Skeletal Muscle and Adipose Tissue Responses After Acute Exercise: Comparing Effects of Three Different Intensities

An interventional study of Low intensity exercise session and Moderate intensity exercise session in Cellular Responses Within Skeletal Muscle in Response to Exercise of Different Intensities, Relationship Between the Cellular Responses in Skeletal Muscle and the Changes in the Metabolomic Profile and Changes Within Adipose Tissue in Response to Exercise at the Three Different Intensities, sponsored by University of Michigan. Completed at 1 site in United States. Open to participants aged 18 Years to 40 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2024-07-26.

Study summary

The study will assess the exercise-induced changes in chromatin accessibility and gene expression in a cell type-specific manner in skeletal muscle from healthy adults in response to exercise at three different intensities - 1) low-intensity continuous exercise, 2) moderate-intensity continuous exercise, and 3) high-intensity interval exercise.
