The effect of a high-intensity training program on BCL2 and BAX proteins and on sprint performance in young 100-m sprinters

The biochemical and physiological processes in the athlete's body play a significant role in preserving internal and environmental balance via functional adaptations of the internal organs when training. The objective of this research was to prepare a high-intensity training program in BCI2 and BAX proteins for young 100m sprinters and also to identify the effect of this training program on the BCI2 and BAX proteins and on sprint performance. The researchers used the experimental method with a pre- and post-test for its suitability to the nature of the problem. The study sample included 6 young sprinters from Wasit Governorate. For data analysis, the researcher used the Statistical Package for the Social Sciences (SPSS). The results of the study showed statistically significant differences between the pre- and post-tests results in the BCI2 and BAX proteins and sprint achievement in 100 m, in favor of the post-test (p < 0.05). In conclusion, the training program had an effect on the low level of protein BCL2 and on the high level of protein BAX, and the training program was also effective in developing the achievement test in young 100-m sprinters.
