[QUOTE="FireDragon76, post: 77640155, member: 330042"] I went to the gym before church and I did some low intensity cycling because my left knee was feeling stiff, and I have found sometimes low intensity exercises helps with that. Nothing hard, I did'nt even sweat, just pedalling at a recovery intensity of about 35 - 40 percent intensity). I also did some glute leg presses on a machine with light weight, just to practice using the machine and to get in a bit of extra volume (I'm not sure the Sci-Fit machines are engaging my glutes enough, even pedalling backwards, it just feels lacking). I also performed a few deadlifts with a 12 lb kettlebell, just to feel what that was like. Being somewhat active felt alot better than just being stiff on a rest day. I also did some reading and some experimentation using Garmin's Body Battery and a spreadsheet, to discern the relationship between heart rate and stress score, and how Body Battery works. I wanted to understand why I got such radically different scores from HRV morning readings with EliteHRV. Usually, Heart Rate Variability works like a snapshot and requires an ECG chest strap or a really good optical sensor and a noise filter, and there's just too much noise in a wrist-worn watch's optical sensor to make a real time reading moment to moment: all of that extra processing takes time, too- minutes or seconds. So what the Garmin watch does is to only see heart rate variability trends, but not discrete heart rate intervals and it works off a trend or rolling average, feeding into a non-linear stress model that's also partly based on heart rate. This kind of system is a kind of gamified, really crude metric of stress or fatigue. It's meant to encourage exercise pacing and better lifestyle choices, but it's a very crude metric as far as actually assessing the physiological effects of exercise on readiness. HRV, on the other hand, is less gamified and is used by athletes to gauge readiness or recovery, by creating daily, rather than moment-to-moment, trends. It's meant to augment or replace older tests, like orthostatic pulse tests that athletes used to do (some, such as Polar's Orthostatic Test combine both HRV and an orthostatic test). [/QUOTE]
