In the world of American football, there is a stigma that players need to increase their overall body size to make an impact on the field. But, new research from a Grand Valley State University movement science professor and one of his students suggests that being bigger doesn't mean being better -- or healthier.
Jeffrey Potteiger, professor of exercise science, and Maggie McGowan-Stinski, senior athletic training major, set out to determine how body size has changed in college and professional football players over the past 70 years.
"We started to take a look at providing the information that sports medicine personnel need to be aware of in order to effectively protect the health of the players under their care," Potteiger said. "In football, the most at-risk athletes are the offensive and defensive linemen."
The research duo determined that players have gained an average of between a quarter of a pound to one-and-a-quarter pound per year since 1942. This equates to an average 60-pound increase in body mass for offensive and defensive linemen.
Potteiger said the most common diseases resulting from excess body mass and body fat, especially around the abdominal area, include high blood pressure, diabetes, cardiovascular disease and metabolic syndrome. He added that hitting the gym and eating more aren't the only ways athletes are attempting to gain body mass.
"The use of growth promoting agents, such as anabolic steroids, growth hormones and insulin carry side effects that range from mild to severe," Potteiger said. "The severity of the side effects is dependent on the dosage level of the growth promoting agents and the length of time the agents are consumed."
To help athletes increase their body size in a healthier manner, Potteiger recommends the following:
