    Creatine supplementation decreases oxidative DNA damage and lipid peroxidation induced by a single bout of resistance exercise.Rahimi R. J Strength Cond Res. 2011 Dec;25(12):3448-55. Department of Physical Education and Sport Science, University of Kurdistan, Sanandaj, Iran; and Department of Exercise Physiology, Faculty of Physical Education and Sport Science, University of Guilan, Rasht, Iran.

    Rahimi, R. Creatine supplementation decreases oxidative DNA damage and lipid peroxidation induced by a single bout of resistance exercise. J Strength Cond Res 25(12): 3448-3455, 2011-Creatine (Cr), or methyl guanidine-acetic acid, can be either ingested from exogenous sources, such as fish or meat, or produced endogenously by the body, primarily in the liver. It is used as an ergogenic aid to improve muscle mass, strength, and endurance. Heretofore, Cr's positive therapeutic benefits in various oxidative stress-associated diseases have been reported in the literature and, recently, Cr has also been shown to exert direct antioxidant effects. Therefore, the purpose of this study was to investigate the effects of an acute bout of resistance exercise (RE) on oxidative stress response and oxidative DNA damage in male athletes and whether supplementation with Cr could negate any observed differences. Twenty-seven resistance-trained men were randomly divided into a Cr supplementation group (the Cr group [21.6 ± 3.6 years], taking 4 ? 5 g Cr monohydrate per day) or a placebo (PL) supplementation group (the PL group [21.2 ± 3.2 years], taking 4 ? 5 g maltodextrin per day). A double-blind research design was employed for a 7-day supplementation period. Before and after the seventh day of supplementation, the subjects performed an RE protocol (7 sets of 4 exercises using 60-90 1 repetition maximum) in the flat pyramid loading pattern. Blood and urine samples taken before, immediately, and 24-hour postexercise were analyzed for plasma malondialdehyde (MDA) and urinary 8-hydroxy-2-deoxyguanosine (8-OHdG) excretion. Before the supplementation period, a significant increase in the urinary 8-OHdG excretion and plasma MDA levels was observed after RE. The Cr supplementation induces a significant increase in athletics performance, and it attenuated the changes observed in the urinary 8-OHdG excretion and plasma MDA.

    These results indicate that Cr supplementation reduced oxidative DNA damage and lipid peroxidation induced by a single bout of RE.

    "Να θυμάστε ότι αυτό που κάνετε είναι κάτι που ελάχιστοι άνθρωποι στον κόσμο έχουν τη δύναμη της θέλησης ή την αποφασιστικότητα να πραγματοποιήσουν. Χρειάζεται κάτι πολύ περισσότερο από τη σωματική μας δύναμη για να χτίσουμε και να σμιλέψουμε το σώμα μας. Χρειάζεται και μια τεράστια ποσότητα πνευματικής δύναμης, και αυτό είναι που οι υπόλοιποι άνθρωποι πραγματικά ζηλεύουν. Πάρτε το ως κοπλιμέντο, διότι ξεχωρίζετε μέσα σε ένα πλήθος ατόμων που μόνο ξέρουν να είναι ακόλουθοι."

    "Just remember that you are doing something that so few people in the world have the will power or determination to do. It takes much more than physical strength for us to build and sculpt our bodies. It takes an enormous amount of mental strength as well, and that's what people are truly jealous of. Take it as a compliment, for you stand out in a crowd full of followers."

    "You got a dream, you gotta protect it. If people can't do something themselves, they wanna tell you that you can't do it. If you want something, go get it. Period."
