Investigating the Effects of Aerobic and Resistance Training in Vivo on Skeletal Muscle Metabolism in Vitro in Primary Human Muscle Cells (MoTrMyo)

Subjects will be asked if an additional biopsy from an existing incision can be obtained (i.e. additional needle insertion). For each biopsy required in the main MoTrPAC study (NCT03960827), a small needle will be used to inject some numbing medication (similar to what a dentist uses) in your thigh. A small incision (about 1/4 inch) will be made and a special needle will be used to collect 1 or 2 muscle samples (about the size of a pea).
