Table 2 Muscle function and fatigability characteristics

From: Muscle function and fatigability of trunk flexors in males and females

   Females (n = 18) Males (n = 15)
Baseline MVC at zero position Nm 49.5 ± 22.2 57.3 ± 23.8
Baseline MVC normalized to trunk lean mass/height from DXA Nm/kg cm−1 1.6 ± 0.6 1.5 ± 0.7
Baseline MVC normalized to abdominal muscle thickness below umbilicus from US Nm cm−1 51.0 ± 22.0 48.5 ± 20.3
Time-to-task failure min 10.6 ± 5.5 12.4 ± 7.4
Rating of perceived exertion at task failure 0–10 scale 6.9 ± 2.0 6.0 ± 2.4
MVC at task failure % baseline MVC 70.6 ± 13.7% 69.6 ± 18.6%
MVC at 10 min recovery % baseline MVC 98.9 ± 23.7 90.5 ± 18.8
MVC at 20 min recovery % baseline MVC 102.2 ± 18.7 94.2 ± 26.3
  1. MVC maximal voluntary contraction, US ultrasound, DXA dual X-ray absorptiometry, min minutes
  2. No significant differences between sexes
