I’ve been measuring it on almost every jump for the past 4 months. Surprisingly the HR doesn’t go up right before the jump, but it increases approximately 1-3min after the jump. For me a “normal” jump will look something like : -climb/access up to 180bpm -meditation/relaxation before jump 80bpm -exit point/ready to go 80bpm -post jump (1-3min) 100bpm
I use a garming instinct. We tested the HR monitor with an actual HR machine and it is quite accurate.
If I take some preworkout or an energy drink before a climb it will be significantly higher.
If I am well rested it will usually be lower.
If security is sniffing around it will be higher.
I’ll try to make a nice data sheet when I get some time.
