“…This discrepancy is in agreement with the findings of others (L. V. Andreato et al, 2016;L. V. Andreato et al, 2015) and is likely partly caused by overestimated HR due to the intensity characteristics, body position, and repetitive isometric contractions during BJJ combat (Ovretveit, 2018a). In general, RPE is considered a reliable method for intensity assessments in combat sports (Slimani, Davis, Franchini, & Moalla, 2017).…”

“…Athletes were randomly selected from a larger cross-sectional study sample (Ovretveit, 2018b) for training intensity measurements. Perceptual and physiological markers were measured for five consecutive 6-minute sparring rounds separated by 90-second breaks against opponents of varying ranks, using instruments and procedures described elsewhere (Ovretveit, 2018a). Rating of perceived exertion (RPE) was used as a marker for perceptual effort and heart rate (HR) was used as a marker for physiological effort.…”

Problem statement: Brazilian jiu-jitsu (BJJ) is a grappling-based combat sport with a high attrition rate. Central to BJJ training is simulated competition in the form of sparring, which may have implications for athlete motivation and effort in training, and consequently impact skill development and sport adherence. Thus, the aim of this study was to Approach: Twelve active male athletes (age: 30.6 ± 2.7 (SD) years; height: 182.5 ± 5.9 cm; body mass: 81.2 ± 6.7 kg; training experience: 4.6 ± 2.2 years; weekly training duration: 10.3 ± 4.4 hours) ranked from white to brown belt were monitored during sparring in a BJJ training session. Perceptual training effort was expressed using rating of perceived exertion (RPE) and physiological training effort was determined with relative heart rate (HR) responses. Achievement goal profiles and perceptions of the motivational climate were assessed with the 3x2 Achievement Goal Questionnaire for Sport (3x2 AGQ-S) and the Perceived Motivational Climate in Sport Questionnaire (PMCSQ-2), respectively. Purpose: Explore the relationship between perceptual and physiological markers of training intensity and achievement motivation in active BJJ athletes. Results: The athletes reported a mean absolute RPE of 15 ± 1 during sparring, which equated to a relative RPE of 74 ± 7 percent. Mean HR was 164 ± 9 beats·min -1 , equivalent to 85 ± 4 percent of the athletes' maximal HR. Perceived effort strongly correlated with task-and self-approach goals, as well as other-avoidance goals (p < 0.05). Similar associations were observed for HR and the two latter goal constructs (p < 0.05). Conclusions:These observations indicate that mastery-based goals are associated with training effort in BJJ, consistent with previous findings on the mastery-effort relationship. Emphasizing mastery-oriented goals and motivational climates may increase long-term adherence to BJJ and be conducive to mastery involvement during training.

“…The effort pattern of BJJ is characterized by aerobic work at lower intensities interspersed with short bursts of high intensity (Andreato, Follmer, Celidonio, & Honorato, 2016). Despite several investigations of athlete characteristics (Andreato, Lara, Andrade, & Branco, 2017;Øvretveit, 2018b) and effort patterns in BJJ (Andreato et al, 2016;Øvretveit, 2018a), data on the health benefits, included the BP responses, of BJJ practise is scarce. Prado and Lopes (2009) found acute increases in BP following 20 minutes of BJJ sparring.…”

Hypertension is a leading preventable cause of morbidity and mortality worldwide. Exercise is a widely recommended treatment strategy that has been shown to cause both acute and chronic reductions in blood pressure. This study aimed to explore the potential therapeutic effects of Brazilian jiu-jitsu training by assessing blood pressure responses during and after technical sparring. Seven Brazilian jiu-jitsu practitioners (age: 24.0±3.5 years; height: 1.75±0.02 m; body mass: 76.0±4.2 kg; BMI: 24.5±0.9) were included in the study. The participants performed three five-minute technical sparring rounds. Auscultatory measurements of blood pressure were obtained at rest, one minute post-sparring, and every ten minutes for a total of 60 minutes of recovery time. Between rounds, acute increases in both systolic blood pressure (p<0.0001) and diastolic blood pressure (p<0.0001) were observed. In the subsequent recovery period, both systolic blood pressure and diastolic blood pressure increased at the ten-minute mark compared to baseline values, but then started to gradually decline, with systolic blood pressure dropping 10.0±4.1 (p<0.0001) and diastolic blood pressure 5.0±4.1 mmHg (p=0.001) after one hour of recovery. These findings indicate that technical Brazilian jiu-jitsu sparring induces significant post-exercise decreases in blood pressure and thus may have value as a non-pharmacological treatment strategy for the prevention and management of hypertension.

“…BJJ combat involves work at different intensities and requires frequent adjustments to changes in metabolic demand 2 . This requires both aerobic and anaerobic energy supply, with the maximal rate of aerobic adenosine triphosphate resynthesis appearing to be of particular importance to the sustainability of physiological performance 3 .…”

BACKGROUND: Despite regularly engaging in high-intensity grappling, Brazilian jiu-jitsu (BJJ) athletes have a moderate maximal oxygen uptake (V ̇O2max). The aim of this study was to evaluate the efficacy and feasibility of high-intensity aerobic interval training as an accessory to BJJ training for improvements in V ̇O2max. METHODS: Twelve active male BJJ practitioners (age: 30.3 ± 4.0 (SD) years; height: 183.0 ± 5.3 cm; body mass: 82.7 ± 8.3 kg; body fat: 11.9% ± 3.8%) with 5.6 ± 5.8 years of experience and a training volume of 9.9 ± 4.6 hours•week -1 were randomly allocated to either a training group (TG) or control group (CG). The TG incorporated two high-intensity aerobic interval training sessions•week -1 comprising four 4-minute intervals at 85-95% of maximal heart rate (HRmax) separated by 3-minute active breaks at 70% of HRmax. RESULTS: After six weeks, the TG increased their V ̇O2max by 8% ± 3% (95% CI = 3.84, 12.73; p = 0.04; ES = 0.64), from 52.7 to 56.8 ml•kg -1 •min -1 . This was accompanied by a 1% ± 1% reduction in absolute body fat (95% CI = -0.13, -2.2; p = 0.04; ES = 0.64). No changes in V ̇O2max (p=0.12) or body composition (p=0.34) were detected in the CG.CONCLUSIONS: These findings reveal compelling short-term effects of low-volume highintensity aerobic interval training on V ̇O2max and body composition in active BJJ athletes. There may be a ceiling effect in terms of developing V ̇O2max in supine, intermittent grappling sports, making alternative approaches to aerobic conditioning particularly relevant for this athlete population.
