Abstract

The aim of this study was to assess the effects of two modes of antecedent flexibility conditioning on neuromuscular and sensorimotor performance during a subsequent episode of exercise-induced muscle damage (B1MD). Twenty-four males (age 20.9 +/- 2.3 years; height 1.78 +/- 0.06 m; body mass 72.3 +/- 7.4 kg, mean SD) were randomly assigned to interventions comprising 6 weeks of thrice-weekly flexibility conditioning of the hip region and knee flexor musculature in the dominant limb involving proprioceptive neuromuscular facilitation (n = 8), passive exercise (n = 8), or no exercise as a control (n = 8). Musculoskeletal, neuromuscular, and sensorimotor assessments were carried out at baseline, after conditioning, and before and up to 168 hours after damaging exercise of the ipsilateral knee flexors. Flexibility conditioning and E1MD elicited transient performance decreases in volitional electromechanical delay (up to 40.1% compared to baseline; 67.5 +/- 12.3 milliseconds vs. 47.9 +/- 9.7 milliseconds, mean SD, 48-hour post- vs. pre-014D; p <0.01), passive hip flexibility (up to 19.9%; 96.7 +/- 8.2 vs. 120.7 +/- 11.0, p <0.001) and sensorimotor capability (manifold error increase to 10.8%; 10.8% 6.9% vs. 0.3% 3.7%, p
