effect of phonated breathing on oxygen uptake during and after submaximal cycling

Purpose: Positive expiratory pressure (PEP) exhalation during exercise is reported to improve body adaptation and enhance the tolerance in patients with chronic obstructive pulmonary disease. Wearing mouthguards results lower oxygen consumption increased performance by increasing PEP athletes. Airway resistance expiration can be manipulated phonation. Thus, aim of our study was examine effects phonated breathing on cardiopulmonary moderate subsequent recovery. Methods: 26 young healthy participants conducted same steady cycling protocol using three different patterns: spontaneous (BrP1), pronouncing sound “h” (BrP2) “sh” (BrP3). Heart rate, consumption, CO2 production, respiratory tidal volume, exchange ratio ventilatory equivalents were measured (Cosmed, Italy) before, 20 minutes after cycling. Data analyzed SPSS, significance level p<0.05. Results: The analysis revealed no significant differences related economy; rate increased, volume decreased compared both patterns exercise; effect BrPs parameters found Conclusion: Our do not confirm assumption that improves economy probably because low intensity applied. Further studies should at higher loads or dysfunction.
