<p><p><strong>Abstract</strong></p><p><strong>Aim: </strong>The aim was to evaluate height measurements made with the single view metrology method and to investigate the influence of standing position and different phases of gait and running on vertical height.</p><p><strong>Method: </strong>Ten healthy men were recorded simultaneously by a 2D web camera and a 3D motion analysis system. They performed six trials, three standing and three during gait and running. The vertical height was measured with the single view metrology method and in Qualisys Track Manager. The results were compared for evaluation. The vertical height in the different postures was compared to the actual height.</p><p><strong>Results: </strong>The measurements made with the single view metrology method were significantly higher than the measurements made with Qualisys Track Manager (p<0.001). The vertical height in the two standing positions was significantly lower than the actual height (p<0.05). The vertical height in midstance was significantly lower than actual height in the walking trials (p<0.05). No significant difference was found between maximum vertical height and actual height during running (p>0.05).</p><p><strong>Conclusion: </strong>The single view metrology method measured vertical heights with a mean error of +2.30 cm. Posture influence vertical body height. Midstance in walking is the position where vertical height corresponds best with actual height, in running it is the non-support phase.</p><p> </p></p><p> </p>
