What is the science behind ZMA?
Lome Brilla, Ph.D., a sports performance researcher at Western Washington University, recently reported that ZMA significantly increased free testosterone levels and muscle strength in NCAA football players. These ZMA study results were presented by Dr. Brilla on June 2, 1999, at the 46th annual meeting of the American College of Sports Medicine in Seattle, Washington. The findings were recently published in the official ACSM journal, Medicine & Science in Sports & Exercise, Vol. 31, No. 5, May 1999. According to Dr. Brilla, “A group of competitive NCAA football players who took ZMA nightly during an eight-week spring training program had 2.5 times greater muscle strength gains than a placebo group. Pre- and post-leg strength measurements were made using a Biodex isokinetic dynamometer.” The strength of the ZMA group increased by 11.6 percent compared to only a 4.6 percent increase in the placebo group. “The muscle strength increases may have been mediated by the anabolic hormone incre
