Correlation between Lung Function and Functional Movement in Healthy Adults.

It is difficult to determine whether lung function improves by simple abdominal strengthening exercises, and studies on the correlation of lung function and functional movement are insufficient. Therefore; we aimed to identify the correlation between lung function and functional movement. We recruited 204 healthy adults and measured their forced vital capacity; forced expiratory volume in 1 s, maximum voluntary ventilation, maximum expiratory pressure (MEP), and maximum inspiratory pressure (MIP). We also extracted data obtained during functional movements. Differences between lung function and functional movement by gender were determined using independent sample t-tests, while the relationship between lung function and functional movement variables were analyzed using Pearson's correlation coefficient. Significant gender-based differences between lung function and functional movement, a negative correlation between MIP and inline lunge, and a significantly positive correlation between MIP and trunk stability push-up occurred in males. In females, a positive correlation occurred between MEP and hurdle step, MIP and deep squat, and MIP and hurdle step. Aspects of lung function (MEP and MIP) showed correlations with functional movements. The results showed that lung function and functional movement were correlated, confirming that there is a relationship between lung function and functional movement in healthy adults.
