Manipulating task constraints in children’s badminton: How equipment and rule modifications shape skill acquisition and game performance

Abstract

BACKGROUND: The concepts of body-scaling, specifically pi ratios, have been developed to establish systematic guidelines for adapting junior sports.

AIM: To investigate the impact of modifying court size and game rules using a body-scaling approach on badminton performance during match-play among children.

METHODS: In a seven-week crossover training program, thirty boys (mean age = 13.17 ± 0.83 years) were exposed to both standard court and rules (SCR) and modified court and rules (MCR) conditions. Three evaluation points – the pre-test, the intermediate test, and the post-test – were used to measure performance indicators such as winning strokes, successful strokes, and unforced errors.

RESULTS: Successful strokes (F(2,58) = 10.412, p <.05, η² =.488), winning strokes (F(2,58) = 12.865, p < .001, η2 = .556), and unforced errors (F(2, 8) = 8.231, p < .05, η2 = .487) all showed significant interaction effects, according to a two-way repeated measures ANOVA. Under the MCR condition, the following main effects also improved more: winning strokes (F(1,29) = 42.947, p < .005, η2 = .748), successful strokes (F(1,29) = 71.583, p < .001, η2 = .902), and less unforced errors (F(1,29) = 33.114, p < .001, η2 = .695).

INTERPRETATION: These findings imply that task constraints based on children's physical attributes greatly improve technical skills and overall game performance in badminton performance. The body-scaling strategy provides a practical way to promote more effective performance and stroke execution in junior badminton by increasing stroke effectiveness and reducing unforced errors during match play.
