Near infrared spectroscopy (NIRS) variable responses between sets of leg extensor exercise. Maximum (Max) a) oxygenated hemoglobin (O2Hb), b) deoxygenated hemoglobin (HHb), c) total hemoglobin (tHb), d) O2Hb and HHb difference (HbDiff) and minimum (Min) e) O2Hb, f) HHb, g) tHb and h) HbDiff) are presented as mean values ± standard deviation for low (30% of 1RM) and high (80% of 1RM) load conditions for each set of leg extensor exercise. Relevant ANOVA p-values regarding set and load variables are presented within each panel. When a significant set*load interaction was found, post-hoc analysis with Bonferroni correction was employed for between load condition differences within each set. *, significantly different from 30% load condition (p < 0.0167)
