Table 1 Summarized results of normalized EMG values of VMO, VLL and VLO muscles during MVIC knee extension at 90° of flexion and MVIC hip abduction at 0° and 30° of abduction (N = 21) The results are shown as a percentage of MVIC at 50° of knee flexion in a seated position

From: The effect of hip abduction on the EMG activity of vastus medialis obliquus, vastus lateralis longus and vastus lateralis obliquus in healthy subjects

Test procedure VMO (%) VLL (%) VLO (%)
Hip abduction at 30°    
Male 53.70 88.31 75.70
Female 96.07 119.61 103.98
Hip abduction at 0°    
Male 69.05 110.62 90.25
female 87.09 100.13 92.30
MIVC at 90° of knee flexion    
Male 144.91 c 115.31 146.72 d
female 165.97 b 141.30 162.61 a

  1. Letters demonstrate higher EMG activity of the same muscle in which there were statistically significantly differences between the three exercises
  2. a p = 0,02196 High EMG activity MVIC knee extension at 90° of flexion vs MVIC hip abduction at 0° of abduction
  3. b p = 0,008 High EMG activity MVIC knee extension at 90° of flexion vs MVIC hip abduction at 0° and 30° of abduction
  4. c p = 0,000055 High EMG activity MVIC knee extension at 90° of flexion vs MVIC hip abduction at 0° and 30° of abduction
  5. d p = 0,000761 High EMG activity MVIC knee extension at 90° of flexion vs MVIC hip abduction at 0° and 30° of abduction
