Brazilian Jiu-jitsu
Brazilian Jiu-jitsu, or BJJ, is a style of martial arts, modified from the ancient Japanese art of Jiu-jitsu by the Gracie family and others, based on using an opponent’s momentum and leverage against them for defense. It involves take-downs and grappling, and has become a large sport that can be seen incorporated in the televised sport Mixed Martial Arts, or MMA. BJJ is a high intensity sport that involves endurance training as well as resistance training and explosive power. There are two types of BJJ, either Gi or no-Gi, and matches can be different depending on someone’s fighting style. Points are awarded during the fight for maintaining dominant positions such as the mount, side control, and back. They are also awarded

They have higher levels of PPARβ/δ to increase fatigue resistance and act as a transcription factor to promote ‘slow’ genes. Slow twitch muscle fibers also have slow Calcium ATPase and lower activity myosin ATPase, which both work to cause longer contractions. Fast twitch, type II, fibers are the opposite of slow twitch fibers and involve more anaerobic activity. They have fast Calcium ATPase and High activity Myosin ATPase causing shorter, faster contractions. These muscles have three types; IIa, IIb, and IIx/d. Type IIb fibers are fast and glycolytic and while working out fatigue quickly; these are the muscle types that beginners usually have coming into BJJ. Type IIa fibers are also fast acting and glycolytic, but are better adapted to fatigue resistance and are present after training. Finally type IIx/d fibers are fast and glycolytic and have fatigue resistance between that of IIa and IIb …show more content…
Many things activate and inhibit the activity of this pathway. Rapamyosin and endurance training inhibit the activity of mTOR and therefore inhibit the formation of muscle proteins. IGF-1, Amino acids, and resistance training activate the mTOR pathway and promote the formation of muscle and ribosomes. During exercise it is speculated that the body has a mechanoreceptor to sense resistance training. This is said to be involved in the activation of mTORC₁ along with growth factors, IGF-1 and insulin, and amino acids from the Akt pathway. Endurance training releases high levels of AMPK in the muscle cell causing inhibition of the mTORC₁ pathway (Laplante& Sabatini, 2009). Ribosome formation is also promoted by mTORC₁ and transcribes proteins for the acquisition of muscle
