Muscle retention is an important topic for anyone interested in health and fitness. It refers to the ability to maintain muscle volume and strength, which is crucial for overall health, mobility, and independence. With age, muscle loss occurs naturally due to hormonal changes and decreased protein synthesis, but it can be accelerated by inactivity, poor diet, and certain diseases. Maximizing muscle retention involves a combination of progressive resistance training, adequate protein intake, and sufficient sleep.

Muscular dystrophy and myopathies
Muscle retention refers to the ability to build and maintain muscle mass. Progressive resistance training (PRT) is considered the best method for building muscle mass, regardless of age. In PRT, the workout volume is gradually increased as strength and endurance improve, challenging the muscles and preventing plateaus. A sufficient protein intake, particularly from animal sources, is also crucial for muscle retention.
Muscular dystrophy (MD) is a group of inherited genetic diseases that cause progressive weakness and degeneration of skeletal muscles, resulting in the wasting away of muscle tissue. There are over 30 types of MD, which vary in terms of the muscles affected, age of onset, and rate of progression. While some types of MD have a specific feature or area of the body that they affect, others are defined by these factors. For example, distal MD primarily affects the distal muscles in the forearms, hands, lower legs, and feet, while myotonic MD is characterised by an inability to relax muscles following contractions.
MD can affect people of all ages, races, and sexes, although the most common type, Duchenne MD, usually occurs in young boys. The main sign of MD is progressive muscle weakness, which can lead to difficulty walking, using arms, and performing daily activities. Some individuals with MD may also experience breathing problems and require a ventilator. While there is no cure for MD, medications and therapy can help manage symptoms and slow the course of the disease.
Myopathies are neuromuscular disorders that affect the nerves, muscles, or the neuromuscular junction. Inflammatory myopathy is a specific type of myopathy that produces symptoms similar to MD, such as progressive muscle weakness. However, it is caused by different genetic defects. While MD is typically inherited, myopathies can also be acquired due to various factors, including autoimmune diseases, infections, and drug side effects.

Neurogenic atrophy
Muscle atrophy is the wasting or thinning of muscle mass. It can be caused by muscle disuse or neurogenic conditions. Disuse atrophy occurs when muscles are not used enough, and neurogenic atrophy occurs due to nerve problems or diseases.
Diseases and conditions that can affect these nerves include:
- Amyotrophic lateral sclerosis (ALS)
- Guillain-Barre syndrome
- Carpal tunnel syndrome
- Spinal cord injury
- Multiple sclerosis
The diagnosis of neurogenic atrophy involves a physical examination, reviewing symptoms, and specific tests. These tests may include blood tests, muscle or nerve biopsies, electromyography (EMG), nerve conduction studies, computed tomography (CT) scans, and magnetic resonance imaging (MRI) scans.
Unfortunately, neurogenic atrophy typically cannot be reversed due to the physical damage to the nerves. However, treatment options may include physical therapy, ultrasound therapy, and, in some cases, surgery to correct contractures.
To summarise, neurogenic atrophy is a severe form of muscle atrophy caused by nerve issues or diseases. It results in muscle wasting and thinning due to the body's breakdown of unused muscles. This condition is challenging to reverse and often requires specialised treatments.

Sarcopenia
The pathologic changes associated with sarcopenia include a reduction in muscle tissue quality, an increase in fibrosis, changes in muscle metabolism, oxidative stress, and degeneration of the neuromuscular junction. The hallmark sign of sarcopenia is the loss of lean muscle mass, specifically in the anterior thigh and abdominal muscles. This change in body composition may be difficult to detect due to obesity, changes in fat mass, or edema. Other signs and symptoms of sarcopenia include muscle weakness, loss of stamina, difficulty performing daily activities, walking slowly, trouble climbing stairs, poor balance, and an increased risk of falls and fractures.
The degree of sarcopenia is determined by two factors: the initial amount of muscle mass and the rate at which muscle mass declines. Immobility dramatically increases the rate of muscle loss, even in younger individuals. Other factors that can increase the progression of sarcopenia include decreased nutrient intake, low physical activity, and chronic diseases such as chronic obstructive pulmonary disease (COPD), chronic heart failure (CHF), chronic kidney disease (CKD), diabetes mellitus, human immunodeficiency virus (HIV), and cancer.
The diagnosis of sarcopenia is based on decreased levels of muscle strength, muscle quantity or quality, and physical performance. Multiple diagnostic criteria have been proposed, and the condition was assigned an ICD-10 code in 2016, recognising it as a disease state. The European Working Group on Sarcopenia in Older People (EWGSOP) developed a broad clinical definition for sarcopenia, characterised by the presence of low muscle mass and either low muscular strength or low physical performance. Hand grip strength has also been advocated as a simple and cost-effective clinical marker of sarcopenia.
While there is no consensus on the definition and causes of sarcopenia, adequate nutrition and targeted exercise remain the gold standard for therapy. Progressive resistance training (PRT) and a diet high in protein are recommended to build and preserve muscle mass.

Nutrition and diet
Muscle retention refers to the preservation of muscle mass and strength. This is achieved through a combination of exercise and a healthy diet.
Protein is often referred to as the "king of muscle food." This is because the body breaks down protein into amino acids, which are the building blocks of muscle. Therefore, consuming adequate amounts of high-quality protein is essential for muscle retention. Animal sources such as meat, eggs, and milk are considered ideal due to their complete amino acid profiles. However, it is important to choose lean protein sources and avoid red and processed meats, which are high in saturated fat. Instead, opt for lean chicken, salmon, or plant-based proteins like tofu and beans.
The recommended daily protein intake varies depending on age, gender, and activity level. For older adults engaging in resistance training, a recent study suggests a daily intake of 1 to 1.3 grams of protein per kilogram of body weight. For example, a 175-pound man may require about 79 to 103 grams of protein per day. Spreading this intake across meals can maximize muscle protein synthesis.
In addition to protein, consuming adequate amounts of healthy fats is crucial for muscle retention. Unsaturated fats, particularly omega-3 and omega-6 fatty acids, play a vital role in supporting overall health and muscle-building processes. These fats support testosterone production, the immune system, and the thyroid gland, which regulates metabolism. Good sources of omega-3 and omega-6 fatty acids include walnuts, extra virgin olive oil, flax seed oil, cold-water fish like salmon, and omega-3 enriched eggs. It is recommended to spread fat intake across meals to avoid a sudden rush of fatty acids, which can be hard on the digestive tract.
Carbohydrates are another important macronutrient to consider in a muscle retention diet. Consuming a carbohydrate-to-protein ratio of about 3:1 or 4:1 within 30 minutes after a workout can maximize muscle growth and improve recovery. For example, chocolate milk, which contains carbohydrates and protein, is a good choice for post-workout recovery.
Finally, it is important to remember that muscle retention is a long-term process that requires a consistent and balanced approach to nutrition and exercise. While supplements can be part of a muscle retention strategy, they should always be used as recommended and in conjunction with a healthy diet and exercise program.

Exercise and physical activity
Muscle retention refers to the preservation of muscle mass and strength. It is important for overall health and can be achieved through exercise and physical activity.
- Progressive Resistance Training (PRT): This involves gradually increasing the intensity of your workouts by increasing weight, reps, and sets as your strength and endurance improve. PRT has been shown to effectively build and preserve muscle mass, particularly in older adults.
- Cardio and Endurance Training: Engaging in cardiovascular exercises and endurance training can also contribute to muscle retention. However, it is important to note that excessive endurance training may lead to muscle damage, so ensure you incorporate rest and recovery periods.
- Daily Movement: Incorporate movement into your daily routine, even when you're not engaging in structured workouts. For example, take the stairs instead of the elevator, or do some light exercises like knee lifts or leg lifts during commercial breaks while watching TV.
- Targeted Muscle Groups: Depending on your specific needs and goals, you can focus on exercises that target particular muscle groups. For example, if you want to improve your leg strength, incorporate exercises like squats, lunges, or calf raises into your routine.
- Safe and Consistent Training: It is important to train safely and consistently. Consult with a qualified professional to design a training program that suits your needs and abilities. Start slowly and gradually increase the intensity to avoid injuries.
Additional Tips:
- Protein Intake: Ensure adequate protein intake, as protein is essential for muscle growth and repair. Animal sources like meat, eggs, and milk provide all the essential amino acids. Older adults may require higher protein intake to compensate for age-related declines in protein synthesis.
- Nutrition Timing: Consume a meal or drink with an appropriate carbohydrate-to-protein ratio (3:1 or 4:1) within 30 minutes after your workout to maximize muscle growth and improve recovery.
- Sleep: Get sufficient sleep, as it plays a vital role in muscle recovery and repair.
- Address Inactivity: Minimize periods of inactivity, especially during illness or injury. Even if you are immobilized, consult a healthcare professional about possible exercises or movements you can safely perform to maintain muscle function.
By incorporating these strategies into your exercise and physical activity routine, you can effectively promote muscle retention and maintain your overall health.

Frequently asked questions
Muscle retention refers to the ability to maintain muscle volume or mass.
Muscle retention is important for health and performance reasons. More muscle generally means more force input to your skeletal system, which increases bone density and reduces the risk of osteopenia and osteoporosis.
The key strategies for muscle retention are nutritional and exercise-based. Nutritional strategies include consuming enough protein, ideally including meat and dairy, and matching your daily calories with your carbohydrate intake, particularly around training time. Exercise-based strategies include progressive resistance training (PRT), which involves gradually increasing workout volume as strength and endurance improve.
Muscle loss, or atrophy, can be caused by immobility, aging, malnutrition, medications, or a wide range of injuries or diseases that impact the musculoskeletal or nervous system. Aging is the primary driver of muscle loss, but it can be accelerated by a lack of exercise and poor eating habits.
