Study type | Interventional |
This study evaluates the effect of vitamin D supplementation on outcomes of 10 weeks progressive strength training in 100 ageing subjects (>45 years of age). Participants will be recruited into two similarly sized strata; one containing COPD patients and one containing healthy subjects of similar age. In each stratum, half the participants will receive vitamin D supplementation and half the participants will receive placebo
