CNPq - Conselho Nacional de Desenvolvimento Científico e Tecnológico FAPESP - Fundação de Amparo à Pesquisa do Estado de São Paulo We aimed to profile the aerobic fitness and muscle power of five-a-side football athletes on the Brazilian National Paralympic Team. The sample consisted of 12 male Paralympic athletes on the Brazilian National five-a-side football team, including 3 sighted goalkeepers and 9 blind (B1 category) outfield players. The results were: peak oxygen uptake (VO2 peak), 51.8 ± 5.8 ml/kg/min; maximum speed, 17.1 ± 1.4 km/h and VO2 ventilatory threshold (VT), 40.2 ± 6.5 ml/kg/min The peak torque values (Nm) of the right and left legs were 241 ± 48 and 234 ± 45 for 60° extension, 127 ± 17 and 123 ± 16 for 60° flexion, 170 ± 29 and 162 ± 28 for 180° extension, 113 ± 13 and 109 ± 13 for 180° flexion, 130 ± 20 and 129 ± 23 for 300° extension, and 118 ± 17 and 115 ± 18 for 300° flexion, respectively. The five-a-side football players on the Brazilian National Paralympics Team exhibited physiologically normal responses to physical training related to the observed physical capacities as shown by the aerobic fitness and muscle power results observed. These results suggest that blind individuals can improve their physical capacity regardless of their visual impairment. Nosso objetivo foi avaliar a capacidade aeróbica e a força muscular dos atletas de futebol de cinco da Equipe Paralímpica brasileira. A amostra foi constituída por 12 atletas paralímpicos masculinos da equipe nacional de futebol de 5, incluindo 3 goleiros e 9 jogadores cegos (categoria B1). Os resultados foram: pico do consumo de oxigênio (pico de VO2), 51,8 ± 5,8 ml / kg / min; Os valores de pico de torque (Nm) das pernas direita e esquerda foram 241 ± 48 e 234 ± 45 para a extensão de 60 ° , 127 ± 17 e 123 ± 16 para fl exão de 60 °, 170 ± 29 e 162 ± 28 para extensão de 180 °, 113 ± 13 e 109 ± 13 para fl exão de 180 °, 130 ± 20 e 129 ± 23 para extensão de 300 ° e 118 ± 17 e 115 ± 18 para fl exão de 300 °, respectivamente. Os jogadores de futebol de 5 da equipe paralímpica brasileira apresentaram respostas fi siologicas normais frente ao treinamento físico relacionado às capacidades físicas observadas, conforme demonstrado pela capacidade aeróbia e os resultados de potência muscular observados. Estes resultados sugerem que indi-víduos cegos podem melhorar sua capacidade física, independentemente de sua defi ciência visual.

In the absence of light, as for totally blind people, some variables, such as body temperature, have an endogenous period that is longer than 24 h and tend to be free running. However, the circadian rhythm of muscle strength and reaction time in totally blind people has not been defined in the literature. The objective of this study was to determine the period of the endogenous circadian rhythm of the isometric and isokinetic contraction strength and simple reaction time of totally blind people. The study included six totally blind people with free-running circadian rhythms and four sighted people (control group). Although the control group required only a single session to determine the circadian rhythm, the blind people required three sessions to determine the endogenous period. In each session, isometric strength, isokinetic strength, reaction time, and body temperature were collected six different times a day with an interval of at least 8 h. The control group had better performance for strength and reaction time in the afternoon. For the blind, this performance became delayed throughout the day. Therefore, we conclude that the circadian rhythms of strength and simple reaction time of totally blind people are within their free-running periods. For some professionals, like the blind paralympic athletes, activities that require large physiological capacities in which the maximum stimulus should match the ideal time of competition may result in the blind athletes falling short of their expected performance under this free-running condition.
