Exploring Segmental Speed as a Measure of Motor Competence.

Background: Motor competence (MC) tests typically assess various aspects of movement, often focusing on fundamental motor skills (FMS), either from a product- or process-oriented perspective. Purpose: This study aimed to examine the relationship between product outcomes and segmental speed in FMS, expanding the methodological options for investigating MC. Study sample: Participants were 50 undergraduate students (25 men and 25 women) aged 21.2 ± 2.0 years. Research Design: performance was assessed using maximum ball speed for throwing and kicking, and jump distance for standing long jump. Data collection: Segmental speed was determined using motion analysis at key moments: ball release for throwing, ball contact for kicking, and take-off for jumping. Results: Significant correlations were found between product and segmental speed across all FMS (r ≥ .70, p < .001), both in general and by sex, despite males displaying superior performance and segmental speeds. Conclusions: These findings highlight that segmental speed reflects differences in MC and can serve as an alternative or complementary approach to product measures. However, the determination coefficients revealed varying degrees of influence from additional factors, suggesting that variable selection should align with the study's focus-whether emphasizing movement processes or performance outcomes. Our results broaden the methodological toolbox for assessing MC and provide a foundation for future research, including the investigation of MC in other populations and the examination of how segmental speed relates to movement patterns.
