Show Notes

  1. Bring heart rate back into the conversation. Ibrahim and Martin revisit what makes it so powerful for understanding training load and adaptation.Their analysis across years of data suggests about 30 minutes above ~85–90% HRmax is enough to maintain aerobic fitness. The key takeaway? The concept matters more than the number. Use your own data to find your team’s threshold.
  2. Don’t just chase data, understand the dose and the response. A 10-minute increase in “time in zone” might boost aerobic capacity by 1–2%, but it also adds fatigue. Context is everything. For a player recovering from injury, low-intensity, longer-duration sessions may help rebuild mitochondrial size, while heat exposure or upper-body ergometers can sustain internal load when lower-limb work isn’t possible. The smartest coaches monitor both the stimulus and the response to make truly evidence-based adjustments.
