- Other: ExerciseOther: Non Exercise
- Registration Number
- NCT05156918
- Lead Sponsor
- Loma Linda University
- Brief Summary
The purpose of this graduate student research study is to determine if a high-intensity exercise program can slow or reverse biological (transcriptomic) aging and shed light on the underlying transcriptomic pathways involved.
- Detailed Description
24 males and 24 females will be randomly assigned to either the control group or the exercise group. Baseline measures will be obtained, including questionnaires (on stress, sleep, depression, activity level, and fitness), body composition measures, vital signs, and a blood draw. Control group participants will make no modifications to regular diet or exercise habits for 30 days. Exercise group participants will perform supervised high intensity exercise three times per week at the LLU department of physical therapy laboratory utilizing treadmills, stationary bicycles, and rowing machines. Results will be collected following conclusion of the 30-day study protocol.

Group Intervention Description Exercise Group Exercise Exercise group participants will perform supervised high intensity exercise three times per week at the LLU department of physical therapy laboratory utilizing treadmills, stationary bicycles, and rowing machines. Control Group Non Exercise Control group participants will make no modifications to regular diet or exercise habits for 30 days.
- Primary Outcome Measures
Name Time Method venipuncture procedure Change between baseline and 30 days Participants will have 8ml of blood drawn on two separate occasions by a certified phlebotomist. The first 8 ml (1.62tsp) blood draw will occur at 8am on day 1 of the study protocol. The second 8ml (1.62tsp) blood draw will occur approximately 30 days later. The total blood draw volume will be 16ml or approximately 3.25 teaspoons. The blood draw is to test for the effects of exercise on gene expression and aging.
- Secondary Outcome Measures
Name Time Method Perceived stress scale survey Change between baseline and 30 days The most widely used psychological instrument for measuring the perception of stress. It is a measure of the degree to which situations in one's life are regarded as stressful during the past 30 days. Responses are scored from 0 to 4. And the total score can be from 0 to 40.
"Scores ranging from 0-13 would be considered low stress. Scores ranging from 14-26 would be considered moderate stress. Scores ranging from 27-40 would be considered high perceived stress."Pittsburgh Sleep Quality Index Change between baseline and 30 days A self-rated questionnaire which assesses sleep quality over a 1-month period. Questions are scored between a zero and three. A total score of 5 or greater means poor sleep quality.
