Introduction: In the present study, the effect of strawberry extract on some oxidative, inflammatory and cellular damage indices due to acute resistance exercise in non-athlete women was investigated.
Materials: 14 healthy non-athlete girls in a randomized, double-blind, placebo-controlled, crossover study in two complementary and placebo conditions (height: 162.5 7 2.7, weight: 70.4 6 6.3, body mass index: 2/2) 26.7 ، 1, age: 24.7 3 3.5). Subjects took 350 mg twice daily for 14 days before a resistance training session with strawberry extract or placebo (maltodextrin) supplement. Serum blood samples were collected for total antioxidant capacity, malondialdehyde, reactive protein C and creatine kinase, before the supplementation period (baseline), before and after a session of acute resistance exercise.
Results: Total antioxidant capacity in complementary conditions before resistance exercise and after resistance exercise was higher than before supplementation (p <0.05). Malondialdehyde levels were higher than complementary conditions in placebo conditions and in the stages before resistance exercise and after resistance exercise (p <0.05). C-reactive protein did not change significantly (p <0.05). Creatine kinase levels in placebo conditions were higher after resistance activity than before supplementation and before resistance activity (p <0.05).
Conclusion: The results of the present study showed that strawberry extract supplementation may play a role in reducing cellular oxidative stress and cell damage due to strenuous exercise.
