Conditions

COPD, Covid19, OSA, Residual Symptoms of COVID 19

Brief summary

This study is being done to understand body's response to hybrid home-based and on-site rehabilitation program utilizing individually tailored exercises throughout a total of 18 sessions with 12 of them occurring onsite, in people with and without chronic respiratory diseases, such as Chronic Obstructive Pulmonary Disease (COPD) and Obstructive Sleep Apnea (OSA) and in individuals recovered from COVID-19. Exercise training programs vary widely for people with COPD, OSA, and during prolonged recovery from COVID infection. This study will help identify if this program is helpful to address muscle loss and fatigue specifically in populations with and without chronic respiratory diseases.

Inclusion criteria

* Ability to walk, sit down and stand up independently * Age 30 - 85 years * Ability to lay in supine or elevated position for up to 3 hours * Diagnosis of moderate to very severe chronic airflow limitation and compliant to the following criteria: FEV1 \< 70% of reference FEV1 -or- Obstructive Sleep Apnea (OSA) -or- 2 weeks post-recovered\* from laboratory confirmed case of COVID ● Willingness and ability to comply with the protocol \*Recovered is defined according to Brazos County Health District as someone who has been fever-free for 24 hours without fever-reducing medications, and it has been 10 days after onset of symptoms. Inclusion criteria control subjects * Healthy male or female according to the investigator's or appointed staff's judgment * Ability to walk, sit down and stand up independently * Age 30 - 85 years * Ability to lay in supine or elevated position for up to 3 hours * No diagnosis of chronic lung disease * Willingness and ability to comply with the protocol

Exclusion criteria

* Unable to exercise due to physical limitations (i.e. neuromuscular and/or orthopedic disorders) * Established diagnosis of malignancy * Presence of acute illness or metabolically unstable chronic illness * Presence of fever within the last 3 days. * Expected to have surgery within 1 month of screening or during exercise training * Any other condition according to the PI or research staff that was found during the screening visit, that would interfere with the study or safety of the patient. * Previous injury that could interfere with participation in resistance exercise protocol. * Failure to give informed consent or Investigator's uncertainty about the willingness or ability of the subject to comply with the protocol requirements. * (Possible) pregnancy. * Already enrolled in another clinical trial and that clinical trial interferes with participating in this study. When during the period from enrollment to the test day any condition causing the subject to not meet inclusion criteria or to meet

Primary

MeasureTime frameDescription
Whole-body protein and amino acid metabolism response to trainingup to 8 weeks Exercise InterventionWhole-body production rate measured after stable tracer administration

Secondary

MeasureTime frameDescription
Body Composition using Dual Energy X-Ray Absorptiometry Muscleup to 8 week Exercise InterventionMeasurement of muscle mass (kg)
Body Composition using Dual Energy X-Ray Absorptiometry Fatup to 8 week Exercise InterventionMeasurement of fat mass (kg)
Bone mineral density by BIAup to 8 week Exercise InterventionDifferences in muscle mass (kg), fat mass (kg), and extra- and intracellular fluid (L) between COPD patients and healthy older adults using BIA.
Handgrip strength dynamometry by Handgrip Dynamometerup to 8 week Exercise InterventionDifference and changes in handgrip strength pre and post exercise
6 minute walk test distance by 6 minute walk testup to 8 week Exercise InterventionWith this sub-maximal exercise test, aerobic capacity and endurance will be compared between COPD patients and healthy older adults. The outcome is the distance covered over a time of 6 minutes.
Skeletal muscle strength of leg by Kin-Comup to 8 week Exercise InterventionDifference in muscle strength of leg using kin-com machine between pre and post exercise intervention.
C-reactive protein by Blood Analysisup to 8 week Exercise InterventionDifferences and changes in the concentration of the inflammatory marker C-reactive protein
Attention and executive functions measured by Trail Making Test (TMT)up to 8 week Exercise InterventionIn Part A, the examinee is instructed to connect a set of 25 circles with numbers as quickly as possible while maintaining accuracy. In Part B, the examinee is instructed to connect a set of 25 circles, alternating between numbers and letters, as quickly as possible while maintaining accuracy. Measures attentional resources and is a measure of the frontal lobe executive functions of visual search, set-switching and mental flexibility. The total time in seconds will be recorded for each measure.
Attention and executive functions measured by Stroop Color-Word Test (SCWT)up to 8 week Exercise InterventionA word page with words printed in black ink, a color page with blocks printed in color, and a color-word page where the color and the word do not match. The examinee reads the words or names the ink colors as quickly as possible within a time limit. Measures selective attention and inhibitory control. The total time in seconds was reported for each trial.
Gut function as reported by The Gastrointestinal Symptom Rating Scaleup to 8 week Exercise InterventionSelf-administered questionnaire regarding gut function and associated symptoms. It is composed of 15 items (7-Point Likert Scale) assessing Reflux, Abdominal pain, Indigestion, Diarrhoea and Constipation. Scores range from 15 to 105 with a higher score indicating more discomfort.
Body Composition using Dual Energy X-Ray Absorptiometry bone densityup to 8 week Exercise InterventionMeasurement of bone mineral density (g/cm\^2)between COPD patients and healthy older adults using DXA
State of mood as measured by the Hospital Anxiety and Depression Scale (HADS)up to 8 week Exercise InterventionA fourteen item self-assessment scale. Seven of the items related to anxiety and seven relate to depression. Each item on the questionnaire is scored from 0-3 and this means that a person can score between 0 (no symptoms) and 21 (severe symptoms) for either anxiety or depression.
COPD Assessment Testup to 8 week Exercise InterventionSelf-administered questionnaire regarding impact of COPD on daily life
3-day diet diaryup to 8 week Exercise InterventionThe subject is asked to note in detail all the food and drinks consumed during 3 days (2 week days and 1 weekend day) in the week prior to each test day.
Group differences in learning and memory as measured by Digit Spanup to 8 week Exercise InterventionRecall of numbers in the same order (Digit Forward) and in reverse order (Digit Backward). Measures auditory attention and verbal working memory.
Group differences in overall cognitive abilities as measured by Montreal Cognitive Assessment (MoCA)up to 8 week Exercise InterventionAssesses several cognitive domains and is used for the screening of mild cognitive impairment. Total scores range from 0-30 with lower scores indicating decreased functioning.
Group differences in state of mood as measured by the Profile of Mood State (POMS)up to 8 week Exercise InterventionA psychological distress scale to measure mood disturbance in 6 domains - fatigue-inertia, vigor-activity, tension-anxiety, depression-dejection, anger-hostility, and confusion-bewilderment.
Group differences in learning and memory as measured by Controlled Oral Word Association Test (COWAT)up to 8 week Exercise InterventionThe examinee is required to say as many words as they can think of in one minute that begin with a given letter of the alphabet. The task contains three trials. Measures phonemic verbal fluency. The raw score (total and mean words recorded across the three trials) will be reported.
Functional Assessment of Chronic Illness Therapy - Fatigue (FACIT-F)up to 8 week Exercise InterventionQuality of life concerns related to fatigue will be assessed only in COPD patients with this questionnaire.
Peak Power and Strength by Keiser Resistance Training Equipmentup to 8 week Exercise InterventionChanges in Peak Power and Strength measured through testing completed using Keiser Pneumatic Resistance Training Devices
Physical activity as reported by Physical Activity Scale for the Elderlyup to 8 week Exercise InterventionSelf-administered questionnaire is intended for use in an elderly population and focuses on 3 types of activities: leisure time activities, household activities and work-related activities.
