Exercise at any age is vital for healthy bones and is essential for the prevention and treatment of osteoporosis.
Exercise not only improves bone health, it also increases muscle strength, coordination and balance and helps improve overall health.
Why do you exercise?
Bones, like muscles, are living tissue that responds to exercise by becoming stronger. In general, women and young men who exercise regularly reach a higher bone density (the highest level of consistency and strength of bones) than those who do not exercise. Most people reach peak bone density between 20 and 30 years old. From that age usually bone density begins to decrease. Women and men over age 20 can help prevent bone loss hacienda exercise frequently. The exercise allows us to maintain muscle strength, coordination and balance, which in turn helps prevent falls and fractures. This is especially important for older adults and people who have been diagnosed with osteoporosis.
The best exercise to strengthen bones
The best exercise for your bones is required weight-bearing. This type of exercise makes you strive to work against gravity. Examples of these exercises include weight lifting, walking, hiking, jogging, stair climbing, tennis and dance. In contrast, exercises that do not require weight-bearing include swimming and cycling. While these exercises help strengthen and maintain strong muscles and reduce the risk of cardiovascular disease, are not the most effective in strengthening bones.
If you have health problems such as heart problems, high blood pressure, diabetes or obesity, or if you are 40 years old or more, consult your doctor before you start exercising regularly. According to the Surgeon General, the optimal goal is to exercise for at least 30 minutes most days; preferably daily.
Pay attention to your body. When starting an exercise routine, you may have some pain and discomfort in the muscles, but should not be painful or last more than 48 hours. If this occurs, you may be working too hard and need to slow down. Stop exercising if you feel any pain or discomfort in the chest and talk to your doctor before your next workout.
If you have osteoporosis, it is important to ask your doctor what activities are safe for you. If you have low bone density, experts recommend that the column is protected and avoiding exercises or activities that cause bending or twisting of the back. Moreover, should avoid high-impact exercise to reduce the risk of breaking a bone. You can also consult with an exercise specialist to teach you the proper progression of their activities, to stretch and strengthen muscles safely, and correct bad posture habits. An exercise specialist should have a degree in exercise physiology, physical education, physiotherapy or similar specialty. Be sure to ask if you are familiar with the special needs of people with osteoporosis.
A comprehensive system to combat osteoporosis
Remember, exercise is only part of a regimen for the prevention or treatment of osteoporosis. Like a diet rich in calcium and vitamin D, exercise helps strengthen bones at any age. But it is possible that good nutrition and exercise are not enough to stop the loss of bone density caused by medical conditions, menopause or certain habits such as the use of snuff and excessive consumption of alcohol. It is important to talk to your doctor about your bone health. Ask if you are a candidate for a bone density test. If densitometry shows low bone mass, ask what medications may help maintain healthy bones and fight osteoporosis.
A new brand of smartphones defy Samsung and Apple
We know that Samsung is the largest manufacturer in the world of smart phones, and Apple is number two. But, do you have any idea who is the third largest is?
¿Lenovo? ¿LG? Nokia nosing? ¿Sony? No, no, no and no. It is a Chinese company called Xiaomi.
If you´ve never heard of Xiaomi, you can soon do it.
Xiaomi raised 1,100 million dollars in funding from some of the most powerful players in the high tech industry. That gives the company a value of $ 45,000 million - larger than LG, Motorola and Sony together. Xiaomi is now the new world´s most valuable company, even more than Uber, Airbnb and Pinterest.
Xiaomi is also the smartphone maker´s fastest growing company. Its sales soared 211% to more than 17 million smartphones in the third quarter of 2014 - a little less than half the number of iPhones that Apple sold, according to IDC.
Xiaomi participation in the market more than doubled to just over 5%. A year ago, was only 2% of the market.
The smartphone maker in China rose so fast with that focused on China and some nearby high-growth countries. Xiaomi is now the number two brand smartphones in China (behind only Samsung), and recently began selling phones in Indonesia, Mexico, Russia, Thailand and Turkey.
Xiaomi arrived in growth markets by storm, offering super low price phones online sales only. The magnificent smartphone E4 company debuted in August, designed to be at home the iPhone killer. Its design almost exactly like the iPhone, helps.
The company has a unique business model: not even about making money with their phones $ 130, which sells at cost. Most of the proceeds from the sale of accessories and applications.
Xiaomi also has a knack for marketing, advertising campaigns have attracted a massive group of very loyal fans in China.
"We will strive to continually bring innovation to everyone, with a goal of producing high-quality, high-performance devices with great user experience," said Bin Lin, founder of Xiaomi, in a Facebook message Monday . "In January 2015, we will launch our next flagship device".
The big question for Xiaomi is whether it can grow beyond the countries where it already sells phones. For example, could Xiaomi shake the US smartphone market, which is dominated by Samsung and Apple?
Chinese manufacturers of smartphones have not exactly been welcome in the United States. None of the major national competitors Xiaomi -Lenovo, Yulong and Huawei- have made no progress in America.
For most of the past decade, Nokia was the world leader in sales of cell phones without a significant presence in the United States. LG, Sony and many others have found international success, but failed to gain traction on US soil.
Xiaomi has no plans to sell phones in the United States. But when that day comes, he will face his greatest challenge.

The cord blood: What You Should Know
The cord blood is present in the blood vessels of the placenta and umbilical cord, and is collected after the baby is born and then cut the umbilical cord; an important detail.
"Because cord blood is usually collected after delivery and after cutting the cord, intervention is generally safe for both mother and baby," says Dr. Keith Wonnacott, PhD, Branch Chief Therapies Office Phones Cell Therapies, Tissue and Genetic FDA.
The use of cord blood is only approved for interventions "hematopoietic stem cell transplantation," which was performed in patients with disorders of the hematopoietic (blood producing). The cord blood contains blood cell production can be used to treat patients with cancers of the blood such as leukemias and lymphomas, as well as certain blood disorders and immune system, such as stem cells of sickle cell anemia and Wiskott-Aldrich
"The cord blood is useful because it is a source of stem cells that are transformed into blood cells. Cord blood transplants can be used for people who need feedback, ie ´re-produce´ these cells producing blood cells, "says Dr. Wonnacott.
For example, in many cancer patients, the disease is found in the blood cells. Chemotherapy to treat these patients undergoing cancer cells eliminates both as producing healthy stem cells of blood cells. Transplantation of umbilical cord stem cells can support the regeneration of blood cells following chemotherapy.
However, the cord blood is not a cure-all.
"Given that cord blood contains stem cells, have been several cases of fraud related to cord blood," says Dr. Wonnacott. "Consumers think that stem cells can cure all diseases, but science has not shown this to be true.Patients should maintain skepticism if the cord blood is available for uses other than blood regeneration by stem "cells.
Information about the storage of cord blood
After obtaining the cord blood is frozen and can be stored safely for many years. "The method of freeze-called ´criopreservación´-is very important to maintain the integrity of the cells," says Dr. Wonnacott. "The cord blood will be stored with care."
Blood from the umbilical cord can be stored in a private bank, so it is available if the baby in the future-or relatives of first or second degree, they need it. The private cord banks typically charge for the collection and storage of blood.
Alternatively, blood can be donated to a public bank so that doctors can use to treat patients who need blood stem cell transplants.
The FDA regulates the cord blood in different ways, depending on its origin, processing level and intended use.
The stored cord blood for personal use, use in relatives of first or second degree, and that also meets other requirements of the FDA regulations, does not need the consent of this body before being used. Still, private cord banks must comply with other requirements of the FDA, including those that require them to register and enroll in the listings, be updated on the proper use of tissues standards, testing and analysis and detection of diseases infectious patients (except when the cord blood is going to be used by the original donor). These FDA requirements ensure the safety of these products to minimize the risk of contamination and transmission of infectious diseases.
The cord blood is stored to treat patients with unrelated donor is eligible to be considered a "drug" and a "biological product". The cord blood in this category must meet additional requirements and be authorized in accordance with a Biologics License Application, or be subjected to research new drug application before it can be used. The FDA requirements help ensure the safety and efficacy of the products in their intended uses.
Not all units of cord blood meeting the requirements necessary to be stored in a public bank, added Safa Karandish, MT, safety officer for the FDA Consumer. If this happens, part of the donated cord blood may be used for non-clinical research.
Tips for Consumers
If you are considering donating to bank cord blood, it is important to study the various options during pregnancy to have enough time to make a decision before the baby is born. If you want to donate to a public bank, ask if the hospital will give birth in a program storage of cord blood.
If you have questions about the risks and the procedures followed to obtain blood, or the donation process, ask your doctor.
The FDA also has a database which is available with information on banks registered cord blood.
All assertions that the cord blood is a miracle cure is not created; it is not. Some parents may consider using a private bank as an "insurance policy" against diseases that may arise in the future. But it is important to remember that currently the only approved use of cord blood is the treatment of hematologic (blood disorders).
Also good to know that, in some cases, the cord blood is stored may not be appropriate for the child who donated."For example, it is not possible to cure some diseases or genetic defects with cord blood containing the same disease or defect," says Karandish.
Parents of children from ethnic minorities should especially consider donating to a public bank, says Dr. Wonnacott, because the more donations make these groups receive more help minority patients who need a stem cell transplant. (Recipients must be "compatible" with donors so that doctors are more likely to find a good candidate among donors within the ethnic group of the receiver).
"As far as public banks is concerned, there is a clear need for cord blood," says Dr. Wonnacott. "And there is a need especially among minorities to have stem cell transplants. The cord blood is an excellent source of stem cells for transplantation. "
And these transplants can change the lives of patients.
