💪Unhealthy skeletal muscle is a primary defect underlying many issues like cardiovascular disease and metabolic syndrome.
🔥High-intensity interval training improves insulin sensitivity and glucose regulation.
🍽️Skeletal muscle is a key site for glucose disposal and fatty acid oxidation.
🌱Skeletal muscle releases myokines that have metabolic and immune system effects.
🕒Maintaining muscle mass is crucial for longevity and reducing the risk of chronic diseases.
Why is healthy skeletal muscle important?
—Healthy skeletal muscle is important for mobility, strength, power, and independent living. It plays a critical role in glucose disposal and fatty acid oxidation, and releases myokines with various effects.
How does high-intensity interval training improve insulin sensitivity and glucose regulation?
—High-intensity interval training has been shown to improve insulin sensitivity and glucose regulation. Over time, it can lead to instantaneous effects, making it highly valuable and time-efficient.
What is the role of skeletal muscle in glucose disposal and fatty acid oxidation?
—Skeletal muscle is the primary site for glucose disposal, accounting for 80-85% of glucose disposal in the body. It is also crucial for fatty acid oxidation and mitochondrial health.
What are myokines and what effects do they have?
—Myokines are molecules released by contracting skeletal muscle. They have various effects, including substrate metabolism, lipolysis, glucose utilization, and even dampening an overactive immune system.
Why is maintaining muscle mass important for longevity and reducing the risk of chronic diseases?
—Maintaining muscle mass is associated with better outcomes, including reduced risk of chronic diseases such as cardiovascular disease and hypertension, and overall longevity.
