I was wondering if Frontier has determined desirable training loads based upon age and other factors, or if it is only a single number for all users. Thanks!

Hi – I recently forgot to turn off the monitor after a 2 hour cycle, letting it run for another hour and noticed that my QTc at rest is higher than while exercising and above 440, whereas it is below while exercising. Is this significant?

Hi Nemel, Our QTc algorithm is based on Bazetts formula, I.e. QT interval(in ms)/square-root of RR interval (in secs). This formula leads to most people having higher QTc values at rest than during exercise, so that is expected:).
Medical literature states that 440 – 500 is a spectrum where QTc MAY be significantly prolonged but needs contextual…Read More

I have observed that my cardiac strain is rarely zero, even when at rest. On checking while asleep recently, my strain varied between 0.01 and 0.03. Is this likely to be significant from a cardiovascular perspective?

It is very normal to have a small amount of variation in cardiac strain at rest. Cardiac strain is significant only if the value is greater than 0.1 mV, and the value of Cardiac Strain should be interpreted with context of what you were feeling at the time when the Cardiac Strain was high. So we wanted to ask you- did you have any heart symptoms…Read More

Has anyone else noticed a drop in their maximum heart rate after being infected by COVID 19?

Good question. I might be down by about 4 or 5 bpm though I think that may be due a difference in my training post Covid. My heart rate was higher than normal at comparable power outputs for the first few months and I tapered down slightly on training as a result.

Thanks Amo. It’s a strange one. My threshold HR is similar but 4 or 5 beats down. My max HR is down by 10 beats or so. I’m basically unable to achieve the same power output (rowing) I was able at the beginning of 2020. I’m guessing my cardiac output is reduced, but I’m no expert. I contracted COVID in November 2020 and wasn’t too badly affected,…Read More

As a healthy female amateur cyclist in my early 60s my cardiac strain is usually around 0.12 max and 0.06 average over distances of around 50km cycle and on occasion close to 100km. I have no discomfort cycling and the summary indicates that the average strain is minimal. The max strain measurements of 1.2 are short lived and look like a small…Read More

Occasional spikes are very unlikely to be significant, especially if they’re not associated with any symptoms like chest pain, breathlessness palpitations, dizziness or unusual fatigue. A simple way to check this on a ride is to set a CS upper limit alert at 0.18mv, and only modify your exercise intensity if you get 3 buzzes in a row, or if you…Read More

The Training Load Goal starts from a default setting as per the WHO guidelines, but then updates every week according to the individual’s age and fitness levels 🙂
