Effect of Playing Position on Heart Rate and Blood Pressure in Brass and Wind Musicians.

Objective: The purpose of this study was to compare the impact of playing brass and wind instruments in seated versus standing positions on cardiovascular parameters in musicians. We hypothesized that heart rate (HR) and blood pressure (BP) would be higher while playing compared to resting, and would be higher in standing compared to seated positions.

Methods: Ten musicians completed two study visits. In both, resting, supine HR and BP were recorded, followed by 30 minutes of playing. In one visit, participants played seated, and in the other, played while standing. The order of these positions was randomized. BP and HR were recorded every 5 minutes during playing.

Results: Systolic BP was not affected by playing (p = 0.09, eta2 = 0.046) or position (p = 0.35, eta2 = 0.024). Diastolic BP increased while playing (p < 0.0001, eta2 = 0.32), but did not differ between positions (p = 0.21, eta2 = 0.03). Mean arterial pressure (MAP) increased while playing (p < 0.0001, eta2 = 0.25), but did not differ between positions (p = 0.68, eta2 = 0.03). There was a significant time X position interaction for HR (p = 0.0001, eta2 = 0.037). Simple main effects analysis revealed that HR was higher while playing in the standing compared to the seated position at all but one time point.

Conclusion: Playing brass and wind instruments increases diastolic BP and MAP, regardless of playing position, while playing in the standing position induces a higher HR compared to the seated position.
