Using training impulse and monotony methods to monitor aerobic training load in rats

Abstract

This study is the first to apply training impulse (TRIMP) and Training Monotony (TM) methodologies, within the realm of sport science, in animal model studies. Rats were divided into Sedentary (SED, n=10) and Training (TR, n=13). TR performed a fourweek moderate-intensity interval training with load progression. Lactate kinetics, lactate training impulse (TRIMP Lac ), maximal speed training impulse (TRIMP Smax ) and TM were utilized to develop and monitor training protocol. TR showed an 11.9% increase in time to exhaustion at the second maximum incremental test and a 17.5% increase at the third test. External work was increased by 17.8% at the second test and 30.3% at the third.
