Predictors of Physical Fitness in a College Sample

Abstract

The present study examined the relationships among self-reported amounts of exercise, body composition, age, weight, blood pressure, and physical fitness. Participants reported their duration and frequency of exercise, which were combined to obtain individual indexes of exercise. V̇O₂ max predicted from a 1-mi. walk test, percent body fat via sum of skinfolds, blood pressure, and flexibility of the lower back and posterior thigh were measured. Findings indicated that age and exercise index were significant predictors of fitness for women, and percent body fat was a significant predictor for men. Results suggest individuals' exercise index moderately correlates with fitness, although it is not the only contributing factor.
