Whetherthe diminution affected thereserve orthe complementalair is of course notshown'. [Conclusion] These results indicate that forward head posture could reduce vital capacity, possibly because of weakness or disharmony of the accessory respiratory muscles. The changes are discussed in terms of trunk muscle action. Control observations in which the second of a VC pair was performed in an unstressed posture allowed correction for the influence of rebreathing. A 2016 study found that vital capacity – the maximum amount of air one can exhale from the lung after a deep breath – was significantly lower in those with improper posture. 87, No. 4, International Journal of Industrial Ergonomics, Vol. Hutchinson(4) records that the vital capacity is less in the re-cumbentthanin the erect posture: he gives the following figures in his owncase: Standing260cubicinches, sitting 255, recumbentsupine 230, and prone 220, a difference of about 600c.c. Hurtado & Fray [1933] found slight de- creases in vital capacity in the supine position. In fact, the January, 2004 issue of the American Journal of Pain Management reported on the relationship of poor posture and chronic pain conditions including low back pain, neck related headaches, and stress-related illnesses. During full support of body weight by the arms, the VC was slightly increased due to a significant increase in the inspiratory extreme and no change in the expiratory extreme. Does Sitting Posture in Chronic Obstructive Pulmonary Disease Really Matter? The effects of posture on lung volumes, including functional residual capacity (FRC), were investigated in 20 normal subjects and in 10 male patients prior to, and a mean of 78 hours (range 61–94 hours) following, coronary artery surgery. [Subjects] Twenty-six subjects, divided into the two groups (normal and forward head posture groups), participated in this study. 3, American Review of Respiratory Disease, Vol. Vital capacity. Twenty normal subjects, twelve males and eight females, had determinations of total lung capacity in the three body positions, sitting, supine and prone. determination of the lung diffusing capacity and tissue volume, as well as of the distributions of ventilation and perfusion, in order to further characterize this effect of posture on pulmonary function. Effect of sitting posture on respiratory function while using a smartphone ... we measured forced vital capacity, forced expiratory volume in 1 second, ratio of forced expiratory volume in 1 second to forced vital capacity, and peak expiratory flow. Checking slow vital capacity changes in each posture, it was confirmed that the vital capacity (VC) was the highest at 15°. Accessory respiratory muscle activity was also lower in those with forward head posture. Changes at the inspiratory and expiratory volume extremes were recognized by having the subjects do two VC efforts: the first standing and the second in the posture in question while continuing to breathe on the spirometer. 5, Al-Azhar Assiut Medical Journal, Vol. 5, 23 September 2011 | Physiological Measurement, Vol. 87, No. Several studies have investigated vital capacity (VC) lying and standing (McMichael & McGibbon 1939; Blair & Hicham 1955) in young, fit, predominantly male subjects under 40 years, and have shown that VC falls between 0 and 6.5% when subjects go from standing to supine posture.

Vital capacity in normal healthy individuals decreases from sitting to supine position. 14, No. Spinal extension produced small increases in lung volume at both extremes with no significant change in VC, whereas spinal flexion did not influence the upper extreme but did increase lung volume at the lower extreme. 32, No. 137, No. It is shown to be affected by various factors including age, lifestyle, disease, and change in posture.
