Muscle memory.
If ever you've had a lengthy period of time away from the gym and noticed that your muscle size and strength have returned more quickly than you would've thought then you may have experienced the benefits of muscle memory.
According to Dr. Bhumesh Tyagi, Senior Consultant of General Medicine, Sharda Hospital say that after taking a break muscles that have been trained earlier can start to increase in strength and size more rapidly which is a fascinating biological phenomenon known as 'muscle memory'. Although many people think of muscle memory in connection with learning how to ride a bicycle or how to play a sport it has been discovered that muscle memory can actually be a type of memory held by the actual muscles themselves which can help aid in future muscle growth.
Muscle memory is the term used to describe the body's ability to pick up on physical skills or to re-create muscle tissue that was previously formed by exercise. A study titled 'Myonuclear Permanence In Skeletal Muscle Memory' published in the National Institute of Health (NIH) indicates that strength training stimulates muscle growth in which muscle fibres gain additional nuclei or myonuclei. These nuclei are important for muscle protein synthesis and muscle growth. Interestingly a team of scientists claim that many of these myonuclei may remain in the muscle even when muscle size decreases due to inactivity. This means that when a person returns to training the muscles can recover more efficiently than during the first training period.
The greatest benefit of muscle memory is quicker muscle recovery following breaks. "Some people discontinue exercise due to an injury, illness, pregnancy, work or lifestyle changes previously trained muscles often regain their size and strength more quickly," Dr. Tyagi explained. "It's thought to be due to the fact that the muscle cells have already been adapted from previous training. These myonuclei may aid in the production of proteins more rapidly helping the muscles in responding better to resistance training."
Fascinating data says 'muscle memory' works in both positive and negative ways. It recalls hard work and how to perform it most efficiently, but frequent/prolonged periods of injury/downtime (leading to muscle atrophy) prime your muscles for greater atrophy next time around. https://t.co/ALYycTmPku

Muscle size and strength can decrease over time but muscle memory can last for years. Studies indicate that the loss of mass is possible but some cellular adaptations acquired during training can be retained by facilitating rapid adaptation to the exercise when returning to it. But the amount of muscle regained will vary based on a number of factors such as age, overall health, diet, length of the layoff and the intensity of training.
The expert says that after a rest period it is better to gradually resume exercise than to try to exercise the same weight as before the rest period. Focus on progressive overload, proper form and adequate recovery. Protein is also important for a balanced diet and muscle repair and development. Foods such as eggs, lean meat, fish, dairy products, legumes and nuts can help meet daily protein requirements.
Your muscle memory is one of the greatest adaptations to exercise. Although muscle loss can occur during a period of inactivity it will have cellular adaptations from previous training that promote reacquisition of muscle size and strength more rapidly. With regular exercise, healthy eating and recovery muscle memory can help the process of regaining fitness to be less daunting and more effective than a fresh start.
