Abstract

The aim of the research is to identify the impact of SPD3 on some physical and numerical variables in butterfly swimmers
Research hypotheses:
1- There are statistical differences between the pre and post measurements in some physical variables and the numerical level of butterfly swimmers experimental research group.
2 - There are statistical differences between the pre and post measurements in some physical variables and the numerical level of butterfly swimmers control group.
4 - There are statistically significant differences between the mean of the two dimensional measurements in the experimental and control groups in some physical variables and the numerical level of the butterfly swimmers and for the experimental research group.
