Bone Health and Physical Activity in LSAH Participants (LSAHNEWSV13_2_1)
Research Area:
Skeletal physiology
Species Studied
Scientific Name: Homo sapiens Species: Human

Physical activity, primarily weight bearing exercise, is an important factor in the development and maintenance of bone health. Weight bearing exercise is defined as any physical activity in which someone supports their weight (e.g., running, walking) or moves weights using their muscles (e.g., weightlifting, resistance training). For this study, weight bearing exercise was represented by the specific physical activities of walking, running, and weightlifting. This study compared the amount of participation in these activities between the Longitudinal Study of Astronaut Health (LSAH) participants, a group of comparisons, and the U.S. general population.
