Objective Progressive resistive exercises, such as the DeLorme or Oxford techniques, improve strength by adding weights to arrive at the ten-repetition maximum (10RM; DeLorme) or by starting at the 10RM and removing weight (Oxford). The goal of this study was to examine the efficacy of each training method.

Design In this randomized, prospective, group design, evaluator-blind clinical trial, 50 subjects performed either the Oxford or DeLorme weight-training techniques. Three times a week for 9 wks, subjects completed three sets of ten-repetition knee extensions based on the 10RM measured weekly. Incremental or decremental changes in training weight were utilized in training sessions based on the protocol randomly assigned to each subject.

Results The mean 10RM increase was 71.9 kg for the DeLorme group and 67.5 kg for the Oxford group, which was not significantly different. Examination with repeated measures multivariate analysis of variance revealed no significant difference between the two groups for 10RM increase, and no significant sex differences were found. Percentage change scores were not significantly different for 1RM and 10RM for both protocols and sexes.

Conclusion Both protocol groups were able to complete their lifting assignments and progressed similarly in weekly 10RM weight lifted. It can be concluded that both the DeLorme and Oxford protocols improve strength with equivalent efficacy. Further studies involving a larger sample size are needed to address potential sex-specific changes in strength improvement in response to the protocols.
