BASIC INFORMATION -Vitamins are organic substances, that are essential nutrients required in minute amounts to perform specific functions that promote growth, reproduction and the maintenance of health and life.B vitamins are water soluable vitamins only found in components of the body that store water. This means that there is no long-term storage of these vitamins in the body and they need to be provided in the diet daily, therefore they are essential vitamins.Vitamin B unlocks the essential fuels, carbohydrates, fats and protiens, into conversion for muscular energy in the body. Vitamin B nutrients are essential in the energy metabolization process. When an individual exercises the B vitamins in muscle cells are used to convert the bodies fuels into energy. Thus after use of these B vitamins the body needs replenishing. It is important to remember that vitamins are not used as fuels and differ from the fuel the body uses in the following three ways.
| ENERGY RELEASE |
| -Thiamin |
| -Riboflavin |
| -Niacin |
| -Pantothenic Acid |
| -Biotin |
| AMINO ACID METABOLISM |
| -Pyridoxine |
| HAEMTOPOIESES |
| -Folic Acid |
| -Cyanocolbalamin |
RDA's are stated in milligrams per 1000 Kcalories (unless otherwise stated).
Vitamin and Exercise Relationship
Vitamins are not used as fuels for the body , but as fuel substrates. The vitamin relationship with exercise involves their role as coenzymes in the oxidative process of cells or in the production and protection of red blood cells. The vitamin and exercise relationship can be viewed from the view point of the nutritionist and the physiologist. Traditionally the nutritionists are interested in the effects of exercise on vitamin requirements. The physiologist would be interested in the effects of vitamin supplementation on exercise performance. The answer to the question, does vitamin supplementation affect exercise performance, is that there is no conclusive evidence that shows a direct relationship between the intake of certain vitamins and physical vigor. More than fifty years ago experiments were done on army soldiers, who were given megadoses of vitamin supplements, that support this statement. The study used 26 subjects with 4 main experimental series and conducted 256 experiments. The physiological and biochemical responses were measured from the subjects. The objective measurements taken showed that vitamin supplementation had no effect either on stroke output of the heart or on the heart rate before, during or after exercise. It was interesting to note that the heart size was found to be slightly reduced on the average after the heavy work as compared with the size in the previous test, but the change was also shown in the placebo group. From the results of the study, the proper question to ask is how does exercise affect vitamin requirements? If an individual exercises frequently he or she will most likely deplete some of the vitamin stores in the body, which will need to be replaced.
