Background:

Being active is associated with beneficial health effects for subjects with chronic lung diseases. The association of physical activity (PA) with lung function in lung-healthy populations has been rarely analysed. Therefore, our aim was to investigate the association of accelerometer-based PA with spirometric parameters, maximal inspiratory mouth pressure (PImax) and pulmonary gas exchange capacity related to alveolar volume (TLCO/VA) in lung-healthy adults from the KORA FF4 cohort.

Methods:

Data was available from 341 participants (45% males, mean age 57 years, 47% never-smokers) without chronic lung diseases and FEV1/FVC ≥0.7 who completed lung function testing and wore ActiGraph GT3X accelerometers on the hip for up to seven days. According to their mean minutes/day spent in moderate to vigorous PA (MVPA), subjects were classified into activity quartiles. Other analysed PA variables were the achievement of at least one 10-minute bout of MVPA, and meeting the WHO activity recommendation threshold of 150 minutes/week of MVPA spent in bouts of at least 10 minutes. Linear regression models adjusted for possible confounders were applied.

Results:

Associations of MVPA quartiles with FEV1, FVC and GLI z-scores of FEV1 and FVC were found. In regression analyses, FVC was 157 ml higher in subjects engaging on average > 48 minutes/day in MVPA (4th quartile) compared to those with < 20 minutes/day (1st quartile). FEV1 was 139 ml higher comparing these quartiles. No associations were found for TLCO/VA. Engaging in MVPA for at least one 10-minute bout length was associated with higher PImax. Achieving the WHO PA recommendations was not associated with any lung function parameter.

Conclusion:

Weak, but positive associations of PA with lung function suggest that engaging in PA might benefit lung function of adults without chronic lung diseases.
