Wearable Strain Scores Replace Gut-Feel Training Decisions in Pro Locker Rooms
WHOOP bands sample heart-rate variability and respiratory rate every second, then feed the raw signals into a proprietary recovery algorithm that outputs daily strain and sleep scores. Teams integrate these scores into practice planning software so load is capped or increased based on the previous night's recovery metric. The platform currently supports more than 20 professional franchises.
Coaches replace generic training plans with individualized load prescriptions derived from nightly heart-rate variability and respiratory-rate data. The result is fewer soft-tissue injuries and steadier performance across a season rather than peaks followed by forced rest.
WHOOP raised $200 million at a $3.6 billion valuation in 2021 with participation from Kevin Durant and Patrick Mahomes, and now supplies recovery and strain scores to more than 20 professional teams across the NBA, NFL, and MLB.
Step 1: Purchase a WHOOP 4.0 band and pair it with the mobile app using the athlete's team email. Step 2: Wear the band continuously for seven nights so the baseline recovery algorithm calibrates to individual heart-rate variability. Step 3: Each morning, open the WHOOP app, note the strain target displayed under 'Recovery,' and adjust that day's training volume accordingly before the first session. URL: https://www.whoop.com/
