Description
Studies in geriatrics have found that the second and fourth digit (of the hand) ratio (2D:4D), an indicator of in utero androgen exposure, shows significantly negative correlation with muscle mass (MM) and muscle strength (MS). In my thesis research, I examined correlations between 2D:4D ratio and the MM and MS of college students and compared the results to previous geriatric studies in order to evaluate 2D:4D measurement as a supplementary tool for understanding factors associated with muscularity. I evaluated college students using a scanning bed and calipers to determine digit ratio. I then measured calf-circumference, MM using bioimpedence technology and MS using a dynamometer for grip strength.
