Purpose: Volleyball is a complex sport with specific muscular demands that have a variety of explosive physical characteristics. The present study examines the effect of double-density insoles on the frequency of muscle activity in running and side cutting in volleyball players.
Methods: The current semi-experimental research was conducted on 30 teenage boys and girls in two groups of 15 people. The electrical activity of seven lower limb muscles was recorded in six running attempts and lateral sliding attempts using a biometric 8-channel electromyography device with 2-pole surface electrodes according to the SENIAM European protocol.
Results: The study revealed that double-density insoles significantly influenced the frequency of BF muscle activity during running (p= 0.045, d= 0.136). Notably, group differences significantly affected the frequency of TA muscle activity (p= 0.027, d= 0.163) and VM muscle activity (p= 0.006, d= 0.239) during lateral sliding. Additionally, the interaction between double-density insoles and group classification significantly influenced ST muscle activity during lateral sliding (p= 0.037, d= 0.146), with boys showing increased ST activity but not girls.
Conclusion: The use of double density insoles at the frequency of the biceps femoris muscle can prevent ACL damage and acute muscle injuries in running and in the frequency of the semitendinosus muscle in the movement of the sliding, it can be effective in preventing of genu varum injury in the in volleyball players.
