Introduction: Performing intense activities damages cells, and increased resting levels of oxidative stress indicators indicate damage to cell membrane function; therefore, the aim was to investigate the effect of eight weeks of jujube consumption and endurance exercise on oxidative stress indicators in inactive women after intense exercise
Methods: This is a semi-experimental study conducted with a pre- and post-test design. After obtaining written consent from 40 inactive female students, they were purposefully selected and randomly assigned to 4 groups of 10: endurance training + jujube consumption, endurance training, jujube consumption, and placebo. The subjects received 0.4 grams of jujube per kilogram of body weight daily. The training groups trained three days a week on a treadmill at an intensity of 55 to 75 percent of their heart rate reserve. Blood samples were taken before and after the intense activity under the same conditions, and the levels of creatine kinase and lactate dehydrogenase were measured by optical spectroscopy, malondialdehyde levels by spectrophotometry, and blood lactate by lactometer. Data were analyzed using one-way ANOVA and paired t-test in SPSS version 25 with a significance level of less than 0.05.
Results: The results showed that performing endurance activities along with jujube consumption significantly changed blood lactate levels at rest and after intense exercise (p<0.05), but did not significantly change creatine kinase, lactate dehydrogenase, and malondialdehyde levels (p>0.05).
Conclusion: The endurance exercise program probably did not affect cell membrane function, and jujube consumption may have reduced the effects of increased oxidative stress caused by intense exercise and prevented potential damage to the membrane.
