University, grant and patent activity in a topic dossier concerns that wider field; it is not a hiit-specific total.
Different records. Different questions.
This is the composition of the initial 24-record selection, not the entire collection. Open a group to inspect its supporting records. Publication types and existing automated evidence labels describe records, not their quality or conclusions. Unclassified records remain in “Other research records”.
The recent trail.
Recent sources in this selection: publication months for publications, registry update months for registrations.
Good questions to bring along.
What can I learn about hiit here?
See which permitted records mention this object, follow the topics and other objects connected through those records, and inspect the sources. Whole foods, preparations, extracts and isolated compounds keep separate identities.
Do these records establish a benefit?
A mention is a starting point for discovery. Open each original source to assess the study design, population, findings and limitations. A trial registration describes planned or registered work; it is not itself a result.
How can I compare related objects?
Open a connected object and compare the actual records, preparations and research settings. “Mentioned in the same record” explains a navigation link; it does not establish equivalence, composition or causality.
How complete is this picture?

HIIT at Home: Enhancing Cardiorespiratory Fitness in Older Adults-A Randomized Controlled Trial.
Effects of different HIIT protocols on exercise performance, metabolic adaptation, and fat loss in middle-aged and older adults with overweight.
Applicability of a supramaximal high-intensity interval training program for older adults previously not engaged in regular exercise; analyses of secondary outcomes from the Umeå HIT Study.
The intensity paradox: A systematic review and meta-analysis of its impact on the cardiorespiratory fitness of older adults.
Effects of Controlled Supramaximal High-Intensity Interval Training on Cardiorespiratory Fitness and Global Cognitive Function in Older Adults: The Umeå HIT Study-A Randomized Controlled Trial.
Aerobically trained older adults show impaired resting, but preserved exercise-induced circulating progenitor cell count, which was not improved by sprint interval training.
About this collection: scope and limitations
Practice or procedure · Practices and procedures can differ by protocol and setting. An observed association is not automatically an intervention effect or a longevity benefit.
Questions to check in the original studies
- What activity or procedure did the original source investigate?
- Which population, setting, comparison and follow-up were described?
- Was the activity studied as an intervention or recorded as an observational exposure?
What the displayed selection contains
17 research metadata records and 7 trial registrations were returned in the initial selection. More records can be loaded above. This is not a complete worldwide evidence review. These counts do not measure benefit, safety or evidence certainty.
Interpretation remains unassessed
Open the original sources to assess study design, findings and applicability. A trial registration is not a result; a metadata mention is not a scientific conclusion. Missing matches do not establish that research is absent.
Index snapshot: . This is the index projection timestamp, not the date of a discovery or expert review.

Matching, coverage and vocabulary provenance
This automated index uses permitted minimal bibliographic metadata and checks current source and record eligibility. Literal title or controlled-term matches are discovery relationships, not scientific findings. Retained metadata coverage is bounded; historical completeness of external sources is not certified.
Foods, preparations, extracts and compounds retain distinct identities. Ambiguous labels require a choice. Source AI processing, model training and raw redistribution are disabled for this search.
