Análise do perfil físico e cinemático de praticantes de um programa de condicionamento extremo

Abstract

The present study aimed to I) identify changes in the movement pattern during the performance of OHS and possible differences between genders during a predefined protocol in extreme conditioning practitioners, II) determine the prevalence of injuries, analyze the profile of these practitioners and screening for associated injuries in practitioners of an extreme conditioning program, thus being able to identify a probable injury or risk factors for developing it. To achieve the first objective Eleven men (28.6 ± 4.5 years, 85.1 ± 8.4 kg, 1.80 ± 0.07 meters, 13.8 ± 7.7 months of practice) and eleven women (30.5 ± 4.8 years, 68.2 ± 10.36 kg, 1.70 ± 0.05 meters, 20.3 ± 17.01 months of practice) Crossfit practitioners. The protocol chosen for the training was the “Nautical Nancy” which consisted of 5 rounds of 15 overhead squats and 400 meters of rowing. During the exercise, an analysis was performed in which the shoulder, knee and hip flexion angles were analyzed in the first and last round. For men there was an increase in the shoulder and hip flexion angles and women increased the shoulder and knee flexion angles. For men there was an increase in the shoulder and hip flexion angles and women increased the shoulder flexion angles and a decrease in the knee flexion angle. These changes when practitioners are exposed to a session require attention, thereby reducing practitioners' exposure to injury risks. To reach the second objective, practitioners answered sociodemographic questions, related to the practice of the sport, related to injuries and the Sport Readiness Questionnaire with a Focus on Musculoskeletal Injuries (MIR-Q). 368 Crossfit practitioners were evaluated. In this sample, 57.33% were women, 54.61% of the practitioners answered YES in at least one of the MIR-Q questions, 48.91% reported pain / injury in at least one body segment. In this study, a moderate positive relationship was found between pain and the amount of affirmative responses in the MIR-Q and practitioners who reported positive for pain / injury had 2.76 more times to have responded positively to the MIR-Q. The injury rate (48.91%) found among the participants was similar to the injury rate in other studies with the same population and that more than half of the sample requires consultation with a specialist, based on the adopted screening method.
