Olympic rower Gevvie Stone has been getting more sleep.
She owes it in part to the WHOOP performance monitoring system she’s been using since last December, a wristband she wears at night that evaluates her strain and recovery. The thin, lightweight band does so by measuring and analyzing heart rate, heart rate variability (HRV), ambient temperature and motion, among other data points.
Stone is also a doctor, which helps her more deeply understand the data that WHOOP collects, and she believes that HRV is essential in measuring fatigue and recovery. “The fact that WHOOP was measuring HRV it definitely made me particularly interested in the product,” Stone says.
