Part of the confusion about the effect of exercise on cholesterol stems from the fact that most early cholesterol studies focused on both exercise and dietary changes, making it hard to tease out which of these factors was actually making the difference. Exercise can also help the body stay flexible, meaning that your muscles and joints stretch and bend easily. Martial arts like karate, ballet, gymnastics , and yoga are good choices. Can you tell me where it is, please? Some activities, like dance or martial arts, require great flexibility.
The Exercise-Cholesterol Link
When you give your heart and lungs this kind of workout regularly, they get stronger and are better at getting oxygen in the form of oxygen-carrying blood cells to all parts of your body.
If you play team sports, you're probably getting at least 60 minutes or more of moderate to vigorous activity on practice days. Some team sports that give you a great aerobic workout are basketball , soccer , lacrosse , hockey, and rowing.
But if you don't play team sports, don't worry — there are plenty of ways to get aerobic exercise. These include biking , running , swimming , dancing, in-line skating, tennis , cross-country skiing, hiking, and walking quickly. The heart isn't the only muscle to benefit from regular exercise.
The other muscles in your body enjoy exercise too. When you use your muscles, they become stronger. Strong muscles are also a plus because they support your joints and help prevent injuries. Muscle also use more energy than fat does, so building your muscles will help you burn more calories and maintain a healthy weight. You don't have to lift weights to make your muscles and bones stronger. Different types of exercise strengthen different muscle groups, for example:.
Strengthening the heart and other muscles isn't the only important goal of exercise. Exercise can also help the body stay flexible, meaning that your muscles and joints stretch and bend easily. Being flexible may also help improve a person's sports performance. Some activities, like dance or martial arts, require great flexibility.
But increased flexibility also can help people perform better at other sports, such as soccer or lacrosse. Sports and activities that encourage flexibility are easy to find.
Martial arts like karate, ballet, gymnastics , and yoga are good choices. Stretching after your workout will also help you improve your flexibility. One of the biggest reasons people drop an exercise program is lack of interest: If what you're doing isn't fun, it's hard to keep it up.
The good news is there are tons of different sports and activities to try to see which one inspires you. When picking the right type of exercise, it can help to consider your workout personality. The real danger lies in staying on the fast for prolonged periods, anywhere from three days to a month. When you dramatically reduce your calorie intake, you will lose weight.
But it can also cause all kinds of health problems, including muscle loss. Further, when you start fasting, your body goes into conservation mode, burning calories more slowly.
Keep in mind that the initial weight lost on a fast is primarily fluid or "water weight," not fat. And when you go back to eating, any lost weight usually gets a return ticket back.
Not only do most people regain weight lost on a fast, they tend to add a few extra pounds because a slower metabolism makes it easier to gain weight. Worse, the weight that is regained is likely to be all fat -- lost muscle has to be added back at the gym.
Side effects of fasting include dizziness , headaches , low blood sugar , muscle aches, weakness , and fatigue. Prolonged fasting can lead to anemia , a weakened immune system, liver and kidney problems, and irregular heartbeat. Fasting can also result in vitamin and mineral deficiencies, muscle breakdown, and diarrhea. When you drink laxative concoctions during a fast, there is an increased risk of fluid imbalance and dehydration.
The risks get more complicated and severe the longer you stay on a fast, or if you repeatedly go on fasts. It sounds logical that fasting could cleanse your body of harmful substances that could cause a host of ailments like obesity , fatigue , and headaches. But there is no scientific evidence that you need to fast to "cleanse" your body or remove toxins.
Your body - specifically, the kidneys , liver , lungs , colon , and skin -- is perfectly capable of removing toxins itself. Nutrition experts agree that fasting is a potentially dangerous, and not particularly effective, way to lose weight.
