The analysis of speed of softball throwing

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,...
