Abstract
|
|
|
PURPOSE : The purpose of this study was to investigate the effects of passive stretching exercises of the scalene muscles known as respiratory accessory muscles, on forced vital capacity.
METHODS : Ten of the participants were randomly selected as an experiment group to perform passive stretching exercises on the scalene muscles. Ten additional students were selected randomly as a control group. The forced vital capacity was assessed by using a digital spirometer (Pony FX, COSMED Inc, Italy) both before and after the passive stretching exercises were performed. Subsequently, passive stretching exercises of the scalene muscles were performed in the experimental group. There were no interventions to the control group.
RESULTS : As for the forced vital capacity (FVC), the experiment group showed significant increase in items of forced vital capacity (FVC), forced expiratory volume in 1 second (FEV₁), peak expiratory flow (PEF), forced expiratory volume in 1 second/vital capacity (FEV₁/VC), and maximal expiratory flow 75%(MEF 75%) after the scalene- muscles passive stretching exercises were performed. The control group, however, showed no change.
CONCLUSION : This study demonstrated that passive stretching exercises of the scalene muscles could be helpful for forced vital capacity improvement.
