دراسة مقارنة في مقدار القوة الناتجة و النشاط الكهربائي لعضلات الأطراف السفلى بين اختبار القفز العمودي (سيرجنت)‎ و اختبار القوة القصوى

الملخص EN

The aim of this study is to identify the amount of explosive power and power by using force platform and maximum EMG during two different tests; max-force product for lower limps, and Sargent vertical jump test.

(8) youth power lifters were choice by deliberate way.

Each player have three attempt, then (24) the sum of samples, Researchers gain much of results such as the power product from Sargent test is not the absolute maximum power from legs, And the time had the great affect in determine amount of net force.

.The peak of EMG were nearby in each tests.
