, height = 448 pixels, slice thickness = 5 mm, slice increment = 5 mm, and number of slices = 162. Data were transferred in DICOM format (.DCM file). For both legs, the triceps surae, tibialis anterior, quadriceps, and other thigh muscles (including knee flexor and adductor muscles, and sartorius) were

intermittent running protocols to simulate the demands of soccer match-play 6 have failed to replicate the velocity profile and frequency of speed change observed during match-play. Kicking is often cited in relation to the high incidence of muscle strains in the thigh. 7 , 8 Quadriceps muscle strains

the lateral left thigh (LThigh) and base of the sacrum (S1) were used for analyses. A force plate (BP400600 NC; AMTI, Watertown, MA) was mounted on the seat to capture surface reaction forces under the thighs and buttocks, sampled at 200 Hz, in order to identify sit-to-stand-to-sit events.
