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 exclusion criteria, the subject will be excluded from the study.

Differences in muscle mass (kg), fat mass (kg), and extra- and intracellular fluid (L) between COPD patients and healthy older adults using BIA.

Time frame: up to 8 week Exercise Intervention

Handgrip strength dynamometry by Handgrip Dynamometer

Difference and changes in handgrip strength pre and post exercise

Time frame: up to 8 week Exercise Intervention

6 minute walk test distance by 6 minute walk test

With 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.

Time frame: up to 8 week Exercise Intervention

Skeletal muscle strength of leg by Kin-Com

Difference in muscle strength of leg using kin-com machine between pre and post exercise intervention.

Time frame: up to 8 week Exercise Intervention

C-reactive protein by Blood Analysis

Differences and changes in the concentration of the inflammatory marker C-reactive protein

Time frame: up to 8 week Exercise Intervention

Attention and executive functions measured by Trail Making Test (TMT)

In 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.

Time frame: up to 8 week Exercise Intervention

Attention and executive functions measured by Stroop Color-Word Test (SCWT)

A 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.

Time frame: up to 8 week Exercise Intervention

Gut function as reported by "The Gastrointestinal Symptom Rating Scale"

Self-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.

Time frame: up to 8 week Exercise Intervention

Physical activity as reported by "Physical Activity Scale for the Elderly

Self-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.

Time frame: up to 8 week Exercise Intervention
