The effects of live and video demonstration on the early acquisition of a New York task

Demonstration is a widely used method in sports teaching and coaching, as well in Physical education classes. The most commonly used types of demonstration live demonstration and video demonstration. However, a direct comparison between these two types of model has rarely been undertaken in a motor context. Therefore, the aim of this reseasrch is to specify and compare the effects of the two different metric protocol, former standard and the new video demonstration, on the estimation of the test results in the primary school.The participants involved the third and the fourth year students from four elementary schools in Petrinje and Sisak which territorialy belong to urban area of the Sisak- Moslavic county. The total number of students on whom this research has taken place was 327, of which 186 were boys and 141 were girls at the age of 10, 5. The students were divided into two subsamples considering the used treatment, both standard and video demonstration protocol. The sample of variables in this research consists of four tests for evauating motor abilities: Shuttle run, Back-save sit and reach for the right and left leg, Push-ups and Curl up. The use of video demonstration protocol for task performance has shown a significant effect in the tests Shuttle run and Curl up, while significant effects were not gained in both both flexibility tests (Back-save sit and reach for the right and left leg) and strength tests (push-ups) due to the protocol. The results indicated that video demonstration seems more effective than the live one for the early acquisition of a completely new motor skills.
