Extracts from this document...

Introduction

Physical preparation and fitness for the uniformed services The term lifestyle is a combination of attitudes, habits and behaviours that have a significant influence on the way a person lives and experiences their daily life. It is used in a variety of ways in the context of human development. It sometimes refers to the particular attitudes and habits that a person has, or to what is typical of a defined group of people. In this sense the lifestyles of 'healthy' people are seen to be distinctive and different form the lifestyles of 'unhealthy' people. 'Lifestyle' is also associated with the consumption or use of a whole variety of things that affect human health and development. These range from the foods you consume to the use of alcohol, drugs and cigarettes. In this sense, 'lifestyle' factors refer to both your attitudes and behaviours. There are several factors that can influence a persons lifestyle, either positively or negatively. The nutritional and dietary choices that a person makes can lead to a healthy or unhealthy lifestyle, a person needs to maintain adequate nutrition to meet their specific health and growth needs, food that contains a high level of fat, sugar or salt is likely to be of poor nutritional quality. Another factor that can influence a persons lifestyle is the amount of exercise they do. A person that takes more exercise is more likely to live a healthier lifestyle than a person that does not take regular exercise. Stress can also influence lifestyle, if a person is stress it may be down to factors within their lifestyle, such as excessive work roles/long hours, lack of sleep, health problems or financial commitments and problems.

An alternative for iron in vegans include * Dried fruit, green leafy vegetables and egg yolk(if not vegan) * Fresh orange juice with meals.(vitamin c) Studies have shown that vegetarians have low intakes of : ? IODINE (found in milk and seafood) ? VITAMIN B12( fortified cereals, tofu and yeast extract) ?

Conclusion

Physical fitness helps recruits meet those demands that the environment may place. Fitness tests not only show their strengths and weakness at a particular time but also show their potential so they can identify what they can do producing a marker to see if army life is the right one for them. For example if a recruit can do the 1.5 mile run well then their fitness can be developed and improved so that they are able to do 5 or six miles that may be required when on an operation. (www.army.mod.uk/) In terms of actual test the Army use the 1.5 mile run, press up test which is the amount of press you can do in two minutes, and the sit up test (as many in two minutes). In order to pass the twelve weeks of basic training they have to do the 1.5 mile run in under 10mins 30 sec for males for jobs and faster times for the infantry. The time is also different for females' people going into different areas of the Army. You also have to do a certain number for the other two tests. The press up tests is a good way of showing how well a person can lift their bodyweight and shows their upper body strength and endurance. This could be very important when on the assault causes the Army use because being able to lift your body is needed to get over obstacles. The test is also beneficial because when completing the assault courses you have to do it with Army with military equipment such as a helmet, rife and other kit where strength and endurance is needed.
