As the body ages, the bones become thinner. This can result in localized thinning with the hip bones, which is associated with a higher risk of a fracture.
For the study, researchers gathered 34 men over the age of 65 and had them hop for two minutes a day over a period of one year. The men were instructed to only hop on one leg so the other leg could be used for comparison.
Researchers discovered that bone mass increased by seven percent in parts of the exercised hipâs cortex. They also discovered an increase in the layer density of the spongy bone found underneath the cortex.
These effects were also present in the thinnest areas of the hip boneâthe parts of the hip that are most susceptible to fractures following a fall. The results could possibly help with preventing and managing osteoporosis, a disease responsible for more than 8.9 million fractures worldwide each year.
Study authors canât confirm if the same results would be seen in women since the participants were all men. Furthermore, the participants didnât have osteoporosis, so itâs still unclear if these hopping exercises would be safe for osteoporosis patients.
The studyâs senior author, Dr. Katherine Brooke-Wavell, still concludes that â…over time, our study shows that brief hopping or jumping exercises that target specific regions of the hip, could increase bone strength and reduce the chances of hip fracture.â
