Identification of judo contest from physiological viewpoint
Journal Title: Journal of Combat Sports and Martial Arts - Year 2010, Vol 1, Issue 2
Abstract
[b]Introduction.[/b] The purpose of the research was to identify a judo contest from physiological point of view, based on examination of duration of sequences of activity and breaks within a great number of contests.[b]Material and methods. [/b]Time sequences of activity during judo contest were measured in seconds from command of the referee hajime to matte (soremade) in European Championships 1985 and 1986, World Cup 1986, Olympic Games 1988-1996, European Championships 1999 and Olympic Games 2008. Concentration of lactic acid in blood in third minute after completing the contest was measured in arterialized blood from a tip of the finger or the ear lap with enzymatic method (set of Boeringer tests) and acid-base balance with analyzer Corning 166 micro.[b]Results. [/b]Mean time of sequences of activity in a judo contest are within range of 18 to 25 seconds but breaks, about 10 seconds. High intensity intermittent short efforts during a judo contest cause that energy system of a competitor involves primarily anaerobic glycolytic systems, therefore training specificity is crucial in the adaptation of the system. The ability to recover quickly from anaerobic work is essential for competition success, since the total contest performed during a tournament may range from 5 to 8 matches. Then aerobic capacity of a judo competitor is higher than average to utilize quickly highly concentrated lactic acid in the judoka’s blood.[b]Conclusions.[/b] During a judo contest an energy is mainly delivered from anaerobic glycolytic system of a competitor, though aerobic capacity of a judoka is higher than average to utilize quickly lactic acid concentrated in blood.
