Impact of Physical Activity on Women's Hip and Spine's Bone Density

Overview

Objectives/Goals My objective is to stress the importance of exercise to women's bone health. Methods/Materials I have used a bone density machine called DEXA to measure the bone density of fifteen physically active women and fifteen sedentary women. I recorded the results and then compared them. Results The average hipbone density for the sedentary women was 1.182 g/cm2 and the average hipbone density for the physically active women was 1.265 g/cm2. The average spine bone density for the sedentary women was 0.988 g/cm2 and the average spine bone density for the physically active women was 1.104 g/cm2. Conclusions/Discussion My study showed that physically active women have greater bone density than sedentary women especially in the women over 35 years of age. In my project, I also gathered the data on amount of milk intake and sunlight exposure from each of the subjects. After studying the data, I have concluded milk and sunlight exposure are important for healthy bones, but I did not see significant impact on the bone density. If I were to perform this experiment again, I would try to include more people in the study particularly under the age of 35. This is because I would like to figure out if physical activity really impacts people under the age of 35. Also, I would try comparing different contributing factors in more detail.
