CARPES, F. P.; BINI, R. R.; MOTA, C. B. Training level, perception and bilateral
asymmetry during multi-joint leg-press exercise. Brazilian Journal of Biomotricity, v. 2,
n. 1, p. 51-62, 2008. This study was designed to investigate the training level,
perception and bilateral asymmetry of force applied on the pedals of a leg-press
machine during multi-joint leg-press exercise. Force data were acquired throughout the
exercise by means of an FSCAN system with sensitive insoles adapted to the right and
left pedals of a leg-press device and used to determine the bilateral asymmetry.
Perception of bilateral asymmetry was evaluated by means of an inventory including
two closed questions. Two groups according to their training experience were
considered: subjects adapted (n=8), and trained (n=8). The results suggest that trained
subjects present a smaller asymmetry index and a better perception of bilateral
asymmetries. Trained subjects presented better perception of bilateral asymmetries,
when it occurs during the exercise, than adapted subjects. The training seems to
influence the perception and reduce the bilateral asymmetries during the leg-press
multi-joint exercise.
