Abstract
The relationship between grip strength, book load, and observed book-carrying mode of male and female college students was studied in a natural setting utilizing 350 subjects. It was found that male and female book-carrying modes were significantly different, but that book weights carried by the two sexes did not differ significantly. Male and female grip strengths were significantly different. A chi square analysis further examined the relationships between the four variables. While the relationships that interact to determine the dimorphism observed in book-carrying styles are complex, this study suggests an approach account for the differences observed.
