The role of capsaicin-sensitive muscle afferents in fatigue-induced modulation of the monosynaptic reflex in the rat
TL;DR: It is concluded that the monosynaptic reflex inhibition, but not the enhancement, was mediated by those group III and IV muscle afferents that are sensitive to the toxic action of capsaicin.

Kv1.1 knock-in ataxic mice exhibit spontaneous myokymic activity exacerbated by fatigue, ischemia and low temperature
O. Brunetti,Paola Imbrici,Fabio Massimo Botti,Vito Enrico Pettorossi,Maria Cristina D'Adamo,Mario Valentino,Christian Zammit,Marina Mora,Sara Gibertini,Giuseppe Di Giovanni,Richard Muscat,Mauro Pessia +11 more
TL;DR: Findings provide direct evidence that identifies the motor nerve as an important generator of myokymic activity, that dysfunction of Kv1.1 channels alters Ca2 + homeostasis in motor axons, and also strongly suggest that muscle fatigue contributes more than PNS fatigue to exacerbate theMyokymia/neuromyotonia phenotype.

Voluntary Enhanced Cocontraction of Hamstring Muscles During Open Kinetic Chain Leg Extension Exercise Its Potential Unloading Effect on the Anterior Cruciate Ligament
Andrea Biscarini,Paolo Benvenuti,Fabio Massimo Botti,Antonella Brunetti,O. Brunetti,Vito Enrico Pettorossi +5 more
TL;DR: In leg extension exercises with resistance R≤ 40% 1RM, coactivation of the BF, SM, and ST can be significantly enhanced (up to 2, 3, and 4 times, respectively) by a voluntary hamstring cocontraction effort, which can completely suppress the anterior TF shear force developed by the quadriceps during the exercise.

Inhibition of muscle spindle afferent activity during masseter muscle fatigue in the rat
O. Brunetti,Giovannella Della Torre,Maria Luisa Lucchi,Roberto Chiocchetti,Ruggero Bortolami,Vito Enrico Pettorossi +5 more
TL;DR: It is concluded that fatigue signals originating from the muscle and traveling through capsaicin-sensitive fibers are able to diminish the proprioceptive input by a central presynaptic influence.

Focal vibration of quadriceps muscle enhances leg power and decreases knee joint laxity in female volleyball players.
O. Brunetti,Fabio Massimo Botti,Mauro Roscini,A Brunetti,Roberto Panichi,G. M. Filippi,Andrea Biscarini,Vito Enrico Pettorossi +7 more
TL;DR: Combined bilateral voluntary contraction and rMV of the quadriceps muscles is a short-lasting, non-invasive technique that can significantly and persistently improve muscle performance and knee laxity in volleyball women players.
