What was done
This paper details the design and protocol for the human component of the Molecular Transducers of Physical Activity Consortium (MoTrPAC). Sedentary adults are randomized to 12 weeks of Control, Endurance Exercise Training, or Resistance Exercise Training with baseline and post-intervention phenotyping, alongside a cross-sectional comparison group of highly active endurance- or resistance-trained adults assessed once. A parallel pediatric component evaluates endurance exercise only. Phenotyping includes body composition, vital signs, cardiorespiratory fitness, muscular strength, questionnaires, and biospecimen collection around acute exercise bouts or rest (blood-only for pediatric participants).
What was found
The abstract reports protocol specifications and study methodology only; no participant numbers, effect estimates, or empirical outcome data are reported.
Why it matters
MoTrPAC establishes a large-scale, standardized multicenter protocol to map the molecular responses to acute and chronic exercise, creating a shared data repository to inform precision exercise medicine.
Limits
As a protocol paper, no clinical or molecular findings are provided. The abstract omits target sample sizes, specific non-blood biospecimens collected in adults, and trial feasibility metrics such as adherence and dropout.
