Relationship between perceived fatigability and NIRS parameters. The scatter plots (A, B) present the relationship between the perceived fatigability and oxygenated myoglobin/hemoglobin (Δ[HbO2]). The scatter plots (C, D) present the relationship between the perceived fatigability and total myoglobin/hemoglobin (Δ[Hbtot]). Please note that R represents the Pearson’s coefficient of correlation and p value depicts the level of significance
