This study aimed to compare the effect of resistance training systems (Drop sets) and (Super sets) on some body and physical measurements and kinematic variables in (50m) front crawl swimming stroke, The experimental method was used, And the study sample consisted of (8) students from physical education students registered in swimming course level (2) who were divided into two equal experimental groups. The first group consisted of (4) students involved in a drop sets resistances training system program, and the second experimental group consisted of (4) students involved in a super sets resistance training system program. The duration of each program was (8) weeks, (3) training units per week. It was measure the average of the length and frequency of stroke arms and the speed of (50m) front crawl swimming stroke, The results of the study indicated that there were no statistically significant differences at the level of α ≤ 0.05 in the post measurement between the Drop sets and the Super sets on some kinematic variables in (50m) front crawl swimming stroke, It was apparent differences improvement higher for the Drop set system than the Super sets system in the average length of the arms strocks and velocity in (50m) front crawl swimming, the researcher recommended to use the drop sets system when teaching and training on skills that need strength, strength endurance and speed, such as front crawl swimming stroke among students of the faculty of physical education.
