Exercises With Different Ranges Of Motion With Significance Of Electrical Activity for Muscle in Strength With Speed Of Lower Limbs For Weight Lifters Of Physical Strength

Abstract

The aim of research is making exercises with three ranges of motion by electrical activity and know the effect in strength with speed for muscles of lower limbs. The sample contains weight lifters of Alsadiaa, sport club as advancer group in 2010-2011.The researcher uses experimental program that have contains three groups that consist pre-test and post-test. The period of experiment ten weeks as three units weekly. The researcher uses statistic mean (SPSS).The results , analysis and discussion are shown. The researcher concluded that exercises with three ranges of motion by electrical activity have significances effect in variable of strength with speed among pre-test, post-test and pre(with weight of pre) for test (leg press).The researcher recommended that new equipment's as (EMG) in supervised neuron variables before , during and after training. It is possible to make other research with upper limbs of body with other variables
