about a joint provide a possibility to estimate which muscles generate the actual movement. Electromyogram (EMG) recordings can provide information about the temporal
activity of the muscles. Although EMG has been recorded in the m. iliopsoas during very slow moveandments (6), EMG recordings of m. iliopsoas have to our knowledge never been obtained during kicking although this muscle is believed to contribute significantly
to the relatively large net hip flexor torque during kicking (2, 7). Accordingly, the purpose of the present study was to elaborate a method to record intramuscular EMG
from the iliopsoas muscle and to relate the activity to the kinetics during the soccer place kick
