Aim: Considering the variety of nutritional supplements, choosing a suitable and available supplement for improving sports performance is important. Spinach is one such dietary supplement that contains inorganic nitrate/nitrite that appears to enhance vascular function, cognition, and physical performance. Therefore, this study aimed to investigate the effect of short-term consumption of spinach powder on the aerobic and anaerobic performance of active young individuals.
Methodology: After specifying the criteria for entering the research, 14 healthy and active men and women (age: 22.71±1.81 years, body mass index: 22.70±2.57 kg/m2) participated in this research. Once the subjects provided written consent, they were randomly assigned to two groups: supplement (50 g per day of spinach powder) and placebo (50 g per day of rice flour+green food powder). Both groups followed this regimen for 14 days. Before and 48 hours after the last dose of the supplement, the aerobic and anaerobic performance of the individuals' upper and lower bodies was evaluated using the Astrand ergometer test, Bruce treadmill test, 30-second Wingate cycling test, and 30-second hand crank test. To analyze the data, a 2×2 ANOVA test and Bonferroni pairwise comparisons were used in SPSS software version 26.
Results: The results of this study indicated that 14 days of spinach powder consumption had no significant effect on maximum oxygen consumption in maximal tests (P=0.59) and sub-maximal tests (P=0.08), as well as on peak (P=0.12), average (P=0.46), and minimum (P=0.63) anaerobic power, maximum pedal speed (P=0.55) and maximum speed retention time in the upper body (P=0.12) and lower body (P=0.97).
Conclusion: The results of this research showed that short-term consumption of spinach failed to improve the aerobic and anaerobic performance of active individuals. Therefore, the results do not support the use of spinach for enhancing athletic performance indicators.
