Background Vertical jumps can be used to assess neuromuscular status in sports performance. This is particularly important in Cerebral Palsy Football (CP Football) because players are exposed to high injury risk, but it may be complicated because the gold standard for assessing jump performance is scarce in field evaluation. Thus, field techniques, such as mobile apps, have been proposed as an alternative method for solving this problem. Objective This study aims to evaluate the reliability of the measures of the MyJump2 app to assess vertical jump performance in professional CP Football. Methods We assessed 40 male CP Football athletes (age 28.1 [SD 1.4] years, weight 72.5 [SD 6.2] kg, and height 176 [SD 4.2] cm) through the countermovement jump (CMJ) and squat jump (SJ) using a contact mat. At the same time, we assessed the athletes using the MyJump2 app. Results There were no significant differences between the instruments in SJ height ( P =.12) and flight time ( P =.15). Additionally, there were no significant differences between the instruments for CMJ in jump height ( P =.16) and flight time ( P =.13). In addition, it was observed that there were significant and strong intraclass correlations in all SJ variables varying from 0.86 to 0.89 (both P <.001), which was classified as “almost perfect.” Similar results were observed in all variables from the CMJ, varying from 0.92 to 0.96 (both P ≤.001). Conclusions We conclude that the MyJump2 app presents high validity and reliability for measuring jump height and flight time of the SJ and CMJ in CP Football athletes.

Introdução: O futebol de 7 é um esporte intermitente no qual a capacidade de força é evidenciada, tornando a avaliação desta e outras capacidades essenciais para o alcance do desempenho esportivo. Objetivo: O objetivo deste estudo foi identificar o perfil antropométrico e do desempenho motor, por classe funcional e posição de atletas da seleção brasileira de futebol de 7. Metodologia: A amostra foi composta por 16 atletas. Na avaliação antropométrica foi medido: MC, estatura, IMC, pregas cutâneas e circunferência abdominal. Para o desempenho motor foram utilizados: saltos verticais, agilidade 10 x 5 e RAST test. Resultados: As variáveis antropométricas apresentaram média da MC de 69,6±7,3, IMC de 19,9±1,9, somatória de nove pregas 88,8±35,4 e %G 10,6±5,4. O desempenho motor apresentou resultados para agilidade de 18,9±1,1, Countermovement jump 33,4±8, Squat jump 31,6±7,6 e potência média 6,3±1,5. Conclusão: Os resultados se apresentaram adequados para atletas de alto rendimento e o desempenho motor sofreu influências da classe funcional.

Introduction: Football 5-a-side is a sport played by blind athletes that takes part in the Paralympic Games since 2004. The Brazilian national team is currently considered the best team in the world in this sport. Objective: To analyze the variations of intensity of effort (average per position and group average) made by blind athletes of the Brazilian football 5-a-side national team during six matches simulations. Methods: The sample on this research is the intentional type, made with eight blind male players,  ages ranging from 21 to 30 years old (23.8 ± 3.3), all of them part of the Brazilian Football 5-a-side National team, which played in the 2012 Paralympics Games in England. In was evaluated the VO2máx and the heart rate during six simulations of official matches. Results: The intensity of effort of the blind athletes of the Brazilian Football 5-a-side National Team is intermittent and remains 52.5 % of the total time of a match (50 minutes) with an intensity of effort between the zone 2 (between threshold ventilation and respiratory compensation point) and the zone 3 (above the respiratory compensation point) averaging 89.8 % of the HR max. Conclusion: The intensity of effort is greater than the Football of 11 and, that in the Futsal players.
