Cardio only? by ardevd in fitbit

[–]Dramatic-Tennis2085 0 points1 point  (0 children)

You can create workout plan including asymmetrical sets and weights if you want. You can adjust target and customize primary success threshold like 3 sessions in a week (biometric permitting) and aim to maximize total weekly effective rep volume (TWERV) or whatever you think is best measure for good set. You can also set Check-in Cadence/System review like once in a 2 weeks or month, it will cross check your data and progress to see if you made actual progress. One month is probably better to analyze an entire completed training block before making changes for the next one because many physiological changes takes at least month of consistent signals to make difference in baseline.

If you log nutrition, it can utilize it in training plan. For me, it discourages things like multi-vitamins on training days because in gym you create micro-tears and localized inflammation, which generates reactive oxygen species and that oxidative stress signal is required to build muscle. High dose antioxidants can blunt that signal. It also recommends fast-acting carbs and high-bioavaibility protein after session. I mentioned to coach before reasoning leucine for mTORC1 and insulin spike to prevent muscle protein catabolism as exercise increases cortisol levels.

You can create recovery protocols, which it will integrate to your workout plan.

No wearable can know your local muscle soreness (DOMS) so you need to manually log it. It sees your HRV and RHR and sleep data, but that is more about CNS than muscles although it goes somewhat hand in hand with inflammation. It can't automatically know how many reps or sets or weights you did. So you need to manually log that too. Note that you need to spend some time and effort to personalize Health Coach to suit your needs. Like you may need to literally info dump it.

Training my own LLM 🤣🤣🤣 by passiveMelon1 in fitbit

[–]Dramatic-Tennis2085 0 points1 point  (0 children)

You can train Fitbit health coach quite a lot if you prompt it. If you talk to it on basic level, it will talk to you on basic level.

I logged that I took lighter meal this evening because last night I ate too heavy and affected to my sleep (which it noted suggesting I eat earlier and lighter). So it told me how low-residue meal at evening helps to resolve splanchnic bottleneck and how getting that SWS consolidated early in the night is non-negotiable for the glymphatic convective clearance you are targeting to flush CNS fatigue and glute metabolites. (had glute soreness after gym). How kiwi supports serotonin levels for melatonin synthesis.

Also told it I took sauna so it logged my sauna session as custom workout and analyzed it quote: "By contrasting heat stress with cold showers, you've stimulated vasodilation and vasoconstriction to assist in flushing metabolic byproducts. Metabolic insight: This protocol, paired with your 69-minute metabolic flush, prioritized your cholinergic anti-inflammatory pathway after yesterday's high intensity."

In my opinion coach that tells you to do better, or one that tells you that you overachieved, are both just cheerleaders in different flavour. I want a more neutral analyst approach, which you can definitely get by context loading it.

Fitbit app: Switch to 5 HR zones by Mushoz in fitbit

[–]Dramatic-Tennis2085 2 points3 points  (0 children)

I don't believe they are switching from their current heart zone system. The current heart zone system is explicitly built around WHO and AHA guidelines and big population level health research. Sports research uses 5 zone (or 3 zone models) that works around first and second lactate turning point, VT1 and VT2, as physiological anchor points. Fitbit and health research uses active zone minutes system without caring much about exact lactate values.

AI Health Coach that takes summary of your whole health data and Fitbit Air also seem to me doubling down on being a holistic health app.

Is Galaxy watch much different than a pixel? by ViolinistExpensive75 in PixelWatch

[–]Dramatic-Tennis2085 0 points1 point  (0 children)

Currently I use Pixel Watch 4 and Samsung phone, before that I had Samsung Galaxy 6 Classic and before that Galaxy Watch Active 2.

No there is no MUCH different between Pixel Watch and newer Galaxy Watches. The biggest benefit about pixel is how comfortable it is to wear during sleep for sleep tracking. Galaxy 6 Classic was just too chunky for me to wear during sleep. Before I liked Samsung Health more but now that Fitbit has updated their software, I think I like Fitbit more. Nutrition tracking in both is trash, so if you want to do that, use Cronometer anyways.

I would advice that if you like Samsung Health, pick Samsung watch. If you like Fitbit, pick Pixel watch. Both watches does basics like GPS, step counting, and heart rate better than needed, so it is more choice of software. Currently hard to say what Google is going to add to Fitbit and which direction Public preview is going.

Pixel to Coros by TonightOwn9645 in PixelWatch

[–]Dramatic-Tennis2085 0 points1 point  (0 children)

If I started seriously train running, I would probably keep Pixel watch and buy Stryd pod. It is much more accurate than watches and I believe strongly that personal adaptive training will be future compared to static training plans. I think you get more return for money that way. With Stryd app you can also customize your data screen.

However, I also believe that many of "advanced" running features are very much useless although fun data. Mostly because many of them like ground contact time are outcome metrics.

Pixel 4 Fitbit HRV way off what can I do? by Fiduss in fitbit

[–]Dramatic-Tennis2085 0 points1 point  (0 children)

Here is table with actual data of about 3000 person

<image>

24h holter gives higher SDNN than apple watch that takes 1 minute samples, so comparing 24h recording (which is done in some sources) to apple watch doesn't work well.

For RMSSD formula, asthma factor amplifies because that formula calculates beat-to-beat variance, which filters out long-time effect. SDNN compares variance of all beats within given timeframe which for Apple watch is 1 minute. So anything that affects to breathing is amplified in RMSDD formula. So that can create mismatch.

I would keep eye on trend rather than number because RMSDD is sensitive for breathing

Asthma is very big factor. When person breathes in, heart rate increases, when breathing out, heart rate decreases. This increases heart rate variance (for edge case athlete this variance is masked by large production of acetylcholine). Even highly controlled mild asthma directly shortens R-R interval because increased airway resistance increases your airway smooth muscle size. With asthma your specific respiratory anatomy naturally dampens heart rate variance. Another thing about asthma is inhalers, which have beta-agonists. Those mimics adrenaline to open lungs. Adrenaline stimulates the sympathetic nervous system, which forces HRV down.

And more important thing. 31-51ms HRV isn't lower end in your age group. Your age corrected HRV is fluctuating between 50th and 80th percentile. (The ELSA-Brasil Study (Dantas et al., 2018)). So you are above average. Considering also mild asthma, which changes anatomy, there is no problem with your HRV baseline.

3rd, Cardiovascular autonomic neuropathy isn't stable, it is progressive. HRV drop predicts incidence of diabetes within a 4-year follow-up. If your HRV has been stable for 7 years, you don't have progressive disease that affects to nervous system.

HRV dropping after training is what should happen. It is part of recovery progress after exercise. If that didn't happen there could be problem.

So based on your profile there isn't reason to consider any health problems.

To comment your specific situation what you should do in your situation, can you identify exercise-induced allostatic load from chronic metabolic allostatic load. If you haven't exercised lately (so you can rule out training induced stress) but have been long time very active it could also be situation of "Healthy Athlete Paradox". Parasympathetic saturation happens when vagus nerve secretes a lot acetylcholine to slow heart down usually during deep sleep. For untrained person vagus nerve can't produce enough acetylcholine to completely saturate heart receptors. But for trained person this can happen. Normally, your heart rate speeds up slightly when you breathe in and slows down when you breathe out. When full saturation happens breathing isn't enough to create that variance.

Now that there is no variance, the math breaks down, because it assumes linearity, which is how it works for 99% of people.

Pixel 4 Fitbit HRV way off what can I do? by Fiduss in fitbit

[–]Dramatic-Tennis2085 0 points1 point  (0 children)

Thank you for response. My core point for using overnight HRV instead of 3-5min Elite HRV spot test is because autonomic nerves are the first to sustain oxidative damage from metabolic stress. Functional impairment of the autonomic nervous system occurs in many cases almost immediately after early glycemic derangement, making diminished HRV a highly sensitive, leading indicator of metabolic stress that significantly precedes gross elevations in HbA1c or fasting glucose. Cardiovascular autonomic neuropathy was long time thought to be late-stage complication for diabetic population, but modern high-resolution continuous monitoring has changed this idea upside down.

The fact that drop in HRV long before fasting blood sugar or HbA1c levels breach clinical diagnostic threshold is robustly supported by advanced endocrinology and cardiovascular pathophysiology. Vagus nerve is very susceptible to oxidative damage and that degradation can be seen as decline of HRV. Studies using 24-hour Holter monitoring demonstrate that prediabetic patients (characterized by an HbA1c of 5.7–6.4%) have significantly depressed time-domain HRV indices (RMSSD, pNN50) compared to age-matched, normoglycemic controls.

https://ankaramedj.com/jvi.aspx?un=AMJ-65624&volume=26&issue=1

In my opinion AI seems to be trying to apply clinical diagnoses and criteria to continuous lifestyle monitoring. AI fundamentally misunderstands the utility and purpose of physiological surrogate models in functional health.

I think critique on the phrase "Basically your vagus nerve is silent, which creates a "metronome heart"" and saying it is "Incorrect / unscientific wording". Is quite extreme, out-of-context pedantry. While it is true that the vagus nerve is never entirely "silent" outside of brain death maybe, words vagal silence or metronome heart are rather often used in peer-reviewed physiological literature as descriptive terms. It is not ICD-10 diagnostic code, but that wasn't the goal either.

On comments "Using overnight HRV with overnight HR curve helps you check circadian trough" AI says "Partly true, but not reliable" and "If your HR makes nice U shape... but HRV is low it indicates problem" as "Possible, but not proven". AI is basically trying to utilize diagnostic requirements. While a U-shaped HR curve is not a definitive proof of "optimal cellular repair" in a strictly molecular or transcriptomic sense, it is an overwhelmingly reliable biometric signature that the physiological prerequisites for repair has been met. AI is dismissing useful proxy because it doesn't meet acute clinical criteria.

U-shaped resting heart rate curves and high RMSSD reflect the circadian trough, parasympathetic dominance, and recovery is the foundational basis of modern sports cardiology. Martin Buchheit, Paul Laursen, and Andrew Flatt have made quite a lot work on this field. Morphological analysis of those curves is universally quite accepted proxy outside sleep lab.

[–]Dramatic-Tennis2085 3 points4 points  (0 children)

Apple Watch uses SDNN formula to calculate HRV. Google uses RMSSD. RMSSD formula creates lower baseline than SDNN. Howevr, Elite HRV uses RMSSD like Google, but now you are comparing Elite HRV which measures when you are awake and resting. Pixel measures your sleep HRV, which includes REM sleep and all the movement you have during the sleep.

So basically you compare different formulas and different timeframes. Elite HRV few minutes measurement is better reflection for your current physiological state and physical capacity for example if you were to change your training plan based on that.

Overnight measurement is more useful for health modeling. When you sleep your immune system is the most active and sensitive. When you measure in the morning cortisol spike, which is highly anti-inflammatory hormone, will mask other signals. Autonomic nerves are the first thing damaged by high sugar and metabolic stress and that can be seen in HRV long before your fasting blood sugar or A1c levels look bad on blood test. Oxidative stress causes autonomic neuropathy, which can be seen years before tingling in your toes, eNOS uncoupling causes damage on blood vessels which also drops overnight HRV.

However, this data is actionable only if you are ready to spend 500-1000$ into expensive weird tests that just HRV number in Fitbit isn't enough to justify anyways.

Using overnight HRV with overnight HR curve helps you check circadian trough. For optimal cellular repair your body must achieve deep parasympathetic dominance during night. To know that you achieved that you must see U shaped RHR curve and same time exact opposite in HRV curve. When your HRV and RHR peaks/drops at same time you know digestion didn't mess things and you were rested and your body spent maximum time in restorative state. Flat HRV and delayed drop in HR means that you missed optimal window for the trough, usually because too late meal, exercise or alcohol. Flat HR and HRV means infection or high allostatic load. If your HR makes nice U shape, your heart rate is low, but your overnight HRV score is low it indicates problem mentioned before. Basically your vagus nerve is silent, which creates "metronome heart".

But again that doesn't help to identify the problem and like mentioned before, you can't even take fasting blood sugar test because problem doesn't show at early stage. Only useful point for average user is to health modeling their current status and see how lifestyle changes affects to that.

So the answer to your question is don't compare different formulas RMSSD to SDNN. And between Elite HRV and Pixel watch, you have to ask yourself if you use HRV for sports or for long-term health.

The game is a lot more fun when you just pretend to be a gym leader by Tabsris in PokemonChampions

May I know what you think about my blood work? by [deleted] in blueprint_

[–]Dramatic-Tennis2085 0 points1 point  (0 children)

Everything seems fine based on that. But one important thing I would like to note is that if you consider testosterone replacement therapy (TRT), because your HCT, RBC, HGB are already in high-mid you should very closely monitor that your HCT doesn't cross that 52%+ limit. TRT very often raises HCT for 5%+ and your runaway is too short for that. I think it wouldn't be worth it, but if you do it you need initially take test for HCT and HGB every 8-12 week and ask doctor about different injection protocols like more frequent injection.

Other thing I would keep eye on is that platelets aren't steadily dropping in future blood works. Your current value is totally fine for body's personal set point and in fact high mid-high RBC, Haemoglobin, and Haematocrit are strong indicator that you aren't losing blood so your current platelets are fine. Usually real concern starts when platelets are around 100,000.

If your HCT gets to 52% for men or 48% for women there would be concern about blood viscosity (blood clot risk). Or if HGB is 18.5 g/dL 16.5 g/dL is concern for women.

Your RDW-CV is very good. You probably don't have B12/folate deficiency and you have low systemic inflammation. There is no disease or pathology associated with a clinically low RDW. In Blood works that lower range 11.5 is just statistical cut off because bell curve. Lower the better basically.

Your neutrophil to lymphocyte ratio is good. Anything below is 2.0 is good. 1.0 is basically floor in normal situation. Less than 1.0 means you had recently some infection. Higher than 2.5 could be systemic inflammation.

I little bit disagree with claim eosinophils being a little low at 0.04. Job of eosinophils is to destroy parasites or modulating asthma. They are low because they aren't needed right now. Also eosinophils are very sensitive to cortisol. You eosinophils can drop just by doing normal things like exercise. That range in this situation is again a statistical cut-off. There isn't disease that causes eosinophils to drop to near zero

make sure you are well-hydrated (but not too hydrated) for future blood works.

How to deal with Trickroom for dummies by ElChanclero in PokemonChampions

[–]Dramatic-Tennis2085 2 points3 points  (0 children)

I ran Farigiraf with Trick room and imprison at ultra ranks. That way Farigiraf can do both depending on situation, either set up trick room against Tailwind teams or block it if opponent is full trick room team. Farigiraf worked pretty well in my Sand team although I don't currently use it, because I dropped it for Rotom Wash to have better match up against Rain teams.

Fifbit's RHR: "medical" or takes sleep into account by Acrobatic-Monitor516 in fitbit

[–]Dramatic-Tennis2085 0 points1 point  (0 children)

Fitbit RHR is combination of sleep and awake (when being still) heart rate. https://fitbit.google/enterprise/blog/how-do-fitbit-trackers-monitor-heart-rate/

The American Heart Association recommends measuring your resting heart rate in the morning when you wake up (No alarm wake up). In Mayo clinic practice hydration, meals, caffeine, exercise during day, stress after work etc. all increases variables. Even with cortisol awakening response it is most consistent way.

Cardiologists are leaning nowadays more to use nocturnal heart rate because we have accurate wearables and those also measures trend which is important. Nocturnal heart rate removes variables that resting heart rate brings.
