Body Composition, Exercise Physiology and Energy Metabolism Core

Due to the COVID-19 Pandemic, CRS operational hours have changed:    The Body Composition and Exercise Laboratories will be open on Tuesdays, Wednesdays and Fridays from 9 am- 5 pm and  open on Monday and Thursdays from 1:30 pm- 5 pm.

The Clinical Research Services (CRS) has partnered with the Department of Radiology and Biomedical Imaging to form a consolidated research core on the Parnassus campus.

The combined Body Composition, Exercise Physiology and Energy Metabolism Core offers the following services:

  • Exercise testing – treadmill testing, cycle ergometry, 6-minute walk tests, gait-speed, and shuttle walk.
  • Muscle function testing for a wide variety of muscle groups can be performed using a computerized Biodex isokinetic muscle testing machine.
  • High resolution 3D optical whole body scanning that provides up to 400 anthropomorphic measures.
  • Advanced bioimpedance measures.
  • Body composition and bone mineral density scanning - the combined core will have a new Hologic Horizon/A DXA system. This DXA system includes many enhanced features such as measures of visceral adipose tissue, abdominal aortic calcifications, high resolution vertebral fracture assessment, and scan modes for infant and children’s bone and body composition.
  • DICOM compatible reports and database exports for import directly into Excel or advanced statistical software will now be supported.
  • *** Service NO longer provided: VO2 max  and RMR testing***

Services are offered at 400 Parnassus Ave, C Level, see directions
