HUBUNGAN KEKUATAN OTOT LENGAN BAHU DAN KELENTUKAN OTOT PUNGGUNG TERHADAP KEMAMPUAN LEMPAR LEMBING PADA ATLET PPLP PUTRA DISPORA RIAU

Abstract

Abstract: This study aims to determine whether there is a relationship between shoulder arm muscle strength and back muscle flexibility on javelin throwing ability in PPLP athletes Putra Dispora Riau. The sample from this study were 6 javelin throwing athletes. The sampling technique was taken (total sampling) or full sampling technique in PPLP Putra Dispora Riau javelin throwing athletes, amounting to 6 people. The results of the correlation in PPLP Putra Dispora Riau javelin athlete where the first analysis between shoulder arm strength X1 and Y where rtab at a significant level ɑ (0.05) = r_count (0.984) <r_tab (0.878), means the hypothesis is accepted and there is a moderate relationship between shoulder arm strength to javelin throwing ability at PPLP athletes Putra Dispora Riau. From the calculation of the analysis of both X2 and Y, where r_tab is at a significant level ɑ (0.05) = r_count (0.984) <r_tab (0.878), it means that the hypothesis is accepted and there is a moderate relationship between back muscle flexibility to javelin throwing ability at PPLP Putra Dispora Riau . The third analysis of the relationship of shoulder arm muscle strength (X1) back muscle flexibility (X2) with javelin throwing ability (Y) where rtab at a significant level ɑ (0.05) = r_count (0.984) <r_tab (0.878), it can be concluded that the relationship between ( X1) and (X2) with (Y) or the relation of shoulder arm muscle strength and back muscle flexibility to javelin throwing ability in PPLP Putra Dispora Riau athletes on moderate intervention.
Key Words: Shoulder Arm Muscle Strength, Flexibility and Throwing.
