Abstract:
The purpose of the study was to find out the effect of resistance training on selected physical 
fitness components of Erer Woldeya secondary school male students. To achieve the purpose of 
the present study, 40 male students were selected as study subjects. The subjects were selected 
purposively and were assigned into two equal experimental (20) and control (20) group through 
randomly. The experimental group participated in individualized and supervise moderate
intensity resistance training program 3 days/week for 12 weeks. The control group did not 
participated in training program but the tests were conducted for both groups. The ages of 
subjects were ranged from 16-17 years. The collected data were analyzed by SPSS to determine 
the difference, if any among the adjusted post test means on selected dependent variables 
separately. In all the cases, 0.05 level of confidence was fixed to test the level of significance. 
The results showed that experimental groups were better performance on selected physical 
fitness components of Erer woldeya secondary school male students. The parameters selected 
for the study were: physical fitness (muscular strength, muscular endurance, and body 
composition) and Data were analyzed by using SPSS. The result of the study found that, 
muscular strength (9), muscular endurance (10.55), showed significant improvement of mean 
difference at (p<0.05). RM tests were analyzed by paired sample T-test and it was found that, 
push up test and sit up improved by mean difference of 53.25% and 36.37% respectively. Body 
composition did not show substantial alteration in statistically significant difference. However, 
an improvement of 7.1% was registered. There was no substantial significant improvement 
observed in control group. This study proved that resistance training program significantly 
improved selected variables.
