Abstract Resume

Background:Some studies have already reported strong relationships between muscle power performance and specific combat-sport skills, especially in Olympic and Paralympic judo.
However, the proper evaluation of the muscle power normally depends on very-expensive equipment, such as force platforms and/or linear position transducers. On the other hand, the non-expensive and
practical vertical jump (VJ) test might be considered as a valid and reliable method for assessing lower limb explosiveness in top-level athletes. In addition, due to its user-friendly
characteristics, even athletes with visual impairments (who regularly need assistance to perform some specific motor tasks) may easily execute the VJs, which facilitate their implementation in
Paralympic assessment routines. Thus, the aim of this study was to investigate the correlations between muscle power and vertical jumping performance in Brazilian Paralympic Judo athletes.


Methods:Twelve Paralympic judo athletes with visual impairments, 6 women and 6 men (68.8 ± 14.7 kg; 166.5 ± 9.5 cm; 28.3 ± 8.3 years) were assessed in squat jump (SJ), countermovement
jump (CMJ), and mean propulsive power (MPP) in jump squat exercise. A Pearson correlation analysis was used to determine the relationships between VJ tests and MPP.


Results:The correlations between jump tests and MPP were 0.78 (CMJ and MPP) and 0.76 (SJ and MPP). 


Conclusions:The overall conclusion of this investigation is that there is a strong relationship between VJ performance and MPP. As a consequence, Paralympic coaches can use the VJ
tests to properly assess lower limb muscle power in their “judokas” with visual impairment.
