Assessment of muscle oxygenation following eccentric exercise-induced muscle damage using near-infrared spectroscopy
Fig 4
Change in tissue saturation index (ΔTSI%) during Sprint 1 from baseline in the experimental (EXP) group.
Values are presented as means with 90% confidence intervals (CI). The shaded region represents the greater of either the typical error (TE) or the smallest worthwhile change (SWC), serving as a threshold for interpreting practical significance. Outcomes are classified as unclear when the 90% CI overlaps zero and the shaded region. Standardised effect sizes (±90% CI) are reported for time points where changes exceed this threshold.
