Benefits of Bandwidth Feedback in Learning a Complex Gymnastic Skill

Abstract

The aim of this study was to examine the effects of two different frequencies of feedback during the process of learning a complex gymnastic skill, the round-off salto backward tucked. Thirty male acrobats participated in the study. They were randomly assigned to two groups: B - bandwidth feedback (n=15) or C - 100% feedback (n=15). Group B was provided with error information regarding the key elements of movement techniques only (bandwidth feedback). Our research demonstrates the advantage of augmented feedback information related to errors in the key elements. Information about errors in the key elements during learning a complex gymnastic skill prevents the gymnast from becoming overwhelmed, which promotes better motor control. These results provide support for the generalisation of bandwidth feedback principles to a complex task. Our research shows that the guidance hypothesis can also be tested in practical settings for a complex movement task.

“…Although onecould argue that auditive modeling has contributed to present results, it was not an independent variable (since both groups received it). Beyond that,the bandwidth KR related to specific components of motor skill has lead to improvements in learning even withmodeling beingpresented (Sadowski et al, 2013). The interaction between modeling and bandwidth KR on motor learning can be investigated in future studies.…”

“…When one thinks about learning sequential motor skills, usinga specific bandwidth KR to each component of the motor skill can be a strategy to improve motor learning (Sadowski, Mastalerz, & Niznikowski, 2013). In this way, KR will be provided only for the component whose error is outside the bandwidth and not for all the components.…”

“…Thus, attention can be focusedonly on the components with higher errorand the harmful guidance properties of KR could be avoided. Although bandwidth KR can improve motor skill and prevent dependency, only one study was found that manipulating a specific bandwidth to each component of the motor skillduring practice (Sadowski et al, 2013). However, the authors did not address the possible negative consequences of bandwidth KR provided to each component of the motor skill.…”

Improving training for sensory augmentation using the science of expertise

“…Instead of providing feedback constantly, it can be provided on every nth trial or be faded, with the number of trials between presentations increasing as learning improves (Winstein & Schmidth, 1990). An alternative approach to providing intermittent feedback is to do so only when errors in performance exceed particular thresholds, called bandwidth feedback (Sherwood, 1988;Lee, 1990;Sadowski et al, 2013). Of course, for this approach to be effective, users must be informed about the bandwidth in advance.…”

Effect of Intervening Bandwidth Feedback on Motor Skill Learning in Self-Controlled Feedback Context

“…On the contrary, it provides qualitative external feedback information with correct indication). So the idea of not providing accurate feedback information for better motor performance is not quite right [3]. Therefore, it is necessary to further clarify the conflicting between these two viewpoints, and examine the additional benefits of self control and bandwidth feedback integration on motor learning in the self-controlled feedback context.…”
