to develop the performance of men athletes of short distance of Tirunesh Dibaba Athletics Training center in Asella. The study followed a true-experimental design. 30 male athletes divided randomly in to experimental and control groups (n=30; 18.30 ± 0.98 years, 1.772 ± .056cm). The treatment group passed through 8 week of intervention. It was conducted 3x30”seconds – 1:30” minutes for each different core strength exercises [1’ & 2’ recovery time between each exercise]; intensity 75- 90% and frequency 3 days per week. The Statistical Package for Social Sciences (SPSS) used to interpret the data and analyzed the collected data in quantitative methods. During week 0 and 8 each subject complete two assessment tests for both groups. According to independent t-test result the intervention group show significant performance improvement of 150m speed endurance, at post-test (M = 16.52, SD = 0.51) with t (28) = -4.97, p = 0.000; 400m sprinting (M = 50.50, SD = 1.50) conditions; t (28) = -4.17, p = .000, and core strength plank test (M= 5.40, SD = 0.71) condition, t (28) = 6.29, p = .000 demonstrated significant difference and better peak flow scores than the control groups in 8th weeks. The main finding of this study was that core body strength training can significantly improve speed endurance, sprinting, core strength ability and consistency of developed performance of short distance runners of Athlete Tirunesh Dibaba Athletics Training Center. The overall improvements of mentioned variables of the sprinters were significantly changed with the eight-week core strength training program. Key words: Core strength, Sprinting and performance
