E2G EAT TO GROW nutrition, supplements, must-haves and more You Say Tomato … By George L. Redmon, PhD, ND The surprising source of nature’s recently uncovered naturally occurring steroidal alkaloid. O ne of the trickiest factors to manage in training is the preservation of hard- earned muscle tissue. Fortunately, by combining the proper combination of macronutrients and timing them appropriate- ly, you can reduce or negate exercise-induced muscle breakdown. This, as you know, helps to kick-start or sustain the actions of specific physiological mechanisms that allow you to physically perform at a high level. Recently, researchers at the University of Iowa began looking at how various molecular structures whose messenger ribonucleic acid expression (mRNA), meaning signals they transmit, counteracted molecular mRNA signals that essentially amplified commands to accelerate human skeletal muscle degen- eration. As a reminder here, like DNA (your genetic blueprint), mRNA carries unique genetic codes in different series of patterns that relay messages to structures within the cell. Surprisingly, these researchers found that a naturally occurring compound called tomatidine heightened mTOR signaling, the primary anabolic pathway that regulates protein synthesis. studies indicate that tomatidine reduces skeletal muscle de- generation, enhances recovery, and stimu- lates skeletal muscle hypertrophy in both fast- and slow-twitch muscle fibers. 30 april 2017 | ironmanmagazine.com Tomatidine is a naturally occurring steroi- dal alkaloid (a substance found in plants), a by-product of alpha-tomatine. According to researchers at the Department of Chemistry and Materials Science at the Tokyo Insti- tute of Technology in Japan, tomatidine is found abundantly in tomato plants. Overall, these researchers noted that in addition to increasing skeletal muscle mTOR signaling, studies indicate that tomatidine reduces skeletal muscle degeneration, enhances recovery, and stimulates skeletal muscle hypertrophy in both fast- and slow-twitch muscle fibers. As a reminder here, fast-twitch muscle fibers are responsible for the speed of muscular contractions and essentially enhance the ability of a muscle to rapidly contract. These fibers could be described as the power-muscle fibers because they use anaerobic (without oxygen) metabolism
