Stress fractures in endurance runners and their causes
Hlaváčová, Tereza ; Červinka, Pavel (advisor) ; Feher, Jan (referee)
Title: Stress fractures in endurance runners and their causes Objectives: The objective of this bachelor thesis is to identify possible corelation between stress fractures of Czech female endurance runners and their menstrual cycle irregularities, changes in training intensity, reduced energetic intake as well as changes in body regeneration. Methods: Qualitative research was carried out using the survey method with means of non-standardised, anonymous questionnaire. The results were further processed and evaluated using MS Word and MS Excel applications. Results: The results of the research led to the conclusion that a corelation can be detected between stress fractures of female endurance runners and their menstrual cycle irregularities, changes in training intensity, reduced energetic intake and impaired regeneration. The highest degree of co- occurrence was observed with increased training intensity. The next most common connection to stress fractures was found with menstrual cycle irregularities, followed by changes in body regenerations and decreased energy intake. Keywords: Endurance running, female runner, stress fracture, menstrual cycle, the female athlete triad

Effect of asymmetric load on the stereotype of running.
Holíková, Dana ; Pánek, David (advisor) ; Satrapová, Lenka (referee)
Title: Effect of asymmetric load on the stereotype of running. Objectives: The aim of this experimental work is to evaluace the electromyographic activity of selected muscles when running without load and with load on the treadmill, and the co- current assessment of the impact of asymmetric load on the lateral weight distribution. Methods: Six recreational runners underwent the experiment during which we monitored electrical activity of m. deltoideus pars anterior, m. trapezius pars ascendes et descendens, lumbar paraspinal muscles, m. gastrocnemius lateralis and m. tibialis anterior while running without load and with load on the periphery of the upper right extremity. For the experiment a motor treadmill at a constant speed of 10 km/h was used and a 0,5 l PET bottle completely filled with water was applied as the load. Changes of lateral weight distribution were assessed having investigated stance on two scales. The measured values were statistically evaluated. Results: Within the group of all the probands it was proved that there existed an impact on normalized average amplitude of EMG signal at left-oriented m. gastrocnemius lateralis. The hypothesis of the influence of asymmetric load on the lateral weight distribution was not demonstrated. Keywords: endurance running, surface...

Running shoe as a possible cause of injuries in endurance runners . from the perspective of a physiotherapist
Krchová, Zuzana ; Smolíková, Libuše (advisor) ; Čakrt, Ondřej (referee)
This work collects knowledge on running shoes and its potential impact on injuries in endurance runners in the theoretical part. There is a sought link between the running-related injuries, usually used running shoes and foot-strike technique. Then there are described the most common running related injuries and kinesiology of running. The practical part includes a study in the form of a questionnaire, which was attended by 383 runners. This research presents the results of the effect of footwear on running mechanics and the formation of overuse injury in endurance runners. The data obtained demonstrate injury in 48% of runners in the last 2 years. The most common site of injury is the knee joint. Runners usually resolve these problems having a rest. Endurance runners who buy frequently new shoes are more injured than runners who run in older shoes. Rearfoot-striking is associated with knee- pain, but it is not a higher risk of injury.

Endurance Running and Its Effects of men within the age group between 35 45 years young middle age
AJGEL, Lubomír
The main objective of this Diploma Thesis is to determine effects of endurance running on body weight reduction of men within the age group between 35 and 45 years young middle age. The theoretical part revealed interesting facts and compilations provided by various available resources related to the given issue and thus served as a basis for the elaboration of the practical part consisting in heart rate values obtained during several hours of endurance run. The impact on health of probands (tested men) was discovered while assessing heart rate, BMI values and anthropometric measurements of four skin-fold thickness by using skinfold calipers. The result revealed considerable reduction in body fat percentage rate as a consequence of endurance running which was proved as a convenient and recommended activity bringing many benefits to human health, such as reducing overweight of men within the aforementioned age group.
