[Purpose] To examine electromyographic (EMG) activity change during dynamic contraction of the quadriceps with skin cold stimulation (SCS) over the vastus lateralis (VL) and L4 dermatome area on the medial side of the lower leg. [Subjects and Methods] Seventeen healthy male volunteers participated. Dynamic knee extension was performed at 15% maximum voluntary contraction (MVC). SCS is a method used to cool the skin to 25 °C using a gel-cooling pad. The SCS method has no effect on the muscle below the cooled skin. Subjects performed dynamic knee extension under 4 randomly selected conditions: (1) SCS of skin over the VL (SCS<sub>VL</sub>), (2)without SCS of skin over the VL (non-SCS<sub>VL</sub>), (3) SCS of L4 dermatome area on the medial side of the lower leg (SCS<sub>L4</sub>), and (4) without SCS of L4 dermatome area on the medial side of the lower leg (non-SCS<sub>L4</sub>). Surface EMG from the rectus femoris (RF), VL, and vastus medialis (VM) were recorded using miniature electrodes. [Results] The root mean square of the EMG (rmsEMG) of the VL with SCS was significantly greater than activation without SCS, but was decreased by SCS<sub>L4</sub>. However, the activity of RF and VM did not change in any condition. [Conclusion] Our results suggest that the influence of cutaneous input can demonstrably modulate muscle activation.<br>
