  1. MT Muscle thickness, FL Fascicle length, PA Pennation angle
  2. Significance tested with Friedman’s test, followed by pairwise Friedman’s tests where p < 0.05. Stastically significant p-values have been marked with *. Muscle thickness and pennation angle of the vastus lateralis muscle significantly decreased over both 5 and 10 days
