Objective: To evaluate the effects of “strength-velocity” training on the evolution of some cardiorespiratory parameters in postpubertal judoists of the Congolese national elite. Methods: The survey, exploratory, experimental and longitudinal, was about 14 boys, belonging to seven categories of weight of the International federation of Judo. These judoists, at the level belonged to stages 3, 4 and 5 of the classification to Tanner, of pubertal maturation. Their median age was 16 years (range: 15 - 17 years). All topics have been submitted to “strength-velocity” training, focused around exercises bound to the development of the power and automatisms, from plyometric and isometric training. Three assessments have been realized in the beginning, to mid-training (3 months) and at the end of the program (6 months). The measured values were cardiorespiratory parameters. Results: The heart rate to the doorstep was decreased significantly (p = 0.048), so VO2 max (p = 0.046), fVC (p = 0.0244) and ratio VEMS/fVC (p = 0.046) as function of pubertal stage. In contrast, increase was not significant for VEMS (p = 0.205) and absolute VO2 to doorstep (p = 0.097). No significant effect of pubertal state on respiratory frequency was found. On the other hand, strength-velocity training improved cardiorespiratory data. To the recovery of the “strength-velocity test”, the decrease of the VO2 took place more quickly that the one of the VE, the VCO2 and the HR, variations linked to the category of topic weight. Conclusion: Among high level Congolese postpubertal judoists, the cardiorespiratory modifications induce faculty to the realization of a good performance and pursue objectives of health. However, it is necessary to be heedful as for situations to put in place in sittings at the time of such of “strength-velocity” training.
