Background: Squats are well-known for their effectiveness in strengthening the quadriceps femoris muscle. Flexibility and stability of the ankle joint are critical factors in performing squats correctly. Ankle instability can lead to injuries owing to compensatory actions. The role of the soleus muscle in maintaining ankle balance is crucial to minimize the risk of injury. Moreover, squats on unstable surfaces have gained attention for their potential to enhance balance and stability, which in turn helps prevent injuries. Therefore, this study aims to investigate the correlation between the soleus and quadriceps femoris muscles during squat exercises on various support surfaces.
Design: Simple regression analysis Methods: Participants performed three different types of squats. Prior to commencing the exercises, we conducted electromyography (EMG) measurements to assess the activity of both the soleus and quadriceps femoris muscles. The order of the exercise execution was randomized. The squats were performed in a Full Squat format, and a one-minute rest was provided between each exercise type.
Results: Our analysis of the results revealed significant differences in the activation levels of the soleus and quadriceps femoris across different squat types (p<.05). The regression analysis revealed an inverse relationship between the activity levels of the soleus and quadriceps femoris. Specifically, the quadriceps femoris exhibited the highest activation during squats using a wedge, while its activation was lowest during squats using the TOGU. In contrast, the soleus muscle demonstrated its highest activation during squats using the TOGU.
Conclusion: Compared to traditional floor squats, the disparities in soleus and quadriceps femoris muscle activation observed during Wedge or TOGU squats can be attributed to the influence of ankle stability and balance. As the surface instability increased during squats, the soleus muscle's activity increased while the activation of the quadriceps femoris muscle decreased. These findings suggest that heightened soleus activation on unstable surfaces can significantly impact the activation of the quadriceps femoris muscle during squat exercises.
