The effect of the menstrual cycle on performance in sports
Baumová, Nikola ; Šteffl, Michal (advisor) ; Soukupová, Vendula (referee)
Title: The effect of the menstrual cycle on performance in sports Objective: The aim of this study is to investigate the effect of the menstrual cycle on performance in sport using the results obtained from previous studies dealing with the effect of the menstrual cycle on performance in sport. Methods: This thesis was carried out as a systematic review. Sources of information were scientific articles and studies from the PubMed, Scopus, EBSCOhost and EBSCOhost databases and literature related to the influence of the menstrual cycle on sports performance. Results: A total of 45 studies were selected for this study (9 cross-sectional, 33 cohort and 3 intervention studies). A total of 3086 probands (2364 from cross-sectional, 644 from cohort and 78 from intervention studies) aged 18 to 35 years were included. Conclusion: In most cases, no effect of MC on sports performance was found. If any effect was observed, the worst phase of MC for performance appeared to be the mid-luteal phase, while the best was the follicular phase. Keywords: menstrual cycle, menstrual phase, follicular phase, luteal phase, strength, power, force, muscular performance, aerobic, aerobic power, aerobic capacity, endurance, endurance power, endurance capacity, anaerobic, anaerobic power, anaerobic capacity, athletic...

Effect of the load and recovery time on a physiological response in sport rock climbers
Šimkanin, Martin ; Baláš, Jiří (advisor) ; Vomáčko, Ladislav (referee)
Title: Effect of the load and recovery time on a physiological response in sport rock climbers Objectives: The main purpose of this study was to assess the inluence of various types of climbing loads on a physiological response in sport rock climbers. Methods: Seven experienced (8 to 9+, UIAA - Union Internationale des Associations d'Alpinisme) sport climbers (age 25,4 ± 7 years, body 64,8 ± 6 kg, height 175,8 ± 5,3 cm) were subjected to climbing test until exhaustion, which involved three excercises that included various types of load: continuous, intermittent with 30s load and 30s rest periods (test 30/30) and intermittent with 90s load and 90s rest periods (test 90/90). All subjects refrained from exercising at least 48h between each testing. The monitored variables were performance of climbing steps, heart rate (HR), oxygen consumption (VO2), minute ventilation (VE), energy expenditure (EE) and blood lactate (LA). Results: Peak values of monitored variables show that a climbing intensity was similar among all tests (HRpeak 168 ± 11 to 172 ± 7 bites/min, VO2peak 35,2 ± 4,7 to 40,3 ± 5,3 ml/kg/min, LA 4,1 ± 1,1 to 4,9 ± 1,4 mmol/l). EE was in average 9,0 to 9,8 kcal. Subjects climbed longest (4min 45s ± 37s) in the test 30/30 (six climbers achieved maximum defined time 10 x 30s), whereas total...
