The present study aimed to assess male and female Taekwondo (TKD) players based on four domains of World Health Organization Quality of Life (WHOQOL) -BREF and to find the dominant domain in TKD players' life. Forty-six (46) male and fifty-five (55) female participants were included in the study through purposive random sampling. The information on four quality of life domains, i.e., physical health, psychological, social relationship, and environment, were gathered through the WHOQOL-BREF Bengali version (WHO, 2020) questionnaire. The researchers analysied the data through descriptive analysis, ANOVA, LSD, and students' t-tests at 0.05 level of significance. The analysis revealed that irrespective of Gender, the social relation domain plays a dominant role in TKD players' life, and the male TKD players are better than their female counterparts in the physical health domain only. Based on the result, we concluded that regular practice and participation in the TKD program help the participant to develop all four aspects of WHOQOL-BREF. Among the four domains, the participants scored significantly better in the social relation domain in both gender groups. The interpersonal relations and interaction among the players during a practice session and competition may be the possible reason behind such kind of result. In the inter-group comparison, the male participants responded significantly better in the physical health domain than the female participants, possibly because of some physical and physiological gender differences.
