The purpose of the present study was to investigate the correlations between a variety of markers of exercise intensity and reductions in resting blood pressure following isometric exercise training. Following institutional ethical approval, thirteen male participants performed a bi-lateral leg maximum voluntary contraction (MVC) during which peak electromyographic activity (EMGpeak) was identified. They then performed a discontinuous incremental isometric exercise test to volitional exhaustion before and after completion of a 4-week crossover training study. The incremental test comprised 2 minute stages and commenced at 10% EMGpeak, increasing by 5%EMGpeak at each stage. At exhaustion the mean torque for the final 2 minute stage (2min-torquepeak) and heart rate peak (HRpeak) were identified. Training involved 3 sessions per week (4 x 2 min bilateral-leg isometric exercise) at 95%HRpeak. Heart rate (HRtrain) and changes in EMG amplitude (EMGamp) and frequency (EMGfreq) were monitored from the first to second minute of each 2 minute training exercise bout. As markers of training intensity the mean training torque was expressed relative to the 2min-torquepeak (%2min-torquepeak) and training EMG was expressed relative to EMGpeak (%EMGpeak). At exhaustion the HRpeak was 110.6 ± 18.0 b.min-1 and 2min torquepeak was 108.0 ± 26.9 Nm. On average training was performed at 110.3 ± 22.3 %2min-torquepeak and 92.6 ± 9.3 %EMGpeak, and resulted in reductions in all blood pressure measures (-4.9 ± 5.8; -2.8 ± 3.2; -2.7 ± 2.4 mmHg for SBP, DBP and MAP respectively) Pre- post differences were assessed using paired sample t-test. SBP and MAP reductions correlated with %2min-torquepeak, EMGamp and EMGfreq but did not relate to %MVC or HRtrain. Differences in BP changes between the experimental and control condition were assessed using ANOVA within the ANCOVA test. An alpha level of < 0.05 was set as the threshold for statistical significance, and the Bonferroni post-hoc procedure was used to explore any significant differences detected. Pearson product moment correlation was used to explore relationships between blood pressure changes and HRtrain, %MVC, %2min-torquepeak, EMGamp and EMGfreq. Results suggest that enhanced resistance to local muscle fatigue was of utmost importance in defining the reductions in resting blood pressure observed after bilateral-leg isometric exercise training.
