The present study investigated whether or not four weeks of supervised slackline training (SLT) performed on nylon webbing improves postural stability. Twenty-four healthy adults participated in the study and were assigned to either SLT (n 012) or a control (CON) group (n012). The SLT group completed a four week training program, while the CON group received no training. Centre of gravity (COG) and joint angles (ankle, knee and hip) were calculated using whole body three-dimensional (3D)

After SLT, a significant interaction was found for the SS condition in anteriorposterior COG mean velocity, whereas no changes were observed in the medio-lateral direction or in joint kinematics. In the PS condition, the medio-lateral COG mean velocity, frontal angular range of motion in the knee and hip joint, sagittal angular mean velocity in the knee joint, as well as frontal angular mean velocity in the hip joint were reduced in the SLT group only (all P B0.05). No significant training effects were detected in the ankle joint kinematics in either group from pre to post test. Our findings demonstrate that four weeks of supervised SLT improves postural stability in single leg stance on a stable surface and/or during compensation of perturbations.
