%X The purpose of this study was to compare the fascicle length, angle pennation and mechanicalproperties of the biceps femoris long head (BFlh) in dominant and non-dominant limbs in previously injured anduninjured professional football players. Fifteen professional football players were recruited to participate in thisstudy. Seven players had suffered a BFlh injury during the previous season. Myotonometry mechanical propertieswere measured in the proximal, common tendon and distal BFlh using MyotonPRO, and angle pennation andfascicle length were also measured. We observed significantly higher distal BFlh frequency, stiffness, decrement,relaxation and creep than in the common tendon and proximal BFlh. The previously injured players showedsignificantly higher frequency and stiffness, and lower relaxation and creep in the dominant BFlh than did uninjuredplayers. There were no significant differences between the fascicle length and angle pennation in previouslyinjured and uninjured BFlh. Myotonometric measurement provides a quick and inexpensive way to check theproperties of the BFlh in professional football players. Professional football players with previous BFlh injuryshowed higher intrinsic tension and a poorer capacity to deform than did players with no injury to the BFlh.
