ABSTRACT
This study aimed to investigate the effects of an anterior superficial myofascial
chain strengthening program on maximum ball speed, myofascial elasticity, muscle
activation, and shank kinematics in young soccer players. A total of 32 licensed
soccer players, aged 13–14 years, were recruited and randomly assigned to either
an exercise group or a control group. Participants in the exercise group
underwent an 8-week anterior superficial myofascial chain strengthening program
consisting of three progressive phases. At baseline and after the 8-week
intervention, the maximum ball speed during the instep kick was measured using a
radar gun; muscle activation was assessed via surface electromyography; and
shank rotational velocity and acceleration were recorded using an inertial
measurement unit. Myofascial elasticity was evaluated using a myotonometer.
Compared to the control group, the exercise group demonstrated significant
improvements in the maximum ball speed, muscle activation, and myofascial
elasticity. However, no significant changes were observed in shank rotational
velocities or accelerations. Correlation analysis revealed that changes in
maximum ball speed were significantly associated with alterations in muscle
activation and myofascial elasticity. The ASMC strengthening program increases
the maximum ball velocity during the instep kick in young soccer players by
improving muscle activation and myofascial elasticity.
