The current research aims to identify the effectiveness of utilizing weight training to improve maximal muscular power of the arm and the digital record and its effects on some biomechanical properties of the arm in 100m freestyle swimmers. The researcher used the experimental approach (one-group design) with pre- and post-measurements. Research community included swimmers of Alexandria Swimming Zone (n=58). The researcher purposefully recruited (20) swimmers as (10) were chosen as a pilot sample while the other (10) represented the experimental group. Results indicated that: - The recommended weight training program had a significantly positive effect on the maximum muscular power of the arms of the swimmers (research sample).- The recommended weight training program had a significantly positive effect on the digital performance level of the 100-meter freestyle swim.- The recommended weight training program positively influenced the development of some mechanical properties of the arm in the 100-meter freestyle swim.- Weight training overcomes the speed deficiency resulting from traditional training, in addition to its nature being closer to the actual performance during swimming.
