1. PHYSIOLOGY OF JUDO

2. WHAT IS JUDO ?
• Judo, one of the most popular sports in the world, is an
exciting grappling sport similar to wrestling, but unlike
wrestling, the competitors wear thick jackets called
judogis or gis.

3. RULES OF THE GAME
• Throwing an opponent onto his or her back with impetus.
• Holding an opponent down on his or her back for 25
seconds.
• Strangling an opponent into submission.
• Joint-locking an opponent into submission.

4. Throwing An Opponent Onto His Or Her Back
With Impetus.

5. Holding An Opponent Down On His Or Her
Back For 25 Seconds.

6. Strangling An Opponent Into Submission.

7. Joint-locking An Opponent Into Submission.

8. Game Analysis
In a match, about 11
effort sequences are
performed, with the
efforts and pauses
lasting approximately
30 and 10s,
respectively.

10. Game Analysis(Energy Systems)
Blood lactate values after match
simulations reach ~10 mmol/l
However, these values are
approximately 3 mmol/l lower than
those measured after real
competitions.

11. Game Analysis(Energy Systems)
• Another point to be considered regarding recovery
processes is the aerobic fitness.
• Gariod et al. (1995) reported that judo athletes with
higher VO2max presented a faster PCr resynthesis
compared to those with lower VO2max
• The aerobic fitness is also important for judo athletes in
the last minutes of the match, as well as in the extra-time
or to increase recovery between matches.

12. Game Analysis(Energy Systems)
• Medal winners in judo normally perform 5-7 matches in a
single day. Therefore, strategies to improve recovery
between matches are of great importance.
• the odds ratio of winning a match increased ten times
when a judoka performed AR and his opponent
performed PR, but the cause of this phenomenon
cannot be explained by changes in number of actions
performed or by changes in match’s time structure

judo tasks." European journal of applied physiology 107.4 (2009): 377.

combat athletes, such as judokas, wrestlers,
and boxers, are required not only to master
the specific moves in their sport, but also to
excel in a variety of physical abilities such
as quickness, balance, and explosive
power.

• In general, lower-body is involved in short-term high-intensity actions
during technique executions, while upper-body muscle groups are
involved in both strength-endurance and power actions

21. Judo Athlete Profile (Muscle Power)
• lower body power is important for judo performance, probably
because a powerful action is needed during many throwing
techniques.
• Vertical jump height ~50 cm

athletes." Sports Medicine 41.2 (2011): 147-166.

22. Judo Athlete Profile (Muscle Endruance)
• In judo, most of the studies on muscular endurance have evaluated
this capacity using sit-ups and push-ups

athletes." Sports Medicine 41.2 (2011): 147-166.
