Can you rebuild wasted muscle

Physiologic atrophy is a condition that can be reversed. The rebuilding of muscles takes time, as well. The most effective methods for reversing atrophy are the same as those used to prevent atrophy—staying active, physical therapy, passive movements, and maintaining adequate nutrition.

Once you feel ready to become active again, the muscle weakness of atrophy combined with the weakness of your illness can be a challenging hurdle. Keeping your expectations reasonable and planning on making gradual improvement can help keep you from getting discouraged. Rehabilitation is an important part of recovery, and you should be sure to take advantage of the resources available to you. Many people living with neurological illness become depressed when they observe their own skinny bodies that appear weak and malnourished.

But it is important to remember that physiologic atrophy can be reversed. It may be hard to stay motivated when it comes to preventing or reversing muscle atrophy. Mild or moderate activities, such as walking a few steps with assistance or even bathing, may seem exhausting, but these activities are an important part of regaining strength and rebuilding muscle.

Cochrane Database Syst Rev. Published Jan Hypertrophy can occur without major increases in strength, but there has also been shown a correlation of increases in strength as well as in the cross-sectional area of muscle 6.

NASM notes, in their personal training program , that strength is the ability of the neuromuscular system to produce internal tension in order to overcome an external load 1. The ability to gain strength can occur without dramatically increasing size. Gaining strength but not size directly relates to changes in the nervous system. This increase is from the coordination of muscles during weight training exercise -- an increase in synchronization, recruitment, and firing of motor units 2.

There are variables that come into play to determine if you are going to gain size or maximal strength. By lifting heavy loads, keeping lower repetitions , having longer rest periods min. If muscle atrophy occurs for individuals that have trained more for strength over size, they will still suffer from the same losses that one would from training for size.

There would be a loss of strength, loss of neuromuscular coordination, a loss of endurance, and an increase in injury risk. For years the urban legend that muscle turns to fat has been on the minds of many. The conversations regarding this concept have reverberated through the rows of exercise machines and the walls of locker rooms. As we dive into the subject of muscle atrophy, many think if you lose muscle that it has to go somewhere, so it must turn into fat.

When muscle atrophy occurs it is most often from lack of activity for an extended period of time. As protein degradation exceeds protein resynthesis your muscles are shrinking and your metabolism is likely requiring less calories to support the muscle. If you are losing muscle and you seem to be increasing body fat, it is most often due to a caloric surplus from not moving as much and consuming too many calories.

This shift seems to be why people have assumed that muscle turns to fat. By not regularly strength training and not having a proper nutrition plan in place for hypertrophy , there is a much greater chance of body fat increasing. The concept of bare minimum work to maintain size and strength is challenging because of how complex our bodies truly are. The problem that happens is that we do not live in the perfect scenario to keep ourselves in a maintenance phase.

Many factors become challenges. This includes hitting a plateau, meaning if your body is no longer receiving the increased stimulus it once received from your workouts, you may not experience the same benefits you once did. If stress has increased in your life, cortisol levels may hinder your ability to maintain your strength and size.

If sleep is compromised, this could also impact your progress. Knowing the bare minimum to maintain strength is good, but do not lose site that fitness programs need to progress, typically every 4 to 8 weeks.

Another consideration is to also know your numbers in other aspects of fitness and health. Know your 1 repetition max 1 RM for various exercises, your VO 2 score for cardio and your body fat percentage as well. If you have access to metabolic testing and blood panels, these are also important to know. Being proactive is key to keeping your size and strength. Studies have shown that within a week there are molecular signs of atrophy. You may have an undiagnosed condition that requires treatment.

But even after it begins, this type of atrophy can often be reversed with exercise and improved nutrition. Astronauts, for example, can experience muscle atrophy after a few days of weightlessness. Some medical conditions can cause muscles to waste away or can make movement difficult, leading to muscle atrophy.

These include:. If muscle atrophy is caused by another condition, you may need to undergo testing to diagnose the condition. Your doctor may also order tests to help with the diagnosis and to rule out certain diseases. These tests may include:. Treatment will depend on your diagnosis and the severity of your muscle loss. Any underlying medical conditions must be addressed.

Common treatments for muscle atrophy include:. Physical therapists can teach you the correct ways to exercise. They can also move your arms and legs for you if you have trouble moving. If your tendons, ligaments, skin, or muscles are too tight and prevent you from moving, surgery may be necessary. This condition is called contracture deformity.

Surgery may be able to correct contracture deformity if your muscle atrophy is due to malnutrition. It may also be able to correct your condition if a torn tendon caused your muscle atrophy. If malnutrition is the cause of muscle atrophy, your doctor may suggest dietary changes or supplements.

Muscle wasting or atrophy is usually caused by not being able to regularly exercise your muscles.
