"This study compared the ventilatory responses and exercise tidal flow-volume (V-t) loops during exercise in order to analyze the influence of gender on breathing strategy in a fit aging population. Sixteen trained elderly men (63.0 +/- 2.9 years) and eight peer women (62.3 +/- 5.5 years) performed an incremental test on a cycle ergometer," scientists in Ronchin, France report. "At 90% maximal oxygen consumption (VO2max), the women presented a significantly higher expiratory flow limitation (EFL) than the men (38 +/- 10 vs 17 +/- 8% of V-t, respectively) (P < 0.01) and a lower value of expiratory reserve volume relative to forced vital capacity (FVC) compared with the...
