Abstract:
The purposes of this research were to study and compare the effects of flexibility and muscular strength training upon accuracy in football kicking. Forty subjects were purposively sampled from players of Assumption Sriracha College football team, ages ranged from 14 16 years old. Kicking performance was tested before the experiment and then all subjects were equated by kicking performance into four groups with 10 subjects in each group. First group was trained with only football kicking. The second group was trained with football kicking and flexibility training. The third group was trained with football kicking and strength training and the fourth group was trained with football kicking and flexibility training together with strength training. Each group trained for 8 weeks with 3 days a week. Accuracy in football kicking was tested after the second week, the fourth week, the sixth week and the eigth week, respectively. The results were analyzed in term of means, standard deviations, one-way analysis of variance and Scheffé method. The results showed that : 1. There was a significant difference of the average accuracy of football kicking in 15 metres distance within the third group between before and after eight week; in 20 and 25 metres distance, there was a significant difference of the average accuracy of football kicking within the fourth group between before and after 6 and 8 weeks, in 25 metres distance, there was a significant difference of the average accuracy of football kicking within the third group between before and after 2 weeks, at .05 level. 2. There were a significant differences of the average accuracy of football kicking in 15 metres distance between the third and fouth group and the second group after 8 weeks. In 25 metres distance, there was a significant difference of the average accuracy of football kicking between the fourth group and the first group after 6 and 8 weeks and there were a significant differences of the average accuracy of football kicking between the third group and the first group, after 8 weeks and there were a significant differences of the average accuracy of football kicking between the fourth group and the first and the second group, at .05 level. 3. The average flexibility within and between all groups were not significantly different after 8 weeks at the .05 level. 4. There was a significant difference of the average strength within the third group after 6 and 8 weeks and within the fourth group after 8 weeks. There were a significant differences between the third and the fourth group and the second group after 8 weeks, at the .05 level.
