ANALYSIS OF CENTER OF GRAVITY WITH THE PERFORMANCE OF ELITE LONG JUMPERS
Abstract
The relationship was carried out to study takeoff's center of gravity with elite
long jumpers' performance. For this research, ten male long jumpers of Manipur national level and
University level from the track and field match practice in different groups able to perform more
than 4 meters, first purposively as the subject from match practice long jumper and then randomly
selected the 10 subjects according to best performance for the study and their range of age was
between 19 to 25 years. Pearson's product-moment correlation was used to determine the
relationship between the center of gravity at takeoff and the performance of the long jump. For
testing the hypothesis, the level of significance set at 0.05 was employed with the help of the
statistical IBM SPSS-20 version, where it was hypothesized that there might be a significant
association between the center of gravity at takeoff and the performance of the long jump. For this,
through the segmentation method, the center of gravity was determined to see the association with
the performance of the long jump. After applying product-moment correlation, the obtained value
of correlation (i.e., r=1.000 and -.231) for 7 degrees of freedom, only the height of the center of
gravity at takeoff of the subjects was greater than the required value of 0.666 at 0.05 significance
level. The center of gravity of height of takeoff has exhibited no significant association with the
performance of subjects at takeoff. Therefore, the research study revealed that there is a significant
relationship between the center of gravity (height of cg of the body) and the performance of the
long jump.
