“…In contrast, we found that interlimb coupling was higher in trials ending uncomfortably both before and after peak velocity, making a biomechanical explanation of these diVerences unlikely. A more reasonable explanation for this diVerence in coupling strength is that comfortable ending trials are more experienced and that practice results in a freeing of the degrees of freedom of the action system that underlies interlimb coordination (Temprado et al 1997). …”

In this study we investigated the relative impact of planning and execution constraints on discrete bimanual task performance. In particular, in a bimanual CD-placement task, we compared people's preference to end movements comfortably with their preference to move symmetrically. In "Experiment 1" we examined the degree of interlimb coupling as participants repositioned two CDs in a CD rack by simultaneously moving their arms mirrorsymmetrically or asymmetrically into comfortable or uncomfortable end postures. Interlimb coupling was stronger when the arms moved symmetrically towards uncomfortable end postures. In "Experiment 2" participants were asked to realize speciWc end orientations of the CDs but they were free to choose an initial grip type and subsequent direction of forearm rotation. Surprisingly, the participants did not move their arms symmetrically but preferred to end in a comfortable posture with their right hand but not with their left hand. We conclude that in discrete bimanual task performance the tendency to end movements in a comfortable posture dominates over the tendency to synchronously activate homologous muscle pairs. The lateralized end-state comfort eVect suggests a hemispheric specialization for motor planning.

“…Anderson and Sidaway noted a proximodistal coordination of joints when participants kicked a stationary ball. Temprado, Della-Grasta, Farrell, and Laurent (1997) and Putnam (1991) also noted proximodistal coordination during the volleyball serve and the punting of a ball in American football and soccer. To our knowledge, no investigators have conducted research on the soccer kick with an approaching ball.…”

“…Identification of the principles governing such assembly processes poses a major challenge to human movement scientists. In addressing this problem, researchers have focused predominantly on the formation of task-specific synergies among body segments, joint angles and end-effectors (e.g., Arutyunyan et al 1968Arutyunyan et al , 1969Newell and Van Emmerik 1989;Temprado et al 1997;Zanone and Kelso 1992). Although coordination among effector components is a necessary requirement for achieving a certain task goal, it is usually not a sufficient one.…”

We examined the development of task-specific couplings among functional subsystems (i.e., ball circulation, respiration, and body sway) when learning to juggle a three-ball cascade, with a focus on learning-induced changes in the coupling between ball movements and respiration and the coupling between ball movements and body sway. Six novices practiced to juggle three balls in cascade fashion for one hour per day for twenty days. On specific days (7 in total), ball movements, center-of-pressure (CoP) trajectories and respiration traces were measured simultaneously. Discrete, time-continuous and spectral analyses revealed that the spatio-temporal variability of the juggling patterns decreased with practice and that the degree to which the task constraints were satisfied increased gradually. No conclusive evidence was found for ball movement-respiration coupling. In contrast, clear-cut evidence was found for the presence of 1:3 and 2:3 frequency locking between the vertical component of the ball trajectories and both the anterior-posterior and the medio-lateral components of the CoP. Incidence and expression of these mode locks varied across individuals and altered in the course of learning. Gradual changes in locking strength, appearances and disappearances of mode locks, as well as abrupt transitions between coupled states were observed. These results indicate that dissimilar learning dynamics may arise in the functional embedding of subsystems into a task-specific organization and that motor equivalence is an inherent property of such emerging task-specific organizations.
