KOM Informatics: Overview Of The Statistically Significant Correlations Between Workload And Performance 2022-2023
By David Brown
The KOMInformatics.com SysAdmin has the ability to run a Training Effectiveness Report for a given time frame, workload window, and offset for each eligible user.
The report extracts statistically significant relationships between performance and workload using PR watts on the performance
side against kilojoules of work on the workload side. For background
info on the report and these concepts see the first article in this series KOM Informatics: Raising 20 Minute Power Over 4 Weeks: What Actually Worked.
Prior articles in this series have only looked at data in the 20 minute to 1 hour PR time box, since increasing 20 minute power is a major focus for many competitive cyclists. But there are 16 other PR time boxes employed by the system in the Training Effectiveness report. This article looks at Training Effectiveness data compiled from all of the PR time boxes.
Training Effectiveness Report Results (2022-2023)
As of 8/7/2024, The admin controlled Training Effectiveness report has run 9 times reporting on 6 month time frames (Jan-June, Jul-Dec) for 2022 and 2023. Five of those times the report used 28 days for the workload window, 0 days for the offset and 5 for the number of PRs. 28 days was thought to be a reasonable amount of time for most interventions to start showing some results. The data from the last time the 28 day window was run (Jan-June 2024) is not included in this analysis which is limited to 2022-2023.
Sort Order
You can change the sort order of the tables below by clicking on a column header. Clicking on the same column header twice changes the direction of the sort.
Column Explanations
- User Percentage A number like 0.34 should be read as 34%. The scope is the entire 2-year period, and refers to users achieving at least one successful intervention involving a Workload or Time Bucket within the 2 year time frame.
- Watts Gain refers to the average difference between the best and 5th best PR within the scope of a single 6 month time frame.
- Average R Refers to the strength of the correlation within a single 6 month time frame. 1 is a perfect correlation
- Average # Of Interventions Looks at the average number of successful interventions for an workload/individual user within the scope of a single 6 month time frame.
- Max # Of Interventions Looks at the maximum number of successful interventions for an workload/individual user within the scope of a single 6 month time frame.

Discussion
- Looking at the Workload Prevalence for the 28-day workload window, there's something good to be said about almost every type of workload. Sprint intervals (Z6,Z7) had the highest user percentage (0.34, 0.32). NI (Non-Interval) claimed the biggest watts gain (59). Aerobic intervals (Z4, Z5) had the highest average number of successful interventions (1.95, 1.92)
- Looking at the Workload Prevalence for the 14-day workload window, Z6 stands out with both the highest user percentage (0.44) and watts gain (73).
- Looking at Workload Prevalence for both 14 and 28 day workload windows, many successful interventions were associated with multiple PR timeboxes. The max for the 28 day window was Z4 (8). For the 14 day window it was NI (6).
- Looking at Time Bucket Prevalence for both workload windows, 8:01-20:00 and 20:01-1 hour are both near the bottom of the list for watts gain. This speaks to the relative difficulty of raising 20 minute power.
- Looking at Time Bucket Prevalence for both workload windows, sprint durations are at the top of the list for watts gain. It appears relatively easier to raise sprint power as opposed to aerobic power, at least in terms of absolute watts.
- Looking at Time Bucket/Workload Prevalence for both workload windows at sprint durations, it doesn't seem like any clear patterns were established. Some of the interventions seemed to respect the specificity principle. For instance, for the 28 day window 21-30 time box Z6 and Z7 intervals were the 2 most popular modalities, and both registered solid watts gains (93 and 104 respectively). Other results did not appear to respect the specificity principle closely. The 28 day window 6-10 intervention ranks the Non-Interval (NI) modality the highest in terms of User Percentage (8%) and Watts Gain (136). TBF, NI could contain a fair amount of sprint work at sub interval durations. The same intervention ranks Z4 as the #2 modality in terms of User Percentage (6%), with a solid watts gain (114) only 8 watts out of second place. The 14 day window 21-30 intervention ranks Z4 highest in terms of User Percentage (15%). In this article1 reseachers found support for the idea that training longer durations can provide improved sprint performance for some.
- Looking at Time Bucket/Workload Prevalence for both workload windows at mid durations (3:01-5:00, 5:01-8:00, 8:01-20) no clear pattern is established. Z5 and Z4 intervals are better represented at the longer end of the duration range.
It's not clear from these results why certain interventions worked for certain users. Analyzing these results against the backdrop of the other training the users did might prove interesting, and help to answer these questions. Relating these results to rider phenotype might be another approach which could provide some explanations.
