Résumé
The use of strength training is important for athletes in combat sports such as judo
and jiu-jitsu. Specificity is key when prescribing strength training programs for
athletes, considering maximal strength, muscular power and strengthendurance.
Grappling combat sports require grip control, which is necessary to
execute throwing techniques and groundwork. The aim of this study was to
verify the bilateral strength deficit in general and in grappling combat sportspecific
action in the control group and grapplers. A sample of 73 subjects,
divided into 2 groups, was used: the Student Group (15 females and 16 males)
and the Grappler Group (29 males and 13 females). The male and female
participants attended four laboratory sessions over a 48-hour interval, the first
two to familiarize themselves with the Electromechanical Functional
Dynamometer (EMFD), and the last two to collect maximal isometric strength
data, using a standard grip and a judo/jiujitsu specific grip. Significant differences
in mean and peak forces (p < 0.001) were found, with high performance combat
sport athletes having greater maximal isometric strength compared to students
both bilaterally and unilaterally (p < 0.001). All comparisons also indicated higher
values for males compared to females (p < 0.001). The results suggest that
specific training in combat sports as well as sex differences play a significant
role in maximal isometric strength performance. The type of grip used affects
the application of force in the upper limb isometric strength tests, finding a
main effect of grip type (p < 0.001), with the standard grip obtaining higher
levels. However, the dominance between hands remains constant. More
research is needed on specific judogi/jiu-jitsu-gi grips and their impact on
maximal isometric strength with the EMFD.
