Nurse Managed Sequential Strength Training and Bicycle Training in Chronic Obstructive Pulmonary Disease (COPD)

December 17, 2013 updated by: Margaret K. Covey, University of Illinois at Chicago

Nurse Managed Sequential Resistance Then Aerobic Training in COPD

This is a 16 week exercise training program for people with severe to very severe chronic obstructive pulmonary disease (COPD). The purpose of this study is to find out if performing strength training prior to initiating exercise training on a stationary bicycle is associated with greater gains in functional status than bicycle training alone or concurrent bicycle and strength training together.

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.

Detailed Description

Volunteers are randomly assigned to one of three groups: 1). 8 weeks of resistance (strength) training followed by 8 weeks of bicycle exercise training, 2). 8 weeks of chair exercise followed by 8 weeks of resistance (strength) training and bicycle exercise training, or 3). 8 weeks of chair exercise followed by 8 weeks of bicycle exercise training. The length of the training is 16 weeks for all 3 groups. Volunteers train 3 days per week in our lab located in the Chicagoland area and are supervised by an exercise specialist.

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

Intervention / Treatment

Active Comparator: Aerobic training alone
8 weeks of gentle chair (sham) training followed by 8 weeks of interval aerobic training on a stationary bicycle
Behavioral: Aerobic training
Cycle ergometry training will be performed in the lab on a stationary cycle ergometer, calibrated with a 4 kg weight (Monark 828E, Varberg, Sweden). Initial work rate will be 50% of peak work rate (PWR) as tolerated and will be evaluated weekly with progressive increases targeted to achieve the highest work rate tolerated for 3-5 minutes{: wks 1-2 50% PWR, wks 3-4 60% PWR, wks 5-6 70% PWR, wks 7-8 80% PWR}. An interval training protocol will be used with subjects performing four work sets of five minutes duration separated by rest intervals of unloaded cycling lasting 2-4 minutes.
Experimental: Sequential Resistance then Aerobic Training
8 weeks of resistance training of the lower body followed by 8 weeks of interval aerobic training on a stationary bicycle
Behavioral: Aerobic training
Cycle ergometry training will be performed in the lab on a stationary cycle ergometer, calibrated with a 4 kg weight (Monark 828E, Varberg, Sweden). Initial work rate will be 50% of peak work rate (PWR) as tolerated and will be evaluated weekly with progressive increases targeted to achieve the highest work rate tolerated for 3-5 minutes{: wks 1-2 50% PWR, wks 3-4 60% PWR, wks 5-6 70% PWR, wks 7-8 80% PWR}. An interval training protocol will be used with subjects performing four work sets of five minutes duration separated by rest intervals of unloaded cycling lasting 2-4 minutes.
Behavioral: Resistance training
Supervised training will be performed on a cable exercise system (Body Solid, Forest Park, IL) using six exercises that involve concentric and eccentric muscle actions: leg press, knee flexion, knee extension, calf raise, hip adduction, hip abduction. Subjects will perform the lower extremity exercises under the direct supervision of an exercise specialist three times per week. Subjects will perform 2 sets of 8-10 repetitions at 70% of their maximum strength for 2 weeks, then will perform 2 sets of 8-10 repetitions at 80% of their maximal strength for 2 weeks, and for the next 4 weeks they will perform 3 sets of 8-10 repetitions at 80% of their maximal strength. Sets will be separated by at least a 2-3 minute rest period for multiple-joint exercises and at least 1-2 minutes for single-joint exercises. A moderate velocity of muscle contraction (~1-2 seconds for concentric and eccentric contraction) will be used.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
functional capacity for aerobic exercise and for common daily activities
Time Frame: baseline, 16 weeks
baseline, 16 weeks
functional reserve as measured by the reduction in breathlessness and fatigue
Time Frame: baseline, 16 weeks
baseline, 16 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
functional performance and functional capacity utilization as measured by the Functional Performance Inventory and the CHAMPS Physical Activity Scale for Older Adults
Time Frame: baseline, 16 weeks
baseline, 16 weeks
