The aim of this study was to evaluate the effects of creatine supplementation associated or not with strength training upon lipid peroxidation in older women. This was a clinical, randomized, double-blind, placebo-controlled trial. Older women were randomly allocated into four groups: 1) placebo supplementation (PL, n = 10), 2) creatine supplementation (CR; n = 10), 3) placebo supplementation associated with strength training (PL + RT, n = 6) and 4) creatine supplementation associated with strength training (CR + RT, n = 8). Before (PRE) and after 24 weeks (POST), blood samples were collected to measure lipid hydroperoxides concentration by spectrophotometry. No statistical difference was observed on the lipid hydroperoxides concentration between groups (PL: PRE = 48.7 ± 36.9; POST = 29.3 ± 18.8; Δ = -13.0 ± 26.8; CR : PRE = 51.0 ± 46.0; POST = 54.2 ± 51.6; Δ = -8.6 ± 30.2; + PL TR: PRE = 33.0 ± 11.2; POST = 47.3 ± 31.6, Δ = 14.3 ± 39.2; CR + TR: PRE = 18.5 ± 10.1; POST = 28.1 ± 17.9, Δ = 9.7 ± 16.4 pmol.mg-1 of total protein, p = 0.17). Creatine supplementation associated or not with strength training did not affect the lipid peroxidation, an important plasmatic marker of oxidative stress, in elderly women.Downloads
