- Abstract
All skilled actions are nested within a framework of postural control and so the ability to regulate posture paces the development of new skills and may mask the expression of certain patterns of coordination that cannot be revealed until specific body segments can be stabilized relative to each other or the whole body can be stabilized relative to the environment. Recently, we have explored the relationship between posture and movement using a kicking task in which various tests of one-legged balance are used to predict kicking velocity and accuracy. Two experiments were conducted in which the performance of various tests of one-legged balance on the nondominant leg was used to predict maximum kicking velocity (Experiment 1) or accuracy (Experiment 2) of the dominant leg. The balance tests included 1) maximal speed hopping forward, 2) maximal speed hopping sideways, 3) balance on a narrow beam, and 4) balance on a compliant surface with eyes closed. In Experiment 1 (N = 60 young adults), there was a significant correlation between kicking velocity and normalized hop length, r = 0.65; however, no other tasks were significantly correlated with kicking performance. In Experiment 2 (N = 40 young adults), there were significant correlations between kicking accuracy and normalized hop length sideways, r = -0.37, and normalized hop length forward, r = -0.32 (note that longer hops were associated with smaller errors relative to the center of the target). In addition, there was a significant correlation between kicking variability and balance on the narrow beam, r = 0.32. These preliminary findings are discussed in the context of a constraints perspective on the development of new skills. The limitations of the current approach are highlighted and suggestions are made for how the approach can be modified to provide deeper insights into the nature of the integration between posture and movement as skills such as kicking are developed.
