Maintaining muscle mass is key to staying fit and mobile as we age. Muscle mass typically peaks around 30 to 35 years old and declines steadily after that, with more significant loss in our mid-60s. This loss of muscle strength can make it harder to perform daily activities and increases the risk of severe falls and accidents. However, there are ways to limit this age-related muscle loss, also known as sarcopenia. Leading a healthy lifestyle that includes regular exercise, adequate sleep, and a balanced diet can help to preserve muscle mass and strength.

What You'll Learn
Consume protein-rich foods
Consuming protein-rich foods is essential for maintaining muscle mass. The body breaks down protein-rich foods into amino acids, which are then used to build muscle. Aim to include a variety of protein sources in your diet, such as chicken, turkey, fish, eggs, red meat, yogurt, and beans. These foods provide the body with the necessary building blocks to support muscle growth and repair.
In addition to protein, it is important to consume a balanced diet that includes other key nutrients. For example, omega-3s found in salmon, walnuts, and flaxseeds have anti-inflammatory properties, which can improve muscle protein synthesis. Vitamin D, obtained through sun exposure or supplements, also plays a crucial role in muscle protein synthesis and strength development.
Maintaining adequate hydration is another important aspect of muscle health. Water helps bring nutrients to your muscles and facilitates the removal of waste products. It also impacts muscle contractions and endurance. Be mindful that alcohol consumption can contribute to dehydration and negatively impact your body's ability to absorb nutrients, so it is recommended to limit alcohol intake.
Finally, consider the overall number of calories you consume. To support muscle growth, you should aim for a caloric surplus, ensuring your body has the energy and resources needed to build and maintain muscle mass.

Exercise regularly
Exercise is the most powerful way to stave off muscle loss, especially as we age. It is never too early or too late to start. Even people in their 90s and 100s can still enhance their muscle mass and physical function with the right exercise.
The key to success in muscle maintenance is consistency. Working out two to three times a week, consistently, can help grow muscle tissues and prevent muscle loss. Aim for two to three 30-minute sessions per week. You can start with a small change in activity and add a bit more every day. The most important thing is to commit to staying active.
When strength training, focus on the major muscle groups, such as arms, chest, back, legs, and core. Push-ups are a great exercise, and squats are a compound exercise that works numerous muscle groups. Walking is also a good way to increase mobility and enhance blood flow. Taking 10-minute walking breaks throughout the day can help you maintain muscle mass. Swimming and cycling are other forms of aerobic exercise that can help you stay active.
Weight training and other resistance exercises are excellent ways to maintain strength and muscle mass. They can even positively impact your cardiovascular system. Bone health and muscle health are connected. Weight-bearing exercises make your bones denser and stronger, which is important because if your bones deteriorate, you won't be able to perform the exercises necessary to retain your muscle mass.

Get enough sleep
Sleep is an essential part of muscle recovery. Getting a good night's sleep is crucial for maximising your strengthening routine and muscle recovery. During sleep, the body undergoes several physiological changes that aid in the repair and recovery of damaged tissues.
Research shows that a continuous good sleep quality could help to maintain muscle mass, even if sleep duration is reduced. A good quality of sleep is when you feel refreshed after sleeping. On the other hand, poor sleep quality is when you don't feel satisfied after sleep.
Sleep helps repair and restore muscles, increases muscle strength and mass, and improves athletic performance. During sleep, the body releases the human growth hormone (HGH), which plays a crucial role in muscle repair and growth. HGH stimulates protein synthesis, the process by which damaged muscle fibres are repaired and new muscle tissue is built. Sleep is also important for replenishing muscle glycogen stores, which provide energy for muscle contractions during exercise.
To improve your sleep, aim for 7 to 9 hours of sleep each night, the recommended guideline for healthy adults. Set a consistent sleep schedule by going to bed and waking up at similar times each day. Your body functions more efficiently when it's on a predictable schedule, and this is especially true for sleep.

Manage stress
Stress is a natural human response to situations that feel unmanageable or out of our control. It can affect our mental and physical health, relationships, and ability to complete everyday tasks. Therefore, it is important to manage stress to keep our muscles healthy. Here are some ways to manage stress:
Identify Stressors and Understand Their Impact
Recognize the signs of stress in your life, such as tense muscles, over-tiredness, headaches, irritability, or forgetfulness. Understand the causes of your stress, whether it's one significant issue or a build-up of smaller ones. This awareness will help you take proactive steps to manage it effectively.
Establish Routines and Self-Care Practices
Routines can provide a sense of control and help you manage stress. Establish a daily pattern that includes sleep, healthy eating, and physical activity. Engage in meaningful self-care activities that are relevant to you, such as relaxation, social connections, or enjoying your favorite hobbies. Avoid excessive alcohol and nicotine consumption, as they can contribute to mental health issues.
Engage in Physical Activity and Muscle Relaxation
Regular physical activity, such as walking, jogging, or muscle-strengthening exercises, can help prevent and manage stress while improving your mood. Aim for at least 150 minutes of moderate-intensity aerobic activity per week. Additionally, practice muscle relaxation techniques like progressive muscle relaxation, which involves tightening and slowly releasing muscle groups to reduce tension.
Practice Mindfulness and Deep Breathing
Deep breathing exercises, such as diaphragmatic breathing, can help you relax your muscles and clear your mind. Slow, deep, regular breathing is a sign of relaxation. You can also try mindfulness practices like meditation, holding space, and yoga, which have been shown to reduce stress and promote psychological well-being.
Manage Your Time and Surroundings
Create a to-do list and prioritize tasks to avoid procrastination, which can contribute to stress. Be realistic about deadlines and learn to say "no" to commitments that unnecessarily increase your load. Limit caffeine intake, as it can heighten stress levels, and instead, opt for natural settings and positive physical contact, which have been associated with improved mental well-being.
Remember, stress management is an ongoing process, and it's important to seek support from loved ones or professionals if you need help dealing with stress.

Avoid alcohol and smoking
Alcohol and smoking are detrimental to muscle growth and overall health. Avoiding them is a great step towards keeping your muscles.
Firstly, alcohol affects muscle growth and development. Studies have shown that alcohol interferes with protein synthesis, which is essential for muscle growth. In one study, muscle protein synthesis was reduced by 24% even when alcohol was consumed with 20-30g of protein. Another study found that consuming 1.5g/kg of alcohol after exercise reduced muscle protein synthesis by 37%. Alcohol also lowers testosterone levels, which is a key hormone for muscle growth. Additionally, alcohol increases cortisol levels, which can lead to increased tissue breakdown. It also affects growth hormones, negatively impacting the metabolism of muscles, bones, and the brain.
The effects of alcohol on muscle growth also differ between men and women. Alcohol affects protein synthesis in males more significantly than in females. However, women are more sensitive to the long-term health effects of drinking. Therefore, it is important to drink in moderation, regardless of gender, to support muscle growth and overall health.
Smoking also negatively impacts muscle gains from exercise. Nicotine and carbon monoxide from cigarettes can make your blood "sticky" and narrow your arteries, reducing blood flow to your muscles and making exercise more difficult. Additionally, carbon monoxide bonds with hemoglobin molecules in your blood, reducing oxygen supply to your muscles. Tar from cigarettes accumulates in your airways, further limiting airflow and hindering your lungs' natural cleansing mechanism. As a result, your muscles do not receive the oxygen they need to grow and develop.
Smoking also potentially damages the cells that produce testosterone, leading to lower testosterone levels. Testosterone is crucial for muscle growth and development. By quitting smoking, you can improve your lung capacity and oxygen supply, enhancing your muscles' ability to grow and develop.
In summary, avoiding alcohol and smoking is crucial for maintaining muscle health and supporting muscle growth. Both substances negatively impact the body's ability to build and develop muscle through various mechanisms, including interference with protein synthesis, reduced testosterone levels, and decreased oxygen supply to the muscles. Therefore, it is advisable to limit alcohol consumption and quit smoking to optimize muscle growth and overall health.
