dc.description.abstract The aim of this retrospective study is to know the relationship between body weight (BMI, %BF) with blood pressure (SBP, DBP) and performance (VO ₂ max, PWC₁₇₀, FCR, etc...) among judo practitioners. Our sample represents 100 performance athletes, male (20-28 years) The sample was divided in two groups according to the percentage of body fat (20%). It was found that weight, BMI and % BF positively affect blood pressure (SBP, DBP) and performance (VR, CTR, FCR, etc...). The linear regression analysis revealed a very highly significant result (p <0.0001) between% BF, BMI and blood pressure, so there is a cause and effect relationship between indicators of adiposity and tensional elevation in studied athletes, in addition the BMI appears to be higher as an indicator of adiposity associated with cardiovascular risk (hypertension) compared with % BF and it does not accord with the different studies because BMI is influenced by other factors than body fat. The model results were highly significant but the determining factor was little, it lead us to say that there are genetic dispositions and other factors absent in the model, we can also say that the measure of body fat with skinfolds is unreliable and we must use other equations or other laboratory methods. The maximum volume of oxygen and the physical work capacity were higher among athletes with optimal weight, the linear regression models showed the superiority of weight compared to other parameters, which lead us to say that there is a perfect linear relationship between weight and VO₂ max. Were found in this study that the athletes have elevated resting heart rate and low consumption of maximum oxygen for high-ranking of judo practitioners , this suggests that the decline in VO ₂ max and HR is due to under-training and it explains why the BMI is the best indicator of adiposity despite the sample consists of elite athletes. -Conclusion: Finally, the morphological parameters (% BF, BMI) represent a key factor for success in athletic competition and in the prevention of risk factors for cardiovascular disease (hypertension). en_US
