Physiological assessment of bagpipers: A preliminary study of cardiopulmonary parameters

This study examined pulmonary function of pipers and cardiac adaptation to the playing of the Great Highland bagpipe. Pipers (n=13) of varying ages (3 1-65 years) and playing experiences (2-20+ years) were evaluated for vital capacity (VC), maximal voluntary ventilation (MVV), and forced vital capaci ty (FVC) using a RIKO AS-600 spirometer. Subjects were monitored by impedan ce cardiograph for heart rate (HR), stroke volume (SV), and cardiac output (CO) at rest and during 5 minutes of playing. An automatic blood pressure ( BP) monitor collected BP values over the same time period. Eleven weeks aft er initial cardiac data collection, the BP and cardiac measurements were re peated using the same protocols. Mean values for HR, SV, and CO were calcul ated for rest and each minute (1-5) of playing. A 2 (data session) by 6 (re st, min 1-5) repeated-measures ANOVA was performed. Analysis revealed a sig nificant overall time effect (p< 0.001) on HR. A-priori contrast comparing all playing times with rest showed significant differences at all time poin ts. Analysis of SV and CO failed to find significance. Heart rate values ca lculated for percent of maximum ranged from 68% to 89% of maximum overall w hile playing (session 1) and from 55% to 81% of maximum (session 2). Predic ted percent of maximum values for VC and MVV found 77% of players above the ir maximum predicted values.
