muscle is a critical predictor of longevity.
Your muscles are critical predictors of healthy aging.
*One of the most crucial factor in healthy ageing is muscle strength. Sarcopenia the age-related loss of muscle mass and strength, leads to reduced physical function and mobility.
*Low-grade, age-related inflammation ( “inflammaging”) accelerates muscle protein breakdown.
Muscle burns more calories than fat, so losing it often leads to weight gain and a higher risk of Type 2 diabetes.
Research consistently indicates that higher muscle mass and physical strength are directly correlated with reduced all-cause mortality, including metabolic decline, and physical frailty, these are often predicting lifespan better than body mass index (BMI).
And, muscles gets weaker as we age. Thus, maintaining a some muscle mass is crucial for the overall health, healthspan, and quality of life.
From metabolic benefits to injury prevention to support for cognitive function, muscle plays a fundamental role in all of body functions.
Sleep is a crucial factor for repairing muscles after workout. The body releases growth hormone during the first two hours of deep sleep. Studies show that just one night of no sleep can slash muscle protein synthesis rate by 18% and shift your metabolism into a catabolic, muscle-breaking state.
Other aspects affect muscle growth and recovery such as inconsistent nutrition, physical inactivity and stress.
Gradually increasing weight or repetitions over time forces aging muscles to adapt and grow stronger.
