Preensão palmar de praticantes de Brazilian Jiu-Jitsu em função do nível técnico

Abstract

The human hand has unique characteristics that contribute to handgrip strength (HGS), which is essential in sports such as Brazilian Jiu-Jitsu (BJJ). This research aims to compare HGS among BJJ practitioners of different technical levels. The study will be conducted with male amateur athletes, using a digital dynamometer to measure HGS in the dominant and non-dominant hands. Statistical analysis used one-way ANOVA to assess differences between groups. The results demonstrated a statistically significant difference between the hands (dominant vs. non-dominant), but did not identify significant differences in HGS values between the different technical levels (bands). Although the literature indicates a correlation between high sports performance and higher HGS, the findings of this study did not show an increase in grip strength with technical progression. Limitations such as the small sample size, the cross-sectional nature of the study, and the absence of women may have influenced the results. It is concluded that, although FPM is relevant in BJJ, there was no statistical difference in its magnitude between the technical levels analyzed.
