Design outcomes

Primary

Measure	Time frame
Maximum Strength (One-Repetition Maximum), indirect method, begin and end of each phase (before each intervention and after six weeks)	—

Secondary

Measure	Time frame
Body composition (BIA, waist-hip ratio), physical activity (activity tracker, e.g. step counter, PASE score), physical capacity (Six-Minute -Walk Test, hand dynamometry), dyspnea (mMRC), quality of life (CRQ, SF-36, CAT), vitals (pulse, oxyygen saturation, blood pressure), lung obstruction (FEV1), breathing sample (13CO2/12CO2 in exspired CO2) alle parameters at begin and end of each phase (before each intervention and after six weeks), additional testung after three weeks of maximum strength, body compostition, vitals, had dynamometry, breathing sample)	—
