Implementing split training models is one of the most challenging criteria of exercise science due to the conflicting findings of different researches. The aim of present study was to compare four different split models of resistance exercise on body composition, strength and muscle circumference in trained women.
28 athlete students of university of Guilan with average age(22.10  2.04y), height(164.68  3.53cm), weight(62.90  9.45kg) and body fat percent(27.50  2.50) volunteered to participate in the study. Subjects randomly divided in to four groups of seven including: one session to four session per week for 8 weeks which dedicated to one to four split models respectively (S1, S2, S3, S4). Body composition variables including limb circumferences (arm, shin, Thigh), fat percent (triceps, abdominal, thigh) and upper and lower muscular strength in bench and leg press (Berzycki), were assessed befor and after 8th week of resistance training. Resistance training load started at 60% of 1RM and reached 80% of 1RM at 8th week. lnterset and lntraset resting periods respectively considered 60-180 and 60 sec with a tempo of 1:2 sec for all groups. Normal distribution of data was determined using Shapiro-Wilk test. One-way analysis of variance (2×4) was used to determine significant differences among groups. In the event of a significant F ratio, Bonferroni Post hoc test were used for pairwise comparisons. A criterion level of p< 0.05 was used to determine statistical significance.
The results of this study showed that, bench press in S1, S2 groups had significantly increased compared to pre-test (p< 0.05) as well as strength of lower extremities in all groups S1, S2, S3, S4 (p< 0.05). However, no significant differences in body composition, percent of body fat, circumference and strength of studied muscles observed between groups.
Conclusion: Since there was no significant difference between groups in all studied variables, as well as increasing strength in all four study groups, it can be acknowledged that exercises based on multi component models cannot be effective in enhancing the strength of athletes' body composition.
