Our initial hypothesis was confirmed concerning improvements in upper-body anaerobic power and capacity (mean and peak power increase), lower-body muscle power (peak power increase)and strength endurance (isometric and dynamic grip strength endurance improvements) and body composition maintenance,but it was not confirmed concerning lower-body mechanical aerobic power maintenance.Concerning strength variables, the adaptation seems to be specific to the judo actions, as only row 1 RM increased and it is known that judo involves many pulling actions during the combat.Additionally, both isometric and dynamic strength endurance were improved by these athletes in a task involving the grip on the judogi, but not in non-specific strength endurance exercises (bench press and row repetitions at 70% 1 RM)
