Description
Amino acids are the building blocks of all body proteins , including structural proteins that build muscle, connective tissues, bones and other structures, while supplying the body with the nitrogen essential for the growth and maintenance of all tissues . Branched – chain amino acids are crucial to an athlete’s recovery and muscle t issue repair following strength competitions such as body building and powerlifting, and other anaerobic and aerobic exercises . † Leucine, isoleucine and valine work synergistically together and are responsible for supporting muscle protein synthesis , and promoti ng st rength and muscle enhancement. † In the human diet, leucine naturally occurs in greater amounts compared to isoleucine and valine ; as such, it is believed that an effective branched – chain amino acid (BCAA) supplement includes a higher ratio of leucine. Human studies show high leucine supplementation including isoleucine and valine result in a greater muscle protein synthesis response during recovery.
Male athletes were supplemented with BCAAs or a low – carbohydrate drink for eight consecutive days. BC AA supplementation increased the plasma BCAA concentration during exercise, whereas plasma BCAA concentration decreased in the low carbohydrate group. These findings suggest that BCAA supplementation may enhance endurance exercise capacity. † In a second randomized controlled trial, BCAA supplementation increased nitrogen retention, which reduced the loss of lean muscle tissue during resistance training. † According to researchers, BCAAs may be beneficial as an endurance and muscle recovery aid, and support immune function during athletic performance. † BCAAs may also be useful in delaying mental fatigue in endurance exercise.
PEAK ATP ®
Within the cell, adenosine – 5’ – triphosphate (ATP) is known as the major source of cellular energy. Extracellular ATP and it s metabolites support a variety of biological processes , including cardiac function, neurotransmission, liver glycogen metabolism, muscle contraction and blood flow. During exercise, ATP is released from human red blood cells when oxygen is low in a working muscle region. As a result, vasodilation occurs and increases blood flow to the muscle. Increased blood flow assists in the delivery of oxygen and nutrients to the cell and supports tissues in the body. Human and animal studies show ATP supplementation increases blood flow following exercise.
Peak ATP® is the only oral form of ATP shown to improve body composition and athletic performance. Peak ATP® is readily available and increases circulating ATP levels , provides a direct source of energy to the muscle, and improves post – exercise blood flow and recovery. It appears to achieve this by buffering fatigue during exercise and increasing skeletal muscle blood flow, thus enhancing muscle oxygen recovery. In addition , extracellular ATP directly supports t he synthesis and release of nitric oxide (NO) and prostacyclin (PGl2) within skeletal muscle , and , as a result , directly supports tissue vasodilation and blood flow. Peak ATP® has been studied in a resistance – trained population . The results demonstrate 400 mg of oral ATP supplementation for 12 weeks reduced protein breakdown and significantly increased muscle mass, strength and power.
