Muscles do a lot more than just helping us lift heavy things. There are over 650 muscles in the human body, and they are responsible for every movement we make, from sitting still to speaking and breathing. They also help protect our internal organs from physical injury. For instance, skeletal muscles protect our kidneys from damage by regulating inflammation and fibrosis. Additionally, muscles act as a cushion during falls, reducing the impact on our bones and other sensitive body parts. Building muscle through strength training and exercise can improve our body's natural defence mechanism, making it similar to having pillows strapped to our bodies.

What You'll Learn
Muscles protect your skeleton
The human body is an intricate system where every organ has a specific function that contributes to the overall well-being and health of the individual. The musculoskeletal system, comprising muscles and bones, is integral to this complex network. Muscles play a crucial role in protecting your skeleton, and this protective function is multifaceted and highly significant.
Firstly, muscles act as a protective cushion for your skeleton, especially during falls or accidents. When you have a well-developed musculature, it provides padding, akin to strapping pillows to your body. This extra girth or muscle bulk helps to absorb the impact and reduces the force transmitted to your skeleton, thereby safeguarding your bones from fractures or other injuries. This protective cushioning is particularly noticeable in areas like the buttocks, back, and shoulders, which are often the first points of contact during a fall.
Secondly, muscles are instrumental in maintaining body posture and supporting your skeleton. They work in tandem with bones, joints, and connective tissues to provide stability and balance. For example, when you stand or sit, muscles are actively engaged to keep you upright and prevent your skeleton from collapsing under the weight of your body. They also assist in maintaining correct body alignment, ensuring that the skeletal structure is not compromised by improper posture.
Additionally, muscles are involved in protecting your joints, which are integral parts of your skeleton. By holding the joints in place and facilitating their movement, muscles help prevent dislocations and other joint injuries. The skeletal muscles, which make up about 30-40% of your body weight, are under voluntary control and enable a wide range of movements. They contract and relax to cause bone movement, demonstrating their protective role in maintaining the integrity of the skeletal system.
Lastly, muscles contribute to the overall strength and resilience of your skeleton. When you engage in strength training and muscle-building exercises, not only do your muscles become stronger, but your bones also benefit from increased strength. This is because the muscles pull harder on the bones, stimulating them to strengthen in response. Therefore, building muscle mass not only protects your skeleton during falls but also enhances the overall robustness of your bones.
In summary, muscles play a critical role in safeguarding your skeleton. They act as shock absorbers during impacts, maintain posture and stability, protect joints, and strengthen the bones themselves. The intricate relationship between muscles and the skeleton underscores the importance of maintaining muscular health through exercise, proper nutrition, and safety precautions to ensure the overall protection and functionality of the musculoskeletal system.

They also protect your internal organs
Our muscles do more than just help us lift heavy things. They help us breathe, pump blood through our heart and blood vessels, and move food through our gut. They also help us move our eyes to look around and enable us to speak.
Muscles are connected to bones by tendons, a special type of tissue. They work together with our bones to help us move. This is called the musculoskeletal system. When we exercise, our muscles get bigger and stronger, and our bones strengthen in response to the muscles pulling on them.
Our muscles also protect our internal organs from physical injury. For example, skeletal muscles protect our kidneys from damage. They regulate inflammation and fibrosis within the kidneys to protect renal function. Additionally, increasing muscle bulk through strength training provides cushioning for our bodies, protecting our skeleton during falls or other impacts.
The buttocks, back, and shoulders are particularly important for protecting the skeleton. Multi-joint upper-body exercises and compound lower-body movements are effective for building muscle as padding. This extra girth makes it harder to hit more sensitive parts of the body.

Muscles protect against kidney disease
Our muscles do more than just help us lift heavy things. They help us breathe, pump blood, and move food through our digestive system. They also protect our internal organs, such as the kidneys, from physical injury.
Hanatani and colleagues demonstrated that skeletal muscles provide renal protection through several mechanisms, including altering the secreted cytokines in serum, increasing eNOS, and inhibiting TGF-β. Their study suggests that maintaining muscle mass through exercise could slow down renal deterioration. This is because exercise increases skeletal muscle Akt1, a kinase responsible for its growth.
However, it is important to note that rhabdomyolysis, the breakdown of muscle tissue, can lead to kidney damage. When muscle is damaged, a protein called myoglobin is released into the bloodstream and is then filtered out of the body by the kidneys. Myoglobin breaks down into substances that can damage kidney cells. Therefore, it is crucial to seek treatment for rhabdomyolysis as soon as possible to reduce the risk of permanent kidney damage.
Additionally, loss of muscle mass is a frequent complication in patients with chronic kidney disease (CKD). This can be due to the disease itself, dialysis, inflammation, metabolic acidosis, insulin resistance, vitamin D deficiency, hormonal imbalances, amino acid loss during dialysis, and reduced dietary intake. Nutritional therapy, such as protein restriction, can help manage uremic toxins and slow down CKD progression.
Overall, maintaining healthy muscle mass through exercise and proper nutrition can help protect against kidney disease and slow down its progression.

They help you move and stand up straight
Muscles are essential for movement and posture. They enable us to move and maintain our balance by working in tandem with our bones. This is known as the musculoskeletal system, which involves over 650 muscles in the human body. Muscles are connected to bones by tendons, a special type of tissue. The contraction and relaxation of muscles cause movement, as they pull on the bones they are attached to.
The musculoskeletal system is a complex interplay between muscles and bones. When muscles contract, they pull on the attached bones, causing movement in the body. This movement can be as simple as lifting a finger or as complex as performing a sequence of dance steps. The system is so intricate that even when we sit perfectly still, our muscles are working to keep us upright.
The importance of muscle health cannot be overstated. Healthy muscles enable us to perform everyday tasks with ease and help us maintain good posture. Weak or tight muscles can lead to discomfort and pain, impacting our quality of life. To maintain muscle health, it is crucial to stay active and exercise regularly. This can include activities such as jogging, swimming, or even just raking leaves in the garden.
Additionally, strength training and muscle-building exercises can provide extra protection for our bodies. By increasing muscle bulk, we can improve our kinesthetic awareness and provide cushioning during falls or accidents. This extra padding acts like pillows strapped to our bodies, protecting our skeleton and internal organs from injury.
Overall, muscles play a crucial role in helping us move and stand up straight. Their interplay with our bones and tendons allows for a wide range of movements and activities, and their health directly impacts our quality of life.

Muscles can prevent injury from falls
Muscles do a lot more than just helping you lift heavy things. They help you breathe, pump blood through your heart and blood vessels, and move food through your gut. They also play a crucial role in protecting your body from injury during a fall.
When you fall, the way your body strikes the ground determines whether you sustain an injury or not. Your first line of defence is to learn to fall in a way that avoids hitting sensitive parts of your body, such as your skull and ankle. Your next line of defence is to increase your muscle bulk, which provides cushioning against any unplanned impact. This extra girth acts like pillows strapped to your body, making it harder to hit those sensitive areas.
You don't need to bulk up excessively, but focusing on a few key muscle groups can provide significant protection. For example, a muscular butt, back, and shoulders can protect your skeleton. Multi-joint upper-body exercises and compound lower-body movements are excellent ways to build this padding. Additionally, strengthening your stabilizer muscles, such as the gluteus medius and gluteus maximus, can help you maintain balance and prevent falls.
Lower limb muscle strengthening is particularly important for fall prevention. Studies have shown that exercise programs focusing on lower limb strengthening lead to lower fall rates in older adults. Simple exercises like squatting, standing up from a chair, and walking can help improve balance and build strength, reducing the risk of falling. However, it's important to consult a doctor or physical therapist before starting new exercises, especially if you have weak balance.
