A fresh look at sports PSM-systems

Area of Science:

• Sports Science
• Physiology
• Biomedical Engineering

Background:

• Assessing athlete readiness is crucial for performance optimization.
• Current methods like blood lactate and VO2 max have limitations.
• The Coefficient of Anaerobic Capacity (CANAC Q) offers a novel approach.

Purpose of the Study:

• To investigate correlations between Respiratory Rate (RR) and Heart Rate (HR) dynamics during maximal intermittent exercise.
• To evaluate the effectiveness of CANAC Q in assessing General Functional Athlete Readiness (GFAR).
• To explore CANAC Q as a potential replacement for traditional readiness assessment methods.

Main Methods:

• 16 healthy volunteers (10 male, 6 female, age 21±1.17) performed maximal intermittent exercise on a cycle ergometer.
• Continuous monitoring of RR and HR using Transthoracic Electrical Impedance Rheography (TEIRG) via the "RheoCardioMonitor" system.
• Calculation of CANAC Q to determine athletic potential and GFAR.

Main Results:

• A very high degree of correlation was observed between functional indicators (M, HRM, GFAR) and CANAC Q across all experimental series.
• The results confirm the high effectiveness of CANAC Q in assessing GFAR.
• CANAC Q, measured in "beats", demonstrated high accuracy through TEIRG.

Conclusions:

• CANAC Q is a highly effective and accurate metric for assessing general functional athlete readiness.
• CANAC Q shows promise as a non-invasive alternative to blood lactate and VO2 max measurements.
• Understanding RR and HR dynamics provides valuable insights into athlete physiological responses during maximal exertion.
