Study Details

Study Description

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.

Arms and Interventions

Arm Intervention/Treatment
Experimental: low-intensity continuous exercise

subjects will exercise at 30% maximal oxygen consumption (VO2max) for 45-60 minutes

Behavioral: Low intensity exercise session
subjects will exercise at 30% maximal oxygen consumption (VO2max) for 45-60 minutes

Experimental: moderate-intensity continuous exercise

subjects will exercise at 65% maximal oxygen consumption (VO2max) for 30-45 minutes

Behavioral: Moderate intensity exercise session
subjects will exercise at 65% maximal oxygen consumption (VO2max) for 30-45 minutes

Experimental: high-intensity interval exercise

subjects will completed 10x1minute exercise intervals at maximal oxygen consumption (VO2max) with 1 minute active recovery between

Behavioral: High intensity exercise session
subjects will completed 10x1minute exercise intervals at maximal oxygen consumption (VO2max) with 1 minute active recovery between
