Everyone knows that exercise is done regularly can improve health and help you feel good. But, did you know that exercise can help build strong bones?

What sports strengthen bones?

Sports that involve body weight or strength training is naturally beneficial for bone health. Exercises or activities that involve body burden include baseball, basketball, soccer, tennis, weight lifting, aerobics, dancing and walking. Although swimming is good exercise but not the activity that involves the body burden.

Sports that involve body weight has benefits in certain places. This means you only strengthen bones used directly. Therefore, a good idea to participate in various sports that involve body burden. To maintain the benefits of bone formation, exercise should be continued on a regular basis.

Why is exercise that involves the body burden of benefit to the bone?

Activities that involve the body burden of improving bone health in various ways. First, the sport that involves the body burden was found to stimulate bone formation. Second, exercise is to strengthen the muscles that pull and jerked the bone. These activities keep the bones strong. Third, physical activity increases strength, balance and coordination all of which can reduce the risk of falls and injury to the bone.

How to exercise when older?

Activities that involve body weight at any age still beneficial to bone. The study showed no association with increased physical activity of bone strength in children, adolescents, men and women, even the adults 90 years and older.

What if exercising too much?

Exercising too much lowering hormone that is needed for good bone health. If a woman exercising until the time when she stopped menstruating, she can increase the risk of bone disease, osteoporosis.

Is osteoporosis?

Osteoporosis is a bone disease that develops gradually and makes bones become brittle so that it can cause fractures.

Many women who suffer from osteoporosis. Almost one half of all women over 50 years of suffering a fracture caused by osteoporosis. Although osteoporosis affects more women, 5 million American men suffer from osteoporosis.

People often do not realize they have osteoporosis until a bone fracture as the disease develops slowly. Once broken bones, osteoporosis is often painful and disabling.

What can be done to prevent osteoporosis?

Nutrition (especially calcium), lifestyle (including exercise), and hormone (estrogen) are 3 major factors that affect bone health. Exercise and eating habits throughout life can affect the risk of developing this disease.

Is the only exercise can protect the bone?

Exercise that involves the body’s own weight is not enough to protect you from osteoporosis. Even if you do a sport that involves the body weight on a regular basis, but do not consume foods rich in calcium will weaken your bones.

Scientists agree that good nutrition can reduce the tendency of osteoporosis. Today many people do not consume adequate amounts of calcium. Fortunately, it’s never too late for the consumption of calcium.

> What foods contain calcium?

Foods that contain 75 percent calcium are milk, cheese and yogurt. Vitamin D helps the body to use calcium. Broccoli, salmon with bones is another source of calcium.

What about calcium supplements?

People who frequently consume less calcium intake of other nutrients essential for bone health such as vitamin D. Unlike supplements, foods also contain other nutrients needed to stay healthy bones. This is the underlying that calcium supplements may not help the lack of calcium when the food is low calcium intake.

Run a healthy diet with calcium would make bones strong. Remember that sports carry the load are also Useful for bone.

Benefits of Calcium Supplements

The results of recent studies have reported that supplements containing calcium and vitamin D provide little protection against broken bones (fractures) in women.

In a study of 36,000 middle-aged and elderly women, calcium supplements and vitamin D every day only slightly reduce the thinning of bones and reduce the risk of hip fracture (broken hip). However, the results are less promising as expected by the researchers.

After an average of 7 years, women who take supplements to obtain a value of 1% higher on tests of hip bone density compared with women taking placebo (without calcium).

Supplements reduce the risk of hip fracture by 12% but did not provide protection against a broken wrist and back. For women with more than 60 years of age who generally suffer from hip fractures, calcium supplements reduce the risk of hip fractures as much as 21%.

Besides the impact on bone health, calcium supplements found to increase risk of kidney stones. In a related study, the researchers found no association between calcium supplement with a reduced risk of colon cancer as had been predicted to researchers.

Findings of this study may raise questions because of an influx of calcium from food and other sources are not counted. This may affect the study results.

According to Todd Nippoldt, MD, an endocrinological at the Mayo Clinic, Rochester, Minn.., “Calcium continues to play an important role in bone health,” and it seems reasonable to recommend levels of calcium daily through diet, supplements or both.

Although calcium supplements alone can not provide enough protection against osteoporosis, calcium is still important as a healthy food for women.

“Under the general rule, we still recommend 1500 mg of calcium daily entries and 400 international units of vitamin D from foods and supplements,” said Dr.. Nippoldt. “However, these recommendations vary depending on individual circumstances.” You and your doctor can determine the input of calcium and vitamin D in specific conditions.
