Kinesiology Research Group• Goals
– Interdisciplinary• Humanities• Behavioral and Social Sciences• Life Sciences
– Student Researchers
What other questions or outcome measures can be integrated with bone strength measurements to create an
interdisciplinary project?
My Question to the Group:
PERIPHERAL QUANTITATIVE COMPUTED TOMOGRAPHY
(PQCT)
Clinical Measures• DXA
– Dual Energy X-ray Absoptiometry– An areal density (not volumetric)– Correlated with bone strength
A DXA test measures your bone mineral density and compares it to that of an established norm or standard to give you a score.
Areal NOT Volumetric BMD
Clinical Measures
• Peripheral quantitative computed tomography
• Distribution of bone is very important
Volumetric BMDAND Bone Structure
4% 38%
Outcome Measures (Bone)
Other Measurements1. Muscle Density
1. a surrogate of intermuscular adiposity
2. Fat Density
3. Muscle to Fat Ratio
4. Marrow Density1. Bone Marrow Adipose Tissue
To Do
• Establish protocol– Research– Community outreach
• Optimize adjustments and subject position
• Develop and Organize Potential Studies– Compare athletes with different loading backgrounds
• IRB
