@doctorinigo On the subject of screening for early detection, if you're a man over 50 please get PSA tested. My partner cajoled me into it 6 mths ago. PSA high (13 ng/L), scans, biopsy and robotic prostate removal followed 3 wks ago. Fully mobile already & aim to be on my bike in a few weeks.

A 7 day moving average smooths out the daily variations in practical HRV measures such as RMSSD to let you see your baseline and trends https://t.co/RpLyeviAh8

Sharpen your axe 🪓 #HRV

Certainly true in my experience - work & lifestyle stress limits the amount of training your body can absorb. All subtracted from your 'physiological headroom'

[Andrew Flatt @andrew_flatt]

In trained individuals, non-training stress tends to affect ANS activity more so than the training stress that they’re accustomed to.

This means that lower/less stable HRV often reflects the stress that diverts energy away from recovery processes & impairs training adaptations.

@DajoSanders @INEOSGrenadiers @TeamDSM Great news - very happy for you Dajo!

[Simon Wegerif @SimonWegerif]

ie the better you relax before bed, the better you will sleep and the better your HRV will be the next day: the start of a virtuous cycle

[Andrew Flatt @andrew_flatt]

Stress, sleep, & parasympathetic activity are key contributors to individual variation in training responses, & they’re interrelated.

↑Pre-bed HRV = ↑sleep

Pre-sleep slow paced breathing = ↑HRV & ↑sleep

↑Sleep = ↑next-day HRV

[Andrew Flatt @andrew_flatt]

Same HRV tools/methods we’ve used to monitor training adaptations in athletes seem useful for tracking health and wellbeing in the general population.

@fred_wright0 You did brilliantly - don't be so hard on yourself!

[Simon Wegerif @SimonWegerif]

In particular, aerobic exercise is one of the very few interventions known to reduce aortic stiffness. Increased aortic stiffness is a key contributor to high systolic BP with aging.

[Andrew Flatt @andrew_flatt]

Cardiac ANS activity, blood pressure, & aortic stiffness worsen with age, are not unrelated, & increase risk. Intentional lifestyle change to improve parasympathetic function may alter their trajectories, & HRV tracking may be the most accessible way to guide the process.

@JuliaHShaw i remember going as fast as I dared during the M312, when a young Sky Pro zipped round on the outside making everyone else look like they were standing still

[Simon Wegerif @SimonWegerif]

@andrew_flatt I think that's something we've suspected for a long time! Would love to understand more of the underlying mechanism

[Steve Magness @stevemagness]

Developing endurance is simple, yet difficult.

How do you get fitter aerobically? What should I worry about to get better? I get asked this question all the time. So here's the answer

From beginner to Olympian, here’s what to worry about when it comes to endurance development:

[Alan Couzens @Alan_Couzens]

For the love of God, people:

Just put a HR strap on each morning and do the bleeping test!

You put 2,3,4 hrs EVERY day into training but donning a HR strap for a minute or 2 each morning to get accurate data & ensure that training is actually productive is too 'inconvenient'?🙄

[Alan Couzens @Alan_Couzens]

#HRV guided training in a nutshell:

* Don't plan your recovery days. Take them when your body needs recovery.

* Don't plan your hard days. Do them when your body is poised to get the most out of them!

#NotRocketScience #CommonSense

[Andrew Flatt @andrew_flatt]

I’m a fan of active recovery & certain modalities, but rest days with no or minimal team obligation are underrated. Few things allow players to shut it down & recover better than simply knowing there’s nothing on the calendar tomorrow. Typically see a nice HRV bump the next day.

[Simon Wegerif @SimonWegerif]

@andrew_flatt @myithlete I'm sure my numbers are better than 10 years ago. Some unavoidable down periods due to life stress or illness, but upward trends in HRV have given the most motivational feedback to reinforce healthy habits over the long term.

[Simon Wegerif @SimonWegerif]

The promise of training personalised to what your body is able to absorb and benefit from the most has been my ambition since I started measuring HRV with ithlete 11 years ago! @myithlete

[Alan Couzens @Alan_Couzens]

No matter what level you race at - from recreational athlete all the way to World Class Pro, if you're not using #HRV to guide your training, you're leaving some performance on the table!

[Simon Wegerif @SimonWegerif]

@Point1_Athletic @Alan_Couzens @myithlete @andrew_flatt Hi Chris - not so likely I think. Parasympathetic overreaching is associated with adrenal fatigue (production and/or sensitivity), and in my experience is very stubborn to budge. Can't get HR up during exercise no matter how hard you try!
