Osteoporosis is a serious health issue that mainly affects postmenopausal women. Now, a Spanish study has confirmed that doing exercise during puberty can improve bone health in adulthood. In this scope, sports such as soccer, handball and basketball are better than others such as swimming. For years, osteoporosis has been referred to as the silent killer. It is characterized by a decrease in bone mass and an increase in the fragility of bones and the risk of fractures. It has been called the silent killer owing to its asymptomatic nature and the possibility of going undetected for many years.
