A79 TAKING CONTROL OF BREATHING: RESPIRATORY MUSCLES, INNERVATION, AND GAS EXCHANGE: Pitfalls In Using Paired Stimulations Of The Femoral Nerve To Quantify Quadriceps Force

In four patients (FEV1 39±7% predicted; mean±SE) and four healthy men, we recorded twitch forces elicited by single and paired stimulations after 15-20 minutes rest (non-potentiated twitches) and immediately after participants generated 10 to 100% maximum voluntary contraction (MVC) of knee extensio...

description In four patients (FEV1 39±7% predicted; mean±SE) and four healthy men, we recorded twitch forces elicited by single and paired stimulations after 15-20 minutes rest (non-potentiated twitches) and immediately after participants generated 10 to 100% maximum voluntary contraction (MVC) of knee extension. [...]voluntary quadriceps contractions produce less potentiation of paired twitches than of single twitches of the femoral nerve in elderly patients with COPD.
