Exercises According to Target Time and Beet Supplement and Their Effect on Indicators of Anaerobic Capacity and Fatigue and Achievement of Running A 400m Freestyle Under 20 Years Old

Abstract

          The study aims to use exercises prepared by researchers based on codification on the target time to carry the training and according to the equation of the scientist Frank, where three distances are rationed according to the target time for running 400 m freestyle and they are (150 m, 300 m, 600 m) to develop indicators of anaerobic ability and fatigue to develop the achievement of a 400m freestyle sprint without 20 Year.          As well as the role of beet supplement in achieving the achievement of the effectiveness of 400m free, where nutrition plays an important role in raising the level of runners and performing their exercises to the fullest, and since the effectiveness of 400m is a tactical anaerobic activity where lactic acid accumulates in the muscles, hence the role of nutritional supplements in improving the runners' endurance and delivering more oxygen to the muscles during training as it is taken from natural food sources and a suitable environment for the work of the body's muscles as well as through the role of beetroot rich in nitrates, which is metabolized into nitric oxide, which in turn leads to the widening of blood vessels, which facilitates the blood flow increases endurance, improves energy and enhances the efficiency of oxygen transport, , as well as an excellent source of vitamin C and an antioxidant that supports immune health and respiratory health by producing nitric oxide, this is what researchers have proven, Where the researchers used the experimental method in the research with a design of three equivalent groups (control, first experimental, second experimental) with two pre and post tests for its suitability to the nature of the problem that it wants to solve, and the research community was chosen from the hostile activities of 400 m free in Iraq, who are (35) runners. Selecting a sample from the community in the simple way and their number reached (17) runners in the governorates of Kerbala and Baghdad, and (2) were excluded from the sample for equivalence procedures, and they were distributed into three groups in the same way (control group, first experimental, second experimental).          Where the first experimental research sample was applied exercises according to the target time according to the equation of the scientist Frank in addition to doses of beet supplement and the second experimental on exercises according to the target time according to the equation of the scientist Frank and the control sample was limited to training the trainer only, and the researchers concluded that there are differences in indicators anaerobic capacity, fatigue, and 400m free achievement for the benefit of the sample that took exercises according to the target time according to the equation of scientist Frank and beet supplement on the control sample that applied the trainings of the trainer, and the beet supplement had the preference of the first experimental group over the second experimental group that did not give the supplement.          The researchers concluded that training according to the target time according to the equation of the scientist frank, which was applied by the members of the second experimental group to develop indicators of anaerobic capacity and fatigue and achieve 400m freestyle is better than the group that applied trainer training.
