The main purpose of this study was to examine effects of strength training on specific physical fitness qualities and skills performance in team handball in the case of Dembecha handball players. To put this in to effect, experimental research design was used. To collect datan, 30 male handball players were selected randomly and divided in to two equal groups as EG and CG by the means of randomization. Both groups participated in pre and posttest of physical fitness and handball skills. Muscular strength was measured using standing long jump and medicine ball throw test; muscular endurance using 10x 40m run test ; speed by 35m run; power through vertical jump test; shooting accuracy using spot shot test; dribbling performance by means of 30m dribble and 10x40m dribbling test; throwing power using power throw test; and jumping power via long jump shot test. Data collected from the participants were analyzed by paired t- test using Spss software version 23 with level of significant 0.05. The result showed that strength training has positive effect on muscular strength, muscular endurance, speed, power, dribbling performance, throwing power and jumping power in EG(p<0.05). But in case of shooting accuracy, no significant change were observed in both groups (p>0.05). Furthermore, no significant difference were found in all of the variables in CG (p>0.05). Based on this finding, it can be concluded that twelve weeks speed strength training has positive effect on muscular strength, muscular endurance, speed, power, dribbling performance, throwing power and jumping power, but not on shoot ing accuracy. Therefore, it is recommended that handball players and coaches should include strength training in their training sessions so that significant improvement of physical fitness and handball skills can be seen.
