A field-test battery for elite, young soccer players

Area of Science:

• Sports Science
• Human Movement Science
• Talent Identification

Background:

• Physical performance testing is crucial for talent identification and athlete development in soccer.
• Elite young soccer players require valid and reliable assessment tools to monitor progress.

Purpose of the Study:

• To examine the validity and reliability of a battery of field-based performance tests for elite young soccer players.
• To assess the importance of performance testing from the perspective of coaches, fitness professionals, and players.

Main Methods:

• A battery of field tests including heart rate response, vertical jump, sprints (10m, 20m), and agility was administered twice to 80 elite young soccer players (ages 8.9-19.1).
• Questionnaires were used to gather opinions from 170 coaches, 172 fitness professionals, and 101 players on the importance of performance testing.
• Statistical analysis included systematic bias ratio and random error components of 95% ratio limits of agreement.

Main Results:

• Physical performance testing was deemed important by 97% of coaches, 94% of fitness professionals, and 83% of players.
• The field-test battery demonstrated good reliability and validity, with most tests distinguishing between ability and age groups (p<0.05).
• Heart rate recovery from the Multi-stage fitness test was the only test that did not significantly differentiate between groups.

Conclusions:

• The validated field-test battery is a reliable and objective tool for assessing elite young soccer players.
• The findings support the use of these field tests for talent identification and performance monitoring in youth soccer.
• The high perceived importance of performance testing by stakeholders underscores the practical relevance of this assessment battery.
