ExerciseThe word exercise can mean the following: *A setting in action or practicing. *Any activity designed to develop or hone a skill or ability. *Physical exercise ==Physical exercise== Physical exercise is activity performed in order to develop or maintain physical fitness and overall Health. Frequent and regular exercise is an important component in the prevention of some of the diseases of affluence such as cancer, heart disease, diabetes and obesity. Exercises are generally grouped into three types depending on the overall effect they have on the human body: * Flexibility exercises such as stretching improve the range of motion of muscles and joints. * Aerobic exercises such as walking and running focus on increasing cardiovascular endurance. * Anaerobic exercises such as weightlifting increase short-term muscle strength. Exercise can be an important part of physical therapy, weight loss or sports performance. Proper nutrition is as important to health as exercise. When exercising it becomes even more important to have good diet to ensure the body has the correct ratio of macronutrients whilst providing ample micronutrients, this is to aid the body with the recovery process following strenuous exercise. "Exercise bulimia" is a disorder in which too many calories purged from the body through exercising. It should be noted that Delayed onset muscle soreness can occur after any kind of exercise, particularly if the body is in an unconditioned state relative to that exercise. ==Exercise benefits== Frequent and regular exercise has been shown to help prevent or to improve major illnesses such as high blood pressure, obesity, heart disease, diabetes, insomnia, cancer [http://www.wcrf.org/] and clinical depression, among others. ==Common myths== Many common myths have arisen surrounding exercise, some of which have a basis in reality, and some which are completely false. * Spot reduction. It is a common belief that training a particular body part will preferentially shed the fat on that part; for example, that doing sit-ups is the most direct way to reduce subcutaneous belly fat. This is false. Most of the energy derived from fat gets to the muscle through the bloodstream and reduces stored fat in the entire body. Fat is reduced in a pattern determined mostly by genetics. Sit-ups may improve the size and shape of core muscles and may reduce the unsightly appearance of belly fat, but the belly fat will often be the last fat removed from the body. * Only overweight people need a physical before beginning an exercise program. Absolutely false. Only a physician can determine your ability to engage in an exercise program. Apparently healthy people can still have unknown medical conditions, such as a heart murmur, that can cause severe injury or death not only to themselves, but also to others that are dependent upon them, such as someone they are spotting. * Muscle tissue will turn into fat once a person stops exercising. False. Fat tissue and muscle tissue are fundamentally different. ==Too much exercise== Doing too much exercise can sometimes be harmful. The body needs time to rest, which is why most health officials say one should exercise every other day or 3 times a week. Without proper rest the chance of strokes or other Circulatory system problems is increased, and muscle will develop slower. Over-exercising does more harm than good. Performance is lost over-exercising, although the levels required to reach this are phenomenal (many hours every day of the week). For many activities, especially running, there are also significant injuries that occur with poorly regimented exercise schedules. ==List of activities used as physical exercises== *aerobics *calisthenics *cycling *dancing *martial arts *pilates *rowing *running *sexercises *sport *stretching *swimming *walking *warming up *weight training *yoga ==List of classes of physical exercise== *Aerobic exercise *Anaerobic exercise *Endurance *High-density exercise *High-intensity interval training (HIIT) *Resistance training Some activities can fall into more than one class of exercise. For instance: cycling can be used for endurance or high-intensity interval training; weightlifting is resistance training and can be high-density exercise with certain workout designs. ==Breathing== Active exhalation during physical exercise helps the body to increase its maximum lung capacity, and oxygen uptake. This results in greater cardiac efficiency, since the heart has to do less work to oxygenate the muscles, and there is also increased muscular efficiency through greater blood flow. Consciously breathing deeply during aerobic exercise helps this development of the heart lung efficiency. During breathing, males mostly use the intercostal muscles in the rib cage, females mostly use abdominal muscles. In strenuous exercise, it is likely that these differences diminish. ==See also== * Cross training * Heart rate monitor ==External links== *[http://www.ericdigests.org/pre-9219/exercise.htm Exercise Adherence] *[http://www.ericdigests.org/1998-2/exercise.htm Promoting Physical Activity and Exercise among Children] *[http://www.VirtuaTrainer.com Exercise Blogs] are becoming more and more common both to learn new exercises from others as well as to gain semi-anonymous peer-pressure to help one stay on track.

User:Szczels 13:03, 6 Mar 2005 (UTC) What does "muscle-sparing" mean? It's neither linked or explained in the text. ==Carbohydrates and muscle mass== Exercise uses up a muscle cell's glycogen reserves. Carbohydrates allow muscle cells to refuel. Without enough carbohydrates in your diet, you will lose muscle mass from exercising. According to [http://www.brianmac.demon.co.uk/articles/scni18a3.htm this essay], it is ideal to exercise 1.5 to 2 hours after a meal, and to have a meal sometime after exercise to refuel your muscle cells. User:Chira 19:22, 3 Mar 2005 (UTC) ==No Pain, No Gain?== is this part really necessary? i know when i train it hurts, i know it doesnt hurt as in injury - but its pain nevertheless, i personally think the statement is too subjective and doesnt fit within the article. : :I agree, lactic acid creates a "burning" effect and just lifting a heavy weight creates a feeling that could be described as pain. "No pain, no gain" could also be thought of just referring to the exhaustion that one feels after exercise. --User:Slux 16:58, 7 Apr 2005 (UTC) : :I removed that section, i moved the part about DOMS to the intro section. feel free to voice opinions. --User:weightshead Exercisebiologically based therapies Health See other meanings of words starting from letter: EEA | EB | EC | ED | EF | EG | EH | EI | EJ | EK | EL | EM | EN | EO | EP | ER | ES | ET | EU | EW | EX | EY | EZ |Words begining with Exercise: Exercise Exercise Exercise Exercise-induced_anaphylaxis Exercise/Physical_Fitness Exercises_in_style Exercise_ball Exercise_bicycle Exercise_bike Exercise_bulimia Exercise_equipment Exercise_instructors Exercise_intensity Exercise_intolerance Exercise_physiology Exercise_physiology Exercise_REFORGER Exercise_Tiger Exercise_trail Exercise_Zapad Exercise_Zapad |
