Introduction

Contemporary lifestyle In this assignment I am going to: Identify the role of exercise in reducing the physiological effects of the ageing process and last of all describe how physical activity may reduce the physiological effects of the ageing process. This assignment will be based on four psychological ageing processes: arthritis (osteoarthritis and rheumatoid), hormones, joints and metabolism. Age: physical activity and the ageing process, changes in physiological function with age. Exercise definition Exercise: Exercise is physical activity that is planned or structured. It involves repetitive bodily movement done to improve or maintain one or more of the components of physical fitness-cardio respiratory endurance (aerobic fitness), muscular strength, muscular endurance, flexibility, and body composition. For example football consists of having good stamina and you can't achieve this if you don't have good fitness and train hard which involves exercising. I got this information from notes. Exercise and the ageing process Exercise has a major effect of the physiological effects of the ageing process. Fifty years and older is currently classed as the ageing process. As you get older a number of complications can occur. Exercise may decrease the chance of developing some of these diseases. Here are a number of these complications: * Immune system is less effective. * Brain mass decreases * Artery walls become harder and less elastic * Energy requirements decrease. * Balance loss * Muscle strength decrease * Co-ordination decrease * Vision decrease * Hearing decrease * Skin is less resilient * Bones become brittle * increased chance of osteoporosis * Motabolism decrease * Activity levels decrease * Loss of hair * Depression can occur Exercise protects against heart disease and stroke. Other benefits may be a reduced risk of the development of non-insulin dependent diabetes mellitus and a reduced risk of cancer of the colon. It may also help in the control of blood pressure, improving circulation and may have a beneficial effect on blood fats. ...read more.

Too much of one component can be as much harm to the body as too little. Deficiency diseases occur when there is a lack of a specific nutrient, although some diet related disorders are a result of eating an excess. Carbohydrates are the body's primary source of energy, and are a large part of most people's diets. They are also building blocks for larger molecules. Carbohydrates can be obtained by eating cereals, wheat, bread, pasta and potatoes. Proteins are used in growth and repair and in rare cases as energy. The main sources of proteins are meats, eggs, lentils and beans. Fats help in shock absorption and warmth, their main function being long-term energy storage. Fats are found in oils, butter, peanuts, milk and processed foods. Vitamins are organic compounds required in small amounts by the body. They are essential in all food, with the exception of Vitamin D, which can be produced by our bodies when exposed to enough sunlight. Vitamins act as co~enzymes, and are a component of active chemicals (like Vitamin A in retinal). Vitamins are also needed for vitamin absorption. Minerals do quite the same as vitamins except they are inorganic. Water is essential to our bodies - it is an excellent transporting medium, solvent, and coolant. Lastly, dietary fiber is needed for proper functioning of the digestive tract. Vitamins Vitamin A Source: Dark green leafy vegetables, carrots, cabbage, kale, leeks, broccoli, parsley, watercress, turnip greens, fresh or dried apricots, red peppers, fish and dairy products Function: Helps fight infection, maintains respiratory tract, keeps glands, skin and gums healthy. Vitamin B1 (Thiamine) Source: Cereals, legumes, nuts, pork Function: Promotes proper nerve functioning, helps with digestion of carbohydrates Vitamin C (Ascorbic acid) Source: All citrus fruits, green vegetables, kale, leeks, turnip greens, broccoli, watercress, brussel sprouts, tomatoes and cabbage Function: Prevents gingivitis and gum-bleeding. Keeps blood vessels strong and helps in the healing of cuts and bruises Vitamin D Source: Fish, cod liver oil, butter, egg yolks and fortified milk Function: Needed in maintenance of teeth and bones. ...read more.

Conclusion

together, then they must consummate the marriage, this is because sex is the only way of being closer to your partner than marriage, so it can only be shared in marriage because this is an important joining of two people. Also the fact that sex is supposed to be something special between two people to show their love for each other, so if someone wants to show their love for someone, they should be married before they can take the next step. Also if two people have sex then they might lead each other into a false sense of contentment, if this happens then they might marry for the wrong reason which will probably end up in a divorce or something to similar effect which will just end up in emotional damage. Also it can lead to pregnancy's which cannot be carried through because neither one of the people has the stability to care for a child, this can often happen because no contraception is 100% reliable. Also sex before marriage can increase the risk of a person getting aids, because if neither person has sex before marriage then it cannot have been sexually transmitted, but if it is a stranger then you have no idea of their sexual history, so there is a much greater risk of catching aids through sex and there is a risk of other sexually transmitted diseases. I think sex before marriage is acceptable because marriage is only a document with legal rights. I personally think that sex before marriage is ok but only if it is for the right reasons, because if there is no love behind it then it means nothing to anyone. But if the two people truly love each other but do not want to get married then they should not be sinners for expressing their love. Nowadays you are getting people from different cultures getting married which years ago was simply not exceptable. For example sikh and christians. ?? ?? ?? ?? Jake Heath-Grey ...read more.
