Abstract
The research aimed at realizing the relation ship between the achievement of speed run (30m & 80m) and some aspects of mascular strength such as; strength equation, explosive strength and speed distinguished strength. The researcher has applied the descriptive for its convenience with the nature of the research. Tests were used to obtain standard data, simple correlation coefficient and contribution ratio to obtain findings as follows : 1- A significant correlation has been proved between the achievement of (30 m run) legs’ explosive strength and arms’ speed-distinguished strength. 2- A significant correlation has been shown between (80 m. run), legs’ explosive strength, arms’ speed distinguished and strength of the abdomen. 3- No significant correlation has been found between 30 m. run achievement and strength endurance of the abdomen muscles. 4- Legs’ explosive has obtained the highest contribution rate % 47 followed by % 28 for the arms’ speed-distinguished strength %15 for the strength endurance of the abdomen muscles in 30 m. run achievement. 5- Legs’ explosive strength has obtained the highest rate % 40 followed by % 26 for the strength endurance of the abdomen muscles and % 21 for the arms’ speed-distinguished strength in 80m. run achievement.
