Single Nuclei Sequencing in Human Skeletal Muscle After Unloading

Participants will perform a 5-day unloading intervention using the ULLS model. Short-length crutches, aided by handgrip and forearm support distal to the elbow will be used to assist in any upright or ambulatory activity. One foot (randomized in a counterbalance manner) will be equipped with a shoe having a 10-cm thick sole, which permits the unloaded limb to move passively about the hip joint while adopting a near straight position.
