PREDICTING MUSCULAR CAPACITY OF ARMS FROM DISTANCE OF HORIZONTAL THROWING OF MEDICAL BALL

The medical ball horizontal throwing test is one of the optimal tests to measure explosive strength and capacity. However, results of the test are not accurate because they use the meter as a measuring unit while strength measuring unit is the Newton and capacity with the Watt. Our knowledge of these variables makes us near to feel strength that was produced to make the ball reach this distance. These real units help us estimate components of loads including intensity, size and relief. Therefore, this study came to show the meaning if each term and how terms are connected mechanically in order to enhance scientific information of the researchers and follow modern measuring and testing methods. The study aims to: 1- Determine some biomechanical variables that affect medical ball horizontal throwing. 2- Determine the percentage of participation of explosive strength that affect medical ball horizontal throwing. 3- Finding the equation of predicting throwing level with significance of the explosive capacity of the medical ball horizontal throwing test. Population of the study was determined among some players of Koya University teams in the following games: (basketball, volleyball and handball). Number of players was 13 players selected purposively. The researcher used one (1) video camera (model: Casio-High Speed-Exilim) made in Japan, with a speed of 210 photos/sec. The researcher also used the medical ball throwing test (2 kg) using hands from sitting on a chair position. Among the most important conclusions found by the researcher, there were: 1- The watt unit can be predicted based on distance (in meters) in the medical ball throwing test. 2- Capacity is not the only biomechanical variable that affects throwing distance at medical ball horizontal throwing, but there are other variables which also affect and can be predicted.
