Analýza rychlosti softballového hodu / The analysis of speed of softball throwingWeissová, Adéla January 2017 (has links)
Title: Analysis of softball throw speed Objective: The aim of the thesis is to compare the throwing speeds with different modifications - from a distance of 2 meters to the screen (without aiming), throwing at a distance of 18 meters after the ball has been caught from the air and the ground (throw to the teammate). Furthermore, the goal of comparing throw speeds in selected age categories of softball players (9-17 years). Methods: Measure the throw speed by radar and data processing in Microsoft Excel. Results: Speed of throws for individual modifications - the category of the oldest players recorded the fastest throw option with the aiming of the player after the previous capture of the ball from the air and after the previous ball was caught on the ground. These variations of the throw exceeded the throw speed without prior capture and also without aiming at the player. In contrast, for other categories, the fastest option was the no-aim goal. The results of the oldest age group therefore refuted the first hypothesis, but the results of other age categories confirmed the hypothesis. In the case of the second hypothesis - higher throw speed and processing when the ball is caught from the air compared to landing the ball - the results of the oldest and youngest age category confirm the hypothesis,...

Strategický plán rozvoje SK Joudrs Praha / Strategic Development Plan of the SK Joudrs PragueDobrá, Tereza January 2015 (has links)
Thesis name Strategic Development Plan of the SK Joudrs Prague Thesis objective The aim of this diploma thesis is to draw up a strategic plan for the development of Joudrs Prague softball team for the period form 1st October 2015 to 30th September 2018. Methods of work A qualitative interview with the club President, a qualitative interview with the sports manager of the club, an analysis of texts and documents, the SWOT analysis, monitoring, descriptive case study Results An analytic part of the diploma thesis was built on the descriptive case study as well as on monitoring which provided an insight into the internal environment of the club and revealed the opinions of SK Joudrs Prague club members. The included SWOT analysis was developed on the basis of interviews and the dependence among the most important points was summarised in the table. The choice of the strategy resulted from the SWOT analysis. The financial analysis of the club was set up with regard to the interview with the club President and relevant documents. Key words Strategic planning, strategic plan, sports club, SK Joudrs Prague, softball

Experimental Analysis of Protective Headgear Used in Defensive Softball PlayStrickland, John Scott 01 January 2019 (has links)
Every year in the United States, an estimated 1.6 to 3.8 million people sustain sports-related traumatic brain injuries (TBIs), with an appreciable number of these injuries coming from the sport of softball. Several studies have analyzed the impact performance of catcher’s masks within the context of baseball; however, virtually no studies have been performed on fielder’s masks within the context of softball. Thus, the main objective of the present work was to evaluate the protective capabilities of softball fielder’s masks. To better understand the injury mechanisms and frequency associated with softball head/facial injuries, epidemiological data from a national database was reviewed first. Results displayed “struck-by-ball” as the most frequent injury mechanism (74.3%) for all head/facial injuries with a large majority occurring to defensive players (83.7%). With further motivation, the present work focused on testing the impact attenuation and facial protection capabilities of fielder’s masks from softball impacts. Testing with an instrumented Hybrid III headform was conducted at two speeds and four impact locations for several protective conditions: six fielder’s masks, one catcher’s mask, and unprotected (no mask). The results showed that most fielder’s masks reduced head accelerations, but not to the standard of catcher’s masks. On average, they reduced peak linear and angular acceleration from 40-mph impacts by 36-49% and 14-45%, respectively, while for 60-mph impacts they were reduced by 25-42% and 13-46%, respectively. Plastic-frame fielder’s masks were observed to allow facial contact when struck at the nose region at high speed. Observed differences in impact attenuation across fielder’s mask designs further suggested influence from specific design features such as foam padding and frame properties. Overall, the results clearly demonstrate that head/facial injuries may be mitigated through the broader use of masks, while further optimization of impact attenuation for fielder’s masks is pursued.

Srovnání polonízkého a polovysokého startu / The comparison of standing and crouch startTalácko, Zdeněk January 2021 (has links)
Title: The comparison of standing and crouch start Objectives: Analysis of time differences in base running from the position of standing and crouch start. Another goal was to compare these starts in group of male sprinters and then to compare these starts with female softball players. Methods: Mainly document analysis was used in my diploma thesis. The author used both Czech and foreign sources. The foreign sources were mainly scientific researches, professional studies and articles from scientific journals. The issue was closely linked to running bases in softball, athletic starts and strenght training focused on thy dynamic component. Standing and crouch starts were then examined in detail. Results: It was found that the standing start compared to the crouch start enhances the results of female softball players by 0,06 s at the distance of 20 meters. The difference in the group of male athletes was only 0,01 s. Major differences were observed in female softball players already within the first 5 meters where the first time difference appeared. This difference was gradually rising until the end of the 20 m distance. Keywords: base running, running in softball, athletic start, three-point stance start, standing start, crouch start

Upper Body Posture and Pain in Division I Female Volleyball and Softball AthletesPlunkett Castilla, Brittany M. 25 August 2015 (has links)
Participation in athletics is a popular pastime and form of entertainment. Children often begin to specialize in one sport at a young age in an effort to excel, which increases physical stress and the potential for injuries. Athletes participating in overhead sports are at increased risk of upper body chronic injuries, in part because the shoulder is an unstable hypermobile joint. Posture may also be affected in these athletes because of the demands placed on the upper body. The purpose of this study was to measure the upper body posture in a sample of Division I collegiate volleyball and softball athletes to investigate the prevalence of postural abnormalities and their relationship to pain or injury.
Twenty-one Division I collegiate female athletes (seven volleyball; fourteen softball) who participated in their sport during the fall 2014 to spring 2015 seasons were studied. Athletes completed a pain and injury questionnaire, after which individual upper body posture measurements were made. Measurements included resting bilateral scapula position, head position, and shoulder position. An iPad mini camera was used with a commercial application (PostureCo, Inc.) to perform a photographic plumb line posture assessment with photographs taken in anterior, posterior, and lateral views.
Posture analysis revealed a high prevalence (85.7 %) of forward head posture in this sample. Forward shoulder was noted in 42.9 % of the athletes and abnormal horizontal scapula position appeared to occur more frequently in the dominant arm (71.4 %) than in the non-dominant arm (47.6 %). Chi square tests determined that there was no statistically significant relationship between posture abnormalities and self-reported pain in this group of athletes. Results of this study -- although preliminary -- should be used to inform future research to investigate potential relationships between posture and pain/injury in overhead athletes.
