Skill acquisition interventions for the learning of sports-related skills: A scoping review of randomised controlled trials.

Background: Skill acquisition science is the study of how motor skills are acquired, developed and/or learned. There is substantive evidence for general motor skill acquisition in controlled laboratory settings yet the literature on the learning of sports-related skills is typically less conclusive.

Objectives: This scoping review aimed to summarise the current literature on skill acquisition intervention studies examining the learning of sports-related skills as part of a randomised controlled trial, by synthesizing and extracting the most relevant features.

Methods: Four electronic databases (PsychINFO, PubMed, SPORTDiscus and Web of Science) were searched for relevant studies. The sample characteristics of these studies were extracted, and summarised. Two systematic searches of the literature were conducted. In the first search, eighty-six studies were retained. A second search was conducted in July 2022 to include new studies and specifically focused on the inclusion of within-subject design studies, resulting in the inclusion of 35 additional studies. A third search was conducted in May 2023 to include new studies resulting in the inclusion of 10 additional studies.

Results: One hundred and thirty studies across 29 sports were included in the review. The vast majority of the studies in this scoping review (n = 104) examined the learning of a sport-related skill in participants with no experience. Twenty-eight percent of all retained studies (n = 35) considered only the learning of a golf skill, and all studies were practiced in a laboratory environment, examining closed motor skills (n = 130). The most common intervention categories reported were attention (n = 22), instruction and demonstration (n = 20), practice design (n = 20), and perceptual training (n = 19). Nearly half of all studies used an immediate retention test within 48 h of the cessation of practice (n = 63), and just over one quarter of studies (n = 34) reported incorporating some form of transfer test. Eighty-six percent (n = 112) reported positive findings.

Conclusions: The skewed focus on golf skills across a small number of skill acquisition interventions, the inconsistent use and reporting of performance measures, practice durations and measures of learning alongside the relatively small sample sizes consisting mostly of inexperienced learners and the skewed publication of positive findings should warrant caution. More empirical studies across a broader range of sports and with more consistent methodologies are needed to develop a robust pool of literature that can support academics and practitioners interested in which skill acquisition interventions could be used to influence the learning of sports-related skills.
