Objectives: Nordic walking (NW) is widely practiced by postmenopausal women. Its effects are peculiar owing to the involvement of more muscle groups than in traditional walking training (WT). Since mechanical load promotes secretion of vascular endothelial growth factor (VEGF) from both skeletal muscle and muscle endothelium, the aim of the study was to compare the effect of NW and WT on VEGF levels.Method: Thirty postmenopausal women were randomly assigned to NW or WT. Both groups trained 40-50min/day, three times per week, at a mean intensity of 12 on a 15-category scale of the ratings of perceived exertion. Since VEGF is also released from adipocytes, anthropometric parameters were assessed.Results: NW increased circulating VEGF more than WT (p=0.041). Furthermore, both study groups exhibited an average decrease in weight (p=0.023), body mass index (p=0.024), hip circumference (p=0.001), and arm fat index, although WT participants had higher values for this index at baseline (p<0.001) and thus exhibited a greater net decrease compared with the NW participants (p<0.011).Conclusions: These data imply that NW increases the level of circulating VEGF more than does traditional walking when the intensity of training is equivalent.

Abstract

Objectives: Nordic walking (NW) is widely practiced by postmenopausal women. Its effects are peculiar owing to the involvement of more muscle groups than in traditional walking training (WT). Since mechanical load promotes secretion of vascular endothelial growth factor (VEGF) from both skeletal muscle and muscle endothelium, the aim of the study was to compare the effect of NW and WT on VEGF levels.Method: Thirty postmenopausal women were randomly assigned to NW or WT. Both groups trained 40-50min/day, three times per week, at a mean intensity of 12 on a 15-category scale of the ratings of perceived exertion. Since VEGF is also released from adipocytes, anthropometric parameters were assessed.Results: NW increased circulating VEGF more than WT (p=0.041). Furthermore, both study groups exhibited an average decrease in weight (p=0.023), body mass index (p=0.024), hip circumference (p=0.001), and arm fat index, although WT participants had higher values for this index at baseline (p<0.001) and thus exhibited a greater net decrease compared with the NW participants (p<0.011).Conclusions: These data imply that NW increases the level of circulating VEGF more than does traditional walking when the intensity of training is equivalent.
