bodybuilders are prone to zinc depletion or deficiency for a number of reasons. First, one of the best sources of zinc is red meat. Many bodybuilders eat a reduced amount of meat, concentrating instead on chicken and fish as their main protein sources. Second, bodybuilders lose more zinc than do non-exercisers. Zinc exits the body in a number of ways, including through sweat. On an exercise day, an athlete will lose 50% more zinc through sweat than on a non-exercise day. Third, bodybuilders require significantly more zinc than do non-exercisers. In fact, because bodybuilding involves the infliction of a great deal of micro-damage to cells and tissues that must be repaired, and because the muscle are stimulated through exercise to grow, the director of BALCO Labs estimates that bodybuilders may require up to twice as much zinc as do non-exercisers. This means that if you are a bodybuilder, you are very likely to have either a zinc depletion or deficiency. And if you are using steroids, which depress the body's zinc, magnesium and copper levels, you are even more likely to be zinc deficient. |
