Background: Considering the importance of core muscles hypertrophy and possible effects of core strengthening cycles in Cyclic Yoga, the aim of the present study was to investigate the effect of 20 weeks of Cyclic Yoga selected exercises on core muscles hypertrophy in adult women. The study was conducted in 1396 at international institute of Yoga Payam Mehr.
Materials and Methods: In the present semi-experimental study, 24 female participants were assigned as yoga group with at least 3 months of experience of yoga practice (N=15; 34.66± 6.68 y) and control group (N=9; 34.66 ± 5.09 y). Initially, an ultrasound sonography device was used to evaluate muscles thickness including Erector spine, Psoas and abdominal including Rectus, Transversus, Internal oblique, and External oblique. The Yoga group spent 20 weeks of selected Cyclic Yoga exercises, three times per week, one hour per session, and the control group did not have regular exercise during this period. At the end of 20 weeks of treatmnet, muscle thickness was recorded again using ultrasound sonography. Then, the percentage of the post-test changes, compared to the pretest changes within group and between group, was calculated and data were analyzed using independent t-test and Paired t-test, respectively. 
Results: The thickness of the abdominal muscles were increased significantly for Rectus (19.1%), Transversus (16.8%), Internal oblique (9/9%), external oblique (15/2%) and Psoas (9.3%), and Erector Spine Muscles (5/1%) in Yoga group compared with those of the control group. (P<0.001)
Conclusion: It seems that two core strengthening Cyclic Yoga style cycles have positive effects on hypertrophy of these groups of muscles.
