The effects of short-term high-intensity exercise on single fiber contractile function in humans are unknown. Therefore, the purposes of this study were: (a) to access the acute effects of repeated high-intensity exercise on human single muscle fiber contractile function; and (b) to examine whether contractile function was affected by alterations in the(More)
We examined rates of first hospitalization for COPD, rates of 5-year mortality among patients hospitalized for COPD, and comparisons of mortality between COPD patients and a matched cohort free of COPD. We computed standardized rates of first COPD hospitalization. Using Cox regression, we compared 180- and 181-day to 5-year mortality among COPD patients(More)
