Unit 3 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. (Adapted from http://www.seekwellness.com/fitness/) Task 2 Benefits of exercise a) Discuss. What benefits of exercise do you enjoy? b) Read the text. Explain the phrases in italics in your own words. 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? What precautions should they take? Task 4 Modals a) Match phrases with similar meaning: You don´t have to… He was able to… May I …? Shall we …? You mustn´t … You should … They had to… He managed to… Do you mind if I…? It isn´t necessary for you to… It is forbidden … You are supposed to… It was necessary for them to… Let´s … b) Modals expressing certainty certain - must possible – may/might unlikely – can´t E.g. It must be true. It may be true. It can´t be true. Complete the gaps with modal verbs must/ may/ might/ can´t: I´ll probably be going to the conference so I ………….. see you there. John is sweating and can hardly speak. He ……………. be very well. I´m sure it´s true. It simply …………… be true. Oh, you ………… be Mrs. Blunt. Nice to meet you. Jenny is on an assignment in Bali, she ………….. be in her office now. You can´t be serious. You …………… be joking. c) Past modals Rewrite the following sentences using may, may not, can´t and must + have without changing the meaning (there may be more possibilities): Example: I´m sure it was love. It ……….must have been love……….. . 1. One thing is for sure - they made a mistake. They…..................................................................................... 2. It is possible that they sold the house. They ….................................................................................... 3. I am not quite sure if she gave up her job.

Extra task: http://www.englishpedia.net/grammar-exercises/modals/modals-degrees-of-certainty.html Task 5 Injuries More than 10 million sports injuries occur each year. Most sports injuries are due to either traumatic injury or overuse of muscles or joints. 1. Wounds A wound is any break in the skin or body surface. Cuts can be caused by sharp edges such as jewellery or stones. When the skin is cut, the blood vessels at the wound edges are cut straight across, so blood loss is very likely. Grazes are wounds in which the top layers of skin are scraped off. Grazes are commonly caused by a sliding fall (trip on a running track) or friction burn (hands sliding along a rope). 2. Bone injuries A fracture is a break or crack in the bone. Bones can break when a direct impact is received (hockey stick striking the shin) or indirect force is produced by a twist or a wrench (a trip or stumble). 3. Joint/Muscle Injuries Sprain Injury to a ligament at, or near, a joint. It is often the result of a sudden or unexpected wrenching movement at the joint that pulls the bones within the joint too far apart and tears the tissues surrounding the joint. Strain Overstretching of the muscle, which may result in a partial tearing. Deep bruising (soft tissue injury) These injuries are usually accompanied by bleeding into the damaged area, which can lead to pain and swelling. Rupture Complete tearing of the muscle, which may occur in the fleshy part or in the tendon. 4. Heat Exhaustion Heat exhaustion, an advanced condition of hyperthermia, is very common in marathon runners; especially in hot, humid conditions. The body temperature rises, which makes blood rush to the skin to cool it down. This makes less blood available to the working muscles and so extreme tiredness, breathlessness and dizziness occurs. 5. Unconsciousness Unconsciousness occurs from an interruption of the brain’s activity. 6. Shock The circulatory system distributes blood round the body, so that oxygen and nutrients can be fed into the tissues. When the system fails, circulatory shock will develop. If not treated immediately, vital organs such as the brain may fail. A typical cause of shock is a blow to the chest (winding). Symptoms include: cold and pale skin, shaking or chills, chest pain, a weak but rapid pulse, shallow breathing, dizziness or general weakness, vomiting, unconsciousness. Task 6 Test your knowledge of injuries! Mark the following statements True (T) or False (F). 1. A wound where the top layers of skin are scraped off is called a rupture. 2. Both sprains and strains affect muscles. 3. Hypothermia occurs when the body is exposed to excessive heat. 4. A player who is winded and knocked to the ground could go into shock. 5. Shock occurs when blood pressure drops and the organs do not receive enough blood. T/F T/F T/F T/F T/F Task 7 Match the above injuries with suitable treatment: A) …………………………… a. Lay the casualty down on the back b. Raise the legs c. Loosen tight clothing d. Keep the casualty warm B) ……………………...

You should follow the DR ABC procedure: D Check for danger to both you and casualty. R Check for a response in the casualty. A Check the airway. Is it open and unobstructed? B Listen, look and feel to determine if the casualty is breathing. C Check circulation by feeling the pulse. Is the person bleeding? E) ………………………………… The casualty should be taken to a cool place and wrapped in cold, wet sheets. Cool water (nothing caffeinated or alcoholic) may be given slowly to the casualty. F) ……………………………….. Rest the injured part. Apply Ice to reduce the swelling for 10 minutes (max). Compress the injury, possibly using a bandage. Elevate the part to decrease the blood supply.
