Abstract:
The study was conducted to investigate the effect of Circuit training program on muscular strength, flexibility and cardiovascular endurance: in case of Gibson youth academy female students, Bole sub- city Addis Ababa, Ethiopia. To achieve the purpose of the present study, 30 female students were selected asstudy groups with age ranges 16-17 years. Simple random samling techniques was used. The subjects were randomly assigned participated in circuit training for 12weeks i.e.3 days per week 40-50-minute duration per day. Pre, during and posttraining tests were conducted on health-related fitness variables such as cardiovascular endurance, strength, and flexibility. The data collected from the study subjectwere analyzed by using SPSS version 20 software. The data per training to health-related fitnesswere analyzed by paired sample t test to determine the difference between pre and post mean forparticipants. The mean value difference of push up increased by 6.07, step up decreased by 5.90 bpm and sit and reach test result increased by 4.93cmafter 12 weeks circuit training program. The result obtained in this study indicated that there wassignificant change in cardiovascular endurance, strength and flexibility. Based on this finding, it can be concluded that circuit training has positive effect on health related fitness females students. 12 week circuit training had significant effect oncardiovascular endurance and strength of females. The similar studies can be conducted with the same variables by selectingthe subject from other environmental aspect
