Two-Year Longitudinal Trajectory of Inspiratory and Expiratory Spirometric Parameters in a Professional Cyclist Cohort Under Ventilatory Strategy Training (VST): Descriptive Extension of a Published 48-Week Cohort

Key Points

• To characterize the ongoing trajectory of spirometric parameters in professional cyclists during 24 months of Ventilatory Strategy Training.
• Aggregated monthly spirometric measurements were collected over 24 months from a cohort of ten professional cyclists.
• Six spirometric parameters were assessed, focusing on both inspiratory and expiratory measures.
• Data points were analyzed descriptively, comparing changes from baseline to 48 weeks and 24 months.
• All five spirometric parameters demonstrated continuous improvement over 24 months, surpassing gains noted at 48 weeks.
• Inspiratory parameters increased by 22.0% to 31.6% and expiratory parameters by 12.2% to 12.4% over the full period.
• The FEV1/FEV6 ratio remained stable, indicating sustained optimal ventilatory function.
