Effects of Isometric Exercises on Balance, Heart Rate, Pulse Ox and Blood Pressure
A study testing Isometric exercises and No exercise in people with Exercise, Isometric, run by Carrick Institute for Graduate Studies at 1 site in United States.
Trial summary
Determine the effects repeated isometric exercises have on balance, blood pressure, heart rate and pulse ox. Another outcome measure will be a mental speed test (how quickly a subject can process information and make decisions based upon that information). Read more about this study

About this study
Determine the effects repeated isometric exercises have on balance, blood pressure, heart rate and pulse ox. Another outcome measure will be a mental speed test (how quickly a subject can process information and make decisions based upon that information).
Read the detailed description
Subjects will complete a mental speed test and will undergo Computerized Dynamic Posturography (CDP) testing using the modified Clinical Testing of Sensory Integration in Balance (mCTSIB) protocol: the subjects will be required to stand on a hard or compliant surface (a 4" tall foam cushion of known mechanical properties) in a comfortable posture, feet shoulder width, with eyes open or closed, head straight and arms to the side and free to move, gazing forward, and breathing normally. Immediately prior to the CDP testing, subjects will have their heart rate, blood pressure and pulse Ox measured. These will constitute the baseline information.
Subjects will then be divided into two groups: the isometric exercise group (they will be instructed to perform specific isometric exercises three times a week, for the next 8 weeks) and the control group (no exercises will be prescribe to them).
The same testing procedure indicated above will be followed at the end of the 8 weeks. The mental speed test, CDP testing, heart rate, blood pressure and pulse Ox will constitute the follow-up information.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Isometric exercisesOther
subjects will perform specific isometric exercises for 10-20 minutes, three times a week throughout the enrollment period
No exerciseOther
Subjects will go on with their life without any specific isometric exercise regimen during the enrollment period
| Study group | Role | What they receive |
|---|---|---|
| Active Isometric exercise | Experimental | Subjects performing the isometric exercises intervention Receives: Other: Isometric exercises |
| No exercise | Active comparator | Subjects not performing the isometric exercises intervention Receives: Other: No exercise |
What is being measured
The primary outcome is the main question the study is designed to answer.
Changes in Heart Rate
Changes in heart rate at rest will be assessed between baseline (at enrollment) and after the treatment period. It will be used to investigate if isometric exercises affect it and how much.
Measured: Baseline and at 8 weeks
Secondary outcomes (3)
Changes in Stability Score
The Stability Score is calculated as percentage ratio of the actual sway and the theoretical limit of stability.
Changes in Stability Score will be assessed between baseline (at enrollment) and after the treatment period. It will be used to investigate if isometric exercises affect it and how much.
Measured: Baseline and at 8 weeks
Changes in Blood Pressure
Changes in Blood pressure (measured in standard conditions) will be assessed between baseline (at enrollment) and after the treatment period. It will be used to investigate if isometric exercises affect it and how much.
Measured: Baseline and at 8 weeks
Changes in Mental Speed
The subject will be presented a series of word/image pairs and/or simple mathematical equations or number sequences. If a pair matches, the subject has to click the "Correct" button, if the pair does not match, the "Incorrect" button . However, if the word "Opposite" appears at the top of the screen, the asnwer needs to be reversed. The subject has up to 5 minutes to complete the task.
The Accuracy of the answers expressed as percentage will be used as measure of mental speed. Changes in Accuracy will be assessed between baseline (at enrollment) and after the treatment period. It will be used to investigate if isometric exercises affect it and how much.
Measured: Baseline and at 8 weeks

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Determine the effects repeated isometric exercises have on balance, blood pressure, heart rate and pulse ox. Another outcome measure will be a mental speed test (how quickly a subject can process information and make decisions based upon that information).
Detailed description

Immediately prior to the CDP testing, subjects will have their heart rate, blood pressure and pulse Ox measured. These will constitute the baseline information.
Subjects will then be divided into two groups: the isometric exercise group (they will be instructed to perform specific isometric exercises three times a week, for the next 8 weeks) and the control group (no exercises will be prescribe to them).
The same testing procedure indicated above will be followed at the end of the 8 weeks. The mental speed test, CDP testing, heart rate, blood pressure and pulse Ox will constitute the follow-up information.
