PURPOSE : The purpose of this study was to investigate the correlation between craniovertebral angle (CVA) and cardiorespiratory function (VO2max and VCO2max) in young adults.
METHODS : For this study, the students of D college were questioned and 50 members of D college were participated in our research.. Side-view pictures of each subject were taken in standing positions, in order to assess forward head posture (FHP) by measuring the craniovertebral angle. The craniovertebral angle was measured as the angle between a horizontal line at C7 and a line from the tragus of the ear to the spinous process of C7. And VO2max and VCO2max were measured by Quark CPET (cosmed co, USA) while the subjects were performed the treadmill running task of a intensity to set with respiratory mask. Subjucts were Then Pearson’s correlation coefficient was calculated to estimate the relationship between craniovertebral and cardiorespiratory function (VO2max and VCO2max) using SPSS for window.
RESULTS : There was a significant positive correlation between craniovertebral angle and VO2max during treadmill unning task (r=0.528, p<0.05). And there was a significant positive correlation between craniovertebral angle and CO2max during treadmill running task (r=0.566, p<0.05).
CONCLUSION : Foreward head posture is related to cardiorespiratory function, and it has a negative correlation with cardiorespiratory function.
