Outcome Measures

Primary Outcomes (1)

  • Collection of imaging of BAT by magnetic resonance imaging from 10 participants in each of young and old study groups.

    Brown adipose tissue will be differentiated from white adipose tissue using fat fraction and T2\* relaxation time maps generated from a commercially available modified 6-point Dixon (mDixon) water-fat separation method. The participant may be removed from the magnet and repositioned during the exam in order to determine the same day variability of this method.

Study Arms (2)

Young group

20-40 years of age

Other: Maximal oxygen consumption (V02 max)Other: Brown adipose tissue (BAT) imagingOther: Muscle function testing

Old group

60-80 years of age

Other: Maximal oxygen consumption (V02 max)Other: Brown adipose tissue (BAT) imagingOther: Muscle function testing

Interventions

Aerobic fitness will be determined by measuring V02 max during a stationary bicycle exercise test.

Old groupYoung group

Brown adipose tissue will be differentiated from white adipose tissue using fat fraction and T2\* relaxation time maps generated from a commercially available modified 6-point Dixon (mDixon) water-fat separation method.

Old groupYoung group

This test will be done on a machine called a Biodex. We will measure the speed at which subjects move resistance at different percentages of their peak strength.

Sampling MethodNon-Probability Sample
Study Population

Males and females in the age ranges 20-40 and 60-80 years were recruited. Potential participants were medically screened to determine good health, weight stable (no gain/loss of ≥ 10 lbs in 6 months prior to screening), and without any contraindication to exercise. Approximately equal numbers of men and women will be recruited. Neither race nor ethnicity were exclusions.

You may qualify if:

  • Capable of providing informed consent and has voluntarily signed and dated an informed consent form, approved by an Institutional Review Board and provided Health Insurance Portability and Accountability Act authorization (HIPAA) or other privacy authorization prior to any participation in study.
  • Adult female or male, 20-40 or 60-80 years of age, inclusive at time of screening.
  • BMI ≥19.0 and ≤34.9 kg/m2, inclusive at time of screening.
  • Stable weight (No gain/loss of ≥ 10 lbs within 6 months prior to screening).
  • Non-smokers as defined by not smoked any tobacco or nicotine-containing products vape pens or vaporizers within 3 months prior to screening.

You may not qualify if:

  • History of type 1 or type 2 diabetes per self-report at screening visit 1; or Hgb A1c ≥ 6.5% at screening..
  • Actively pursuing weight loss and/or lifestyle changes at time of screening.
  • Weight \> 450 lbs at screening.
  • Uncontrolled hypertension (BP \>160 mmHg systolic or \>100 mmHg diastolic).
  • Mini Mental State Exam (MMSE) \<21, only applicable for those 60-80 years of age
  • Significant cardiovascular event (e.g. myocardial infarction, stroke) ≤ 6 months prior to screening visit; or stated history of congestive heart failure; or evidence of cardiovascular disease assessed during the ECG at screening.
  • Current infection (requiring prescription antimicrobial or antiviral medication, or hospitalization), or corticosteroid treatment (with the exception of inhaled or topical steroids) in the last 3 months prior to screening visit.
  • Prescription strength anti-inflammatory medication in the 6 weeks prior to screening.
  • Surgery requiring \>2 days of hospitalization in the last 3 weeks prior to screening visit.
  • Active malignancy or autoimmune disease.
  • History of chronic, contagious, infectious disease, such as active tuberculosis, Hepatitis B or C, or HIV, per self-report.
  • History of uncontrolled severe diarrhea, nausea or vomiting within 3 months of screening.
  • Uncontrolled severe (including stage III or above) gastrointestinal absorption-related disorders, within 3 months of screening, such as: obstruction of the gastrointestinal tract, inflammatory bowel disease, short bowel syndrome, gastroesophageal reflux disease, gastroparesis, peptic ulcer disease, celiac disease, intestinal dysmotility, diverticulitis, ischemic colitis.
  • History of drug or alcohol abuse (\> 3 drinks per day) within the last 5 years.
  • Pregnant, lactating or is within 6 weeks postpartum prior to the screening visit.
  • +8 more criteria
