Purpose:

To determine the optimal interval between competitions for success in the different events of the judo world tour.

Methods:

A total of 20,916 female and 29,900 male competition participations in the judo world-tour competitions held between January 2009 and December 2015 were analyzed, considering the dependent variable, winning a medal, and the independent variables, levels of competition.

Results:

There was an increased probability of winning a medal when the interval was in the 10- to 13-wk range for both male and female athletes competing at Grand Prix, Continental-Championship, and World-Championship events, whereas for Grand Slam, only men had an increased probability of winning a medal in this interval range. Furthermore, men had increased probability of podium positions in Continental Championship, World Master, and Olympic Games when the interval was longer than 14 wk.

Conclusion:

Optimal interval period between successive competitions varies according to competition level and sex; shorter intervals (6–9 wk) were better for female athletes competing at the lowest competition level (Continental Open), but for most of the competitions, the 10- to 13-wk interval was detected as optimal for both male and female athletes (Grand Prix, Continental Championship, and World Championship), whereas for the ranking-based qualified male competitions (ie, Masters and Olympic Games), a longer period (>14 wk) is needed.
