Problem: The purpose of the study was to determine which of two methods of centering a football over distances of eight and thirteen yards is more efficient insofar as accuracy and speed are concerned. Procedure: A total of fifty-six high school sophomores were equated into two groups by the Iowa-Brace Test. One group was taught the one- hand method of cantering a football and the other group was taught the two-hand method. Each group underwent a six--week training period. After the training period, each individual was tested for speed and accuracy of centering a football. The distances over which the tests were administered were sight and thirteen yards. The accuracy teat was given by using a concentric circle target. The target consisted of six concentric circles, the largest being seven feat in diameter. The smallest was two foot in diameter. The remaining circles increased one foot in diameter from smallest to largest. The speed of each snap was timed with an Athletic Performance Analyzer. The machine measured the snaps in hundredths of a second. The data accumulated from the tests were analyzed and a t-ratio was computed. The coefficient of correlation was also computed to determine the relationship between accuracy and speed for both groups. Findings and Conclusions: The findings of the study were as follows: 1. The mean scores for the two-hand method were all better than the mean scores for the one-hand method. 2. The two-hand method was better than the one-hand method for accuracy at eight yards distance. The difference between the means of the two groups was significant at the five per cent level of confidence. 3. The two-hand method was better than the one-head method for speed at eight yards distance. The difference between the means of the two groups was significant at the five per cent level of confidence. 4. The two-hand method was better than the one-hand method for accuracy at thirteen yards distance. The difference between the means of the two groups was significant at the five per cent level of confidence. 5. There was no significant difference between the two methods for speed at thirteen yards distance. 6. There was a low coefficient of correlation between accuracy and speed for both groups at the eight and thirteen yard distances. For the population sampled under the conditions described, the findings suggest the following conclusions: 1. The two-hand method of centering is better than the one-hand method of centering. 2. A small relationship existed between accuracy and speed at the eight and thirteen yard distance.
