Kotrba, Milan ; Gryc, Tomáš (advisor) ; Šťastný, Petr (referee)
Title Ball flight control with wedges in amateur golf players Objectives The aim of the study was to determine level of ball's flight distance control and its relaitionship to the current and long-term performance of the elite amateur golfers. Methods The research sample was consisted of 10 selected right-handed golfers of the elite amateur level (age = 22 ± 3 years, height 186 ± 13 cm, weight 81 ± 20.5 kg, HCP 1,2 ± 3,4). Probands task was to hit 15 strokes. At each of the tested distances (45 m, 55 m, 65 m, 75 m and 85 m) the player played three strokes. The TrackMan 4 3D Doppler Radar (TrackMan, Denmark) was used to determine tested parameters. The results were recorded in individual protocols and then processed in Microsoft Excel, which was also used to obtain basic statistics: mean, standard deviation, variation range, and percentage deviation from the target. Percentage deviation from target was calculated as a percentage of total deviation from target distance. We used program R v3.5.2 (Vienna, Austria) for statistical evaluation of the relationship between ball distance control and performance. The relationship between the parameters was evaluated using the Pearson correlation coefficient. Results In the research it was found that players with lower handicap are mainly achieving better...

Benešová, Amálie ; Gryc, Tomáš (advisor) ; Prokešová, Eva (referee)
Title: Structural and functional asymmetry in golfers aged 12 - 18 Objectives: The aim of this study was to determine the level of body composition parametres, postural stability, muscle shortening and joint mobility of junior golfers and identify and analyze structural and functional asymmetry. Methods: The 14 golfers participated in this study (n=14, age 15,8 ± 1 year, body height 174,5 ± 10 cm, body weight 67,6 ± 13 kg and HCP 5,4 ± 5,9). Body composition including segmental muscle's weight distribution was tested on a bioimpedance instrument Tanita (Japan). Furthermore, the postural stability was examined on the Footscan (Balance 7.6 software) in 4 positions (USOO, USZO, FL_L and FL_P). The kinesiological analysis made by physiotherapist mainly tested muscle shortening and asymmetry using Janda's muscle function tests (1996). The dependence between the measured data was determined by the Pearson coefficient. Results: The average muscle's weight distribution was 2 % higher in the lower right leg, 3,1 % higher in the upper right arm compared with the left limbs. Asymmetry was also found in postural stability (average difference between stability on the right and left lower extremities was 25.9 %). Muscle shortening was found in more than 70 % of probands in hamstrings and quadriceps femoris,....

Title: Influence of different way of strength training on body composition, postural stability and muscle and explosive strength in Men's Physique and Street Workout Athletes Objectives: The aim of the thesis was to find out the level and the difference between the parameters of body constitution, postural stability and muscular and explosive force of upper and lower limbs with groups of Men's Physique and Street Workout athletes. Methods: The research sample was represented by two groups (Men's Physique competitors and Street Workout athletes). We assessed chosen parameters of body constitution by Tanita MC-980MA, postural stability by RS Footscan, explosive force (Kistler) and muscular force (Cybex Humac Norm and Takei A5401). Assessed parameters of body constitution were percentage of body fat and fatless matter. In the tests of postural stability, we assessed total travel way of the center of pressure (TTW) in chosen stands (open/closed eyes and one- leg left/right). When testing explosive force, overall produced maximal force and height of the leap were assessed. Muscular force of upper limbs was evaluated by produced force in kg and muscular force of lower limbs was assessed with the help of muscular force moment in concentric muscle activity with angular velocity 60ř·s-1.

Title: Influencing the success and accuracy of putting stroke using drill exercises Objectives: The aim of this study was to determine the influence of specific training conditions (short and long drills) on the success and accuracy of putting stroke of amateur golfers. Methods: Ten amateur golfers participated in this study (age = 35,0 ± 12,9 years; height = 176,7 ± 10,1 cm; weigth = 73,9 ± 17,7 kg; Hcp = 27,7 ± 13,4; game experiance = 4,2 ± 2,6 years). The design of this study consisted of data collection before training, a training session, and data collection after training. Before and after intervention each player made 10 putts from distance of 0,9 m, 1,5 m, 3 m, 8 m, 10 m a 12 m. During 4 weeks of intervention, the research file was divided into two grups (short and long drills). To determine the relationship between parameters success and accuracy, game level (hcp), game experience and training frequency was used Pearson's correlation coefficient (p < 0,05). To determine the statistically significant difference between the pre and post intervention test was used a paired t-test. Results: When evaluating all players together before and after intervention, we found higher success of short putts (by 11 %, p < 0,001) and higher accuracy of long putts (by 15,8 %, p < 0,001). A group of short...

Kunčická, Zlata ; Gryc, Tomáš (advisor) ; Carboch, Jan (referee)
Title: Load analysis of golf players Objectives: The aim of the study was to determine the load intensity of golf players, the comparison between players of different levels and determine the health benefits of the game. Methods: The theoretical part was processed thorough a study of scientific literature. Data were measured by sport-tester Garmin, which were then processed in the Garmin Connect and in Microsoft Excel. Was determined by calculating the maximum heart rate of the individual player and the results were compared qualitatively and quantitatively with the scientific literature. Results: Golf is a light to moderate aktivity of load amounting 62% of the maximum heart rate of the individual. Golf in conjunction with the movement on the field can have a positive effect on humans and prevent lifestyle diseases associated with hyperkinesis. During one eighteen-round of golf player conquers average of 10.5 km and reforge as 70% of the official length of the course. Professional players spend more time reading the terrain and planning launch, so they are moving more. Keywords: golf, heart beat, health, condition, golf field

Zerzán, Miloš ; Kokštejn, Jakub (advisor) ; Gryc, Tomáš (referee)
Title: The relationship between motor performance and body composition in football Author: Miloš Zerzán Head of work: Mgr. Jakub Kokštejn, Ph.D. Aim: To determine the current level of motor performance and somatotype among football players (9-10 years old). To determine the relationship between motor performance (evaluated by UNIFITTEST 6-60) and somatotype among football players at older mite team (9-10 years). Methods: Total sample was consisted of 25 players who underwent anthropometric measurements to determine the somatotype according to the method of Heath-Carter and UNIFITTEST 6-60 for the evaluation of basic motor performance. Results: It was found that 72 % of the tested players achieved above-average evaluation in UNIFITTEST 6-60. The tested football players had a lower portion of subcutaneous fat considering the physical constitution. In our study we did not find significant relationship between selected indicators of motor performance and physical somatotype. Although the level of motor performance was rather above-average and the value of subcutaneous fat was relatively low, our results suggest that these determinants of individual game performance are not closely related. Key words: motor skills, somatotype, UNIFITTEST 6-60, physical fitness, children, football

Miřátský, Petr ; Gryc, Tomáš (advisor) ; Jebavý, Radim (referee)
Title: Possibilities of influencing the lower limbs force in fire sport competitors Objectives: The goal of the thesis is to find out the level of force and explosive force in chosen fire- sportsmen's lower limbs and to verify the possibilities of influencing its level with the help of a specific plyometric training. Methods: The research group consisted of fire-sportsmen whose level of muscle force and lower limbs explosive force was explored with the help of entrance tests. To find out the level of the lower limbs muscle force we used the Cybex machine, the level of the explosive force was tested on the Kistler force boards. We assessed muscle force of knee flexors and extensors, which was evaluated with the help of the moment of muscle force (circular motion) in a concentric muscle activity at an angular velocity 60ř·s-1 . In explosive force, we assessed maximum force and upward leap height produced. After the entrance tests the sportsmen went through an intervention programme consisting of a specific plyometric exercise. This intervention programme was concluded with an output testing, which was identical with the entrance one and the aim of which was to find out the current level of the parameters assessed. Results: The result of the thesis is a record of a muscle force and a lower limbs...
