Building A Better Football Player

Four years of college football can shape a player into something bigger and better than he was when arriving at that first training camp. A study published in the Journal of Strength and Conditioning Research illustrates the body composition changes of 57 Division I players as measured each March.
 
On average, body fat percentage decreased 1.3% while players built up 6.2 pounds of lean mass in the course of one year. Over 4 years, body weight increased by an average of 14.5 pounds including 9.4 pounds of muscle. These patterns were similar for both linemen and other positions.
