Key findings

What ClinicalTrials.gov does not surface for Physical Activity on its own pages , computed from the registry mirror as of 2026-08-08. Each line carries its own denominator so it can be quoted as it stands.

  1. Physical Activity is recruiting below its size-band peers.

    45 of 132 indexed trials (34.1%) are open to enrollment, against a 37.1% average across 139 conditions with 100+ trials. The peer set uses the same ClinicalTrials.gov-derived counts as this page.

  2. Sponsorship of Physical Activity trials is spread across many organizations.

    Arizona State University accounts for 5 of 132 trials (3.8%). 85 distinct sponsors appear on at least one study for this condition label.

  3. Typical Physical Activity enrolment sits around 100 participants.

    Median target enrolment is 100 among the 132 trials that report a genuine target (sentinel values excluded). 66 of those (50%) plan for fewer than 100 participants.

  4. Physical Activity research is mostly interventional.

    123 interventional and 9 observational studies make up this index (93.2% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
