Review of the Repeated Bout Effect in Trained and Untrained men

Abstract: High intensity exercise and especially eccentric contractions, produce muscle damage that can be demonstrated by indirect markers such as changes in neuromuscular performance, increased intramuscular proteins in the bloodstream, and delayed onset muscle soreness (DOMS). On the other hand, when exercise sessions are performed repeatedly there is a reduction in the responses of indirect markers of muscle damage, a phenomenon known as the protective effect (repeated bouts effect; RBE). A mong the adaptive mechanisms involved in RBE are neural, cellu lar and mechanical adaptations. However, data related to these adaptations are not yet conclusive. A significant range of studies that evaluated the RBE emp loyed subjects untrained and/or unaccustomed to physical exercise with a few research studies fro m the trained population, which already have chronic neuromuscular adaptations. Thus, the present review addresses the issue by bringing up to date information about the protective effect both when performed by untrained and trained populations. The data indicate that there is a reduction in the magnitude of indirect markers of muscle damage when the trained population conducts repeated exercise sessions compared to untrained and/or sedentary individuals.A mong the adaptive responses involved, the neural theory appears to be the main mechanism involved in mit igating the indirect markers of muscle damage.
