What we measure.
Year 1 data collection begins with Cohort 1 (Fall 2026). This page documents our measurement framework — outcomes, methodology, limitations, and reporting cadence.
We have no outcome results to report yet. Cohort 1 has not started, so no participant data exists. We are publishing the framework in advance, before we have any results to present, so that our measures and their limits are on the record first and cannot be chosen afterwards to flatter the outcome.
Outcome measures
Pre/post per cohort.
- —Grip strength (kg) — dynamometer or chair stand proxy
- —30-second chair stand repetitions
- —Sit-to-stand repetitions
- —Adherence: % of prescribed sessions completed
- —Retention: % completing all 12 weeks
- —Self-reported training confidence (1–10 scale)
- —Net Promoter Score
- —Self-reported independence/mobility confidence
- —Likelihood to continue training post-cohort
- —Cohorts per year
- —Participants per cohort
- —Geographic distribution across Canada
Methodology
How the numbers will be produced.
Collected twice, by the participant
Every measure is taken in week one and again in week twelve. Participants take their own measurements at home, following a written and video protocol, and enter the result in the training app. Nobody visits a clinic and nobody is examined by us.
Chosen because they are practical, not because they are ideal
A research lab would use DEXA scans and force plates. We use the 30-second chair stand and sit-to-stand because they are validated field measures of lower-body strength in older adults, they need no equipment, and a participant can perform them alone in a kitchen. Where a grip dynamometer is unavailable we record the chair stand as a proxy and label it as such.
Adherence is tracked automatically
Session completion comes from the training app rather than from self-report, so adherence and retention figures do not depend on anyone remembering accurately. This is the most reliable data we will hold.
Reported per cohort, then aggregated
We publish a short summary after each cohort completes and a fuller report at the end of the first four cohorts. Both will state the number of participants who started, the number who finished, and the number whose measurements were usable — not only the averages of those who did well.
Limitations
What these numbers will not prove.
- —There is no control group. We cannot claim that observed changes were caused by the program rather than by anything else happening in a participant's life.
- —Measurements are self-administered, which introduces error that a supervised assessment would not have.
- —Cohorts of 25 are small. Results will be descriptive, not statistically powerful, and we will not present them as evidence of population-level effect.
- —Participants opt in, so they are likely more motivated than the general population of Canadians aged 55 to 70.
- —We are not a research institution and our reporting is not peer reviewed. Where we cite evidence for resistance training itself, we cite the published literature, not our own results.
Participant data
Consent first, aggregate only.
Participants are told at application what we measure, why, and what we will publish. Taking part in the program does not require agreeing to have your data included in our reporting; a participant can decline and still complete the cohort.
Published figures are aggregate only. We do not publish individual results, names, or anything that could identify a participant, and we do not publish photographs without separate written permission.
We do not sell participant data or share it with advertisers. A participant can ask us to delete their information at any time by writing to programs@jasclairwellnessinstitute.com.
Year 1 targets
4 cohorts · 100 beneficiaries · Fall 2026.
These are targets, not achievements. Each date below is a plan we expect to be held to, and we will say plainly on this page if a cohort slips or a target is missed.
