Fig 8. Forest plot effect sizes Nordic Hamstring Exercise (NHE) on biceps femoris fascicle length based on the ultrasound assessment and extrapolation methods.
The overall effect size of the NHE on increasing biceps femoris FL was large (g = 1.09 [0.16, 2.01], I2 = 79%). NHE has a small effect size on increasing the biceps femoris FL based on the MLE method (g =, 0.23 [-1.02, 1.47], I2 = 69%), has a small effect size on increasing biceps femoris FL based on the panoramic ultrasound scanning (g = 0.38 [-0.50, 1.27]), and has a large effect on increasing biceps femoris FL based on the equation methods (g = 1.98 [0.52, 3.44], I2 = 79%) (created via RevMan 5.4.1).
