Interpretation and perception of two different kumite fighting intensities through an integrated approach training in international level karatekas : an exploratory study

Summary .— “Small sided games,” used eff ectively in many team sports as a form of training, can be mimicked in combat sports by fi ghting at diff erent subjective intensities, based on adjectives proposed by coaches. This approach could aim at improving aerobic performance by using specifi c techniques. Nevertheless, an adequate perception of intensity is crucial. The aim of the study was to verify the ability of karatekas to interpret and perceive two diff erent intensities during this integrated approach. Ten international level karatekas ( M age = 18 yr., SD = 3, range = 16–25) were asked to fi ght four matches (2 min. each) either at low or highest intensity. Physiological (heart rate, blood lactate) and perceptual (perceived eff ort) responses were diff erent between intensities. However, physiological responses at low intensity were higher than expected and did not match eff ort perception. This could be attributable to the presence of an opponent, which probably raised the level of eff ort through a competitive component. At the highest intensity, physiological responses were similar to offi cial competitions and other specifi c training protocols, whereas perceptual responses were higher than values found in literature.
