Many people used to run up in the morning workout, or before meals, fasting movement, and some even believe that this is the most effective weight loss, they think: Under normal circumstances 20 minutes before exercise, mainly carbohydrates as energy is consumed, over 20 minutes later, the fat will be utilized as a second energy up. When the morning after waking up, because during sleep as carbohydrates have been consuming a lot of energy, if this exercise, body fat as the first energy can immediately burn up fat burning that can shorten the time before, so you Running the same time lose more fat.
1, A foreign study confirmed that fasting exercise can promote fat consumption
In fact, studies show that foreign countries have a fasting campaign for the promotion of fat consumption is effective, but the mechanism is not the above mentioned time by fat mobilization. ClinicalBispebjergHospital, asics womens running shoesCopenhagen, Denmark, Department of Physiology L. H Enevoldsen’s 2005 study shows that exercise in starvation than postprandial exercise will enhance the movement and lipid metabolism after exercise, the movement of fat tissue decomposition rate, catecholamine concentration increases insulin concentration ratio reduction is a more important determinant. Leuven University, Belgium Wim Derave et al.2007 recruited seven years with metabolic syndrome 45 year old male, respectively, they do not exercise in the morning, fasting and postprandial vigorous exercise vigorous exercise three states glucose and insulin responses were investigation. The results showed that fasting movement state postprandial fat oxidation rate is higher than the state of motion, but the mechanism is unclear. Found in the current literature, did not find a conclusion supported by the result of the low carb fat mobilization shortened.
2, fasting exercise for health hazards
On the other hand, if the carbohydrate reserves are insufficient, the need for energy and proteins involved in oxidative synthesis of glucose. asics gel kinsei 4 running shoes Generally, proteins for energy in motion relatively small proportion, Cathcart study in 1925 showed that the protein can account for the movement of energy consumption 10%. And Chen Jidi, Yang Zeyi. Jiao Ying, etc. 1982 athletes protein metabolism and requirements study found that when the body glycogen depletion, amino acids for energy can rise to 10-15%. Proteins as nutrients, the main body is constitutive ** material basis of tissue cells can promote growth and development, metabolism in the body to form antibodies, enhance immunity, provide energy not its main physiological function. asics gel noosa tri 7 running shoes Decomposition of proteins involved in energy supply if excessive, will cause serious consequences, causing slow growth, decreased muscle composition, and even affect the immune system. Therefore, in daily life and movement, we should try to avoid protein degradation.
In summary, fasting movement’s role in promoting fat metabolism, but fasting movement may also cause protein degradation, affecting the body’s normal physiological function.
3, the correct way of exercising
1, to avoid completely fasting movement, keeping the body certain carbohydrate levels. If it is to get up early or before meals, may wish to add some sugar water or energy bars, in order to maintain blood glucose levels in sport.
2, the process of movement should always pay attention, if there is the phenomenon of dizziness, hasten to add sugary sports drinks to keep blood sugar stable and athletic ability.
3, if you exercise after eating, asice gel noosa tri 8 runnning shoes you should select at least 2 hours after a meal, such as gastrointestinal digestion of food basically stable, and then start moving.
4, the movement of fat metabolism is affected by many factors, including: fat mobilization, transport of fatty acids in plasma, fatty acids from the blood into the muscle cells of the process, the decomposition rate of intramuscular triglycerides and decomposition, the activation of fatty acids its transport across the mitochondrial membrane process. clearance asics shoes Among them, the fatty acid transport across the mitochondrial membrane carnitine transport system need. If you want to lose weight for the purpose, may wish to add the right amount of L-carnitine before exercise. Recent studies have shown that carnitine supplementation safe, effective, need to be properly combined with exercise can play a role in weight loss better. There are many domestic and international studies have shown that L-carnitine supplement before exercise for weight loss has a positive effect.
