	abstract = {Characterization of the least number of muscle fibers analyzed for a quick and reliable, evaluation of intramuscular fiber conduction velocity (MFCV) is of importance for sport scientists. The aim of this study was to evaluate the reliability of vastus lateralis{\textquoteright} intramuscular MFCV measuring either 25 or 50 different muscle fibers per participant, as well as to compare intramuscular MFCV measured in 25 (C ), 50 (C ), or 140 (C ) muscle fibers. Resting vastus lateralis{\textquoteright} MFCV was measured in 21 young healthy males (age 22.1{\textpm}2.4~years) using intramuscular microelectrodes in different days. Test-retest reliability of MFCV{\textquoteright}s parameters was calculated for C and C , while MFCV was compared among C , C , and C . Significant differences of MFCV parameters were observed between C condition and those of C and C . The differences in MFCV values between conditions C and C were non-significant. A close correlation was found for MFCV between C and C (r=0.884-0.988, P=.000). All reliability measures of MFCV measured with 50 fibers were high (eg, ICC=0.813-0.980, P=.000), in contrast to C (eg, ICC=0.023-0.580 P>.05). In conclusion, an average of 50 different fibers per subject is sufficient to provide a quick and reliable intramuscular evaluation of vastus lateralis MFCV.},
