Abstract

Objectives: This paper examines high-volume aerobic exercise participation on the temporal stability of augmentation index (AIx). Methods: Six participants (25 ± 4 yr, VO2max = 56.0 ± 7.2 mL.kg-1.min-1) and a control group matched for age, height, weight and sex progressed from a modest weekly training load (4.9 ± 1.9 hr) of moderate/vigorous mixed modality physical activity to 18.3 ± 0.4 hr over a period of 8 wk. A control group maintained regular exercise and lifestyle.  Resting AIx, blood pressure and 30 km cycling time trials were tracked bi-weekly, with aerobic power measured pre-and post-intervention.  VO2max improved significantly (5.4%), while peripheral/central blood pressure, and resting HR remained unchanged. Performance improved significantly at week 2 and 4 with no improvement at weeks 6-8.  The AIx of the training group increased significantly between weeks 0, 4, and 8, while no changes occurred in the control. A progressively increasing volume of aerobic exercise training for 8 wk, appears to increase AIx, likely owing to an uncompensable training load induced stress.
