Results from this work indicated that the inclusion of strength-oriented TJ in endurance athletes resulted in greater gains in fitness tests compared to endurance training alone. Furthermore, the improvement was greater for ES 1 who received the intervention in the first phase of the preparation period than for ES 2 with the intervention later in the preparation period.

Marková, Kristýna ; Jebavý, Radim (advisor) ; Krupková, Dominika (referee)
Title: Effect of strength training on posture in triathletes aged 30-45 years Objectives: To examine the effect of incorporating strength-endurance training on posture in triathletes aged 30-45 years. Methods: Effect of strength-endurance training 2-3 times a week for 6 weeks on posture in triathletes. Thirteen amateur triathletes (3 women, 10 men) were selected for the research. After the input testing, the triathletes were randomly divided into groups ES 1 (n=8) and KS 1 (n=6). This was followed by a 6-week intervention programme for ES 1 that added 2-3 training units per week to their normal training activities. During this period, KS 1 was only allowed to do their normal training activities (no strength training). After the control testing, the groups were switched and KS 1 became ES 2 and 6-week intervention programme started for this group. During this period, ES 1 continued with normal training activities but was not to allowed to continues with strength training. The research was completed with output testing ES 2 and ES 1. For the assessment of posture in triathletes a set of tests was used which consisted of Body posture assessment by Jaroš and Lomíček, selected DNS (dynamic neuromuscular stabilization) tests by Kolář, selected tests of hypermobility and movement stereotypes by Janda....

Ťuka, Jeroným ; Baláš, Jiří (advisor) ; Krupková, Dominika (referee)
Title: Effect of caffeine on local isometric performance of fingers in sport climbers. Targets: The aim of this study was to investigate whether caffeine affects local isometric finger flexor performance in sport climbers during a 4 minute all-out test and the maximal force test. Methods: 12 climbers participated in the testing during 3 visits to the LSM laboratory at the UK FTVS. During each visit, they completed a maximal strength test, a force gradient and an all-out test on a specific dynamometer. During the second and third testing we randomly administered caffeine or a placebo to the climbers and monitored whether there was a change in performance. Results: The average maximal force during the initial measurement was 48.8 kg (σ = 12.5 kg), with caffeine supplementation the average maximal force increased to 48.9 kg (σ = 11.5 kg). The average total work during the initial measurement was 3573.3 kg.s (σ = 810.2 kg.s), with caffeine supplementation there was an increase to 3700.8 kg.s (σ = 865.7 kg.s). The average work performed above critical strength during the initial measurement was 1242 kg.s (σ = 726 kg.s), with caffeine supplementation there was a decrease to 1215.2 kg.s (σ = 456.1 kg.s). The average critical force during the initial measurement was 15 kg (σ = 5.9 kg), increasing to 15.9...

Běhounek, Michal ; Baláš, Jiří (advisor) ; Krupková, Dominika (referee)
Title: Effect of caffeine on rate of force development of finger flexors Objectives: The goal of this study is to assess the effect of caffeine on rate of force development of finger flexors. Methods: 10 hobby sport climbers (7 men, 3 women in age 20-34 years) during 3 visits of laboratory submit specific test to evaluate rate of force development of finger flexors. First measurement was the control one, in other two they were suplement by amout of 5mg/kg caffeine or placebo, in random order. The participants were measurement also for maximal strengh and and 4minutes all-out test. Results: Maximal speed of contraction in control measurement was in average 170,1 ± 54,3 kg/s. After suplementation of caffeine the average rises up to 190,9 ± 43,3 kg/s. The placebo average value was 156,9 ± 60,9 kg/s. Paired T-test does not confirm any significant differences between control measurement and measurement after caffeine suplementation. Conclusion: Results shown that caffeine does not affect the rate of force development of finger flexors. Key words: sport climbing, rate of force development (RFD), climbing dynamometer

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...

Bohadlo, Antonín ; Krupková, Dominika (advisor) ; Gajdošík, Jan (referee)
Title: Relationship of critical slope as an indicator of maximum metabolic steady state and climbing performance. Objectives: The aim of the diploma thesis is to find out the relationship between the critical inclination in the graded climbing test until exhaustion and the maximum performance of RP. Methods: The test involved 28 individuals (18 men and 8 women), aged 30.32 ± 8.23 years for men, 26.17 ± 2.82 years for women, performance on the scale of the Union International des Associations d'Alpinisme (UIAA) 8 men and 7 + / 8- women. Climbers underwent a graded climbing test to a subjective maximum and 3 times with a certain inclination until exhaustion. Based on a graded test, an estimate of 3 additional tendencies to exhaustion was determined. The resulting values were obtained in a formula that gave us the values of the critical slope. Subsequently, we plotted the results in two graphs and determined the correlation coefficient between the maximum slope and the difficulty of Red Point (RP) and the correlation coefficient between the critical slope and the difficulty of RP. Results: Based on the performed experiments, it was found that between the maximum slope and difficulty RP, the achieved slope is strongly negatively correlated with the value of RP (r = -0.62; p = 0.001) and within the...
