What type of muscle fibers atrophy faster?
For example, muscle disuse, such as spinal cord injury, causes type 1 fiber atrophy with a slow-to-fast fiber type shift, whereas cancer cachexia leads to preferential atrophy of type 2 fibers with a fast-to-slow fiber type shift.
How quickly do muscles start to atrophy?
Some research suggests that you can start to lose muscle in as quickly as one week of inactivity – as much as 2 pounds if you are fully immobilized (3). And another study suggests your muscle size can decrease by about 11\% after ten days without exercise, even when you aren’t bed ridden (4).

Fast Twitch Muscle Fiber Types. The two types of skeletal muscle fibers are slow-twitch (type I) and fast-twitch (type II). Slow-twitch muscle fibers support long distance endurance activities like marathon running, while fast-twitch muscle fibers support quick, powerful movements such as sprinting or weightlifting.
