Understanding the skeletal effects of resistance exercise involves delineating the spatially heterogeneous response of bone to load distributions from different muscle contractions. Bone mineral density (BMD) analyses may obscure these patterns by av

Prolonged weightlessness is associated with declines in musculoskeletal, cardiovascular, and sensorimotor health. Consequently, in-flight countermeasures are required to preserve astronaut health. We developed and tested a novel exercise countermeasu

Osteoporosis International: With other metabolic bone diseases, 21(4), pp 543-559. doi: 10.1007/s00198-009-1059-y. Retrieved from: http://www.escholarship.org/uc/item/3t19n08k

The aging process is associated with loss of muscle mass and strength and decline in physical functioning. The term sarcopenia is primarily defined as low level of muscle mass resulting from age-related muscle loss, but its definition is often broade

Structural patterns of the proximal femur in relation to age and hip fracture risk in women

Publikováno v: Bone, vol 57, iss 1

Fractures of the proximal femur are the most devastating outcome of osteoporosis. It is generally understood that age-related changes in hip structure confer increased risk, but there have been few explicit comparisons of such changes in healthy subj

Proximal femoral density distribution and structure in relation to age and hip fracture risk in women

Hip fracture risk rises exponentially with age, but there is little knowledge about how fracture-related alterations in hip structure differ from those of aging. We employed computed tomography (CT) imaging to visualize the three-dimensional (3D) spa

Quantification of Changes in Skeletal Muscle Amino Acid Kinetics in Adult Humans in Response to Exercise via Positron-emission Tomography with L-[methyl-11C] methionine

Publikováno v: Journal of Molecular Imaging & Dynamics.

Dynamic positron emission tomography (PET) imaging of with L-[methyl- 11 C]methionine (11C-MET) was developed in the late 1990’s to non-invasively estimate skeletal muscle protein synthesis, but no studies have shown that the measurements respond t
