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 for getting out of these positions with a sweep.. Matches are usually around five minutes long and can be quick paced anaerobic movements, slow calculated aerobic exercise, or a combination of the two. The round can be won by points or by submission such as a choke or joint lock. A fighter needs to be prepared for any kind of match, so training involves long periods of high intensity workout, stretching, resistance training, and technique repetition. Endocrine Response Beginners of this sport often find themselves out of breath and fatigued quickly and often don’t start with the physical capabilities needed for the sport. When beginners start training they quickly reach their VO2max, which stimulates a stress response and signals for Cortisol Releasing Hormone to be released from the hypothalamus, This hormone stimulates release of ACTH, Adrenocorticotropin Hormone, from the Anterior Pituitary which then leads to the release of Cortisol from the Adrenal Cortex. The release of this Hormone occurs quickly in beginners because of their low VO2max and begins storing fat, promoting glucogenesis in the liver, and protein breakdown in the muscles. Cortisol also reduces the uptake of amino acids and glucose into other cells allowing it to be available for use in the muscles for energy. Growth Hormone is another hormone involved in the Endocrine response of BJJ fighters and is released after a short period of exercise such as a five-minute match. After the match ends there is a small release of Growth Hormone and causes lipolysis, Sodium conservation, protein synthesis in muscles, and the release of IGF-1 (Insulin growth factor-1) from the liver. Lipolysis is involved in fat breakdown and beginners who are aiming to lose weight usually have shorter training sessions more often to promote this hormone release. The release of IGF-1 from the liver occurs to promote protein synthesis in the muscles by activating the MTOR pathway through …show more content…
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
