The aim of this study was to investigate the effect of resistance training (RT) followed by a similar detraining period on the modulation of oxidative stress (OS) in obese older women. Fourteen obese women (age: 68.7 ± 4.8 years, body mass: 71.3 ± 14.8 kg, height: 156.3 ± 7.2 cm, body fat: 44.3 ± 4.4%) were submitted to 12 weeks of a RT program followed by a similar detraining period. Advanced oxidation protein products (AOPP) and total radical-trapping antioxidant potential (TRAP) were used as oxidative stress indicators. AOPP was not changed by RT or detraining (P = 0.31). Furthermore, TRAP was increased with RT (+ 15.1%; P < 0.001) and remained high even after 12 weeks of detraining (10.5%; P < 0.001). The results suggest that OS can be improved by RT and the 12-week detraining period does not seem to be enough to reverse adaptations induced by RT in obese older women.
