This paper aims to determine the relationship of an external resistance training intervention programme on horizontal and vertical jumping ability of women volleyball players. It was an experimental study, and twenty volleyball players with a national school participation level were selected as the study sample. The age of the subjects ranged from fifteen to eighteen years. A pretest-posttest design and quasi-experimental design were used for the research. Players were exposed to a six-week training programme comprising combinations of squat, bench-press, overhead press, dead lift, and barbell row. Tools for measuring horizontal and vertical jumping ability were the sargent jump test, approach spike jump test, three forward jumps tests, and standing broad jump test. After analysis of the data, it was found that the external resistance training intervention programme significantly affected the horizontal and vertical jumping ability of women volleyball players. This research is useful for coaches, trainers and physical education teachers for practical application.
