Batters may achieve dramatic increases in home runs through steroids
Date:9/19/2007

MEDFORD/SOMERVILLE, Mass. -- Steroid use by a Major League Baseball slugger may produce only modest increases in muscle mass and bat and ball speed but still boost home run production by 50 percent or more, according to a new study by Tufts University physicist Roger Tobin.

Tobin, a specialist in condensed matter physics with a long-time interest in the physics of baseball, will publish his paper "On the potential of a chemical Bonds: Possible effects of steroids on home run production in baseball" in an upcoming issue of the American Journal of Physics.

As Tobin's paper notes, Babe Ruth's record of 60 home runs in a single season stood for 34 years until Roger Maris hit 61 homers in 1961. For the next 35 years, no player hit more than 52 home runs in one season. But between 1998 and 2006, players hit more than 60 home runs in a season six times. Barry Bonds hit 73 home runs in 2001topping Maris' mark by an astonishing 20 percent.

According to Tobin, the explosion in home runs coincides with the dawn of the "steroid era" in sports in the mid-1990s, and that surge quickly dropped to historic levels in 2003, when Major League Baseball instituted steroid testing.

While the increase in home runs has been clouded by suspected use of performance-enhancing steroids, many have wondered why home-running hitting would be particularly vulnerable to performance enhancement. They have also asked if it is even physically and physiologically plausible that steroids could produce effects of the magnitude observed. The answer to both questions, says Tobin, is "yes."

Home Runs Disproportionately Affected

"A change of only a few percent in the average speed of the batted ball, which can reasonably be expected from steroid use, is enough to increase home run production by at least 50 percent," he says. This disproportionate effect arises because home runs are relatively rare events that occur on the "tail of the range
