Abstract

The purpose of this study was to establish whether changes in resting blood pressure and the vasculature of trained and untrained limbs are dependent on training intensity, following isometric-leg training. Thirty middle-aged males undertook an 8 week training programme ( 4 × 2  min bilateral-leg isometric contractions 3 times per week). Two groups trained at either high (HI; 14%MVC) or low (LO; 8%MVC) intensity a third group (CON) acted as controls. All parameters were measured at baseline, 4-weeks and post-training. Resting SBP ( − 1 0 . 8 ± 7 . 9  mmHg), MAP ( − 4 . 7 ± 6 . 8  mmHg) and HR ( − 4 . 8 ± 5 . 9  b·min−1) fell significantly in the HI group post-training with concomitant significant increases in resting femoral mean artery diameter (FMAD; 1 . 0 ± 0 . 4  mm), femoral mean blood velocity (FMBV; 0 . 6 8 ± 0 . 8 3  cm·s−1), resting femoral artery blood flow (FABF; 8 2 . 0 6 ± 3 1 . 9 2  ml·min−1) and resting femoral vascular conductance (FVC, 45%). No significant changes occurred in any brachial artery measure nor in any parameters measured in the LO or CON groups. These findings show that training-induced reductions in resting blood pressure after isometric-leg training in healthy middle-aged men are associated with concomitant adaptations in the local vasculature, that appear to be dependent on training intensity and take place in the later stages of training.
