Muscles are like your mind; the more you train and look after them, the stronger they will get, supporting you through daily life. That said, the human body has over 600 muscles!
Can you believe this? Together, these soft tissues make up half of your body weight. While different muscle groups have various tasks to perform in your body, like helping with food digestion, weight maintenance, breathing, and aiding circulation, they're body parts you must look after regularly.
If you don't, your muscles will break down, decreasing size and strength. You'll be at higher risk of symptoms like pain, muscle spasms, muscle weakness and many serious disorders, injuries and diseases.
Dive in with us in this article to learn everything you need to know about your muscles and how to maintain good muscle health.
What are the main types of muscles?
Muscles play a key role in your survival; they're not just used for movement. In every muscle, thousands of elastic fibres are bundled tightly together. A single muscle fibre is made up of blocks of protein called myofibrils. Myofibirs contain a particular type of protein called myoglobin and molecules to provide the oxygen and energy required for muscle contraction.
To understand the main functions of the muscles, it's best to learn the different types of muscles you'll find in your body. The three main types are:
Skeletal Muscle
These muscles are composed of long, cylindrical fibres and have a banded appearance. Skeletal muscles are commonly known as voluntary muscles, as you can consciously control how they move and function. Like their name suggests, they're attached to your bones and help you move, maintain your body posture, store nutrients, stabilise joints and more.
Cardiac Muscle
The cardiac muscle is also called the myocardium, which is a thick middle layer of your heart. This muscle is a thick middle layer in your heart. The main function of this muscle is to help contract your heart and pump blood through the body.
Smooth Muscle
Compared to a skeletal muscle, a smooth muscle is an involuntary muscle and has a spindle shaped cell. You'll find them on the walls of your internal organs like the stomach, intestine, and blood vessels. The main purpose of this muscle is to help transport substances through your organs, e.g. pushing food through your digestive system.
How do muscles function?
Muscles play a role in every system and function of the body. To understand the true function of each muscle group, let's break it down:
Start of the muscle movement
Every muscle movement starts in your brain. Your brain sends an electrical signal to muscles through the nervous system. This is the starting point of muscle contraction. When the signal reaches a muscle, it triggers the release of calcium ions. These ions play a crucial role in muscle contraction.
Muscle contraction process
Muscles are made of fibres. These fibres slide over each other when calcium ions are released. These fibres consist of two main proteins: Action and Moysin. Both function by controlling the voluntary muscular movements within the body, and to move muscles, they need energy. This energy comes from a molecule called Adenosine triphosphate (ATP). ATP provides the necessary power for muscle fibres to slide.
The muscle movement
As the muscle fibres slide over each other, the muscle contracts. This contraction makes the muscles shorter. It's this shortening of muscles that creates muscles to move. After every contraction, muscles relax. This is when calcium ions return to their original place. The muscle fibres then go back to their relaxed state.
What is the impact of exercise on the muscle?
Exercise plays a vital role in muscle health and development. If you engage in physical activity, it will have a profound impact on your muscles, especially in strength training. This intense effort causes small microscopic tears in muscle fibres. Your body then repairs these tiny tears, gradually making your muscles more robust and resilient.
Activities like running, cycling, and swimming focus on muscle endurance. These exercises enhance muscles' ability to work longer without fatigue. However, weightlifting increases muscle mass. Daily exercise helps to tone muscles and improves muscles flexibility and overall strength, giving them a more defined look.
Protein and muscle
Another essential aspect of maintaining good muscle health is your protein intake.
Your protein intake should be between 0.8g-1.8 g x your body weight.
When you consume sufficient protein, it helps repair and build your muscle tissue. Especially after a workout, it's the most important time when protein intake becomes crucial to strengthen your muscle fibres.
However, not only after a workout, but protein is also vital for muscle maintenance and health. Regular protein intake throughout the day is essential. A balanced diet includes a range of protein sources such as meat, dairy, legumes, and plant-based proteins. This ensures your body gets all the essential amino acids for muscle growth and overall health.
4 Ways to aid muscle recovery
To ensure your muscle tissues repair quicker, there are several tasks you can do, such as:
Rest
Your muscle grows and develops when it's resting. Therefore resting after a workout is essential to growth and repair. You should aim to have a full rest day after every 7-10 days. Resting your muscles also reduces the risk of overstrain and overuse, preventing further injuries.
Hydrate
Always stay hydrated! Drinking plenty of water around 3-4 litres a day to stay hydrated. When you're hydrated, it helps your body eliminate waste products, aids muscle function and overall
body health.
Stick to a Healthy Diet
Always eat a healthy o ensure a safe recovery. However, for rapid muscle recovery, it's more than just eating enough food; it is about eating a balanced diet of nutrients. Make sure your diet includes a mix of different types of proteins, carbohydrates and fats.
Stretching
Gentle stretching after exercising can significantly ease muscle tightness and soreness. It also improves muscle flexibility, enhancing performance and reducing the risk of injuries.
Bottom Line
Overall, your muscles are an essential component of your body you must look after throughout your life. They're something you should be training a few times a week and providing ample rest for them to grow and repair. To maintain good muscle health, always stay hydrated, follow a healthy diet full of nutrients, stretch, and rest properly when needed.
