Abstract

The objective of this thesis was to test the hypotheses that in medicated, borderline-Stage 1 hypertensive individuals, 8 weeks of isometric handgrip (IHG) training (3X/week) would elicit reductions in resting and ambulatory blood pressure (BP), and that these reductions would be predicted by cardiovascular reactivity to an IHG task (a 2-minute sustained isometric contraction). Additionally, it was hypothesized that 4 weeks of detraining following 8 weeks of IHG training would lead to BP returning to baseline values. Cardiovascular reactivity to an IHG task was determined prior to IHG training, while resting BP and ambulatory BP were determined prior to and following 8 weeks of IHG training, and again after 4 weeks of no training (n = 4; resting BP: 134/77 ± 14/10 mmHg; age: 58 ± 2 years). IHG training did not elicit statistically significant reductions in BP (P > 0.05), and BP did not change following 4 weeks of detraining. Pre- IHG training cardiovascular reactivity to the IHG task was not strongly correlated to IHG training-induced changes in resting or ambulatory BP.
