About this trial

This is an interventional screening trial for Vitamin D Deficiency focused on measuring Muscle Metabolic Function, Vitamin D Status, 25(OH)D, Older Adults

Eligibility Criteria

65 Years - 75 Years (Older Adult)All SexesAccepts Healthy Volunteers

Inclusion Criteria:

  • 65-75 years of age

Exclusion Criteria:

  • Currently have or have a history of cardiovascular or pulmonary disease that would preclude the involvement in the performance of exercise.
  • Uncontrolled diabetes or hypertension.
  • History of neurological conditions related to spinal derangement, disk disease, peripheral neuropathies, tremor and rigidity
  • History of leg/hip trauma, inflammation, infection rhabdomyolysis, or leg surgery in the past 3 months
  • Have a diagnosis of osteoporosis (as determined by DXA)
  • Participated in a resistance or aerobic training program in the last 3 months
  • Engage in more than 1 hr/week of vigorous activity
  • Body mass index >29
  • On hormone replacement therapy

Arm Label

Low 25(OH)D

High 25(OH)D

Arm Description

We will recruit individuals with low 25(OH)D (<30ng/mL).

We will recruit individuals with higher 25(OH)D (at least 20ng/mL units higher then that of the "low 25(OH)D group).

Outcomes

Primary Outcome Measures

Muscle VO2 consumption
The objective is to examine the difference in gastrocnemius VO2 consumption in individuals that either have normal-high or low 25(OH)D and are undergoing 7-days of a treadmill training program.

Intervention Name(s)
7 continuous days of aerobic training
Intervention Description
For 7 consecutive days, subjects will perform up to 45 minutes of exercise consisting of treadmill walking at a progressive intensity of about 60-65% of their maximum heart rate. This heart rate range is estimated to be below 60% VO2 max.
Primary Outcome Measure Information:
