Table 3 Association of physical activity with pulmonary gas exchange and inspiratory muscle strength

From: Association of physical activity with lung function in lung-healthy German adults: results from the KORA FF4 study

  Pulmonary gas exchange (TLCO/VA), 10−1 mmol/min/kPa/l Maximum inspiratory mouth pressure (PImax), kPa
β (95% CI) p-value β (95% CI) p-value
MVPA quartiles,
 1st – least active (reference)
 2nd 0.01 (−0.47, 0.49) 0.98 0.39 (−0.32, 1.10) 0.28
 3rd −0.30 (−0.80, 0.19) 0.23 0.23 (−0.48, 0.94) 0.53
 4th – most active 0.25 (−0.25, 0.75) 0.33 0.05 (−0.68, 0.78) 0.90
10-min bout of MVPA achieved,
 yes vs. no −0.03 (−0.39, 0.34) 0.88 0.57 (0.04, 1.10) 0.04
WHO threshold achieved,
 yes vs. no 0.36 (−0.13, 0.84) 0.15 0.00 (−0.71, 0.71) 1.00
  1. The models were adjusted for sex, age, height, weight, smoking status categorized as never, ex-, or current smokers, education level, and a doctor’s diagnosis of hay fever
  2. TLCO/VA transfer factor of the lung for carbon monoxide adjusted for hemoglobin and divided by alveolar volume, PI max maximum inspiratory mouth pressure, CI confidence interval, MVPA moderate to vigorous physical activity
