The relationships between selected sprint specific bounding exercises and sprint performance were analysed using fourteen sprint athletes (7 elite performers, 7 sub-elite performers). Subjects were required to perform sprints over 60m, Counter Movement Jumps with and without loading (20kg), High Speed Alternate Leg Bounding over 30m and High Speed Single Leg Hopping over 20m. All athletes were subject to anthropometric measurement (Height, Weight and Leg Length). Of all variables measured, the Elite group were significantly better (p<0.001) in Counter Movement Jump, Time to 60m, Time from 30m to 60m and in their Maximal Running Velocity. Linear regressions were carried out on all variables that correlated with Time to 30m (Acceleration Phase) and Maximal Running Velocity at both the pO.OOl and p<0.01 level of significance. This allowed several prediction tables to be compiled that had performance measures (sprints and jumps) that could be used as testing measures for sprint athletes to determine their Acceleration Phase and Maximal Running Velocity. A stepwise multiple regression demonstrated that Time to 60m was the best predictor of Maximal Running Velocity. Time to 60m, Leg length, High Speed Alternate Leg Bounding and Sprint Stride Rate were the best predictors of the Acceleration Phase. A Stepwise cross-validation linear discriminant function analysis was used to determine the best predictors from both sprint and jump measures that would distinguish an athlete as an elite or sub-elite performer. From sprint variables, Time to 60m and Time to 30m were the two variables that best placed a sprint subject in either the Elite or Sub-elite group. From the bounding variables, Counter Movement Jump and the Ground Contact Time of the High Speed Alternate Leg Bounding were the two variables that best placed a sprint subject in either the Elite or Sub-elite group. The present study suggests that Time to 60m is the best predictor of Maximal Running Velocity and Acceleration Phase. Counter Movement Jumping and High speed Alternate Leg Bounding are also useful tools in developing and testing elite sprint athlete performance.

Title: Strength of knee extensors and flexors as a determinant in performance of speed abilities in youth Objectives: To find out whetherthere is a correlation between the strength of the knee flexors and extensors and the performance in speed tests in a selected age group Methods: There was a laboratory and outdoor testing carried out with a group of 42 students. The results were processed in tables and graphs, the arithmetic mean and the standard deviation functions were used Results: The tests showed that the more powerful the knee flexors and extensors are the better the performance in speed tests is. The hypothesis proved right, there is a strong relation between the knee flexors and extensor strength and a speed performance. The flexors scored higher in the importance for a speed performance than the extensors Keywords: Speed, strength, testing, youth, performance

The assessment of strength and power and the relationship of these measures to functional variables such as speed and vertical jump ability are understood poorly. This is particularly the case when dealing with a long-term preparation for a major event in a sport such as women's soccer. The results of this research suggest that a number of isoinertial speed strength measures may be sensitive to aspects of a training program and therefore be useful tools for determining the level of development of various underlying neuromuscular capacities. Further results provide a question mark about the role of maximum strength in the development of high velocity functional movements, as increases in maximum strength did not correlate to changes in measures of functional performance. An important finding from this research is the potential role of specific isoinertial speed strength parameters in the detection of neuromuscular fatigue. Time course analysis of the results in this study suggests that the use of these measures to detect fatigue warrants further investigation.

The aim of this diploma thesis was to measure the physical fitness of pupils from selected elementary school in Hradec Králové. From the obtained results iw was determined whether age has an effect on pupils'performance. Futhermore, the results were compared and on the basis of statistical analysis of the data a comparison of performances of 6th and 9th grade pupils and also comparison of boys and girls. The theoretical part focuses on the topics of a healthy lifestyle, physical activity, physical fitness, physical abilities, physiological and psychological specifics in older school children. The empiric part deals with statistical data processing and their evaluation based on the results in selected physical tests from the test battery called EUROFITTEST. Based on the results and their comparison, I came to the conclusion that in six of the total eight exercises, older pupils achieve statistically significant differences compared to younger pupils. When comparing the average results of 6th and 9th grade pupils, I found that in seven out of eight tests, 9th grade pupils achieve better results than 6th grade pupils. In the end, I found that the boys performed better on average in five tests out of eight. Girls achieve better results on average in one test out of eight. There are no differences in...

Thesis title: Stimulation of strength, speed and coordination abilities in the ice hockey goaltender. Aim of the thesis: To describe theoretical basis of stimulation in ice hockey goaltenders. To design a model of goaltender's strength, speed and coordination training and to find suitable methods, means and forms of the stimulation of strength, speed and coordination abilities focused on youth teams and older goaltenders. Method: Qualitative analysis of document contents was used to identify the main theoretical basis of stimulation of goaltenders strength, speed and coordination abilities. Determiners of goaltenders' strength, speed and coordination development were described on the basis of deeper analysis. The main theoretical resources were finally integrated into a logical complex by the method of synthesis. On this basis the conception of strength, speed and coordination abilities stimulation could have been set up and suitable methods, means and forms of the goaltenders' strength, speed and coordination training could have been chosen with focus on youth teams and older goaltenders. Results: The thesis discusses the topic of stimulation of goaltender's strength, speed and coordination abilities, describes the basic theoretical basis and determiners of goaltenders' strength, speed and...
