Abstract

The purpose of this study were to determine the effect of testing posture and elbow position on grip strength. Two hundred college students 100 males and 100 females aged 18 to 28 years, participated in the study. A Grip-Strength Dynamometer was used to measure the grip strength in two testing posture(sitting and standin) and four elbow position$(0^{\circ},\;45^{\circ},\;90^{\circ}\;and\;135^{\circ}\;flexion)$ correlations and t-test was used to determine any significant difference in grip strength between the testing posture and the elbow position. The results were as follows : 1. The grip strength was affected by testing pasture and flexion degree of elbow. 2. The grip strength was stronger in the standing than sitting in subjects 3. The grip strength decreased according to elbow flexion increase in subjects. 4. The higher grip strength gained in the standing with the elbow 0 flexion. 5. The grip strength by elbow flexion degree showed significant difference at sitting and standing posture. The grip strength was significant differenced by testing position at same elbow flexion degree.
