Oxygen uptake, heart rate, and blood lactate responses during 1,000 punches and 1,000 kicks in female collegiate karate practitioners.

Although many women engage in karate training (Atkinson, 1983), our understanding of metabolic demands of karate training is mostly confined to men because most karate studies used male subjects (Imamura et al., 1997; Imamura et al., 1999; Pieter et al., 1990; Schmidt and Royer, 1973; Stricevic et al., 1980; Zehr and Sale, 1993), whereas some studies that were found included female subjects (Gardecki et al., 1994; Shaw and Deutsch, 1982; The Scientific Research Group of the Committee on Improving Competitive Ability, Federation of All Japan Karate-Do Organizations, 1997 and 1998). In a previous study using male subjects (Imamura et al., 1997), we reported that heart rate (HR) responses during performing 1,000 punches and 1,000 kicks were moderate. The purpose of this study was to investigate oxygen uptake (V̇O2), HR and blood lactate responses and rate of perceived exertion (RPE) during 1,000 punches and 1,000 kicks in female black belt karate practitioners.
