Chronic Effects of a Training Program Using a Nasal Inspiratory Restriction Device on Elite Cyclists

Area of Science:

• Exercise Physiology
• Sports Science
• Respiratory Training

Background:

• Ventilatory efficiency is crucial for endurance performance in athletes.
• Respiratory muscle training (RMT) is explored as a method to improve exercise capacity.
• Novel devices for RMT require validation in athletic populations.

Purpose of the Study:

• To compare the effects of a 9-week cycling training program combined with RMT using the FeelBreathe (FB) device versus cycling alone on ventilatory efficiency in elite cyclists.
• To evaluate the ergogenic potential of the FB device as an alternative tool for performance enhancement.

Main Methods:

• Eighteen elite cyclists were randomized into an FB group (cycling + RMT) or a Control group (cycling only).
• Training intervention lasted 9 weeks, with gas exchange measured during incremental cycloergometer tests before and after the intervention.
• Key performance indicators and ventilatory parameters were assessed.

Main Results:

• The FB group demonstrated significant improvements in peak power, VO2max, and the first ventilatory threshold (VT1) compared to the Control group.
• The FB group exhibited reduced minute ventilation (VE), breathing frequency (BF), carbon dioxide output (VCO2), and heart rate (HR) post-training.
• The FB group also showed increased inspiratory time (Tin), expiratory time (Tex), and end-tidal partial pressure of CO2 (PETCO2).

Conclusions:

• Respiratory muscle training with the FeelBreathe device is an effective ergogenic aid for elite cyclists.
• This method can be integrated into daily training routines for performance enhancement.
• The FB device presents a novel, easy-to-use alternative for improving cycling performance.
