Brazilian jiu-jitsu gi vs nogi – a comparative analysis of the motor fitness leveloOf athletes specializing in different fighting formats

<ns3:p>Background: Competition in Brazilian Jiu-Jitsu (BJJ) includes two formats: NoGi (shorts and grappling shirt) and Gi (kimonos). Identifying key motor fitness components is essential due to the specific physical demands of each format. The aim of this study was to assess the differences in motor fitness among BJJ athletes based on their specialization in different fighting formats (Gi vs. NoGi). Methods: Twenty-four male BJJ athletes were divided into two groups by fighting style: NoGi (n=12; age 23.321.25 years; training experience 5.501.88 years) and Gi (n=12; age 23.001.72 years; training experience 5.832.33 years). Motor potential was assessed using non-specific tests (Eurofit battery, computer-based test) and BJJ-specific tests (hanging on a judogi). Relative strength (SW) and anaerobic power (MPA) indices were also calculated. Results: The analysis showed significant differences in motor fitness between Gi and NoGi athletes (p&lt;0.05). The Gi group outperformed in grip strength and bent-arm hang (dc=0.95–1.04), while the NoGi group showed superior results in reaction time, explosive strength, and hybrid agility (dc=1.50–1.63). Other aspects were similar (p&gt;0.05), except for moderate advantages in anaerobic power (dc=0.40) for NoGi and relative strength indices favoring the Gi group (dc=0.70–0.77). Conclusions: NoGi athletes showed a strength-speed motor profile, while Gi athletes exhibited an endurance-strength profile, emphasizing upper-limb isometric endurance for gripping the judogi. These differences reflect distinct motor demands and adaptive strategies in BJJ sub-disciplines, supporting targeted diagnosis, interpretation, and training optimization based on specific performance profiles and sport-specific requirements.</ns3:p>
