Muscle is the foundation of athletic performance and overall health. For Brazilian Jiu-Jitsu (BJJ) practitioners and sports enthusiasts, understanding why muscle matters and how to build it effectively is crucial. In this article, we’ll dive into the insights provided by Dr. Andy Galpin, “Why Muscle Matters & How to Build Muscle,” focusing on how muscle development can impact both athletic performance and long-term health.

The Importance of Muscle

Skeletal muscle is more than just the tissue that powers movement. It plays a critical role in various aspects of health, including metabolic regulation, glucose metabolism, and even brain health. Dr. Galpin emphasizes that muscle quality and quantity are directly linked to longevity and quality of life.

Muscle and Brain Health

One of the most fascinating links between muscle and health is its impact on brain function. Research shows that lower muscle strength, specifically grip strength, is associated with an increased risk of dementia. A recent study involving half a million participants found that nearly 30% of dementia cases could be attributed to low grip strength. This highlights the importance of maintaining strong muscles not just for physical performance but also for cognitive health.

Muscle and Longevity

Muscle mass and quality are also strong predictors of longevity. According to the National Institute of Health, sarcopenia—the loss of muscle mass due to aging—poses a significant threat to longevity. People with less muscle mass are at double the risk of all-cause mortality compared to those with more muscle mass. Therefore, maintaining or building muscle becomes essential for living longer, healthier lives.

The Functions of Skeletal Muscle

Skeletal muscle is often referred to as the “workhorse” of the body because it directly interfaces with the world. Whether you are performing high-level athletic movements or simple daily tasks, your skeletal muscles enable you to interact with your environment. Dr. Galpin argues that skeletal muscle is the most important organ in the body because it regulates everything from blood glucose levels to overall energy production.

Muscle as an Organ

Skeletal muscle is now recognized as an organ system because it secretes substances and communicates with other parts of the body. Muscle cells release signaling molecules called exokines, which target organs like the brain, liver, kidneys, and lungs. This bidirectional communication is essential for maintaining overall body function and health.

Muscle Quality vs. Muscle Quantity

Both muscle quality (functionality) and muscle quantity (size) matter when it comes to overall health and performance. Muscle quality refers to the ability of the muscle to perform its functions efficiently, while muscle quantity refers to the sheer size of the muscle. Dr. Galpin stresses that while muscle size is important, muscle quality should not be overlooked.

For example, underdeveloped muscles might struggle to perform even basic functions, leading to compromised health and increased injury risk. On the other hand, well-developed muscles not only provide strength but also contribute to metabolic health and longevity.

Building Muscle: The Science of Hypertrophy

Building muscle, or hypertrophy, is not just about lifting weights; it's about understanding the biology of muscle growth. Dr. Galpin explains that muscle growth happens when muscle fibers experience stress and damage during exercise, triggering the body to repair and grow them back stronger.

Types of Muscle Fibers

Muscle fibers are divided into slow-twitch and fast-twitch fibers:

• Slow-twitch fibers (Type I): These are endurance fibers that are highly resistant to fatigue but have a slower contraction speed. They are ideal for activities like long-distance running or cycling.
• Fast-twitch fibers (Type II): These fibers contract quickly and with great force, making them ideal for explosive movements like sprinting or lifting heavy weights. Fast-twitch fibers are further divided into Type IIa and Type IIx, with IIx being the most powerful but least fatigue-resistant.

For BJJ practitioners, both types of muscle fibers are important. Slow-twitch fibers help maintain endurance during long sparring sessions, while fast-twitch fibers provide the power needed for explosive movements like throws and submissions.

Training for Muscle Growth

To stimulate muscle growth, resistance training is essential. The key principles of building muscle include:

• Progressive overload: Continuously increasing the load (weight) you lift over time to challenge your muscles.
• Volume: Performing enough sets and reps to create sufficient stress on the muscle.
• Frequency: Training muscle groups multiple times per week to optimize growth.

Dr. Galpin suggests that a combination of different training modalities—such as heavy lifting for strength, high-repetition work for endurance, and explosive exercises for power—can lead to optimal muscle development.

Recovery and Muscle Growth

One of the most overlooked aspects of building muscle is recovery. Muscles grow not during training but during recovery. Proper sleep, nutrition, and rest between workouts are essential for maximizing muscle growth.

The Role of Sleep

Sleep is the foundation of recovery. Dr. Galpin points out that elite athletes who optimize their sleep see significant improvements in both performance and recovery. For those looking to build muscle, getting 7-9 hours of quality sleep each night is critical.

Nutrition for Muscle Growth

Nutrition plays a crucial role in muscle growth, particularly protein intake. Dr. Galpin recommends consuming about 1.6-2.2 grams of protein per kilogram of body weight per day for optimal muscle growth. He also emphasizes the importance of consuming sufficient calories to support muscle repair and growth.

Common Myths About Muscle Building

There are several myths surrounding muscle building, many of which Dr. Galpin addresses in the video:

• Myth 1: Muscle turns into fat if you stop training. This is not true; muscle and fat are two different tissues. If you stop training, you may lose muscle mass and gain fat, but one does not turn into the other.
• Myth 2: You can’t gain muscle after a certain age. While it’s true that building muscle becomes more challenging as you age, it is still possible to gain muscle at any age with proper training and nutrition.
• Myth 3: You need to train for hours to build muscle. Short, intense training sessions can be just as effective, if not more so, than long workouts.

Final Thoughts

Muscle is a vital organ system that impacts nearly every aspect of health and performance. Whether you are a BJJ practitioner looking to improve your grappling skills or a general sports enthusiast aiming to enhance your health, building and maintaining muscle should be a top priority. By focusing on both muscle quality and quantity, using a variety of training techniques, and prioritizing recovery, you can unlock your full athletic potential and improve your overall well-being.
