Unit 5 Fitness and medical problems Task 1 Fitness a) Talk to your partner. The purpose of your conversation is to find out who is fitter. What questions will you use to find out? b) Reading What does it mean to be physically fit? Physical fitness is defined as "a set of attributes that people have or achieve that relates to the ability to perform physical activity" (USDHHS, 1996). In other words, it is more than being able to run a long distance or lift a lot of weight at the gym. Being fit is not defined only by what kind of activity you do, how long you do it, or at what level of intensity. Overall fitness is made up of five main components: Body composition Cardiorespiratory endurance Flexibility Muscular strength Muscular endurance Match the components of fitness from above with their definitions: ……………………………..……………………………..is the ability of the body's circulatory and respiratory systems to supply fuel during sustained physical activity. To improve it, try activities that keep your heart rate elevated at a safe level for a sustained length of time such as walking, swimming, or bicycling. Start slowly with an activity you enjoy, and gradually work up to a more intense pace. ……………………………..……………………………..is the ability of the muscle to exert force during an activity. The key to making your muscles stronger is working them against resistance. If you want to gain muscle strength, try exercises such as lifting weights or rapidly taking the stairs. ……………………………..……………………………..is the ability of the muscle to continue to perform without fatigue. To improve it, try cardiorespiratory activities such as walking, jogging, bicycling, or dancing. ……………………………..……………………………..refers to the relative amount of muscle, fat, bone, and other vital parts of the body. A person's total body weight (what you see on the bathroom scale) may not change over time. But the bathroom scale does not assess how much of that body weight is fat and how much is lean mass (muscle, bone, tendons, and ligaments). ……………………………..……………………………..is the range of motion around a joint. In the joints it can help prevent injuries through all stages of life. If you want to improve this skill, try activities that lengthen the muscles such as swimming or a basic stretching program.

The benefits of exercise are far-reaching. Clinical and epidemiological studies have demonstrated that regular aerobic exercise reduces the risk of death due to heart disease and stroke, aids in reducing weight, helps prevent diabetes mellitus, strengthens bones, and enhances immune function. The psychological benefits are also broad, and most studies suggest a positive relationship between physical fitness and mental achievement. How much exercise is enough to improve general health, reduce the risk of heart disease, and increase longevity? It is clear that regular exercise, along with a generally healthy lifestyle, is beneficial. People who have sedentary lifestyles make up half the population of industrialized societies.

Furthermore, physical activity improves your self-i_ _ _ e, as well as the ability to sleep well, manage s_ _ _ _s and tension. Task 3 Illness and exercise Physical activity is good for our bodies in many ways. However, there are times when illness makes some type of exercise difficult or unwise. On the other hand, there are specific exercises that can be used to help with particular conditions. a) Read the recommendations for people with one specific condition – can you guess which one it is? Start gradually if you are not used to regular exercise. Make sure you have a snack or drink of water when you need it, as becoming dehydrated will make you feel worse. If at any point you feel pain in your chest, arms or neck, stop exercising and rest. You must be careful about the exercise you take, especially aerobic exercise. Overdoing it will put a strain on the damaged tissue and could bring on angina. b) Write down advice on exercising for people with another medical condition and let the others guess what condition you have in mind. c) Listening Exercise and asthma (https://www.youtube.com/watch?v=Oi_bJXG7MyE) Listen to an expert giving tips on exercising to people with asthma and take down the main points. - What does asthma cause? - What triggers asthma attacks? - What are common symptoms? - What kinds of exercise should asthmatics do?
