> Longevity for Women: Biological Age, VO₂max & Sleep — PeriTrack

Longevity for women: your biological age, your training, your sleep — in one picture

PeriTrack combines your blood work with data from Oura, Polar and Withings: biological age, VO₂max time, zone 2 minutes, strength sessions, steps, sleep parameters and your real weekly expenditure. It does not diagnose — it tells you whether your numbers are good for your age or merely normal.

Biological age from routine blood markers (PhenoAge approach), tracked over time
Five training pillars: VO₂max time, zone 2, strength, intensity, steps
Age-adjusted sleep parameters: total sleep, deep sleep, efficiency, sleep debt
Weekly expenditure: your own resting expenditure plus real activity
Cardiovascular, neurocognitive and metabolic risk profiles from your own values

Sound familiar?

Your ring says readiness 82 — but not what that means for your ageing.
You train a lot, but nobody tells you whether it was the right kind of training.
Your labs are "all within range" — and you do not feel that way.
Three apps, three answers, no whole picture.
Most longevity advice is measured on men and ignores hormonal status.

Why a ring or a longevity app is not enough on its own

A sleep score says nothing about healthspan — deep sleep share, efficiency and sleep debt do.
Active minutes are not zone 2 minutes, and certainly not time in zone 5.
Biological age needs blood: inflammation, metabolic, blood count and kidney markers.
Strength training is a core longevity lever and shows up in wearables only as "a workout".
Your energy expenditure moves with cycle, sleep and thyroid status.

A ring measures your sleep. PeriTrack tells you what your sleep, your training and your blood work say together about your biological age.

Your six longevity metrics

VO₂max training (zone 5, around 10 min/week) From the heart-rate zones of your Polar sessions — the short hard time at your limit.
Zone 2 minutes (≥ 150 min/week) The calm aerobic base, merged from Oura activity and Polar training zones.
Strength sessions (≥ 2/week) For muscle mass, bone density and insulin sensitivity.
Steps (≥ 7,500/day) Everyday movement read straight from Oura.
Sleep parameters Total sleep, deep sleep, efficiency and sleep debt — age-adjusted for women 40+.
Biological age Calculated from blood work, alongside reproductive age and three risk profiles.

What each device contributes

Oura Ring: sleep, deep sleep, efficiency, resting heart rate, HRV, steps, active minutes.
Polar: sessions with heart-rate zones, zone 5 seconds for VO₂max, zone 2 time.
Withings: weight and body composition, i.e. fat and lean mass.

Three steps to get started

Connect your devices Link Oura, Polar and Withings through their official interfaces.
Enter your blood work Add the lab results you have — inflammation, metabolic, blood count and kidney markers.
Read the trajectory and adjust Biological age, training pillars, sleep and weekly expenditure over time.

What this is based on

The PhenoAge model derives a biological age from routine blood markers and has been linked to mortality and disease risk. Levine et al., Aging 2018
Higher cardiorespiratory fitness was associated with substantially lower mortality in a large cohort. Mandsager et al., JAMA Netw Open 2018
More steps per day were associated with lower all-cause mortality, with the curve flattening above roughly 7,500 steps in women. Paluch et al., JAMA Netw Open 2021
Muscle-strengthening activity was associated with lower all-cause and cardiovascular mortality in a meta-analysis. Momma et al., Br J Sports Med 2022
Training in the moderate aerobic domain ("zone 2") is associated with mitochondrial capacity and fat oxidation. San-Millán & Brooks, Sports Med 2018
Deep sleep share declines measurably with age, which is why sleep values are judged age-adjusted here. Ohayon et al., Sleep 2004
Across the menopause transition, body composition shifts measurably toward more fat and less lean mass. Greendale et al., JCI Insight 2019

What is my biological age?

It describes how "old" your measurable body functions look compared with your date of birth. PeriTrack calculates it with the PhenoAge approach from routine blood markers and shows the difference from your calendar age. It is an interpretation, not a forecast.

Can I lower my biological age?

The markers it is built from can change through movement, sleep, nutrition and inflammatory load. Promising a number of years back would be dishonest — what you can see is the direction over months.

How much zone 2 do I need per week?

Around 150 minutes per week in the calm aerobic range is the usual orientation. PeriTrack merges your zone 2 minutes from Oura and Polar.

How do I train VO₂max after 45?

As intervals at your limit, classically about 3 minutes hard and 3 minutes easy over several rounds. Roughly 10 minutes of real zone 5 time per week is a realistic start; the zone 5 seconds come from your Polar sessions.

Is my Oura Ring not enough?

The ring provides the best raw data but knows neither your blood work nor the research targets that make it meaningful. PeriTrack adds that interpretation and does not replace the ring.

Which blood tests do I need for longevity?

Relevant markers include ApoB, Lp(a), CRP, HbA1c, fasting insulin, homocysteine, albumin, creatinine and blood count parameters such as RDW and MCV, plus thyroid and hormone values.

Is longevity different for women?

In important ways, yes: muscle and bone loss accelerate across the transition, deep sleep changes, fat distribution shifts, and cardiovascular risk rises as estradiol falls.

Do I need a wearable to start?

No. You can enter labs, weight and training manually; with devices connected, the movement and sleep side runs automatically.

Is PeriTrack a medical device?

No. PeriTrack does not diagnose and does not replace medical care.
