Whether you’re a club S&C coach or an outside performance consultant, testing dozens or even hundreds of youth athletes can feel overwhelming. In this quick guide, I’ll walk you through our approach to efficiently assess large groups in key areas like speed, agility, change of direction, and reaction time.
Everything you’ll read and see here is based on Sportreact’s recent testing at Zlatko Dalić's soccer camp in his hometown Livno. The event was a collaboration with NK Troglav and featured many legendary Croatian players. For those unfamiliar with Zlatko’s work, he was named the 2018 European Coach of the Year and has led the Croatian national team to silver and bronze medals in the 2018 and 2022 World Cups.
I am going to discuss:
BONUS: Stick around until the end to grab the report (with normative data) we put together after the testing session!
1. Prepare for the Soccer Speed and Change of Direction Test Session
Key questions you need to consider before staring the testing session:
What’s the main goal of the testing session?
How many athletes are participating?
How many coaches will be involved?
How much time do you have for the testing?
What equipment will you use to collect data?
Setting the Right Test Objectives and Goals
While the specific objectives of a testing session will vary based on its purpose, the core goal remains consistent: gather data, analyze it, and interpret the results to gain valuable performance insights about the athletes. Here are four common types of large-group testing we typically encounter in soccer:
Club Testing: Assessing athletes who are already part of the club/academy.
Tryouts Testing: Evaluating athletes during a recruitment process.
Camp Testing: Conducting tests as part of a soccer camp experience.
Research Testing: Gathering data for a specific research study or thesis.
Group testing type | Testing Goal | Periodization | Primary Report Users | Results Comparison | Reliability and Validity |
Club Testing | Gain performance and readiness insights across various teams | Multiple sessions (pre-season, in-season, post-season, etc.) | Athletic directors, sports scientists, soccer coaches, and S&C coaches | In-club comparison (across teams, ages, genders, locations, etc.) | Medium |
Tryouts Testing | Create a leaderboard to compare results across competitors | Single session | Athletic directors, sports scientists, soccer coaches, and S&C coaches | Comparisons across all tryout attendees | Medium |
Camp Testing | Share performance data with athletes and/or their parents | Single session | Parents, athletes, coaches | Comparisons across all camp attendees | Low |
Research Testing | Test the hypothesis based on the research thesis | Single or multiple sessions | Scientists, students | Across the sample in the research | High |
Use this short guide to set your own goals for the testing session. While there are various factors that differentiate these testing types, the process itself is quite similar, and the ultimate outcome is always a report with insights. How you use this report, and for what purpose, will vary from case to case.
Plan for athletes, coaches, and scheduling
Next, consider the size of the testing group, the number of coaches available, and the time you have. Here are some best practices:
Craft your roster of athletes
Having a list of athletes prepared before you step onto the field is crucial. It will save you a lot of time and help you conduct tests smoothly. I highly recommend using software tools to streamline this process and minimize errors.
Here are two important reasons to have a software-based list:
Track and Manage: With a list, you can easily track each athlete’s sequence and make adjustments if needed.
Real-Time Data Collection: Save and access results in real time, after the session is done, with a single click.
If you prefer going the manual route, using an Athlete Management System or a spreadsheet is definitely more efficient than jotting everything down on paper. Trust me, writing by hand can lead to a lot of problems.
Just a Heads-Up:
Expect drop-bys and missing athletes at almost every session.
Names lists might be incorrect occasionally.
Athletes often have the same first or last names, so using full names is a good idea.
Pro tip: Explore Sportreact as an effective system for organizing athletes and tracking their data:
Select Your Manpower
Make the Most of Your Time
Choose the right soccer testing equipment
The final item on your preparation checklist is selecting the right testing equipment. This choice largely depends on your testing goals. For speed, change of direction, or agility tests, you'll need a timing system that ensures reliability and validity.
Timing System: You basically have two options: timing gates or manual stopwatches. I strongly recommend using timing gates rather than manual stopwatches. Manual stopwatches are outdated, prone to human error, and not very precise. Without mentioning that they lack any kind of automation or data analytics.
Additionally, some newer timing devices use proximity sensors or other technologies, but they often lack validation and reliability in scientific research. Therefore, standard laser beam timing gates are a more reliable choice for accurate results and are considered the gold standard for measuring speed and agility.
Have Timing Gates Ready
Timing gates come in various formats based on your needs. For most tests, a three-gate system is sufficient. However, if you need to time multiple splits in a test (like a 60-meter dash with splits every 10 meters) or run tests simultaneously, consider having additional gates ready.
I recommend Sportreact timing gates because they’re super easy to set up and they help minimize errors. Unlike other systems that use separate emitters and receivers, Sportreact gates have both functions in each pod on each side. This makes setup a breeze and cuts down on alignment problems.
Pack your Accessories
Beyond these essentials, remember to consider the phase of soccer season, check weather conditions, ensure athletes are well-rested and energized, and confirm that you have enough space on the field.
Behind the Scenes: Our Prep for Zlatko Dalić’s Soccer Camp
So, how did we handle preparations for our recent camp? Since the camp focused mainly on technical and tactical aspects of the game, we used performance testing as a foundation to provide parents with a report on their kids' speed and change of direction abilities. Check out this video highlighting the Illinois Agility Drill.
Before the testing began, we gathered a list of all the kids attending the camp. We also had a few drop-ins just before the event, but our athlete management system made it easy to handle.
We had two coaches available but opted for just one testing station due to limited field space. A big thanks to Coach Ivica Vrgoc for helping us organize the session. We tested three age groups (U13, U14), rotating them on the field. Each age group was split into 3-5 smaller groups of 5-10 athletes.
The soccer coaches had set up several training stations (for ball control, dribbling, passing, etc.), and one of these was dedicated to our testing. The rotations between stations were smooth, and athletes arrived at our testing station already warmed up, which was a huge plus.
For timing, we used the Sportreact three-gate system to accurately time all the drills.
2. Choose the Right Speed and Change of Direction Tests
Depending on your goals, it's essential to choose the right speed, change of direction, or agility tests. In soccer, you might use various tests, from speed sprints and acceleration drills like the 10-meter to 40-yard dashes, to change of direction drills such as the T-test, 5-10-5 test, or the 3 cone test. From my experience, coaches at camps often select one sprint test and one change of direction test. Check out some common soccer tests and pick the ones that align with your goals.
Step Out of the Soccer Ordinary
If you want to step further with your testing capabilities, add a unique touch to your tests to gather more insightful data:
Test With and Without the Ball: Comparing these results can offer valuable insights. See the example of two different versions of T-test.
Include Standard Agility Drills: Change of direction tests can differ significantly from agility tests, as they introduce a cognitive element into the evaluation. Try tests like the Y-test or Stop'n'Go agility test, not just change of direction drills.
Create Custom Agility Tests: Elevate your testing with systems like Sportreact by adding cognitive stimuli such as colors, letters, numbers, or arrows. This approach measures speed, velocity, and reaction time while engaging athletes in dynamic, soccer-specific reactive agility tests with the ball. Check out these enhanced performance tests for next-level data.
Pros and Cons of Custom Tests
Pros:
Targeted Skills: Custom tests can evaluate specific soccer skills that standard change of direction tests might not capture.
Engaging Data: They provide more intriguing data, making your reports more insightful for all users.
Increased Engagement: Custom tests are often more engaging for athletes and can motivate them more than standard tests.
Cons:
Limited Normative Data: Standard tests offer more established data for normative analysis, which can be useful for comparison.
Setup Complexity: Custom tests can be more complex to set up and execute compared to standard tests.
What We Did at Dalić’s Camp
With over 50 kids and limited time, we opted for the 30-meter/yard sprints and the Illinois Agility Test.
The 30-meter (or 30 yard dash) allowed us to measure acceleration in the first 10 meters (yards) and evaluate speed and velocity in the remaining 20 meters (yards). The Illinois Agility Test was chosen for its comprehensive nature, effectively assessing change of direction through various movements like side steps, rotations, accelerations, and decelerations.
Our goal was to provide parents with easy-understandable performance data. The chosen tests were straightforward to explain and comprehend, and as parents observed the events, they found the tests engaging to watch.
Sprint Test (10-30 Meters/yards)
This test measures both starting and maximum straight-line speed. The 10-30 meter/yards sprint is crucial in soccer for assessing a player’s acceleration and speed over short distances, which are vital for situations like chasing a ball or breaking away from defenders. It shows how quickly a player can reach top speed, essential for both attacking and defensive plays.
Procedure: Start in a split-stance position 0.3 meters (one foot) behind the starting line (A). Accelerate to maximum speed and pass through the timing gates at 10 meters/yards (B) and 30 meters/yards (C) as quickly as possible. Perform the test three times, following the same protocol each time, and use the average of the three attempts for the final result.

3. Perform the Speed and Change of Direction Tests
With your test book ready and preparations complete, it’s time to hit the field. Here’s a handy checklist to guide you through the testing session:
BEFORE TESTING
Choose Your Spot: Find a location on the pitch that won’t interfere with other ongoing events.
Plan Rotations: If you have multiple stations, organize the rotation order to be fast and efficient.
Set Up in Advance: Prepare the tests on the field while athletes are warming up in a different area to save time.
Consider Sun Position: Plan for the movement of the sun during the session, especially if you’re recording video.
Use a Tripod: Set up a tripod for your tablet to track data hands-free.
Mark the Field: Use a measuring tape for accurate testing dimensions and cones to mark key points.
Match the Scheme: Ensure the testing setup matches the original test protocol.
Repeatability: For custom agility tests, create a repeatable scheme for consistency in future testing.
Align Timing Gates: Position and align the timing gates according to your test scheme.
Warm-Up: Ensure all athletes are properly warmed up and ready before starting the tests.

AFTER TESTING
Handling Timing Gates for Speed and Agility
As mentioned before, having a valid timing system is a must. To use timing gates effectively on the field, follow these best practices:
Accurate Placement: Position the gates at the start and finish lines of the sprint or drill. Ensure they’re aligned correctly to capture the exact moment a player crosses the line. For agility drills, place additional gates and reaction pods at key points.
Consistent Height: Set the gates at a consistent height, typically around hip level, to accurately detect the player’s body (usually the torso) as they pass through.
Use Multiple Gates: For complex drills involving various directions or segments, use extra gates to capture times at each segment. This helps break down and analyze specific parts of the performance.
Sync Equipment: Calibrate and test the timing gates before starting the session to avoid malfunctions during practice.
Provide Clear Instructions: Ensure players know exactly how to start, navigate through, and finish the drill for consistent and accurate timing.
Record Data: Utilize software to instantly record times, enabling quick feedback and thorough analysis later.
Just a Heads-Up:
For tests like 60-yard dashes, place a main (sometimes called master or base) timing gate in the middle of the distance to ensure better connectivity and accurate timing.
Check Communication Channels: Verify the communication protocols for your timing gates, as indoor and outdoor facilities might have different requirements.
Distance Between Gates: Position the gates about 1.5 to 2 meters/yards apart. If needed, experiment with greater distances to ensure reliable timing.
Monitor Environmental Factors: Be aware that direct sunlight or wind can affect timing accuracy. Check conditions before starting or use a system like Sportreact to minimize such issues.
Top Pro Tip - If you have a screen available, display a live leaderboard during the testing. It’s a great way for coaches, athletes, parents, and everyone watching to get real-time updates on performance. Plus, it really amps up the competitive spirit among the kids!

4. Create an Impactful Soccer Analytics Report
Alright, let’s get into the exciting part—what we’re really aiming for with this testing. The report is designed to deliver key insights into the performance metrics we've gathered. It not only provides a detailed comparison across the tested group but also includes normative data for standard tests. Our goal is to highlight the crucial takeaways so that everyone involved can better understand the results.
The structure of the report will vary depending on the type of group tested and the specific goals we set at the outset. In this article, I’ll focus on how to analyze and report data for soccer camps, though many principles apply across different testing scenarios. When working with large groups, especially over 100 athletes, it’s impractical to highlight individual results in the same way you might for one-on-one diagnostics. Instead, I recommend focusing on group-level analytics.
For speed and agility testing in soccer camps, concentrate on these key attributes:
Assessing Available Resources:
1. Timing System Metrics: Review the capabilities of your timing system to determine which speed and CoD metrics you can extract
2. Performance Parameters: Decide if you want to incorporate additional performance parameters alongside speed and agility results. Some useful metrics might include from testing Counter Movement Jumps (CMJ) or Velocity-Based Training Metrics
3. Additional Performance Metrics: Consider including other relevant metrics that can provide a fuller picture of an athlete’s capabilities. Reaction time is particularly useful for positions like goalkeepers, where quick decision-making is crucial. Tests could involve catching, diving, or other reaction-based drills.
Speed and agility Metrics to Include:
Comparative Analysis:
Progress Tracking:
Heat Maps and Visualizations:
Injury Risk Indicators:
Actionable Recommendations:
Reporting:
Just a Heads-Up:
Using a timing system with integrated data analytics software will save time and enhance reliability.
Keep the analysis straightforward and avoid technical jargon if the audience isn’t familiar with scientific concepts.
Clear charts and graphs can make the insights from the data easily understandable.
Include practical recommendations to ensure the report is actionable and useful.

BONUS - Sprint and CoD Report Example from Zlatko Dalić’s Camp
Here’s a brief overview of the results from our recent testing session. For the complete report example, click here.
Please note that the testing session report was created to give parents a more comprehensive view of their children's speed and change-of-direction abilities. The validity and reliability of the data presented are low, as the report's primary purpose is to provide peer comparison for the two age groups that attended the camp.
0-10-30 m/yd Sprint Test Results:
Age | 0m-10m [s] | 10m-30m [s] | 30 meter [s] | AVG Speed [km/h] 0-10m | AVG Speed [km/h] 10-30m | AVG Speed [km/h] 30m |
U13 | 2,122 | 3,038 | 5,159 | 17.04 | 23.83 | 21.03 |
U14 | 1,991 | 2,824 | 4,814 | 18.15 | 25.62 | 22.52 |
We tested two groups of athletes (U13 and U14), both male and female, totaling 48 athletes. A 0-10-30 meter sprint test was used to measure acceleration over 0-10 meters, speed from 10-20 meters, total time for 30 meters, and velocity for all three segments. The results were compared to normative data for sprint tests, which you can check out in the full report.
The average 30-meter sprint time for U13 athletes was 5.16 seconds, while for U14 athletes it was 4.82 seconds, which aligns with normative references. Several U14 athletes performed above their age group, while some U13 athletes were faster than their older peers. The results followed a normal distribution.
Illinois CoD Drill:
AGE | Illinois test time [s] |
U13 | 17,946 |
U14 | 17,120 |
We tested two groups of athletes (U13 and U14), both male and female, totaling 51 athletes. The Illinois CoD test was used to measure acceleration total time for the whole testing run. The results were compared to normative data for the same test.
The average test time for U13 athletes was 17.9 seconds, while for U14 athletes it was 17.1 seconds, which aligns with normative references. Compared to the sprint test, we can see that the differences between results are less pronounced, and there are no significant deviations in the results for the older age groups.
Our Report and Insights
For the camp, we opted for a straightforward report to give parents a clear understanding of how their children performed compared to their peers. I recommend using this basic format as a foundation for camp testing analytics, and suggest incorporating additional testing parameters tailored to your specific goals.
It’s important to note that the normative data is based on an estimated range for children and adolescents, meaning actual performance may vary depending on factors like fitness level, training, and environmental conditions.
Key takeaways for parents:
Compare your child's performance with peers in the same age group.
Compare your child's performance with peers in different age groups.
Analyze different splits to identify strengths and areas for improvement in sprinting.
Consider results based on different gender and positions, as performance may vary.
Use this information to better understand growth opportunities and develop a plan with the coach.

5. Get ready for your next testing session
This short guide provides a clear perspective on testing large groups of youth soccer athletes during camp. It is an interesting age group, as it is often referred to as the 'Golden Age' for developing motor skills. I hope it helps you structure your testing sessions effectively. I recommend experimenting with different testing setups to gain a better understanding of what works and what doesn’t. Starting with smaller groups can be beneficial, as it reduces the potential for errors and is less resource-intensive.
If you're interested in seeing similar testing sessions, check out our videos, such as the one from the Barca Academy where we conducted sprints with and without the ball, T-test, and Reactive Agility tests. You might also find our futsal testing with Futsal Dinamo useful, which includes drills like the 15x20 meters/yards test and 93639 change of direction test, both with and without the ball.
