简要总结
It has patented a restriction and filtering device ventilatory nasal flow FeelBreathe with the aim of increase nasal airflow resistance, therefore the objective was to examine the effects of FeelBreathe with lung ventilation and gas exchange during exercise.
详细描述
Background: Different devices are currently used to train inspiratory muscles, thus showing an increase in the physical performance. It is a control trial to investigate the effects of a new restriction and filtering device ventilatory nasal flow (FeelBreathe).
Methods: A total of 27 trained male caucasian subjects (age: 32.5 ± 7.23 years) were recruited from different sports clubs. Measurement of maximum static inspiratory pressure were taken before exercise testing and an incremental test in cycle ergometer to volitional fatigue for the determination of gas exchange data. Each subject performed three identical submaximal exercises at 50% of ventilatory thresholds under different breathing conditions: 1) oronasal breathing 2) nasal breathing and 3) nasal breathing with Feel Breathe, Restriction and Filtering Device Ventilatory Nasal Flow.
Discussion: Researchers try to find if the new device called FeelBreathe causes changes in the lung ventilation and gas exchange during exercise. If the results show altered breathing pattern and cardiometabolic variables, FeelBreathe could be used to training respiratory muscles.

时间窗: Subjects were assessed during 8 weeks
VE (l/min), Vtin (ml/kg), BF (bf/min), VCO2 (ml/min), VE/VO2 (ml), VE/VCO2 (ml), RER (VCO2/VO2), PETO2 (mmHg), PETCO2 (mmHg), tin (s/insp), tex (s/expir), Vtin (ml/min), Vtex (ml/min), SPO2 (%) and VO2 (ml/kg/min) were assessed throughout the exercise on a cycle ergometer (ERGO-Line GmbH + CoKG, mod. Jaeger ER-900. Germany) using three different conditions of breathing: oronasal, nasal and nasal breathing with FeelBreathe, with 10-sec sampling intervals using a open circuit spirometry (CPX Cardinal Health, 234 GmbH, Leibnizstrasse 7, D-97204 Hoechberg, Germany).
