Workload ratios that flag risk early
Strong calculates acute:chronic ratios automatically and flags an athlete climbing past their four-week average before it costs availability.
Training management
Your training load data, finally unified.
Stop exporting from one platform and pasting into another. Strong is the central command for your team's performance, integrating every metric into one clear, actionable view, so you decide on athlete readiness with complete confidence.
The problem
From fragmented data to decisive action
Your athletes use Polar, Whoop, Catapult, and more. Your data is everywhere. Strong connects it all. We bring total distance, high-speed distance, and accelerations into a single platform, giving you a complete picture of external load. This is the workload management tool built for the demands of elite sport, not a spreadsheet pieced together every Monday.
- Load in Polar, recovery in Whoop, GPS in Catapult, the squad picture nowhere
- Hours lost each week exporting and reconciling before any analysis begins
- Readiness calls made on a partial view of external load
The solution
Precision tools for peak performance
Go beyond raw numbers. Strong calculates acute:chronic workload ratios to flag injury risk before it costs availability, detects fatigue, and alerts on declining movement quality. Track every athlete against your periodisation plan so they are primed for competition, not burnout.
The signature ratio
Acute load against the chronic baseline
The acute:chronic workload ratio is the sports-science read every S&C coach trusts: this week's load measured against the rolling four-week baseline. Strong builds it around your fixture schedule and renders the sweet spot and the danger zone so the standout reads by shape and label, never by colour alone. When an athlete climbs out of range, the right staff hear about it before it becomes a non-contact injury.
Acute-to-chronic workload
This week's load against the rolling four-week baseline. The shaded band is where adapted athletes usually sit.
- Sweet spot 0.8 to 1.3
- Danger zone above 1.5
The session, in numbers
External load you can act on
Total distance, high-speed running, sprint distance, accelerations and decelerations. Each metric is scaled against its own typical session ceiling, so the four read against a common sense of how hard today was. The bar that runs past its ceiling is marked, so an overload reads at a glance and traces straight back to the work that produced it.

What you can track
The training-load record, in plain terms
- Acute:chronic workload ratio
- This week's load divided by the rolling four-week baseline, the early read on whether an athlete is ramping too fast.
- Total distance
- The volume of ground covered in a session, the floor of external load.
- High-speed running
- Distance covered above the high-speed threshold, where soft-tissue cost climbs.
- Sprint distance
- Distance at maximal effort, the sharpest and most fatiguing slice of a session.
- Accelerations and decelerations
- The count of hard speed changes, the efforts a distance figure alone hides.
- Periodisation compliance
- Actual output measured against the planned phase, so the programme matches reality, not intention.
What it does
Built for the demands of elite S&C
Fatigue and movement-quality alerts
Algorithms detect accumulating fatigue and surface declining movement quality, so a problem reaches the right staff while it is still small.
Periodisation that matches output
Track every athlete's actual work against your periodisation plan, so the squad arrives primed for competition rather than burned out.

Strong gives us unfiltered access and control over our performance data. The system is built on a foundation of sports science, which gives us the analytical power to validate our methods and communicate decisions clearly to the rest of the staff.
