Background and Study Aim: In Brazilian Jiu-Jitsu (BJJ) competitions are based in two models accordingly to permitted clothing. The aim of this study was knowledge about physical and physiological responses, as well as the time-motion structure and technical-tactical actions induced by gi (traditional uniform) and nogi (where “gi” it is not permitted) simulated combats
Material and Methods: Twelve male athletes (age: 23 ±5 years, body mass: 81 ±8 kg, time of practice: 8 ±2 years) in two different conditions of simulated combats (gi and nogi). Blood lactate, heart rate, lower limbs power, strength and endurance handgrip were collected to asses physical and physiological demands. Additionally, technical-tactical and time-motion was analysed.
Results: Considering the physiological responses showed significant differences between moments (p<0.001), but not between conditions (p = 0.14 for heart rate, and p = 0.57 for blood lactate). For technical-tactical variables, differences between groups were restrict to successful takedowns (p = 0.04), were nogi condition showed higher frequency. Considering time-motion, only pauses were different between conditions, in which gi condition showed higher total time of pause (p = 0.02) and in percentage of total time (p = 0.02).
Conclusions: Despite modest physiological (HRmean), technical-tactical (takedowns) and time-motion (pause time) differences, BJJ matches induced similar responses when gi and nogi conditions are compared.
