Conduction of electrical signals along the surface of muscle fibers is acknowledged as an essential neuromuscular component which is linked with muscle force production. However, it remains unclear whether muscle fiber conduction velocity (MFCV) is also linked with explosive performance. The aim of the present study was to investigate the relationship between vastus lateralis MFCV and countermo...

Muscle fiber conduction velocity (MFCV) estimation from surface signals is widely used to study muscle function, e.g., in neuromuscular disease and in fatigue studies. However, most analysis methods do not yield information about the velocity distribution of the various motor unit action potentials. We have developed a new method-the interpeak latency method (IPL)-to calculate both the mean MFC...

[Purpose] The aim of this study was to clarify the relationship between the muscle fiber conduction velocity (MFCV) obtained during muscle twitches from evoked potentials and the dynamic characteristics of muscular tension (muscle dynamic characteristics) by manipulating deep temperature. [Subjects] Subjects were 10 healthy adult men. Their mean age was 23.0 ± 3.9 years. [Methods] Measurement i...

Muscle fiber conduction velocity (MFCV) provides indications on motor unit recruitment strategies due to the relation between conduction velocity and fiber diameter. The aim of this study was to investigate MFCV of thigh muscles during cycling at varying power outputs, pedal rates, and external forces. Twelve healthy male participants aged between 19 and 30 yr cycled on an electronically braked...

The influence of five days' high-dose methylprednisolone therapy (2500 mg cumulative dose) on muscle fiber conduction velocity (MFCV) and muscle force was investigated in a group of patients without primary muscle involvement (MS-patients during a relapse). A significant decrease in MFCV was found. The decrease in MFCV was associated with a non-significant increase of the force of the investiga...

AIM AND METHODS We prospectively investigated whether early diagnosis of amyotrophic lateral sclerosis (ALS) could be facilitated by demonstrating signs of denervation in a muscle of a clinical and electromyographical unaffected region. Muscle fibre conduction velocity (MFCV) was determined in 18 patients in whom the diagnosis ALS was considered but not established beyond a level of clinically ...

Surface EMG, muscle fibre conduction velocity (MFCV), muscle force, and biochemical variables were investigated in a 13-year-old boy with familial hypokalaemic periodic paralysis during and after three attacks of paralysis. After normalisation of the serum potassium values, strength rapidly returned to interictal values, but the integrated EMG and to a lesser extent the MFCV recovered more slow...

PURPOSE The effects of exercise training on neuromuscular function of arm and leg muscles in type 2 diabetic patients (T2D) was investigated. METHODS Eight T2D sedentary male patients (61.0±2.3years) and eight sedentary healthy age matched control subjects (H, 63.9±3.8years) underwent a 16-week supervised combined endurance and resistance exercise program. Before and after training, maximal i...

The study was undertaken to provide insight into the mechanisms underlying the potentiation of the muscle compound action potential (M wave) after conditioning contractions. M waves were evoked in the tibialis anterior before and after isometric maximal voluntary contractions (MVC) of 1, 3, 6, 10, 30, and 60 s, and after 3-s contractions at 10, 30, 50, 70, 90, and 100% MVC. The amplitude, durat...

Surface EMG, muscle fiber conduction velocity (MFCV), muscle force and biochemical variables were investigated in a 13-year-old boy with familial hypokalaemic periodic paralysis (HOPP) during and after three attacks of paralysis. After normalisation of the serum potassium values, strength rapidly returned to interictal values, but the integrated EMG and to a lesser extent the MFCV recovered mor...
