摘要：The research objective is to find out how much power contribution of the arm muscles, arm length, abdominal muscle strength to throw away the inside. Test using survey research methods. Population used in this study were 20 players PS Untag Semarang. Data processing method using a statistical calculation. Prior to hypothesis testing, analysis of the tested conditions 1) test for normality using the Kolmogorov-Smirnov test, 2) homogeneity test using Chi-Square and 3) to test the linearity of the regression line to see the value of F, 4) Test keberartian model. Hypothesis testing with test regression analysis. The study is based on the calculation are: Power arm muscles less powerful, less influential arm's length, abdominal muscle strength and less powerful effect together is to throw away the rest in and influenced by other variables not included in the study. From the above results suggested the data in order to provide training to coach throw-in in a more effective, the throw-in player that can be improved in the exercise and the researchers and observers of football to do the research further by adding a variable that is estimated to have a more significant relationship, such as the throw technique , timing throws, flexibility and efficiency of motion movement.
