Background and purpose: The factors that control blood pressure, the most important of which are inactivity and improper nutrition. The present study was conducted with the aim of investigating the effect of arginine supplementation on blood pressure and glucose metabolism in elderly people with mild Hypertension. Materials and methods: 43 elderly men and women in the age range of 55 to 70 years with mild hypertension were selected as participants and were randomly divided into 4 groups, including the aquatic training group (AT), L-arginine supplementation (ARG), aquatic training + L-arginine supplementation (AT+ARG) and control (CON). AT group did sports training in water for 6 weeks. ARG group received 100 mg of L-arginine per body weight and AT+ ARG group received L-arginine supplement during 6 weeks of water sports training. The control group also received only placebo. The values measured in the present study included aerobic power, systolic blood pressure, diastolic blood pressure and fasting blood glucose. The findings were compared using one-way analysis of variance and Tukey's post hoc test at a significance level of ≥0.05. Results: The findings of the present study showed that the diastolic blood pressure of the subjects did not differ significantly (P=0.239), but the difference between the systolic blood pressure of the group was significant (P=0.031). Also, the change of fasting blood glucose of the samples in the 4 groups shows a significant difference (P=0.011). L-arginine consumption group and sports training + L-arginine consumption group showed a significant difference with the control group (P=0.0001 and P=0.001, respectively). Conclusion: The results of the present study showed that consuming L-arginine for 6 weeks in the elderly with hypertension can lead to improvement of their systolic blood pressure and fasting blood sugar, but adding training cannot double its effect. slow All sports training have proven effects in modulating blood pressure and lowering blood sugar in people who have used it for some time, but it seems that observing the double effect of activities on these indicators requires long training programs, which future studies show. It will clarify more.
