A review of the number of fibres per muscle measured to calculate mean architectural properties in 243 published studies. (A) From the studies that reported the number of muscle fibres used to calculate mean fibre length, 80.8% measured fewer than 25 fibres per muscle, with 38.9% measuring 5 fibres or fewer per muscle. Only 1.8% of the papers that reported their totals used over 250 fibres. (B) In addition, 99% of the 243 papers reported the mean fibre length, while only 1% reported the median.
