“…The muscles of the shoulder girdle, flexors and rotators of the trunk, muscles that allow the arm to be raised above the horizontal axis of the shoulder, muscles that are used when moving the arms backward, and the muscles of the forearm and hand for gripping the ball together with the deep stabilizing muscles form the so-called muscle chain consisting of local and global stabilizers (Ammer et al, 2022, Bernacíková, 2010, Kostadinović et al, 2020, Srhoj et al, 2012. The mentioned muscles are one of the prerequisites for a movement pattern based on a kinetic chain, the components of which must work together to achieve proper movement, preventing muscle imbalance or injury (Lin et al, 2022, Manchado et al, 2017, Thurgood and Paternoster, 2014, Szczygieł et al 2018. One factor that influences the functioning of this kinetic chain during shooting is the muscles of the DSS of the spine.…”
