AIMS: To evaluate the effects of isokinetic training on peak torque and maximum power of the flexor and extensor muscles of the knee and hip articulations in an athlete with lower limb amputation CASE DESCRIPTION: We assessed a 27-year-old triathlete amputee, with congenital amputation of proximal third of right tibia and user of high-performance prosthetics for running. The circumference of both lower limbs were measured, and an isokinetic dynamometer was used to estimate the peak torque and maximum power of the flexor and extensor muscle groups of the knee and hip, before and after two weeks of training with isokinetic exercises. There was a reduction in the coefficient of variation of all four repetitions of flexion and extension of hip and knee on both lower extremities, identifying a greater uniformity in torque curves on revaluation compared to the initial evaluation. CONCLUSIONS: Athletes with lower limb amputation should have an adjustment period with the isokinetic dynamometer in order to familiarize with the execution of concentric and eccentric movements. The absence or inefficiency of this adaptation can compromise data collection for the composition of protocols of treatment and / or training in amputee athletes.Downloads
