The purpose of this study was to investigate the effect of concomitant administration of L-arginine and vitamin C supplements on improving athletic performance and physical activity in young athletes.
Design
A randomized controlled trial with a factorial, single blind, randomized controlled trial
Settings and conduct
Of the 72 athletes who applied to the Peugeot Club in August and September of 1977, they were given the number one form of cooperation, of which 48 filled out the form of cooperation and then selected the number form according to the criteria given to them. Two (medical-athletic records) were given to fill out and after filling out form number 40, 40 were selected and randomly divided into four groups of 10 supplemented (three groups) and placebo (one group).
Participants/Inclusion and exclusion criteria
Criteria for selecting the statistical population were at least one year of sporting experience, regular exercise and exercise three days a week, male only, age range of 25 to 28 years, no chronic and acute illnesses, no alcohol consumption and no smoking.
Intervention groups
The first group was supplemented with L-arginine, the second group with vitamin C, the third group with vitamin C, and the fourth group with placebo (glucose tablets).

Description
Body compositionIt has traditionally subdivided a two-part model of body weight into fat mass, which is the fat of all body reserves, including the brain, skeleton, and adipose tissue, and lean body mass (FFM) containing water, protein, and minerals. Fat scratches and fat bones divide. Given the complexity of manual computation equations and the need for high skill in subcutaneous fat measurement techniques and for increased ease of doing work in health and sports counseling centers, it is predicted that the body composition index will be calculated by a digital scales device. Good. The system uses a bioelectric resistance method to measure body fat. In this method the tester is placed on the device in such a way that the electrodes are in contact with his or her hands and feet. Then a relatively weak electric current passes through his body and the resistance to the current is measured. The electrical resistance is directly related to the percentage of body water, which is the highest in fat tissue. It can be calculated and when the total body weight is determined, using the various formulas already given to the device, body composition indices (fat percentage, etc.) are digitally displayed on the plate. The display will be displayed.

Description
Exercise performance is a combination of desirable genetic traits, motivation, training and proper nutritional practices. Athletes gain competitive advantage and achieve a higher level of health or physical performance of any type of diet or synthetic dietary supplement or drug. There are unfortunately a bunch of bad information in the area of sports nutrition. Athletes can benefit from nutritional training and interventions to raise awareness, self-efficacy and improve diet. Some of the relevant fitness factors Health and Exercise Using a Station Exercise Program L is different movements in the West, we measured body builders.

Method of measurement
They were then placed on the treadmill and measured by electrodes for heart rate and displayed on the screen. After 15 minutes of running on the treadmill and general body warming to measure flexibility using the flexibility box provided. We measured individuals in centimeters. We used the lacquer test to measure the equilibrium, and the individuals record was measured in seconds. Long jump test was used to measure power and the record was measured and recorded in cm. To measure the strength of a maximal repetition in the motion of Holter and Scott Foot Holter presses were used. To measure endurance the number of movements performed in one minute in the breech and abdominal movements (lying and sitting) and Swedish swimming were measured in terms of number. After six weeks of supplementation, the same tests were performed again and the records were recorded. Taken.
