Muscle Tissue as a Metabolic Regulator Against Aging
Muscular Development|August 2022
Less muscle will lead to insulin resistance, since muscles are the number one metabolic regulator of the body that burns glucose. Insulin resistance will lead to type 2 diabetes and dyslipidemia, metabolic syndrome and cardiovacular disease.

Muscle Tissue as a Metabolic Regulator Against Aging

Contractile-skeletal-striated muscle tissue is not just useful for locomotory purposes. On the contrary, it is a metabolic regulator with important functions, being valuable for longevity. However, according to nutritionist powerlifter-medical doctor Mauro Dipasquale, B.Sc., MD, MRO, MFS, "We carry our own fat, while our muscles carry us."

Apart from thermogenesis and stimulation of basal metabolic rate (BMR), skeletal muscles have abilities of critical importance. Striated muscles support bones and skeleton, improve posture and contribute to proper breathing. Intercostal muscles, sternocleidomastoids, serratus anterior and levator scapulae are secondary muscles, along with the main muscle of respiration, the diaphragm. Contractile muscles affect protein metabolism, since muscles consist of protein and amino acids. The role of proteins is fundamental, considering that their building blocks participate in formation of immunoglobulins (Ig A, IgD, IgE, IgG, IgM), enzymes and peptides or hormones.

Skeletal muscles are able to store 90% of glycogen in the body, leaving a small portion to the liver. Moreover, they contain an amino acid pool, responsible for nitrogen retention. These aminos are broken down in cases of stress, such as starvation and malnutrition.

Gluconeogenesis is a complex procedure, taking part in hepatic parenchyma. From protein, glucose is produced, serving as immediate energy source for the brain and muscles. During trauma, or burns, aminos serve also as indirect energy source, through gluconeogenesis. Glucagon is another regulator of glycogenolysis, under the presence of catecholamines and epinephrine, in particular. Under a condition of muscle wasting, this supporting mechanism is compromised. This obviously equals slower recovery and recuperation. Furthermore, BMR slows down and that affects all organs' activity. Eventually, there is poor quality of living.

Best Cardio for Fat Loss - High Intensity vs. Low Intensity

Low-intensity cardiovascular exercise is the most common way to reduce body fat, despite mounting scientific evidence showing this form of cardiovascular training may not burn body fat as effectively as high-intensity cardio. In addition, low-intensity cardio has also been shown to inhibit muscle growth¹2, making the use of this approach to enhance your physique even more questionable.

BRYAN JONES: THE LORD OF CLASSIC RETURNS!

It seems like a decade has passed since the pandemic began in 2020. That was a chaotic year for all of us. MD sent me to Atlanta to cover the Chicago Pro, because restrictions in Illinois made it impossible to hold Tim Gardner's annual extravaganza there. The athletes still showed up in force to compete, and the Classic Physique division alone featured 30 men. When they came out to be adjudicated, one man stood out in a flash as the one to beat. I had never heard of Bryan Jones until that point aside from a vague recollection that he'd won the USA a couple of years before. With his braided and colored hair piled on top of his head in a gathered bun with the ends appearing to be some type of bizarre plant, I dubbed him \"The Kai Greene of Classic.\" That didn't stick, thankfully, because Bryan \"Lord\" Jones is a unique athlete in his own right. I knew I was looking at a man who was going to make waves in that division. A few months later he did just that, placing fifth in his first Olympia appearance. But we only saw him twice more after that, at the Arnold Classic and once again at the Olympia at the end of 2021. Since then, Jones has been working hard to build the additional size needed to successfully transition to the Open category. I spoke with him about his brief but notable time in Classic, and how he plans to make a big splash in Open.

HOW MUCH REST IS BEST?

Getting enough rest after weight training is essential for optimal muscle growth and performance. Unfortunately, many get insufficient rest because they simply disregard the fact that weightlifting breaks down muscle tissue, creating the requirement for adequate rest to fully recuperate.

Get Peeled With Extra Virgin Olive Oil

As you know, pathologic fat accretion results in obesity. The medical community and pharmaceutical industry have been struggling to address this burgeoning condition in the Western culture - particularly in the United States. Obviously, individuals have also been struggling in their attempts to avoid or correct unsightly or unhealthy fat gain. Imagine the shame these professionals and people must feel when they realize they may have been ignoring a risk-free, health-promoting, inexpensive dietary ingredient that can enhance fat loss. Bodybuilders seek potent drugs or supplements to force the metabolism to strip body fat to low single-digit percentages, but failing to acknowledge the foundation of diet can sabotage even their extreme measures.

CREATINE: THE BEST FORMS

New products and formulations are introduced to the supplement market every day. However, it is very rare for a product or especially an ingredient to create noteworthy evolution in supplement performance. Arguably, the greatest leap up this axiomatic evolutionary ladder occurred with the advent of creatine supplements in the 1990s. Creatine has proven over and over to be \"the real deal\" in clinical research and broscience. It's a muscle-building, performance-enhancing supplement that nearly all athletes should use.
