The overall objective of the project: determining the amino acid glutamine supplementation on indices of muscle damage after eccentric resistance exercise in untrained men. Methods: this study is experimental subjects young male student volunteers normal weight (BMI between 19 and 25) University of Applied Sciences are Persepolis sport activities, dietary supplements, not drugs and painkillers and diet plans follow a specific pattern. In the case of the 7 days before the test, each of the above criteria are not respected subjects excluded from the study. A week before the test and after completing health questionnaires and consent form, the subject during a meeting with the means and methods of measure are introduced. At the same session, making Weight and height which, as the record of the meeting and recorded in knee extension subject to. Prior to the training program to measure fasting subjects index case (the enzyme creatine kinase ) cc 5 of venous blood from the forearm to get , motion range as measured by a goniometer and also muscle pain perception index by 6 -point scale (PAS) Shylaja (2003 ) will be evaluated, subjects drank his drink for 30 minutes after eating , then start doing the exercise protocol to damage to the muscle . Supplement for 1 / 0 g glutamine per kg of body weight (Karen pharmaceutical company ) was combined with 300 ml of water and placebo groups Maltv dextrin ( Karen pharmaceutical company ) the amount of water used to be ¬ . Delayed Onset Muscle Soreness (DOMS) and muscle damage in the muscles of the lower body with the knee extended, with about 70% 1RM weights similar research project LarocheDain (2005) be cause [6] . 24 and 48 hours after eccentric activity, an index of blood (CK), plus perceptions of muscle pain and range of motion should be evaluated again making .
