Introduction: Intense physical activity can cause cellular damage, leading to elevated resting oxidative stress and impaired cell membrane function. This study aimed to determine the effects of eight weeks of jujube supplementation and endurance exercise on oxidative stress indicators in inactive women after intense exercise.
Materials and Methods: This semi-experimental study was conducted using a pre- and post-test design. After obtaining written consent from 40 inactive female students, they were purposefully selected and randomly assigned into four groups of 10: endurance training + jujube consumption, endurance training, jujube consumption, and placebo. The participants received 0.4 g of jujube per kg 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 (CK) and lactate dehydrogenase (LDH) were measured by optical spectroscopy, malondialdehyde (MDA) levels by spectrophotometry, and blood lactate by lactometer. The collected data were analyzed using one-way ANOVA and paired t-test in SPSS (version 25).
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). However, it did not significantly change the levels of CK, LDH, or MDA (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.
