摘要

Background: The Pediatric Comprehensive High-Level Activity Mobility Predictor (Pedi-CHAMP?) is a 4-part agility test aimed to assess functional performance in children with and without sports medicine injuries or orthopedic conditions. The Pedi-CHAMP? assesses bilateral single limb balance, lateral agility, directional changes, and acceleration/deceleration. Hypothesis/Purpose: To determine if the Pedi-CHAMP component (Single-Limb-Stance [SLS], modified Edgren Side Step [mESS], L-Test, Illinois Agility Test [IAT]) and composite scores are stratified based on age, sex, and sport-type/specialization in youth athletes. Methods: Youth athletes were recruited to complete the Pedi-CHAMP? either as an independent test or as part of larger battery of tests (Specialized Athlete Functional Evaluation [SAFE] Program). Completion times for each test component were converted to points using age-sex matched scoring algorithms. Each participant also answered questions to determine specialization in organized sports (defined as competition with a referee, umpire, etc.). Kruskal-Wallis was used to assess differences based on age groups (elementary [E, 5-9yrs], preteen [PT, 10-12yrs], early teen [ET, 13-15yrs], late teen/young adult [LT, 16-22yrs]), with Mann-Whitney U pairwise post-hoc comparisons (α&0.05). Independent Mann-Whitney U tests were used to assess differences based on sex, sport type (low vs high impact) and specialization (single vs multi-sport) within each age group. Results: A total of 251 youth athletes (134 females, age 13.7±3.3yrs; BMI 20.9±5.9) completed Pedi-CHAMP? testing. Significant differences were seen with the Pedi-CHAMP? component and composite scores between all ages ( p &0.001, Table 1), however, there were no differences between ET and LT groups for the SLS or mESS. When assessing age and sex, elementary-aged girls demonstrated improved SLS balance ( p =0.017), and mESS scores were higher in preteen boys compared to girls ( p =0.022). However, all 3 agility components (mESS, L-Test, IAT) and the Pedi-CHAMP? composite scores were significantly higher in boys compared to girls for the ET and LT groups. When accounting for age, there were no differences in single-sport vs. multi-sport athletes. ET and LT low-impact athletes scored lower on the L-test compared to high-impact athletes. Conclusion: The Pedi-CHAMP? was able to detect differences based on age, sex and sport impact-type (low- vs. high-impact). Performance improves with age for the L-Test and IAT, however, no differences in SLS and mESS were seen between younger and older teens which may indicate a ceiling effect for these two components. Further research should focus on correlating the Pedi-CHAMP? to other performance measures in youth athletes.
