XXXXXXXXXXASSESSMENT SAMPLE
Introduction
Vitamins are group of organic substances which are mainly present in the natural foodstuffs. Vitamins are important for normal metabolism. If people do not take proper vitamins then medical condition can result due to deficiency of vitamins. Moreover, vitamins have types like fat-soluble vitamins and water-soluble vitamins. Furthermore, this report will mainly focus on importance of vitamins for sports development, the composition of each vitamins for sports development, the biological functions of each throughout the lifespan, dietary sources for sports development, nutritional requirement, guidelines and therapeutic doses in Australia and factors contributing to states of excess and insufficiency and deficiency and sign and symptoms.
Composition of Vitamin:-
vitamin D is rapidly converted to 25D in the liver and activate in the kidney tubules to 1,25,2D, the hormone actively form, which are driven by parathyroid hormone (PTH) when blood calcium and/or phosphate concentrations fall below the normal range. Moreover, vitamin A is a chemically refers to retinol which derives from carotenoids and retinal, retinoic acid also composition of vitamin A. Vitamin C is an asco
ic acid which reduced form is dehydroasco
ic acid form. Asco
ic acid is a weak sugar acid related to glucose.
Importance of vitamins for sports development: -
Vitamins are play crucial role in sports development because it has crucial functions in all body systems like immune system, nervous system, hormonal system and so on. Vitamin A, C, E, D plays different role in the body.
Vitamin C plays pivotal role for connective tissue repair. So, vitamin C is very important for sports person because during training they have tissues injury then vitamin C helps to repair these damage tissues. Vitamin C is also essential for sports development because some oxidative may damage during different exercises so, it may help to reverse some oxidative. Moreover, vitamin C also helps to promote and keep healthy to immune system. In addition, Vitamin E is an antioxidant which may also help to prevent some damage oxidative and promotes immune system. It also helps to prevent muscle cramps. Vitamin E is an effective biological antioxidant which plays an important role to protect the cellular mem
anes from oxidative damage by free radicals. Moreso, it also helps to optimize the blood viscosity, especially as the rheology of an athlete which is related to performance. So, that is why it is very important for sports development. In addition, vitamin D plays an important role in physiologic functions so, that is why it is very important for athlete’s’ life. Sometimes, sports people get training indoor, do not take adequate Vitamin D and not get exposure in sunlight so, they have occu
ed deficiency of Vitamin D. According to several studies, sufficiency of Vitamin D is very essential for bone health because it prevents bone injury. Vitamin D is also helpful for immune system because it regulates innate immunity and inflammation. During training, most of the athletes have respiratory infection so Vitamin D influence susceptibility to such infections in athletes.
Biological functions:-
Vitamin D plays an important role in a variety of physiologic functions. Vitamin D is very helpful for health, training and performance. Vitamin D helps to make strong bones. So, that is why sufficient vitamin D status is important for bone health and prevention of bone injury in athletic populations. Moreover, it makes muscles strong and regulate the innate immunity of the sports people. Similarly, vitamin a helps to improve the eye vision which is helpful for atheletes.
Dietary Sources:-
Vitamin A: - Vitamin A is found in natural food and green vegetables like spinach, Ca
ot, Broccoli leaf, pumpkin, milk, butter, egg and so on. The bioavailability of carotene in food is variable because the process of metabolic convert carotene into retinol which varies from one person to another person.
Vitamin D:- Sun is the good source of vitamin D for athletes but there are variety of dietary sources where is available Vitamin D. Salmon, fatty fish, egg yolks, plus, fortified products also exist, such as, milk, cereal and orange juice are the natural food which have significant level of vitamin D. However, these dietary sources may appear significant, but it has approximately 50% the process of abso
ing dietary Vitamin D.
Vitamin C and E:-
Vitamin C and Vitamin E are the antioxidant which boost the immune system and fight with bacteria in the body. Vitamin E can find in natural food like green vegetables and vegetable oils and Citrus fruits like orange and green vegetables like
occoli, potatoes and so on are the good source of vitamin C. So, these vitamins are very essential for sports people because it can make healthy to sportsmen.
Specific nutritional requirements, guidelines and therapeutic doses in Australia: -
Vitamins are essential for athletes and requirements are same for adolescent athlete with non-active adolescent. Diet should be sufficient during training for athletes because it provides enough energy and nutrients. Moreover, nutritional supplements are essential during training and exercises so, it can find in pills, tablets, capsule and liquid forms. Athletes needs take 400 to 3,000mg of vitamin C per day for several days which can reduce the pain and speed up muscle strength recovery. In addition, sports people do not get sun exposure so, that is why they needs to take vitamin D supplement like >75 to 80nmol/L. According to Department of Health recommends that sports people needs to take 10 micrograms vitamin D supplements.
Factors contributing to states of excess:
After having vitamin, A, is stored in live and accumulates over time. Most people develop vitamin A toxicity when they have high-dose dietary supplements.
When people have excessive amount of vitamin D then it develops vitamin D toxicity. Vitamin D toxicity builds hyperglycaemia which can cause nausea, vomiting and weakness. Vitamin D can weaken the bones and damage the kidneys.
When sports people take excessive amount of vitamin C, sometimes, they complaint for dia
hoea because it has low toxicity.
Vitamin E has not adverse effects but high doses of alpha-tocopherol supplements can cause haemo
hage.
Factors to states of insufficiency and deficiency and Signs and symptoms: -
Vitamin A is helpful for body functions, but deficiency of Vitamin A is not common in developed countries. But some developing countries are taking enough Vitamin A. So, deficiency of Vitamin A develops skin problems, dry eyes, chest pain and so on.
Deficiency of Vitamin E develops muscle weakness, immune system problems, walking difficulties and so on. Vitamin C also develops many problems like skin problems and different nails shape and so on. People do not get sun exposure so, that is why sports people feel muscle weakness which leads to deficiency of Vitamin D. Vitamin D insufficiency is defined as serum levels of 20–30 ng/mL (50–75 nmol/L) and vitamin D deficiency as serum levels below 20 ng/mL . Factors which may inhibit the synthesis of vitamin D in athletes include geographic location, skin pigmentation, indoor training, early- or late-day training and extensive.
Conclusion:-
Vitamins are important for sports development because it makes strong and helps in body functions. Vitamins has lots of compositions and dietary sources, functions which are helpful for growth and development for athletes. Some risk factors which leads to different causes for development of sports and some signs and symptoms due to deficiency which can impact negatively on the body.
