Objective This study examined the contributions of fat mass (FM) and fat-free mass (FFM) to the magnitude of exercise pressor responses in humans. Methods The cumulative blood pressure responses (blood pressure index; BPI) to handgrip exercise (BPI hg ), post-exercise-circulatory-occlusion (BPI peco ), and cold-pressor activation (BPI cpt ) were collected from 67 individuals grouped by BMI (27.8 ± 7.3 kg/m 2 ), FFM index (FFMi, 29.1 ± 3.8 kg/m 2 ), and FM index (FMi 12.5 ± 4.8 kg/m 2 ) quartiles. BPI responses to HG were also normalized to the time-tension index of HG, providing a relative index of exercise pressor response magnitude (BPI norm ). Results BPI hg and BPI peco were significantly elevated in the third FFMi quartile ( p ≤ 0.034), while BPI norm significantly decreased in the second and fourth quartiles ( p ≤ 0.029). In contrast, no differences in BPI cpt were observed across any FFMi, BMI, or FMi quartiles ( p ≥ 0.268). FFM was independently associated with BPI hg, BPI peco , and BPI norm (all p ≤ 0.049), however, FFM was eliminated as an independent predictor when maximal voluntary contraction (MVC) was included in these regression models (all p ≥ 0.495). Neither FFM nor MVC was associated with BPI cpt ( p ≥ 0.229). Conclusions These findings indicate that exercise pressor responses, but not cold-pressor responses, are significantly associated with FFM in humans, and that this association is driven by FFM related differences in MVC
