Abstract

Abstract: Aim: to analyze data and results of female judokas in Tokyo Olympics 2020 to identify the chronological age of younger / older judokas and its relation with results in all the seven weight categories in the Olympic Games. Methods: The researchers used the descriptive (survey) approach. Research community included data and results of female judokas (n=192) who participated in Tokyo Olympic Games 2020, held from 24 to 31 July 2021, representing (128) countries in (5) continents. Researchers used female judokas dates of birth and “DATEDIF” equation in “Microsoft Excel” to calculate chronological age of female judokas (day – month – year) on January 1st 2020. Results: younger judokas won (118) matches (55.40%) on the following weight categories: (-48) kg (58.06%) – (-52) kg (62.50%) – (-57) kg (53.57%) – (-70) kg (74.07%) – (+78) kg (66.67%). Older judokas won (95) matches (44.60%) on (-63) kg weight category (61.67%). Chi2 results indicated statistically significant correlation between age and results on P ≤0.05 in favor of younger judokas on (-48 kg - -54 kg - -70 kg - +78 kg) weight categories. Another statistically significant correlation between age and results on P ≤0.05 in favor of older judokas was shown for (-63) kg age category. No statistically significant correlation between age and results was shown for neither older no younger judokas on (-57) and (-78) kg weight categories. T
