Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This is a pilot study to develop a collaborative, translational research project investigating whether physical activity may in part exert a positive influence on aging via the mobilization of stem cells. Preliminary data will be collected to explore the relationship between physical activity and stem cell populations found in the blood. The study hypothesis is that stem cell decrease with age, but that persons who are more physically active will have a higher number of stem cells in the blood. The first assessment will include an evaluation of health, physical activity and lifestyle via questionnaires. Height, weight and abdominal girth will be measured, and blood will be drawn for immune and stem cell assessment. Participants will be given a pedometer and accelerometer to wear daily for 7 days. Participants will return for a second visit at which the pedometer and accelerometer will be returned and blood will be drawn. Stem cell and immune assays will be repeated to evaluate the variability of these measures over time. The correlation between stem cell numbers and physical activity will be analyzed.
