[8] Since respiration is under involuntary control, we hypothesize that ANS modulation by isometric exercise may effect the respiratory function especially the forced respiratory parameters such as inspiratory reserve volume (IRV), expiratory reserve volume (ERV), vital capacity (VC), forced expiratory volume (FEV), and peak expiratory flow rate (PEFR).
Effect of ongoing isometric handgrip exercise on the inspiratory and expiratory reserve volumes
The main change seen on PFT is an approximately 20% drop in FRC (that portion of a breath that can still be exhaled after normal resting exhalation), due to a decrease in both expiratory reserve volume (ERV) and residual volume (RV).

Many literature reports emphasize the fact that morbidly obese patients have reduced expiratory reserve volume (ERV) and reduced al functional residual capacity (FRC), as well as restrictive respiratory behavior in many cases.
