AI generated summary

Wearables such as sports watches provide plenty of data on heart rate, sleep, and recovery — but their real value depends on how coaches interpret and apply this information.

• Measurements: Heart rate and HRV are useful for tracking trends, though wrist-based sensors are less accurate during intense activity. Sleep data offer only a general overview.
• In training: Features like Training Readiness, HRV Status, and Running Tolerance can help tailor load and recovery — but only when viewed in context.
• Limitations: Measurement errors can occur due to motion, skin tone, or tattoos. Data should guide, not dictate.
• Coach’s role: Use wearables as a conversation and decision-support tool, not as a replacement for observation or athlete feedback.
• Key message: Technology adds value when human insight, data, and context come together — measuring only matters when you understand what it means.
