Abstract

Introduction: The purpose of this study was to examine and compare the effects of 3 days of dynamic constant external resistance (DCER) and isokinetic (ISOK) training and subsequent detraining on the electromechanical delay (EMD). Methods: Thirty-one men [age 22.2±4.2 years, body mass 77.9±12.9 kg, height 173.9±5.4 cm (mean±SD)] were randomly assigned to a DCER training group, ISOK training group, or control (CONT) group. Results: No significant changes were found for EMD from pre- to posttraining assessments 1, 2, and 3 [4.5±0.2 ms, 4.7±0.2 ms, 4.5±0.1 ms, 4.5±0.2 ms, respectively (mean±SE)] (P>0.05). Conclusions: It can be hypothesized that increases in strength observed after a short-term resistance training program may not be attributed to stiffness changes in the series-elastic component.
