Objective This study was designed to investigate whether there are differences in body composition, flexibility, muscle strength and endurance between elite and non-elite Brazilian jiu-jitsu athletes. Methods Eighteen male brown and black belts Brazilian jiu-jitsu athletes were divided into two groups: elite group (EG) (n=8, 25±2 years old, 76±10kg) and non-elite group (NEG) (n=10, 24±4years old, 72±5kg). The sample performed assessments to estimate the body composition via skinfold thickness; maximal strength via 1-RM tests in the bench press and squat exercises; abdominal and upper limb strength endurance using 1-min sit-up and 1-min push-up tests, respectively; and flexibility by sit-and-reach test. Independent Student t test was used to compare groups and Cohen's effect size (d) was also calculated. Results Groups differed in the percentage of body fat (EG: 11.2±3.0%, NEG: 14.8±3.0%, P=0.049, d=1.20), bench press 1-RM (EG: 111±6kg, NEG: 98±6kg, P<0.001, d=2.17), 1-min sit-up test (EG: 46±4 reps., NEG: 40±3 reps., P=0.007, d=1.70), 1-min push-up test (EG: 41±3 reps., NEG: 36±3 reps., P=0.018, d=1.67) and sit-and-reach test (EG: 40±3cm, NEG: 32±3cm, P<0.001, d=2.67). The groups did not differ for the absolute maximal strength in the squat (EG: 91±8kg, NEG: 88±7kg, P=0.410, d=0.40) and relative maximal strength in the bench press (EG: 1.46±0.13kg/kg, NEG: 1.36±0.11kg/kg, P=0.096, d=0.40) and squat (EG: 1.20±0.13kg/kg, NEG: 1.23±0.13kg/kg, P=0.700, d=0.23). Conclusions The Brazilian jiu-jitsu elite athletes showed lower body fat percentage, higher abdominal and upper limb strength endurance, higher flexibility and absolute maximal strength in the bench press compared to non-elite athletes. |
