The sample consisted of men and women between the ages of 20 and 57 years. In the men's group, the body height has restricted in 160–200 cm. And the women group the body height is restricted from 146 to 181 cm. And the HGS measured is limited between 10 and 75 kg. The standardized handgrip strength was obtained from the Ordinary least square and using the z-standardized residuals (M = 0 SD = 0.96).
