Overview
Brief 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.
