Abstract

Background

The fencer performs the lunge, an attack characterized by a forward push.

Aims

The objective of the study was to compare the neuromuscular and proprioceptive variables between the front and back legs during the lunge.

Methods

It was a cross-sectional study of 19 fencers. Measurement of the concentric muscle torque peak of the ankle muscles, as well as muscle balance, through the conventional ratio and functional ratio, was performed through the isokinetic dynamometer. The reaction time (RT) of the peroneus longus (PL), anterior tibial (AT) and lateral gastrocnemius (LG) of both legs was collected from an electromyography during Lunge execution. Dynamic neuromuscular control of the ankles was evaluated by the Star Excursion Balance Test (SEBT) in eight different directions.

Results

It was possible to identify a significant difference in the muscular torque of these muscle groups (p ≤ 0.05), as well as in the Conventional Ratio (p = 0.002) and Functional Ratio (p = 0.003) of dorsiflexors/plantiflexors of the back leg in relation to the front, that is, a decrease in the force of back leg. There was also no difference in the RT of the PL and AT (p ≥ 0.05), but have difference in RT of LG during the Lunge (p ≤ 0.05). Furthermore, there is difference in the eight directions of the SEBT (p ≤ 0.05) comparing the back with the front leg.

Conclusions

The training performed by fencing athletes is not able to produce similar stimuli for both legs with regard to dynamic neuromuscular control, reaction time and concentric torque of the ankle musculature.
