THE EFFECT OF USING RUBBER ROPES TO IMPROVE SPEED-STRENGTH FOR UPPER LIMBS AND THE ACHIEVEMENT OF JAVELIN THROW

The study aimed to identify the effect of using rubber ropes to improve speed-strength for upper limbs and the achievement of javelin throw. The period of experiment last (8) weeks, three times per week. The sample consisted of (50) males, which divided into two groups control group (25) and experimental group (25). Paired t-test was used to find the different between pre and post tests for each group. Independent t-test was used to find out the different between control and experimental groups. The results showed that, using rubber ropes had a significant influence on improving speed-strength and achievement in post tests between both experimental and control groups.
