Resistance exercise training attenuates exercise-induced lipid peroxidation in the elderly
Abstract . This study examined the effects of 6 months of resistance exercise ( RX ) on basal and post-aerobic exercise lipid peroxidation ( LIPOX ) .  Men and women [ n=62 , mean ( SD ) age 68.4 ( 6 ) years ] were divided r and omly into either a control ( n=16 , CON ) , low-intensity training [ LEX n=24 ; 50 % one-repetition maximum ( 1RM ) , 13 repetitions/exercise ] , or high-intensity training ( HEX n=22 , 80 % 1RM , 8 repetitions/exercise ) group . Pre- and post-training , subjects performed a grade d aerobic exercise test ( GXT ) . Blood sample s were collected prior to and 10 min following each GXT . Subjects trained 3 times per week for 6 months using 12 RX machines . LIPOX was determined by measuring levels of thiobarbituric reactive acid substances ( TBARS ) and lipid hydroperoxides ( PEROX ) . RX had no effect on resting LIPOX . Post-training , post-GXT TBARS were lower in the LEX and HEX groups by 14 % and 18 % , respectively , compared to CON ( P<0.05 ) . Post-GXT PEROX levels were lower ( P<0.05 ) in LEX and HEX compared to CON [ CON 3.51 ( 0.56 ) nmol/ml , LEX 2.89 ( 0.80 ) nmol/ml , HEX 2.99 ( 0.63 ) nmol/ml ] . Serum total and non-protein ( glutathione ) thiols were higher in the LEX and HEX groups following training compared to CON ( P<0.05 ) . These data suggest that RX can ( 1 ) reduce serum LIPOX , ( 2 ) provide protection against oxidizing agents in vitro , and ( 3 ) provide a " cross-protection " against the oxidative stress generated by aerobic exercise , perhaps mediated by improvements in the thiol portion of the antioxidant defense
