Maintaining muscle health is important for people of all ages, as it can help prevent injury, aid recovery, and improve overall health. One way to promote muscle health is through strength training, also known as resistance or weight training, which involves exercises like lifting weights, squats, and lunges. For older adults, strength training can help maintain functional independence and improve everyday movements. It is recommended that adults participate in at least 150 minutes of moderate-intensity or 75 minutes of vigorous-intensity strength training each week. In addition to strength training, eating a balanced and nutrient-rich diet is crucial for muscle health, with protein intake being especially important. Consuming protein during or after exercise can help stimulate muscle protein synthesis and promote muscle growth. While supplements may also support muscle growth, a well-rounded diet and consistent exercise routine are the most important factors in maintaining and improving muscle health.

What You'll Learn
Weight training
To begin weight training, it is recommended to start with light weights and gradually increase the weight and resistance level. It is important to perform all exercises with the correct form, breathing techniques, and controlled movement to reduce the risk of injury and enhance muscle building. Consistency is key when it comes to weight training, and it is beneficial to incorporate it into your routine at least two days a week.
In addition to weight training, protein intake is essential for muscle growth. Current guidelines suggest that adult males and females consume 56 grams and 46 grams of protein daily, respectively. Consuming protein during or immediately after exercise stimulates muscle protein synthesis and promotes more effective muscle reconditioning. It is also beneficial to eat small servings of protein-rich foods before and after each resistance training session to promote muscle growth.
Remember, it is important to consult with a doctor or a fitness professional before starting a new exercise regimen to ensure it is safe and appropriate for you.

Cardiovascular exercise
Aerobic exercise improves circulation, which results in lower blood pressure and a reduced heart rate. It also boosts the amount of blood circulating through the body, encouraging blood vessels to become more flexible over time. This type of exercise includes activities such as jogging, swimming, and cycling. The American College of Sports Medicine recommends at least 30 minutes of aerobic exercise five days a week.
Resistance training, on the other hand, helps reduce fat and create leaner muscle mass. It can be done using free weights, weight machines, resistance bands, or body-resistance exercises like push-ups, squats, and chin-ups. The American College of Sports Medicine suggests resistance training on at least two non-consecutive days per week.
Combining these two types of exercise produces the greatest benefit for preventing and managing heart disease. They also burn calories and help improve your baseline metabolic rate, leading to weight loss when coupled with a healthy diet.
It is important to note that cardiovascular exercise can be started with just 10 to 15 minutes of brisk walking per day, gradually increasing the time and intensity. This type of exercise improves overall well-being and longevity, strengthens the heart, increases lung capacity, and enhances the body's ability to utilize oxygen efficiently.

Protein-rich diet
A protein-rich diet is essential for muscle health. Dietary protein is a primary nutrient for the remodelling of muscle tissue, as it can independently stimulate muscle protein synthesis. Current guidelines recommend that adult males and females consume 56 grams and 46 grams of protein every day, respectively.
Protein-rich, whole foods are critical to maintaining muscle health. It is important to note that the distribution of protein intake throughout the day may be more important than the overall amount consumed. Research suggests that consuming 20 grams of dietary protein during or immediately after exercise helps stimulate muscle protein synthesis, reduce protein breakdown, and promote more effective muscle reconditioning. Therefore, it is recommended to eat small servings of protein-rich foods before and after each resistance training session to help promote muscle growth.
Protein-rich foods can include animal sources such as meat, poultry, fish, eggs, and dairy, as well as plant-based sources like beans, legumes, nuts, and seeds. For example, 100 grams of chicken breast provides about 31 grams of protein, while 100 grams of cooked lentils provide about 9 grams of protein. It is important to vary your protein sources to ensure a diverse range of amino acids, which are the building blocks of muscle tissue.
In addition to whole foods, protein supplements can also support muscle growth when paired with a well-rounded diet and regular exercise. Creatine, for instance, is a popular supplement that has been shown to improve strength, exercise performance, and muscle size, particularly in females. However, it is always recommended to consult with a healthcare professional before starting any new supplement regimen to ensure its safety and suitability for your individual needs.
While a protein-rich diet is crucial for muscle health, it is important to remember that overall caloric intake and nutrient density also play a role. Simply increasing protein intake without considering other nutrients can lead to an imbalanced diet. Therefore, it is essential to focus on nutrient-dense foods and ensure adequate caloric intake to support muscle growth and overall health.

Supplements
Creatine
Creatine is an amino acid that occurs naturally in the body and is also found in foods like red meat and fish. It is one of the most widely studied and used supplements for improving exercise performance and increasing muscle strength and mass. Creatine helps supply muscles with energy, allowing you to perform more reps during workouts and gain strength over time. The typical dosage is 20 grams daily for the first 5-7 days, followed by 3-5 grams daily for up to 12 weeks. However, it is always recommended to consult a doctor before starting any new supplement regimen.
Whey Protein
Whey protein is a fast-digesting protein found in milk that contains essential amino acids necessary for muscle growth. Consuming whey protein consistently alongside an exercise routine can improve strength and muscle growth. Whey protein is available in various forms, including powders, bars, and shakes, making it a convenient way to increase your protein intake. The typical dosage is around 20-30 grams per scoop or serving. However, it is important to note that whey protein may cause side effects such as bloating, diarrhea, thirst, and nausea in some individuals.
Branched-Chain Amino Acids (BCAAs)
BCAAs include leucine, isoleucine, and valine, which are essential amino acids that provide energy to skeletal muscle cells during exercise. They can help delay muscle fatigue and improve exercise performance, leading to better muscle gains over time. BCAAs can be consumed through protein-rich foods or taken as supplements.
Carnitine
Carnitine is a compound produced naturally in the brain, liver, and kidneys, and it can also be found in red meats, fish, and certain plants. While it may not be as effective for muscle mass increase in young or middle-aged active individuals, studies suggest that carnitine may have benefits for muscle growth and recovery in older adults. The typical dosage ranges from 1-4 grams daily for up to a year. However, some side effects to be aware of include stomach cramps, nausea, diarrhea, and a fish-like odour.
Collagen
Collagen is the most abundant protein in the body and is rich in amino acids like L-arginine and glycine. It plays a crucial role in skin health and protecting against sports injuries. Research indicates that collagen supplements, when paired with exercise, may enhance strength, muscle recovery, and body composition, especially in older males experiencing age-related muscle loss (sarcopenia).

Rest and recovery
After strength training, your muscles undergo repair processes that lead to muscle growth. This growth occurs during rest periods, making them a critical part of your muscle-building routine. Aim to give your muscles at least one day to rest between strength training sessions. For example, if you work out on Monday, the next session should be on Wednesday at the earliest.
Additionally, getting sufficient sleep is vital for muscle recovery. Aim for seven to nine hours of quality sleep each night. During sleep, your body produces growth hormone (GH), which is crucial for muscle repair and growth. Also, drinking plenty of water and consuming a balanced diet rich in protein and carbohydrates will support your body's recovery process.
Remember, the recovery process is when your muscles rebuild and grow stronger. By allowing adequate recovery time and following the above recommendations, you'll optimise your body's ability to repair and build muscle.
