“…Thus, acute moderate-intensity aerobic exercise before glucose ingestion might also not change in leg arterial stiffness arising after glucose ingestion. Low-(Sugawara et al, 2004) and moderate- (Maeda et al, 2008) intensity acute aerobic exercise decreases arterial stiffness. As far as the authors know, there is no report that arterial stiffness increased with acute low-and moderate-intensity aerobic exercise.…”

Arterial stiffness increases after glucose ingestion. Acute low- and moderate-intensity aerobic exercise decreases arterial stiffness. However, the acute effects of 30 min of cycling at low- and moderate-intensity [25% (LE trial) and 65% (ME trial) peak oxygen uptake, respectively] on arterial stiffness at 30, 60 and 120 min of a postexercise glucose ingestion. Ten healthy young men (age, 22·4 ± 0·5 years) performed LE and ME trials on separate days in a randomized controlled crossover fashion. Carotid-femoral (aortic) pulse wave velocity (PWV), femoral-ankle (leg) PWV, carotid augmentation index (AIx) and carotid blood pressure (BP) (applanation tonometry), brachial and ankle BP (oscillometric device), heart rate (HR) (electrocardiography), blood glucose (UV-hexokinase method) and blood insulin (CLEIA method) levels were measured at before (baseline) and at 30, 60 and 120 min after the 75-g OGTT. Leg PWV, ankle pulse pressure and BG levels significantly increased from baseline after the 75-g OGTT in the LE trial (P<0·05), but not in the ME trial. Insulin levels and HR significantly increased from baseline after the 75-g OGTT in both trials (P<0·05). Aortic PWV, carotid AIx, brachial BP and carotid BP did not change from baseline after the 75-g OGTT in both trials. The present findings indicate that aerobic exercise at moderate intensity before glucose ingestion suppresses increases leg arterial stiffness after glucose ingestion.

“…There are few published reports on the impact of exercise on arterial compliance derived from central pressure waveforms. Maeda et al (31) studied sedentary elderly women and found that compliance was not affected by exercise at baseline. However, following a training program it was noted that compliance did increase during exercise (31).…”

“…This reduced arterial stiffness may thus seem unlikely to be clinically meaningful. However, a decrease in arterial stiffness helps to increase cardiac output and thereby inhibits excessive BP rise, especially during acute exercise [16,71]. Therefore, the decreased arterial stiffness per se seems to have advantages at least for reduction of cardiovascular risks.…”

“…In addition, Thomson et al and Vedam et al have shown a significant reduction in augmentation index, used to assess arterial stiffness, in healthy men breathing hypoxic gas [12,13]. Similarly, regular aerobic exercise training is widely accepted to induce a decrease in arterial stiffness and/or enhancement of flowmediated vasodilation (FMD) [14][15][16][17][18][19]. Exercise under hypoxic conditions would thus seem likely to more effectively induce vascular adaptations (i.e., a decrease in arterial stiffness).…”

Vascular adaptations to hypobaric hypoxic training in postmenopausal women

et al. 2010

The objective of this study was to examine the effects of exercise training in hypoxia on arterial stiffness and flow-mediated vasodilation (FMD) in postmenopausal women. Sixteen postmenopausal women (56±1 years) were assigned to a normoxic exercise group (Normoxic group, n=8) or a hypoxic exercise group (Hypoxic group, n=8). The Hypoxic group performed exercise under hypobaric hypoxic conditions corresponding to 2000 m above sea level, and was exposed to these conditions for 2 h per session. Aquatic exercise was performed at an intensity of around 50% peak oxygen uptake for 30min, 4days per week, for 8 weeks. Arterial stiffness was assessed by brachial-ankle pulse wave velocity (baPWV), and FMD was evaluated by peak diameter of the popliteal artery during reactive hyperemia. After the 8 weeks of training, the Normoxic group showed no significant changes. In contrast, baPWV (P < 0.05) was significantly reduced and peak diameter (P<0.05) and %FMD (P<0.01) were significantly increased in the Hypoxic group after training. These results suggest that exercise training under mild intermittent hypoxic conditions could more effectively reduce arterial stiffness in postmenopausal women, compared with exercise training performed at the same relative intensity under normoxic conditions. Our data also indicate that hypoxic exercise training may induce vascular functional adaptation, for example an increase in FMD response. These findings therefore could have important implications for the development of a new effective exercise prescription program.
