Abstract:
The effects of sex and competitive status (athlete vs nonathlete) on ankle inversion-eversion range of motion was investigated. 62 collegiate athletes and 36 collegiate nonathletes, both male and female, were tested. Analysis of variance showed significant (p<.05) main effects for sex but not competitive status or sex x competitive status. These results imply that college age women have more ankle rotational range of motion than men and that collegiate athletes in a group of various sports do not differ in ankle range of motion when compared to college nonathletes. Power in this sample did not permit definitive assessment.

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.
