The purpose of this study was to determine the effect of combination specific resistance and ordinary swimming  training on Breaststroke swimming  performance in young boys. Twenty boys of Alborz  province  swimming team age of 13±1 years ,weight 50/ 65±1/02kg and height 159/8 ±4/91cm, participated in this study. After the initial testing of the performance variable (Fifty-meter record of Breaststroke swimming) , technical variable (stroke number) and  strength variable (strength of spinal extensor muscles), subjects were randomly divided in two groups, Experimental group (combination  specific  resistance and ordinary swimming  training) and control group(ordinary swimming  training).A week of familiarization training was performed to adapt with vest (specific resistance) and then training program were performed  for 6 weeks, three sessions per week .Training program consisted of 15minutes of warmup and 8 repeats of 50 meters breaststroke  with 1minute rest interval between repetitions, in exprimental group (with vest of training) and control group(without vest of training). At the end of the training, post test  was performed  in accordance with the conditions of the pre test.  Kolmogorov –Smirnov  test was used to determine normality of data distribution, Paired t-tests was used to determine within group changes and the covariance analysis was used to compare the progress of dependent variables between the two groups. The results of this study indicated that although swimming performance was significantly improved in both groups (p≤0.05) ,but there were no  significant differences between the groups in fifty-meter record of Breaststroke swimming,­ stroke number and strength of spinal extensor muscles (p≥0.05).It may be attributed to non-professional subjects or Low-intensity resistance training.
