A positive family history of hypertension (+FH) is a risk factor for the future development of hypertension. Hypertension is associated with reductions in baroreflex sensitivity (BRS). Therefore, we hypothesized that young women with a +FH [n = 12, 22 ± 1 yr, body mass index (BMI) 21 ± 1 kg/m 2 , mean arterial pressure (MAP) 79 ± 1 mmHg] would have lower BRS compared with young women without a family history of hypertension (-FH) (n = 13, 22 ± 1 yr, BMI 21 ± 1 kg/m 2 , MAP 77 ± 2 mmHg, all P > 0.05 between groups). Continuous …

There are two key sources of information that can be used to match forces—the centrally generated sense of effort and afferent signals from mechanical receptors located in peripheral tissues. There is currently no consensus on which source of information is more important for matching forces. The corollary discharge hypothesis argues that subjects match forces using the centrally generated sense of effort. The purpose of this study was to investigate force matching at the shoulder before and after a suprascapular nerve block. The nerve block creates a sensory and muscle force mismatch between sides when matching loads. The torque matching accuracy …
