Proteins are essential. They are one of the main nutrients which help form the structure of the body. After water, Protein is the most important substance inside us. Ultimately it is an essential nutrient and there is no life without protein. Proteins contain four calories per gram and are the building block of human and animal structure. The average person requires 0.8 to 1.0 g/Kg of body weith per day  Whether active adults have increased protein needs compared to their sedentary counterparts is a source of controversy. Because resistance training and cardiovascular exercise induce beneficial muscular and structural damage and protein helps the muscles and tissues to repair and rebuild themselves, the American Dietetic Association,Dietitians of Canada, and the American College of Spots Medicine recommend that endurance athletes consume about 1.2 to I.4 g/kg of bodyweight, whereas strength-trained athletes consume up to 1.6 to 1.7 g/kg. However, a study by the Institute of Medicine (IOM) concluded that the evidence for increased requirements for active individuals was not compelling and suggested that 0.8 g/kg of bodyweight per day was appropriate for athletes. Please note that it is advisable to not take advice on supplement consumption from trainers and to seek advice from a medical professional. ———————————————– Info by : Dr Alireza Nikoo ———————————————– – Sports supplement consultant – Director – Medical Team at Oxygen Group. – Key member of Iranian Marshall Arts Federation Medical Team – Committee Member of the Education and Treatment Team of the Iranian Sport Medicine Federation
