Does Obesity Influence Women Cardiorespiratory Fitness and Daily Physical Activities?

Many obese individuals experience difficulties in executing household activities. In this study, we investigate the cardiorespiratory fitness (CRF) of obese vs. non-obese women, and the impact of obesity on cardiorespiratory functioning during daily household activities.

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

Methods: On 48 sedentary female subjects will be assessed by cardiorespiratory exercise testing with evaluation of peak oxygen uptake (⩒O2), heart rate (HR) and maximal cycling power output. Next, cardiorespiratory functioning will be assessed during household activities such as ironing (A1), cleaning floor (A2), walking and climbing stairs (A3).

Study Type

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

36 years to 56 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

Description

Inclusion Criteria:

  • Body Mass Index (BMI = weight in kilograms/(height in meters) x (height in meters)) as: healthy obese (OB group (OB); BMI between 30 to 39.9 kg.m-2; n = 20), and healthy non obese (NO group (NO); BMI between 18.5 to 24.9 kg.m-2; n = 28).

Exclusion Criteria:

  • comorbidities (other than obesity) :

    1. history of systemic hypertension or antihypertensive medication, diabetes mellitus, cardiovascular or respiratory disease, systemic disease, smoking;
    2. any drugs;
    3. BMI >40 kg.m-2;
    4. having a regular physical activity.

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.
Active Comparator: NO
NON OBESE WOMEN GROUP ( same age and same physical activities ) cardiorespiratory exercise testing with evaluation of peak oxygen uptake, heart rate and maximal cycling power output. Cardiorespiratory functioning is assessed during household activities such as ironing,cleaning floor,walking and climbing stairs.
Diagnostic test: cardiorespiratory fitness and daily physical activities evaluations

The cardiopulmonary exercise testing is performed on a cycle ergometer connected to cardiovascular and respiratory software. Subjects have a facemask, which collected respiratory and metabolic variables.An incremental exercise test is performed up to exhaustion. ⩒O2 is recorded and heart rate is averaged by an electrocardiogram system.

Cardiopulmonary exercise testing during household activities Subjects have to perform 3 everyday life household activities: ironing,cleaning floor,walking and climbing stairs.A wearable ambulatory indirect metabolic system is used with Holter mode to record cardiorespiratory measures.Subjects have to breathe through the K4b2 facemask and turbine.

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
Measure Description
Time Frame
Comparison of relative peak oxygen consumption between obese and non-obese women , mesured with indirect calorimetry
Time Frame: 2 months
⩒O2 peak comparison between OB vs NO women. For each household activity, the intensity expressed by the ratio ⩒O2 activity/resting ⩒O2 or the ratio ⩒O2 activity /⩒O2 peak will be compared between NO and OB
2 months

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.
