Summary. Objective: In this study, the effects of 8 weeks of core training by gender on strength, muscle endurance, flexibility, dynamic balance and body composition was examined. Methods: Twelve females (F) (Age: 20.66 ± 1.82 years, height:165.96 ± 6.98 cm, body weight: 53.25 ± 7.11 kg) and twelve young males (M) (Age: 20.75 ± 2.63 years, height:172.38 ± 4.48 cm, body weight: 67.40±8.05 kg) participated voluntarily for the study. Body composition compartments, Y balance test (YBT), flexibility tests, isometric strength, back endurance, and sit up tests were tested before and after the core training of 3 days per week for 8 weeks period. "Two repeated measures” (group x time) was used for differences of pre- and post-training for all parameters at two groups. Results: The findings of the present study showed significant increases in all parameters, except body composition between pre and post-training results in both groups. However, between genders, there were not statistically significant differences all parameters except dynamic balance. Following the training, female group achieved more increase in percentage change of leg strength (+16.38%), back strength (+15.07%), Biering-Sorenson test (+38.65%), sit and reach test, spine ROM test, and posteromedial balance results. Differently, the percentage change of male group results for sit up (+37.94%), right-left lateral flexion (+16.40%, +17.03%), and anterior-posterolateral balance tests demonstrated increased more. Conclusions: This study investigated differences the effects of core training with unstable surfaces by gender on the physical fitness parameters. The results showed that gender does influence dynamic balance parameter but not body composition, flexibility, strength and muscular endurance parameters for 8 weeks of core training.
