[Suggested workout] why suggest 10s Sprint workout if you can't track it

Hi,

I've been doing a suggested workouts for almost 2 months now. I have NEVER been able to get anaerobic training effect at the end of a SPRINT suggestion it always ends as BASE or sometime Tempo. I've tried different levels of straping of my watch in order to find a good level for too tight not to loosen etc. really everything there is.

From what I observe is just that the Heart Rate Monitor can't keep up with the sprints. very often after i do a 10 sprint @19-20km/h it shows a BPM of 130 .... :( i mean how? why ? especially it happens rather at spring 7th or 8th where i'm already at 2.0 anaerobic efficiency according to data screen.

I tried walking between sprint, slow running between sprints(seem to have better readings but my HR won't go down to 115BPM) There are surely another suggestions / workouts to do. The only way i see to properly track it is with Chest strap but I don't have one i just spent 700€ on sapphire version just to learn a month after that actually chest strap would be sufficient for me / more effective for me.

It is really frustrating. Why not suggest longer sprints with shorter rest like 10x30s@16km/h with 30-60s rest for example I've been doing that in the past with a coach. Since the speed is slower there less sharp movements of arm and therefore maybe the watch will be able to record the Heart rate more precisely.

Please Garmin when you suggest a workout take into the account whether we have a chest strap or not. Because basically I'm having Sprint suggestions 2 days in a row. because they all finish as BASE and sometimes as Tempo. I will end up having an injury first before just for once I am able to have a "anaerobic/sprint" workout label.

So frustrating.... ;'(

Garmin hasn't done as you suggest because that wouldn't fix the problem. There is no technology in existence that can accurately track heart rate on the wrist during sprints, even if they're longer…

That's why this suggestion without a chest strap feels pointless.

You won't gain anything even with a strap for a sprint that short. Physiologically your heart cannot react that quickly…

The sprint suggestion is completely useless. Personally I do sprint in HR zone not time zone based. Sprint until each zone 5 alarm and walk until reaching zone 3.

The best results are sprint uphill and…

Well to be clear I was not speaking about the reaction delay. More about the fact that with the watch some sprints HR isn't detected or it is detected totaly wrong.

Such short sprint intervals at maximum effort are intended to train the nervous system and muscles for maximum cadence and acceleration. They are too short to produce anaerobic effects, nor to increase VO2max or for analyzing the HR/pace curve.

Muscle response and stamina, and cardiovascular endurance are different things that should be trained. I.e. a 100m runner needs to train differently than a long distance runner.

So I think the suggested workouts should be improved depending on the goal of the training. There isn't one training plan that fits all.
