ABSTRACT

The aim of this study was to determine and compare the ground reaction force (GRF) during conventional deadlift and hacklift. Twenty (n=20) recreationally active, resistance-trained men were recruited to this crossover design study and were instructed to perform both conventional deadlift and hacklift in random order. Participants were needed to lift 85% of their conventional deadlift one repetition maximum (1RM) score. One way repeated measure analysis of variances (ANOVA) was conducted to compare the differences of GRF during concentric and eccentric phase of both exercise. Results showed that the force production during concentric phase was significantly higher during traditional deadlift while no significant differences exist during eccentric phase. Findings of this study suggested that based on force production, performing conventional deadlift imposed better chances of strength adaptation.
