Integration with Polar Flow – Import of Average HR and TSS Calculation

It would be highly beneficial to enable integration with Polar Flow, allowing the import of average heart rate (HR)directly from recorded sessions into Lumin Strength/ARC. This would streamline the tracking of internal load by automatically calculating Training Stress Score (TSS) based on duration and average HR (or %HRmax/%HRR).

Ideally, this integration would:

• Pull average HR and duration from Polar Flow sessions

• Allow manual or automated assignment of intensity zones

• Enable calculation and visualization of TSS within the athlete’s load monitoring dashboard

Benefits:

• No need for manual HR data entry after each session

• Consistent internal load monitoring across platforms

• Enhanced precision for recovery and periodisation decisions

• Support for coaches using Polar across multiple teams or athletes

This feature would greatly improve workflow efficiency and data accuracy, especially for teams already using Polar as their primary HR monitoring solution.
