To get the most out of Soma, it’s essential to understand the comprehensive data it provides. This article simplifies key metrics used to evaluate an athlete’s performance, such as reaction time, speed, variation, RCS (Rate Correct Score), accuracy, BPM, rMSSD, and SDNN. Each metric is explained in clear terms, covering its significance, indicators of good performance, and how to interpret both mean data and minute-by-minute changes.
At Soma, We Go Beyond the Mean
Why Averages Aren’t Enough
The chart on the left shows a single average value, which might appear consistent and “good” at first glance. However, the chart on the right reveals the variability and trends over time captured through Minute-on-Minute (MoM) monitoring. This difference underscores why MoM analysis is critical for identifying patterns, strengths, and areas for improvement that averages fail to capture.
MoM monitoring captures real-time performance data at one-minute intervals during cognitive tasks. This granular approach uncovers patterns, highlights strengths and weaknesses, and provides actionable insights to fine-tune training for optimal results.
What MoM Monitoring Reveals
Breaking Points
Identify when performance starts to decline due to fatigue or overload.
Adaptation
Track whether athletes sustain or improve their performance over time.
Trade-Offs
Understand how athletes balance competing demands, such as speed versus accuracy.
Context Matters: Combining MoM and Mean Data
When analyzing MoM data alongside mean data, it’s crucial to understand the context behind the numbers to make informed decisions.
Heavy Season
During intense competition schedules, cognitive training loads should be lighter to maintain peak performance. Expect minimal fluctuations in MoM data during this period, as the focus is on sustaining performance and optimizing for game day. Significant fluctuations may indicate an overly demanding training load that requires adjustment.
Off-Season or Pre-Season
These phases are ideal for pushing training intensity and applying cognitive stress to drive adaptation and improvement. Greater fluctuations in MoM data are expected, reflecting the increased demands on the athlete.
With a clear understanding of the broader context provided by Minute-on-Minute monitoring, we can now dive deeper into the specifics, starting with one of the most critical metrics: reaction time.
Reaction Time
Why Reaction Time is Important
Measures response speed.
Why Reaction Time Isn't Always Reliable
Outliers distort average reaction time data.
Highly variable.
How to Interpret Reaction Time Data
Low reaction time alone isn't sufficient due to variability.
Combine with other metrics for true performance changes.
Why Reaction Time Matters
Provides insights into an athlete's response speed.
How to Interpret Reaction Time Data
When interpreting reaction time data, it’s easy to assume that faster is always better. However, relying on this metric alone can be misleading due to its high variability, making it unreliable as a sole indicator of improvement.
For a more accurate picture, consistency in performance is key. This is where the Coefficient of Variation (CV) plays a critical role. By comparing the standard deviation to the average reaction time, CV highlights the reliability of the data, which we’ll explore in more detail in the variation section.
While a low reaction time is desirable, it must be evaluated alongside other metrics to ensure that performance improvements are genuine and not just due to natural fluctuations or chance. Reaction time alone isn’t enough; a comprehensive analysis requires a combination of multiple metrics, which we will explore in the following sections.
For now, remember that while a lower reaction time is better, it needs confirmation with additional data.
Minute-on-Minute Reaction Time
Minute-by-minute reaction time data helps in understanding an athlete’s cognitive performance trends, providing insights into their adaptability, consistency, and overall cognitive state. This granular view goes beyond average reaction times and reveals performance fluctuations over time. Below are key insights when analyzing minute-by-minute data over the duration of a task.
These insights can help you in optimizing the cognitive training plan for your athlete.
Increase in Reaction Time:
May signal growing fatigue or a shift towards prioritizing accuracy over speed.
If reaction time slows, it may indicate mental fatigue or a focus on accuracy over speed. Monitor and see if reaction times decrease as the athlete adapts. Instruct the athlete to aim for both speed and accuracy.
Decrease in Reaction Time:
Task may be too easy or the athlete is becoming more adept.
A faster reaction time over the task's duration could mean the task is too easy or the athlete is adapting. Some athletes may start slow and gain speed, showing their response behavior.
Fluctuations in Reaction Time:
Inconsistency or potential issues with focus or task variability.
Small fluctuations are normal, but large ones indicate inconsistency. This could mean the task is too demanding or the athlete lacks consistency. If pushing capacity is the goal, monitor if fluctuations reduce over time.
Stable Reaction Time:
The workload has become routine or the athlete has fully adapted.
Steady reaction times indicate that the athlete has adjusted to the cognitive demands. To enhance performance further, consider modifying the training plan. Maintaining neural efficiency is acceptable if stable reaction times align with the current training plan's goals. The approach should depend on what the training plan aims to achieve.
Speed
Why Speed is Important

Lower speed = slower responses or outliers.
Evaluate alongside accuracy and variation.
Why Speed Matters
Provides insight into true performance capabilities.
Identifies areas for improvement.
Ensures training adjustments lead to genuine enhancements.
Offers a comprehensive understanding of cognitive abilities.
How to Interpret Speed Data
Interpreting speed data involves understanding its inverse relationship with reaction time. While higher speed generally indicates better performance, it’s essential to consider potential outliers and variability. Speed must be evaluated alongside other metrics such as accuracy and variation to confirm genuine improvements and avoid misinterpretations due to natural fluctuations or anomalies. This comprehensive approach ensures a more accurate and reliable assessment of an athlete's cognitive performance.
Now, let’s go over an example to highlight the significance of speed in cognitive performance data.
Consider the following reaction time improvements:
Initial Reaction Time: 536 ms
Retested Reaction Time: 358 ms
Improvement: 33.21%
While this improvement in reaction time is substantial, examining the speed data gives us even more insight into the athlete’s performance:
Initial Speed: 2.06 ms
Retested Speed: 2.87 ms
Improvement: 39.32%
This demonstrates that relying on a single measure is insufficient. More data is needed to determine whether changes are due to natural fluctuations or luck. Additionally, there is a 6.11% difference between reaction time and speed improvements, which indicates the presence of outliers within the data. The next step is to confirm variation to understand the underlying factors influencing these results.
Minute-on-Minute Speed
Analyzing minute-by-minute speed data provides deep insights into an athlete's cognitive performance trends, revealing fluctuations and adaptations over time. This detailed view helps in fine-tuning training plans to optimize performance.
Decreased Speed:
Fatigue or prioritizing accuracy.
Slower speed may suggest the athlete is focusing on improving accuracy. Striking a balance between speed and precision is crucial.
Increased Speed:
Improved processing and decision-making.
While faster speeds signal better performance, ensure it doesn't compromise accuracy or consistency. True enhancement is achieved when speed and reliability are coupled.
Fluctuating Speed:
Inconsistent performance.
Small fluctuations are normal, but large ones indicate inconsistency and may highlight significant outliers in the data. This can suggest the athlete is overloaded, causing extreme variations in responses.
Stable Speed:
Routine workload or adaptation.
Consistent speed indicates the athlete has adapted to the workload. To challenge the athlete further, adjust the training plan. If the aim is to maintain efficiency, stable speed is optimal.
Variation
Why Variation is Important
Measures response consistency.
Identifies stable or erratic performance.
How to Interpret Variation Data
Lower variation = consistent performance.
Higher variation = potential fatigue or inconsistencies.
Adaptation Process
High initial variation is normal.
Reduced variation over time indicates successful adaptation.
Why Variation Matters
Offers insights into genuine progress vs. natural fluctuations.
Fine-tunes training plans for sustainable improvements.
Essential for comprehensive performance assessment.
How to Interpret Variation Data
Interpreting variation data is crucial for assessing an athlete’s performance consistency over time. Here’s why it matters and how to make sense of it.
Understanding Variation
Variation measures the degree of fluctuation in an athlete's responses, indicating whether performance is stable or erratic. A lower variation suggests that the athlete's performance is consistent and reliable. Conversely, consistently high variation indicates poor response consistency, which may be a sign of increasing fatigue, overly intense tasks, or tasks that are too long in duration, preventing the athlete from sustaining optimal performance. If an athlete's variation shows no improvement over the course of a training plan, it’s crucial to reassess and adjust the training strategy.
The Adaptation Process
At the start of a training plan, it’s normal for variation in performance to be high as athletes adapt and become more neurally efficient. Over time, this variation should decrease, signaling successful adaptation. Think of it like lifting weights: at first, the weights feel heavy, and each rep is tough, but as you get stronger, the weights feel lighter, and the reps become smoother. Similarly, reduced variation in cognitive performance indicates the athlete is adapting to the training.
To illustrate this, let’s expand our example by including variation data.
Reaction Time:
Initial: 536 ms
Retested: 358 ms
Improvement: 33.21%
Speed:
Initial: 2.06
Retested: 2.87
Improvement: 39.32%
Variation:
Initial Variation: 45%
Retested Variation: 21%
Improvement: 24%
At first glance, a reaction time of 536 ms and a speed of 2.06 may seem impressive. However, when we factor in the initial variation of 45%, it becomes clear that the performance was inconsistent. After retesting, the variation dropped to 21%, indicating much more consistent performance.
Without analyzing variation, it’s difficult to tell if changes are genuine or merely random fluctuations. Variation links all aspects of performance, ensuring that improvements are real and not just the result of outliers.
Why Variation Matters
Variation data provides valuable insights into an athlete's performance. It helps determine whether improvements are due to genuine progress or just natural fluctuations. By consistently monitoring variation alongside other performance metrics like reaction time, speed and accuracy, you can make more informed decisions about an athlete's training regimen.
In summary, while reduced reaction times are important, understanding variation is essential for a comprehensive assessment of performance. It’s not just about getting faster; it’s about getting consistently faster and more reliable. Use this data to fine-tune your training plans and ensure that your athletes are not only improving but doing so in a sustainable and dependable manner.

How to Interpret RCS
An increase in RCS usually means better speed and accuracy, showing the athlete is responding more effectively. However, if this increase comes with higher variability, it might indicate inconsistencies, suggesting the need for more focused training. A decrease in RCS could be due to a strategy to slow down for better accuracy or issues like fatigue and loss of focus, requiring a detailed analysis to optimize training and recovery. A steady RCS suggests either a routine workload or full adaptation, indicating the athlete has effectively met the challenge.
Practical Example
For instance:
Athlete A: Increased RCS from 1.2 to 1.8 correct responses per second, indicating significant improvement in both speed and accuracy.
Athlete B: Decreased RCS from 1.5 to 1.2 correct responses per second, suggesting potential fatigue or a strategic shift towards accuracy over speed.
This example underscores the necessity of evaluating RCS in conjunction with other performance metrics to gain a complete understanding of an athlete’s progress. By balancing speed and accuracy, RCS offers a detailed perspective on performance efficiency, making it a valuable tool for assessing and optimizing training outcomes.
