Nelly Korda has a wonderful poker face. She occasionally flashes a smile or displays a look of discontent during a round, but she always seems calm.
Her Whoop device, however, tells no lies and it shows just how excited she was when she tapped in to win the women’s competition at the Tokyo Olympics and when she received her gold medal.
According to Whoops statistics provided by the company, Korda “reached a 19.0 (out of 21.0) day strain, her highest of the week, following her final day of play.” Her average heart rate during the final round was 128 beats per minute with a 154 bpm spike after she made her final putt.
nullBut she hit her max heart rate on the medal podium, reaching 172 bpm.
By comparison, when Korda won the KPMG Women’s PGA Championship for her first major title, her average heart rate in the final round was 136 bpm and her max was 178 bpm. Her day strain was 19.9 out of 21.0.

Strain is a summarizing metric of the cardiovascular load - the level of strain your training takes on your cardiovascular system as based on your heart rate - achieved during an individual Activity or over the course of a day. Strain is scored on a scale from 0 to 21.
In general, the Strain scale is divided into 4 categories, shown below:
Light Strain (0-9) - This strain category indicates room for active recovery with minimal stress being put on the body.
Moderate Strain (10-13) - This category indicates moderate stress is being put on the body, which helps maintain fitness.
High Strain (14-17) - This category indicates increased stress and/or activity which helps build fitness gains in your training.
All Out (18-21) - This category indicates all-out training or a packed activity day that put significant stress on the body and may be difficult to recover from the day after.

This recording of Nellie Korda demonstrates the mental aspect of golf nicely.
When Holter monitor first came out in 1970's, one of interesting studies was
the recordings of interns' heart before and during and after case presentations
at weekly Medical Grand Rounds at a University Hospital.
Their heart rate exceeded 170 per minute surpassing the heart rate during skiing
by the same interns at Vale, Colorado, which was under 170.
My mentor during my Cardiology fellowship used to joke about the fact that
interns and residents ought to be thankful by their leading a stressful life
which automatically conditions their CV system.
The Whoop first determines your maximum heart rate, then uses that number to establish your personal heart rate zones. It then monitors the duration of time you spend in each of your heart rate zones to calculate your strain.
