Clinical Context

We think this might be relevant to the clinical guidance for Session RPE (Internal Load).

Session RPE (Internal Load)

Internal Training Load (sRPE)

300

Arbitrary Units (AU)

Session Duration (min)

Perceived Exertion (0–10)

Foster Method: Total Load = Duration × RPE. Use as the daily "Acute" load for calculating ACWR (Acute:Chronic Workload Ratio). Higher RPE sessions should be shorter to maintain optimal load management.

Guidelines & Evidence

Verified

Last Review: 2026

When to Use

Quantifying internal training load when heart rate monitors and GPS are unavailable or impractical

Daily training load tracking for ACWR calculation and injury risk monitoring

Team sport environments where individual monitoring of 20–40 athletes simultaneously is required

Cross-sport load comparison — sRPE provides a common currency across running, swimming, cycling, and resistance training

Detecting overreaching: rising sRPE at constant external load signals early functional overreaching

Method

Record Borg CR-10 RPE 30 minutes after session end (not immediately — acute distress inflates RPE). Multiply by session duration in minutes. Example: RPE 7 × 90 minutes = 630 AU. This 30-minute delay removes the "end-spurt" bias and produces a whole-session average intensity that correlates with HR-based TRIMP (r = 0.80–0.86).
