Effects of arginine intake during weight training on blood variables

Abstract

This experiment studied the effect of arginine intake on blood pressure and blood variables during weight training in 20 men in their 20s. The re-sistance exercise program was performed 3 times a week at 60% of one repetition maximum for 8 weeks. The arginine intake group con-sumed 1,000 mg of arginine 2 tablets per day before weight training for 8 weeks. The placebo group was instructed to consume two of placebo with water, the same as the arginine intake group. After 8 weeks, the day after the end of the resistance exercise program, systolic pressure, diastolic pressure, total cholesterol, triglyceride, high-density lipopro-tein, low-density lipoprotein, muscle mass, and maximum muscle strength were measured. In changes in systolic blood pressure, the ar-ginine intake group was 118.20±2.40 mmHg, showed a statistically sig-nificant decrease compared to the placebo group. Triglyceride in the arginine intake group was 112.62±2.40 mg/dL, showing a statistically significant decrease compared to the placebo group. Based on these results, arginine intake during resistance exercise is judged to have a positive effect on lowering blood pressure, and is also believed to re-duce triglycerides, a blood lipid variable, so it is thought to function as a supplement during exercise.
