Current scientific evidence suggests that when whole body vibration (WBV) is used as a warm-up prior to performing eccentric exercise, delayed-onset muscle soreness (DOMS) is mitigated and strength loss recovers faster. These benefits were observed primarily in nonresistance-trained individuals. The aim of this study was to determine if WBV could mitigate soreness and expedite strength recovery for resistance-trained individuals when used as a warm-up prior to eccentric exercise. Thirty resistance-trained males completed 300 maximal eccentric contractions of the quadriceps after warming up with (WBV) or without (CON) WBV. Both CON and WBV experienced significant isometric (27.8% and 30.5%, respectively) and dynamic (52.2% and 47.1%, respectively) strength loss immediately postexercise. Isometric strength was significantly depressed after 24 hours in the CON group (9.36% p < 0.01), but not in the WBV group (5.8% p = 0.1). Isometric strength was significantly depressed after 48 hours in the CON group (7.18% p < 0.05), but not in the WBV group (4.02% p = 0.25). Dynamic strength was significantly decreased in both the CON and WBV groups both at 24 hours (19.1% p < 0.001, and 16.1% p < 0.001, respectively), 48 hours (18.5% p < 0.01, and 14.5% p < 0.03), and 1 week postexercise (9.3% p = 0.03, and 3.5%, respectively). Pain as measured by visual analog scale (VAS) was significant in both CON and WBV groups at 24 and 48 hours postexercise, but the WBV experienced significantly less soreness than the CON group after 24 hours (28 mm vs. 46 mm p < 0.01 respectively), and 48 hours (38 mm vs. 50 mm p < 0.01). Pain as measured by pain pressure threshold (PPT) increased significantly in both groups after 24 and 48 hours, but there was no difference in severity of perceived soreness. The use of WBV as a warm-up may mitigate DOMS but does not appear to expedite the recovery of strength in the days following eccentric exercise in resistance-trained individuals.

Title: Influence of whole body vibration training on postural stability in selected sporting population Objectives: The aim of this study is to compare the influence of whole body vibration training on the stability of the human body and assessing the possibility of using this training method to improve postural stability in selected sporting population. Methods: 15 mainly beach volleyball players (athletes) were randomly assigned into two groups. Experimental group (n 8) in addition to their own training practiced twice a week on the Power Plate, while the control group (n 7) to continue the current practice of beach volleyball. The experimental group participated in a total of twelve units during the six-week exercise intervention. We reviewed the standard deviation and average values of COP displacements in the anteroposterior, mediolateral and overall direction of the COP path. For this purpose, we used pressure platform Footscan. Results: The results indicate a clear trend to improve postural stability at the beach volleyball player after a six-week intervention, whole body vibration training. Improvement was most noticeable in tests Flamengo (standing on one leg), in which the total COP path decreased for all probands at the right lower extremity and in six of the eight probands in the left...

Title: Power Plate Center's Marketing Communication Objectives: : The objective of this diploma thesis is to discover the present state of the marketing communication of the sport institute Power Plate Center in Jungmannova street in Prague both in the customers view and also in the view of the company itself. On the basis of the gathered data then evaluate, eventually suggest the improvement of the current marketing communication. Moreover, by the aid of this data also suggest the marketing communication aimed at view potential clients. Methods: The quantitative method of the data collection by questionnaire and the qualitative method of data collection with the help of the depth interview was used in this work. The results were illustrated by tables, texts and graphs. Results: After the evaluation of the results, several faults of the Power Plate Center's communication with their customers were found best. In the synthetic part some recommendations were made, which could lead it the improvement of this marketing communication. Keywords: Marketing communication, communication mix, marketing research, questionnaire, depth interview, Power Plate.

9 Abstract Title: Influence of Power Plate machine vibrations on m. levator ani contraction. Objectives: In my thesis I would like to follow up on my bachelor`s thesis in which I was analyzing the importance of exercise on the Power Plate machine from a theoretical point of view. I set the objective of my thesis, in co-operation with professionals in this area, to find out whether Power Plate machines have any impact on the pelvic floor contractions, especially on the m. levator ani. Methods: Theoretical part of my thesis was conducted using the research (exploration of facts) method. For theoretical input I mainly used my bachelor`s thesis which was being followed up with. Majority of studies regarding WBVT (whole body vibration training) influence on human body is available from foreign sources. The practical part of my research was conducted via the quantitative quasiexperimental method. The works was further performed with use of the explanation (empirical and generally theoretical) methods and interpretation methods. For the data analysis were used the basic descriptive statistics, analysis of variance with repetition with Geisser-Greenhouse adjustment and paired t-test. Interpretation method was used to generalize the research outcomes, to confront them with existing knowledge, and to debate their...
