Reliability and Validity of the Inline Skating Skill Test.

Area of Science:

• Sports Science
• Biomechanics
• Skill Assessment

Background:

• Inline skating is a popular recreational and competitive activity.
• Objective and reliable methods are needed to assess inline skating skills.
• Existing skill tests may lack comprehensive validation for diverse skater levels.

Purpose of the Study:

• To evaluate the reliability and validity of a novel inline skating skill test.
• To determine the test's ability to differentiate between competitive and recreational skaters.
• To assess the correlation between self-rated skill and objective performance measures.

Main Methods:

• Forty-two skaters (competitive and recreational levels) performed the skill test four times.
• Performance time was measured across a course combining various skating techniques.
• Intra-class correlation coefficients (ICC) and within-individual variation were calculated for reliability; performance differences and self-ratings were used for validity.

Main Results:

• The test demonstrated high inter-session reliability (ICC = 0.97–0.99) and low within-individual variation (1.6%–2.7%).
• Competitive skaters performed significantly faster (24.4–26.4% less time) than recreational skaters (p < 0.01).
• A moderate correlation (ρ = 0.80–0.82) was found between self-rated skill and actual performance times (p < 0.01).

Conclusions:

• The proposed inline skating skill test is a reliable and valid tool for amateur competitive and recreational skaters.
• The test effectively distinguishes performance levels between competitive and recreational skaters.
• Further research is recommended to assess reproducibility in elite populations.
