Relationship between mean horizontal speed and mean decreases in oxygen saturation during the run.

<p>To simplify the analysis, the slopes were grouped into two ranges: <20% and ≥20%. Abbreviation: SpO₂, oxygen saturation.</p

Relationship between ground slope and thoraco-abdominal coordination (PhA) during the run.

<p>The ground slope values were grouped into four classes, each associated with a mean PhA value. When the slope increased to over 30%, a significant increase in PhA was observed, representing a decrease in thoraco-abdominal coordination. The best interpolation of these points is represented by the quadratic curve PhA = 12.897–0.773slope + 0.301slope². Abbreviations: PhA, phase angle.</p

Relationship between the mean decrease in oxygen saturation and thoraco-abdominal coordination (PhA) during the run.

<p>The PhA values were grouped into four classes, each associated with the mean decrease in SpO₂ (SpO₂ at rest—mean SpO₂ during the race). Reductions in thoraco-abdominal coordination, indicated by an increase in PhA, were significantly related to decreases in SpO₂. Abbreviations: PhA, phase angle; Δ SpO₂, mean decrease in oxygen saturation.</p

Relationship between the delta VE/VT ratio and the mean decrease in oxygen saturation during the run.

<p>Reductions in SpO₂ (SpO₂ at rest—mean SpO₂ during the race) were grouped into four classes, each associated with the delta VE/VT (difference between VE/VT ratio during the run and at rest). Increases in the VE/VT ratio were related to greater levels of oxygen desaturation. Abbreviations: Δ SpO₂, mean decrease in oxygen saturation; VE/VT, ratio between ventilation and tidal volume.</p
