Interval Training, Inflammation and Immune Function

Aging Clinical Trial

Official title:
The Impact of High Intensity Interval Training on Inflammatory State and Immune Function in Elderly Individuals

Clinical Trial Summary

PURPOSE: The purpose of this study is to investigate whether High Intensity Interval Training (HIIT)can improve the health and wellbeing of pre-diabetic elderly adults. In particular, there is specific interest in describing the effects of an interval exercise program on inflammatory state and immune function.

DESIGN: Subjects will be sedentary, 65 to 80 years old adults, with prediabetes as defined by fasting plasma glucose (100 to 125 mg/dl). Before and after a 10-12 week High Intensity Interval Exercise training program subjects will undergo several tests including: 1) a maximal treadmill test, 2) an Oral Glucose Tolerance Test, 3) muscle biopsy, 4) body composition, 5) several physical function tests and 6) other health related measures including lung function, arterial stiffness and several blood measures (e.g. liver enzymes, kidney function).

DATA ANALYSES & SAFETY ISSUES: As there are no comparison groups, data analyses will consist of performing paired t-tests on pre and post exercise training values for each of the measurement variables of interest. In addition, the data will be used to provide power calculations for future grant proposals. High Intensity Interval Training is a very safe exercise modality. The regular use of vigorous intensity exercise intervals have been used extensively in exercise training. In fact, the exercise intervals will start at levels lower and will be of shorter duration than were used during the maximal exercise test. They will then be carefully and slowly made to be more challenging as each subject is able to safely tolerate.

HYPOTHESIS: The investigators hypothesize that HIIT will result in significant improvements in markers of inflammation, immune system markers and other health-related risk factors.
