The effect of different intensities of aerobic exercise before glucose ingestion on subsequent cardio-ankle vascular index in active and inactive women

The improper nutrition and increased sedentary behaviors increases the risk of chronic diseases such as cardiovascular illness, hypertension, arterial stiffness, and diabetes. While physical activity as an intervention can be important in modulate these conditions. The aim of this study was to investigate the effect of different intensities of aerobic exercise before glucose ingestion on subsequent cardio-ankle vascular index (CAVI) in active and inactive women.

The present study was a quasi-experimental study with two groups, 27 women were selected, including 15 members of the Shahrood women’s futsal team as an active group and 12 non-physical education students of the Shahrood university of technology as an inactive group with an age range of 18 to 35 years. Two groups participated in a cross-sectional students for separate 3 days (running with 25, 65, and 85% of the maximal reserve heart rate). At each session, CAVI was measured first using a vascular screening device. In the next step, running on a treadmill (with one of the three selected intensities) was performed and after 15 minutes, 75 g of glucose was ingested. Further 15 and 45 minutes after glucose Ingestion, the second and third stages, CAVI was measured. To analyze the data repeated measures analysis of variance and Bonferroni post hoc tests at the significant level of p<0.05 were applied.

Although at the beginning of all three sessions, the CAVI of the inactive group was higher; glucose ingestion after exercise with two intensities of 25% (p=0.005) and 65% (p=0.01) caused a significant change in CAVI in the active group compared to the inactive group; this means that the reduction in CAVI following these two activities and glucose ingestion occurred in the active group.

It seems that the response pattern of active and inactive women, especially at low intensities of exercise to glucose Ingestion after exercise could be different.
