The purpose of this study was to examine the effects of modified gradual overload training on performance (squat, snatch) and biochemistry factors(blood lactate, stress related hormones) in elite weight lifters. All subjects (n=16, Age: 24.1±4.3yr; height: 176.5±3.3㎝; Weight: 81.8±19.31㎏; Career: 9....

The purpose of this study was to examine the effects of modified gradual overload training on performance (squat, snatch) and biochemistry factors(blood lactate, stress related hormones) in elite weight lifters. All subjects (n=16, Age: 24.1±4.3yr; height: 176.5±3.3㎝; Weight: 81.8±19.31㎏; Career: 9.9±2.3yr) were participated normal (GT) or modified gradual overload training(M-GT) during six weeks (6 time week-1, 2~hour/day). The 1RM of squat and snatch was markedly increased when applied M-GT training compared to that of GT. blood lactate level after squat 1RM test was significantly higher immediately after 1RM test and all recovery time course in M-GT. blood lactate level in M-GT after snatch 1RM test was same as squat 1RM test except for immediately after and 3, 5min recovery time compared to GT. Blood IGF-1 level has no significantly difference between GT and M-GT. Interestingly, Serum norepinephrine and cortisol level were significantly decreased when applied M-GT. these results showed that M-GT may improve weight lifting performance which is not because of growth related hormone but stress related hormone.
