Abstract:
The purpose of this research was to compare the effects of speed bounding and harness running on acceleration ability among 14-16 years old male sprinters. The subjects were 20 male sprinters from Bangkok Sports School. They were chosen by purposive sampling method and divided into two groups by simple random sampling. The first experimental group was speed bounding group while the second experimental group was harness running group. Both experimental groups trained two days per week for a period of eight weeks. The data of acceleration ability from starting line to 10 metres 20 metres 30 metres 40 metres and 50 metres were taken before the experiment, after fourth and eighth weeks of training. The obtained data were analyzed in term of means, standard deviation, t-test, one-way analysis of variance with repeated measure and multiple comparison by the Tukey-a method were also employed for testing the statistical significance.
The results were as follows :
1. After fourth and eighth weeks of the experiment, the speed bounding group showed the better acceleration ability from starting line to 10 metres, 20 metres, 30 metres, 40 metres, and 50 metres than harness running group at the significant level of .05.
2. After fourth and eighth weeks of the experiment, both speed bounding and harness running groups showed the better acceleration ability from starting line to 10 metres, 20 metres, and 30 metres at the significant level of .05. However, the harness running had no significant increase of acceleration ability from starting line to 40 metres and 50 metres. Whereas the speed bounding group showed the increase of acceleration ability from starting line to 40 metres and 50 metres at the significant level of .05.
