There are many ways to unintentionally weaken your muscles. Muscle atrophy, or muscle weakness, can occur due to a variety of factors, including lack of physical activity, ageing, injury, and certain medical conditions. Leading a sedentary lifestyle, having a desk job, or not getting enough exercise can all contribute to muscle atrophy. Additionally, certain diseases and chronic conditions, such as muscular dystrophy, multiple sclerosis, and arthritis, can lead to muscle weakness. In some cases, muscle weakness may be a side effect of certain medications or lifestyle choices, such as prolonged alcohol use or smoking. Understanding the causes of muscle weakness is important to take preventive measures and maintain overall health and well-being.
Characteristics and Values of unintentionally weakening muscles
| Characteristics | Values |
|---|---|
| Muscle atrophy | Loss or thinning of muscle tissue, decrease in muscle mass and strength, smaller muscles |
| Causes of muscle atrophy | Malnutrition, age, genetics, lack of physical activity, medical conditions, nerve problems, nerve damage, inactivity, inadequate nutrition |
| Muscle function loss | Failure of nerves to send signals from the brain to the muscles, disease affecting muscles or nervous system, injury, drug overdose, coma |
| Muscle guarding | Body's protective response to an injury, muscles around the injured area tighten up, can lead to restricted mobility and muscle atrophy if it lasts too long |
| Muscle weakness | Lack of exercise, ageing, muscle injury, pregnancy, long-term conditions (e.g. diabetes, heart disease), stroke, multiple sclerosis, depression, chronic fatigue |
| Indirect causes of muscle weakness | Smoking, alcohol consumption, cocaine and other recreational drug use, sleep disorders |

Lack of exercise
The process of muscle atrophy due to inactivity can begin within two to three weeks of immobility. It is often experienced by individuals recovering from an illness or injury, those with desk jobs, or those with genetic disorders that limit mobility. In such cases, the muscles are not being used optimally, and the body adapts by conserving energy and redirecting it away from maintaining muscle mass.
The good news is that muscle atrophy caused by lack of exercise is typically reversible. Engaging in regular exercise and physical therapy can help rebuild muscle strength and size. Working out in water, for instance, can be an effective way to reduce the workload on weakened muscles while still providing the necessary stimulation to promote growth.
In addition to exercise, proper nutrition is crucial in maintaining and regaining muscle strength. Malnutrition can contribute to muscle atrophy, as the body may not receive the necessary nutrients to support muscle health. Adequate protein intake is particularly important, as it provides the building blocks for muscle growth and repair.
While lack of exercise can lead to muscle weakness, it's important to note that muscle atrophy can also occur due to other factors such as age, genetics, and certain medical conditions. Maintaining an active lifestyle and a balanced diet can help mitigate the risk of muscle atrophy and promote overall health.

Ageing
Several factors contribute to sarcopenia and muscle weakness in older individuals:
Inactivity and Disuse
A sedentary lifestyle or lack of physical activity can lead to muscle wastage and is considered a significant contributor to age-related muscle loss. Research suggests that inactivity accounts for at least half of the age-related changes in muscles, bones, and joints. Engaging in regular physical activity and progressive resistance training (PRT) can help prevent and reverse muscle loss. Simple exercises like walking, or resistance exercises such as using resistance bands, can be beneficial.
Nutrition and Diet
Nutrition plays a crucial role in muscle health. Eating styles that are deficient in calories, protein, vitamins, and minerals can result in diminished muscle mass. Ensuring adequate calorie intake and consuming high-quality protein are essential for maintaining and improving muscle mass. Omega-3 fatty acids, found in seafood or supplements, can promote muscle growth at any age. Additionally, consuming a meal or drink with the appropriate carbohydrate-to-protein ratio after a workout can maximise muscle growth and improve recovery.
Hormonal Changes
Age-related hormonal changes can impact muscle health. In women, menopause triggers a loss of minerals in bone tissue, affecting muscle strength and coordination. In men, the gradual decline in sex hormones can lead to the development of osteoporosis, which weakens bones.
Biological Mechanisms
Research has identified a biological mechanism behind age-related muscle loss, specifically the leakage of calcium from ryanodine receptors in muscle cells. This leakage impairs the ability of muscle fibres to contract effectively, contributing to muscle weakness.
Other Factors
Other factors that can influence muscle health include endocrine and nutritional changes, insulin resistance, and responsiveness to hormonal stimuli. Additionally, certain conditions like osteoarthritis and osteoporosis can affect joint movement, causing pain and stiffness.

Inactivity due to illness or injury
Illness or injury can lead to a period of inactivity, which can cause muscle weakness and atrophy. Muscle atrophy is the loss or thinning of muscle tissue, resulting in decreased muscle mass and strength. It can occur within two to three weeks of muscle disuse and affects younger and older people differently. Younger people may lose up to a third of their muscle strength in two weeks, while older people lose about a quarter.
During inactivity, the body stops sending signals to the unused muscles, causing them to decrease in size and strength. This is because the body no longer needs to waste energy taking care of those muscles and starts to break them down. This type of atrophy is called disuse (physiologic) atrophy and can be reversed through regular exercise and physical therapy. However, it can take three times the amount of inactivity period to regain the lost muscle mass. Weight training and high-intensity exercises are recommended to restore muscle strength.
Inactivity can also lead to chronic pain, especially in older adults. It increases the weight load on the spine, causing spine pain. Additionally, the lack of movement reduces joint health, leading to joint pain and stiffness. Inactivity weakens the heart, the body's most critical muscle, affecting its ability to pump blood efficiently. It also increases the risk of developing diseases like osteoporosis, type 2 diabetes, high blood pressure, and heart disease.

Malnutrition
Muscle atrophy, or the loss or thinning of muscle tissue, can be caused by malnutrition. Malnutrition may be a risk factor for developing low muscle mass, and it is associated with adverse outcomes. Malnutrition-related muscle atrophy may be the result of medical conditions that impair the body's ability to absorb nutrients.
To diagnose muscle atrophy, a healthcare provider will perform a physical exam and may order tests such as a blood test, muscle or nerve biopsy, or an MRI scan. Treatment for muscle atrophy caused by malnutrition may include nutritional interventions, such as energy- and protein-rich meals, supplementation, or tube feeding.

Nerve damage
Diseases that damage motor neurons, such as amyotrophic lateral sclerosis (ALS), can result in nerve damage that worsens over time. Spinal cord injuries can also interrupt nerve signals to the muscles, leading to muscle weakness. Additionally, conditions like multiple sclerosis (MS) and myasthenia gravis involve the immune system attacking and damaging nerves, which can affect movement and muscle strength.
Substance use can also unintentionally cause nerve damage. Chronic alcohol consumption is a common cause of nerve pain and damage. Toxic substances accidentally ingested, such as lead, arsenic, or mercury, can also damage nerves. Certain medications, such as some chemotherapies and drugs used to treat HIV, may have nerve damage as a side effect.
Nerve pain and muscle weakness can be managed through various treatments, including physical therapy, medication, and surgery. Doctors often prescribe a combination of treatments to improve pain and prevent lasting damage. Mild nerve pain may be managed at home with stretching, heat, over-the-counter pain relievers, and dietary supplements.
