Muscle atrophy is a condition that can affect anyone, especially those with spinal cord injuries, MS, or other medical conditions. It is characterized by a decrease in muscle mass and strength, which can severely impact an individual's movement and mobility. The condition can be caused by various factors, including inactivity, ageing, malnutrition, genetics, and certain medical conditions. While there is currently no cure for skeletal muscle atrophy due to the complex nature of the condition, there are strategies to control and mitigate further atrophy and help individuals maintain their strength.

Exercise regularly, focusing on resistance training, weightlifting, and stair climbing
Exercise is a common treatment for muscle atrophy. Physiologic atrophy, which is caused by not using muscles enough, can be reversed with exercise and a healthy diet. To prevent muscle atrophy, it is important to exercise regularly, focusing on resistance training, weightlifting, and stair climbing.
Resistance training strengthens and maintains the major muscle groups. It can be done anywhere, with or without weights and resistance bands. The Physical Activity Guidelines for Americans recommend strength training two to three times a week to the point of difficulty in performing another repetition. Free weights are a preferred method and can be used anywhere. When using weights or resistance bands, it is crucial to select the proper weight to improve strength and prevent injury. One can set a target of eight to twelve repetitions and gradually work up to two to three sets. For those who prefer equipment-free training, exercises like push-ups, squats, planks, hip lifts, and dips can be done using one's own body weight. Yoga is another option that builds muscle while improving flexibility and reducing stress.
Weightlifting is another effective way to prevent muscle atrophy. Scott Haak, a member of the Mayo Clinic staff and an exercise enthusiast, enjoys weightlifting and sports performance training. He is also a Certified USA Weightlifting Coach.
Stair climbing is an easy and effective way to build muscle power, especially for older adults. A study found that climbing two flights of stairs a few times twice a week for 12 weeks led to gains in muscle power and functionality. It is an accessible, at-home workout that does not require a gym membership. To increase the challenge, one can skip a step while climbing the stairs or add extra weight to a backpack.

Ensure adequate caloric intake to prevent muscle fibres from breaking down
Ensuring adequate caloric intake is crucial to preventing muscle fibres from breaking down and reducing muscle mass. When the body experiences a calorie deficit, it enters a state of catabolism, breaking down muscle tissue for energy, which leads to muscle atrophy. Thus, it is essential to avoid a significant calorie deficit and provide your body with sufficient calories to prevent muscle breakdown.
Maintaining a balanced diet with adequate protein intake is vital to preventing muscle atrophy. Proteins provide essential amino acids, which promote muscle growth and repair. By consuming enough protein, you create favourable conditions that encourage muscle growth and protect against muscle loss. Aim for a protein intake of 1.25–1.5 times the RDA if you lead a sedentary lifestyle, and over 1.5 times the RDA if you engage in regular physical activity.
In addition to protein, include a variety of nutrients in your diet to give your body all the tools it needs to build and maintain muscle mass. A well-rounded diet ensures that your body receives the full spectrum of nutrients required for muscle health. Stay hydrated by drinking plenty of water, as this helps flush out toxins and keeps your muscles properly hydrated, reducing the risk of cramping or pain due to dehydration.
While calorie intake is important, it is equally crucial to avoid overeating or consuming excess calories. Focus on healthy eating habits and making sustainable lifestyle changes. This includes eating a balanced diet rich in protein and other essential nutrients, as well as staying hydrated. By prioritising a healthy and balanced diet, you can effectively prevent muscle fibres from breaking down and maintain overall muscle health.

Eat a diet rich in protein to promote muscle growth and repair
Muscle atrophy is a condition that can affect anyone, especially those with spinal cord injuries or MS. It is characterized by a reduction in muscle mass and strength, which can impact movement and mobility. The condition can be caused by various factors, including inactivity, malnutrition, age, genetics, and certain medical conditions.
To minimize muscle atrophy, it is crucial to focus on your diet and incorporate high amounts of protein-rich foods. Protein is essential for muscle growth and repair, as it provides the body with amino acids, which are the building blocks of muscle tissue. By consuming adequate protein, you can promote muscle growth and prevent muscle loss. According to the Dietary Guidelines for Americans 2020-2025, adult women should consume at least 46 grams of protein per day, while adult men should aim for 56 grams. However, these amounts are minimum recommendations to prevent protein deficiency, and some individuals may benefit from higher protein intakes. For example, older individuals above 65 years of age may require 1.2 to 1.59 grams of protein per kilogram of body weight to support muscle growth.
Protein-rich foods come from both animal and plant sources. Animal sources of protein include eggs, chicken, salmon, Greek yogurt, skim milk, and dairy protein powders such as whey and casein. Plant-based sources of protein include chickpeas, peanuts, soybeans (edamame), and buckwheat. It is important to note that while plant sources offer protein, their quality may be lower than that of animal sources. Nonetheless, they can still be part of a balanced muscle-building diet.
In addition to protein, it is crucial to consume a well-balanced diet that includes healthy carbohydrates and fats. Carbohydrates and fats provide the fuel needed for exercise and physical activity, which is essential for muscle growth and maintenance. They also contribute to overall calorie intake, ensuring that you are not in a calorie deficit, which can lead to muscle loss.
By focusing on a diet rich in protein, along with adequate carbohydrates and fats, you can promote muscle growth and repair, helping to minimize muscle atrophy.

Consult a doctor for a physical exam, blood tests, and nerve conduction studies
Consulting a doctor is crucial for an accurate diagnosis and tailored treatment plan to minimize muscle atrophy. During a physical exam, your healthcare provider will visually assess your muscles, focusing on your arms and legs, and measure your muscle mass. They will also inquire about your symptoms, including any weakness, numbness, or tingling sensations in your limbs. This information aids in understanding the extent and potential causes of your muscle atrophy.
Blood tests are an essential component of the diagnostic process for muscle atrophy. These tests can provide valuable insights into your overall health and help identify any underlying medical conditions that may be contributing to the atrophy. For example, blood tests can check for nutritional deficiencies or inflammation markers, which could indicate certain medical conditions. Additionally, blood tests can assess muscle enzyme levels, which, if elevated, may suggest muscle damage or breakdown.
Nerve conduction studies are a specialized type of diagnostic test used to evaluate the health and function of the nerves that control your muscles. These studies involve stimulating your nerves with mild electrical impulses to measure their ability to transmit signals to your muscles. Nerve conduction studies are particularly relevant in cases of suspected neurogenic atrophy, where nerve problems or diseases lead to muscle atrophy. By understanding the extent of nerve damage and its impact on muscle function, healthcare providers can develop more targeted treatment plans.
In addition to the physical exam, blood tests, and nerve conduction studies, your doctor may also recommend further tests, such as muscle or nerve biopsies, electromyography (EMG), computed tomography (CT) scans, or magnetic resonance imaging (MRI) scans. These additional tests can provide more detailed information about the severity and specific causes of your muscle atrophy, helping guide the most effective treatment strategies to minimize its impact on your health and quality of life.
