순발력 검사의 신뢰성 및 타당성에 관한 연구

Abstract

This study aims to verify the reliability of their internal conformity to verify the reliability and validity of power tests, having a doubt in current method of recording the higher score out of 2 trials. The focus of the study was on verifying the reliability of the difference in the number of trials which is part of the internal conformity by increasing the number of trial, and also on verifying the reliability mentioned above based on the assumption that there may be differences depending on the rest times. The target of this study was 25 students from H University, and they have been tested on 3 items of standing long jump, standing backward jump, and standing high jump. The following conclusions were reached from this test.

First, there was no statistically significant difference in the number of trials for standing long jump, standing backward jump, and standing high jump from once to 7 times.

Second, there was no statistically significant difference between rest times from 0 minute to 9 minutes.

Third, there was a statistically significant difference in the correlation of standing long jump, standing backward jump, and standing high jump with the number of trials.

Fourth, there was a statistically significant difference in the correlation of standing long jump, standing backward jump, and standing high jump with the rest times.

In conclusion, it is considered that if the jump was performed in maximum expression at first trial, trying again does not make any big difference. In addition, it is considered that giving a set rest time is pointless in power test. The correlation between 3 items of power test is at a very high level, therefore, it is decided that they are useful as power test.
