To perform high press, Revs players must ingest the calories

FOXBOROUGH — Think back to April 1989, when Sports Illustrated wrote a several-page spread about the Packers’ first-round draft choice that year, lineman Tony Mandarich. At one point in the story, the magazine went into great detail about his personal grocery list which, as one might expect, would feed an army battalion.

For a lineman, the calories Mandarich had to inhale in order to perform are upward of 4,000 per day. That’s a lot of chow.

For a soccer player conditioned to run for eight to nine kilometers over the course of two hours? Believe it or not, it’s not too far off from that — especially when the players perform in a system which generates a lot of energy, much like the system Brad Friedel has instituted with the Revolution this season.

In the months leading into this year, Friedel brought Anton McElhone to Foxborough as the club’s head of fitness, which is an all-encompassing title — including looking after the players’ diets. McElhone, a Glasgow native who studied sports with exercise science at the University of the West of Scotland as well as obtaining a master’s in strength and conditioning from the University of Edinburgh, served in that capacity while the Revs gaffer played at Tottenham Hotspur FC in North London.

Since coming aboard, McElhone has carefully crafted the Revs’ dietary plans, and has done so in a way that takes into account not only the player’s positions but their hereditary backgrounds, as well.
