Heart rate variability is an extremely sensitive metric. It fluctuates greatly throughout the day, from one day to the next, and from one person to another. People often wonder “What should my HRV be?” and “How does my HRV compare to others?” Younger people tend to have higher HRV ...
Whether relaxing with a good book or sprinting up a hill, your heart rate constantly fluctuates throughout each day. And so is the time between each heartbeat. Heart rate variability is the whisper that has a lot to say. Such minor variations tell us a lot about critical factors like ...
You now know that there are many factors that can cause resting heart rate fluctuations. It’s important to think about all of these if you observe any resting heart rate changes, as it’s likely to be a short term change. It’s relatively normal if your RHR fluctuates a lot and, for...
Heart rate time series exhibit complex behaviors including unpredictability2, stochasticity23, nonstationarity1,24, nonlinearity4,25, chaos25,26, bifurcation27, fractality6, and multifractality28. Quantifying complexity from heart rate dynamics has attracted a lot of research. For example, Renyi entropy...
widen, let out - make (clothes) larger; "Let out that dress--I gained a lot of weight" take in - make (clothes) smaller; "Please take in this skirt--I've lost weight" branch out, broaden, diversify - vary in order to spread risk or to expand; "The company diversified" ...
monitor is useless, and you might as well buy the slightly better looking Pebble Time without a heart rate tracker for $30 less at $100. The Pebble 2 + HR starts at $130, and that’s a lot to pay for an otherwise base-level Pebble watch with a heart rate monitor that doesn’t ...
Yes. If this is your question, then you have probably been on the path of weight loss for a while. And as you will observe, your weight fluctuates. 99% of the time a “diet” doesn’t work is due to stress in your system. Stress can be managed and dissipated throughThe Heart of ...
After 3 weeks, you should have a better appreciation and respect for your body. You should be able to realize that taking care of your body involves a lot more than just "following the protocol". It starts with an attitude of respecting your body and seeing your body as part of the ...
It is interesting to look at the spikes in heart rate while rushing through the stations. However, I’m not convinced that those 140bpm spikes are real. And by not convinced, I’m going with ‘not a chance in heck’. A heart rate of 139bpm is my Z2 rate – my long running rate...
Jul 23 – my physical energy is the same or a little less from one day to the next but my mental energy fluctuates up as well as down. It’s good today and I always feel weaker after a nap so I’ll skip it today. I’ll also have some coffee in my breakfast. ...
