Abstract
Although high-intensity resistance training increases arterial stiffness, low-intensity
resistance training reduces arterial stiffness. The present study investigates the
effect of low-intensity resistance training before and after high-intensity resistance
training on arterial stiffness. 30 young healthy subjects were randomly assigned to
a group that performed low-intensity resistance training before high-intensity resistance
training (BLRT, n=10), a group that performed low-intensity resistance training after
high-intensity resistance training (ALRT, n=10) and a sedentary control group (n=10).
The BLRT and ALRT groups performed resistance training at 80% and 50% of one repetition
maximum twice each week for 10 wk. Arterial stiffness was measured using carotid-femoral
and femoral-ankle pulse wave velocity (PWV). One-repetition maximum strength in the
both ALRT and BLRT significantly increased after the intervention (P<0.05 to P<0.01).
Both carotid-femoral PWV and femoral-ankle PWV after combined training in the ALRT
group did not change from before training. In contrast, carotid-femoral PWV after
combined training in the BLRT group increased from before training (P <0.05). Femoral-ankle
PWV after combined training in the both BLRT and ALRT groups did not change from before
training. These results suggest that although arterial stiffness is increased by low-intensity
resistance training before high-intensity resistance training, performing low-intensity
resistance training thereafter can prevent the increase of arterial stiffness.
