AnotationBalance forms the foundation of postural activities such as standing and walking, requiring a coordinated response from the neuromuscular system to information obtained from the proprioceptive, visual, and vestibular systems (Kerwin and Trewartha, 2001). "Slacklining" is a method used to enhance postural stability (Kodama et al., 2017). Beginners on a slackline experience uncontrolled oscillation of the line beneath their feet, attributed to the rapidly moving support base (Serrien et al., 2016). In this unstable and dynamically changing environment, coordination between joints and muscles plays a crucial role. Bernstein's theory defines coordination as the process of mastering redundant degrees of freedom involved in a specific movement, thereby turning joints, segments, and muscles into a controllable system (Bernstein, 1967). The fundamental question is how the controlling system restricts and selects possible solutions leading to an efficient solution of the movement task. These solutions are influenced by fundamental constraints arising from the individual, task, and environment, and their interactions (Newell, 1986). Understanding these constraints and interactions can provide new insights into the movement control and its regulation in skills where maintaining postural stability is a key factor. Most studies on slacklining have focused on the balance abilities and their development using slackline training (Donath et al., 2017). However, less attention has been given to fundamental skills (Kodama et al., 2017). Single leg stance is considered as fundamental skill in slacklining. Proper execution of this movement can be a significant in the process of acquiring and transferring other skills (Kodama et al., 2017). The purpose of this study is to investigate how the control and coordination of lower limb movements change from the perspective of dynamical systems theory during single leg stance in changing environment.
