Abstract
PURPOSE: The elite athlete is fine-tuned all around to deliver favorable results in sporting events. In this study, we address the question of whether basic movements-such as reflexes-and heterogeneous attentional modulation components-such as sensorimotor gating mechanisms-are also tuned up to maximize the results of middle-distance runners in physical conditioning tests. METHODS: We selected an array of professional middle-distance runners and healthy counterparts that were submitted to measurement of (1) physical conditioning parameters, including somatotype, jump, strength, and flexibility tests; and (2) sensorimotor gating mechanisms, including acoustic startle reflex, prepulse inhibition, and habituation. RESULTS: Our results showed athletes scored better on the athletic tests compared to controls, as expected. They also exhibited a lower startle amplitude, while maintaining higher prepulse inhibition values. They reacted faster to the acoustic stimuli, and sex-related differences-found in controls-were not present in athletes. Our data also pointed out to substantial correlations between sensorimotor gating and physical conditioning parameters. CONCLUSIONS: All in all, these data may point to physical conditioning-driven neural plasticity of brain sensorimotor gating circuits in charge of triggering involuntary movements to harness control and efficiency over reflexed muscle activity.
