Supervised Interval Training (Clinical/Rehab Settings)
Clinician-supervised interval training: one way to carry out what the sources on interval training and cardiorespiratory fitness studied, in which home-based HIIT was effective in healthy adults and patients (Tsuji 2023) and interval training was more effective than moderate continuous training in older adults (Yang 2023; Poon 2021).
Only within a supervised program with medical clearance
- Chest pain, pressure, or unusual shortness of breath during exertion
- Fainting, dizziness, or palpitations with exercise
- Known or suspected cardiovascular, metabolic, or renal disease without medical clearance
- Any symptom or instability during clinical exercise
How to do it
What the evidence says
This practice is one way to carry out what the sources on the concept entry (phys.cardio.hiit-cardiorespiratory-fitness) studied: interval training and cardiorespiratory fitness against moderate continuous training and non-exercise control; the recorded conclusions on this entry describe healthy adults, older adults, overweight or obese persons and patients, without naming cardiac rehabilitation settings. Tsuji 2023 (meta-analysis, 15 studies, 398 participants) reports home-based HIIT as an effective intervention for cardiorespiratory fitness in healthy adults and patients, comparable to lab-based HIIT and MICT. Yang 2023 (meta-analysis, 30 studies, 1973 participants) reports HIIT more effective than MICT for cardiorespiratory fitness and exercise capacity in older adults, and Poon 2021 (meta-analysis, 14 studies, 429 participants) reports interval training more effective than MICT in middle-aged and older adults. Supervision and medical clearance are this entry's own conditions, not a finding. The full account, source by source, is on the concept entry this practice links to (phys.cardio.hiit-cardiorespiratory-fitness).
- 'Heart patients must avoid intervals' (Tsuji 2023 reports home-based HIIT effective for cardiorespiratory fitness in healthy adults and patients; this entry keeps intervals for selected patients within a supervised program with medical clearance)

Each source below is shown with its study design and a link to the original study, or, where it is not a completed research paper, with what kind of record it is; those are not counted. This is the audit trail.
Why do some records show a record type instead of a study design?
A study design is shown for a completed, peer-reviewed paper. A registered protocol, a preprint, a conference abstract, a referee report or a book chapter has not been through peer review as a finished paper, so it is labelled for what it is, and it is counted in no source count. Where a record could not be confirmed as a completed paper at all, it says so rather than guessing. They all stay in the list, and their DOI still resolves, because the count of what was screened is part of the audit trail.
- Protocol / registration A registered plan for a review or trial, not its results.
- Preprint Posted by its authors before peer review.
- Conference abstract A conference summary rather than a peer-reviewed paper.
- Peer-review report A referee's report on a paper, not the paper itself.
- Guideline / position stand A recommendation derived from evidence, which is a step further from the data than the evidence itself.
- Book chapter A chapter in a scholarly book rather than a journal paper.
- Type not recorded Our record does not say what kind of publication this is, so it is counted in no source count. That is a gap in our data, not a judgement about the research.
