PHYSIOLOGICAL CHARACTERISTICS OF ELITE JUDO ATHLETES AND ENERGY DEMAND DURING A JUDO COMPETITION. F. Felici1, M. Bruscolotti1, A. Di Mario2, V. Romanacci2, P. Sbriccoli1 The objective of this study was to compare the metabolic profile of top level judokas and the energy demand during a training routine simulating a judo match. Twelve subjects (six males, five females, age: 26.8±2.79yr; weight: 90.6±30.5 kg; stature: 1.77±0.1m) were selected from the national Olympic Club and subjected to three different tests. The first consisted of a graded maximal aerobic treadmill test (Bruce modified). During the test, maximal oxygen consumption (VO2-max), CO2 production, pulmonary ventilation (VE) and the respiratory exchange ratio (R) were assessed by a telemetric transmission metabolimeter (k4 Cosmed). In a second session, the anaerobic power was assessed by means of a Wingate test using a cycle-ergometer (Excalibur, Lode), and the peak power was determined; blood lactate concentration (La) was measured by a portable lactacidimeter at the beginning and at the end of each test, and through a 10-min. recovery. Finally, the athletes were tested during a simulated competition (approximately 4-min), during which La and heart rate (HR) were monitored. The mean VO2-max obtained was 50.75±3.65 and 48.1±9.93 ml*kg-1*min-1 in females and males, respectively. The peak power obtained during the Wingate test was 9.45±1.83 Watt*kg-1 in males, and 8.75±1.46 Watt*kg-1 in females. Differences in VO2-max and peak power between males and females were not significant. Blood La peaked within the first 6 minutes of recovery during the Wingate test, (mean: 6.91±2.16 mmol*l-1), whereas during the simulated competition the maximum La concentration was reached at the end of the test, (mean: 9.64±2.75 mmol*l-1) and was significantly higher (paired t-test, p<0.05) than that observed during the Wingate test. Complete recovery of all considered parameters was obtained within 15 minutes following each test. Following these findings, it might be concluded that in judo athletes, aerobic characteristics are mixed with anaerobic ones, and this is well in accordance with the intermittent features of judo competitions.
