Abstract :
Background: Ginger (rich in gingerols and shogaols) rhizomes have
been widely used as dietary spices and to treat different diseases in
Asia. Cinnamon (containing cinnamic aldehyde and cinnamyl aldehyde)
is used as spices and as a pharmacological agent in ancient medicine.
Intense exercise can result in oxidative damage to cellular compounds
and also muscle soreness. Efficacy of dietary ginger and cinnamon as
antioxidant agents and their effectiveness in exercise performance and
reducing muscle soreness have been investigated in limited studies on
humans. So we studied the effects of dietary ginger and cinnamon on
oxidative stress and exercise performance and body composition in
Iranian female taekwondo players.
Methods: Sixty healthy trained women, aged 13-25 years, were
enrolled in the 6 week investigation and randomly categorized in
three groups (cinnamon, ginger, or placebo) and received three grams
of ginger, cinnamon, or placebo powder each day depending on the
group they belonged. Human malondialdehyde (MDA) level, exercise
performance, and body composition were evaluated in the beginning
and at the end of the study and compared among the groups.
Results: Forty?nine of the participants completed the 6 weeks
intervention. There was minor decrease in MDA in cinnamon and
ginger group compared with the placebo group and significant increase
in exercise performance in ginger group (P < 0.01), and considerable
increase in skin fold in cinnamon groups (P < 0.01), whereas there were
significant accretion in BMI for ginger group (P < 0.1) and cinnamon
group (P < 0.05). No significant changes in MDA, EP, and BMI were
observed between groups over time. But there were specific changes in
skin fold between cinnamon and placebo group (P < 0.05) and cinnamon
and ginger groups (P < 0.05).
Conclusions: Six weeks administration of ginger and cinnamon in
athlete women did not show any significant change in MDA level, body
composition, and exercise performance as compared with the placebo
group.
