ABSTRACT
The evaluation models and protocols which supply with experimental data the movement theories, are still incompleted, just like biomechanical research, which needs standard methods. For a good sport movement evaluation, four different levels emerge: measuring, description, monitoring e analysing the results. In general for all evaluation levels human participation is requested. The concern about improving biomechanical measuring methods refles on the search for more accurate proce dures [ analyse sport movement. The measuring tests and protocois are based on lhe foUowing methods in BÍomecl anthropometry, kinematics. dynamícs and electromyography. Another con cern is to state strategies about standardizing evaluation protoCois for the biomechanicai laboratories associated lo Centros de Excelência Esportiva do Ministério de Esporte e Turismo (CENESP-MET). Those concerns may improve the scientific support for the deveiopment of sport in Brazil

The present study aims at describing the dynamic and temporal responses related to ground reaction force during gait in treadmill in two distinct groups: diabetic neuropathic patients and control subjects. We used an instrumented treadmill (Kistler) and its software to obtain temporal, spatial and dynamic parameters during gait. Our findings suggest that the biomechanical locomotor behaviour of the neuropathic subjects is significantly different from the control subjects: lower values of vertical forces, longer temporal parameters and shorter step and stride lengths. These altered biomechanical responses were found bilaterally. They were different from what we expected and found to be related to somatosensorial deficits in neuropathic patients. These findings can indicate that the disease compromises not only the mechanical behavior during gait but also the peripheral control of movement.

The purpose of this study was to analyze biomechanical aspects of futsal shoes since they were brand new until their total wastage. Ground reaction forces were measured (1 000 Hz) using a force plat- form (Kistler, type 9287 A) with a BIOWARE system program (Kistler, type 282Al-20), and a 12-bit AD conversor. As results, we highlight the increase for the following variables: vertical force first peak (17.26), loading rate 1 (56.25), vertical force second peak (3.43), vertical force increment (14.81), loading rate 2 (25), and the decrease of time to first peak of vertical force (22.5). However, the intra-subject analysis have shown that some subjecis kept satisfactory biomechanical conditions during movement tasks to overcome the shoe wastage. As conclusion, we have verified that sport shoes influence in human movement may be not more expressivo than the locomotor system itself.

O estudo sistematiza metodologia paar auxiliar na interpretação de parâmetros biomecânicos como possíveis interventores na avaliaçào de indivíduos portadores de neuropatia diabética. A avaliação biomecânica da distribuição da pressào plantar e da força de reação do solo, assim como a determinação de limiares de sensibilidade somato-sensorial e dor na superfície plantar, parecem ser os mais apropriados para identificar pacientes com risco evolutivo de desnvolver essa doença e evitar suas futuras complicações (au)
