Abstract
Documented changes in height (cm) body weight (kg) and body composition (% fat) of college and professional football players from 1942 to 2011. Articles identified from data bases. Data were categorized into groups (college and professional). Player positions were grouped into linemen offensive backs and skilled. Linear regression provided slopes and 95% CI. Unpaired t-tests were used. Significance set at p < 0.017. College players in all positions have significantly increased body weight over time (95% CI lineman .338-.900 kg/yr; offensive backs .089-.298 kg/yr; skilled .078-.334 kg/yr). The college linemen showed a significant increase over time for height (95% CI .034-.188 cm/yr) and body composition (.046-.275 %fat/yr). Increases in body weight over time were found for professional lineman (95% CI .098-.756 kg/yr) and offensive backs (95% CI .180-.545 kg/yr). Body weight of all college players and professional linemen and offensive backs have increased during the past 70 years.
