The Body's Response to Aerobic Versus Resistance Exercise

January 16, 2013 updated by: Wayne Campbell, Purdue University
The purpose of this study is to identify the body's response to aerobic vs. resistance exercise. Throughout this study, we will examine food intake, appetite, and physical and mental well-being before, during, and after aerobic and resistance exercise.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: 1
Other: Resistance Exercise
The subjects will complete 2 resistive exercise sessions on non-consecutive days that will be supervised by our laboratory staff. The following exercises will be performed using the Keiser Sports Health equipment in Ismail Health, Exercise, and Nutrition Center: seated row, double leg press, seated leg curl, chest press, and leg extension. The subjects will individually perform 3 sets of 8-10 repetitions at an exercise intensity of 70% of pre-determined maximal strength for these exercises. Each repetition will be performed in a slow (six to eight seconds) uniform fashion, giving equal time to the concentric (muscle shortening) and eccentric (muscle lengthening) portions. One minute of rest will be allowed between sets. The last repetition of the third set of each exercise will be done to voluntary fatigue or the performance of 12 repetitions.
Experimental: 2
Other: Aerobic Exercise
The subjects will complete 2 aerobic exercise sessions on non-consecutive days that will also be supervised by our laboratory staff. The subjects will perform 45 minutes of aerobic exercise on a stationary bike at an exercise intensity of 70% of their heart-rate reserve.
Experimental: 3
Other: Control (Non-exercise)
The subjects will also complete 2 non-exercise sessions on non-consecutive days that will also be supervised by our laboratory staff. These sessions will consist of incorporating diversionary tasks throughout a 45 minute period consisting of a variety of motor and psychological tasks (tests of hand steadiness, alertness, optical illusions, mental acuity, etc.)

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
