“…In some studies where underarm throwing was performed with the aim to explore motor learning, the s 0 changed over the trials while α 0 remained constant (Kudo et al., 2000; Stimpel, 1933, pp. 105–138; Van Rossum & Bootsma, 1989).…”

“…In the case of the current paper, the choice of h 0 and s 0 as predictors of the performance changes, should be associated with the requirement of a high precision outcome. While s 0 was reported as a common parameter to modulate the performance in different throwing contexts (Dupuy et al., 2000; Kudo et al., 2000; Roberton & Konczak, 2001; Stimpel, 1933, pp. 105–138; Van Rossum & Bootsma, 1989), the h 0 was rarely found to be correlated with the performance.…”

“…In the few studies on learning to throw for accuracy, the analysis of the release parameters was limited to the initial phase of learning, with no exploration of stabilization and long‐term memory retention of the acquired performance (Kudo, Tsutsui, Ishikura, Ito, & Yamamoto, 2000; Stimpel, 1933, pp. 105–138; Van Rossum & Bootsma, 1989).…”

Learning precision ball throwing was mostly studied to explore the early rapid improvement of accuracy, with poor attention on possible adaptive processes occurring later when the rate of improvement is reduced. Here, we tried to demonstrate that the strategy to select angle, speed and height at ball release can be managed during the learning periods following the performance stabilization. To this aim, we used a multivariate linear model with angle, speed and height as predictors of changes in accuracy. Participants performed underarm throws of a tennis ball to hit a target on the floor, 3.42 m away. Two training sessions (S1, S2) and one retention test were executed. Performance accuracy increased over the S1 and stabilized during the S2, with a rate of changes along the throwing axis slower than along the orthogonal axis. However, both the axes contributed to the performance changes over the learning and consolidation time. A stable relationship between the accuracy and the release parameters was observed only during S2, with a good fraction of the performance variance explained by the combination of speed and height. All the variations were maintained during the retention test. Overall, accuracy improvements and reduction in throwing complexity at the ball release followed separate timing over the course of learning and consolidation.
