As we age, our muscles naturally begin to weaken, a process known as muscle aging, or as doctors like to call it, sarcopenia. This decline often starts in our 30s and tends to speed up once we cross the 50-year mark. Factors such as a drop in protein synthesis shifts in our hormones, and less physical activity contribute to this muscle loss.
Over time, this means our muscles might not be as strong or endure as much as they once did. This can make moving around more challenging and might make us more prone to getting hurt from falls.
To fight back against muscle aging, it's beneficial to stay active, especially by doing resistance exercises. Eating well and ensuring enough protein intake can also help keep our muscles in better shape as we grow older.

What causes muscle aging?
Reduced Protein Synthesis: As we grow older, our bodies tend to be less adept at both creating and repairing proteins. Given the importance of proteins in building and sustaining muscle, this decreased efficiency can lead to muscle loss over time.
Hormonal Changes: Hormones have a pivotal role in our muscle health. As the years roll by, we naturally experience a decline in the production of certain hormones like testosterone, growth hormone, and IGF-1, which are instrumental in muscle growth and upkeep.
Decreased Physical Activity: Over the years, many of us might find ourselves being less active. This can be due to a range of reasons, from health constraints to simply settling into a more sedentary routine. When we're less active, our muscles aren't engaged as much, leading to potential muscle weakening.
Nutritional Factors: Our diet is foundational to our muscle health. If we don't ensure a balanced intake of necessary nutrients, particularly proteins, our muscles might not receive the sustenance they need, which could speed up muscle aging.
Inflammation and Oxidative Stress: Aging can sometimes be accompanied by a higher level of inflammation and oxidative stress in the body. These can pose challenges for muscles, hindering their repair and regeneration.
How to combat muscle loss?
Resistance Training: Engaging in resistance or strength training exercises is a wise choice. Activities such as lifting weights, utilizing resistance bands, or participating in bodyweight routines like push-ups and squats all play a role in stimulating muscle growth and bolstering strength.
Progressive Overload: There's value in elevating the intensity of resistance training exercises at a steady pace. Progressive overload, as this method is known, fosters muscle adaptation and expansion.
Adequate Protein Intake: It's of significance to verify that the diet is rich in high-quality protein. This nutrient is indispensable for the repair and augmentation of muscles. Turning to lean protein sources, such as chicken, fish, or beans, can be beneficial.
Balanced Nutrition: Upholding a well-rounded diet that encompasses a spectrum of nutrients is imperative. Certain vitamins and minerals, most notably vitamin D and calcium, play a crucial role in the well-being of bones and muscles.
Stay Hydrated: Ensuring proper hydration is foundational for muscle operations. Insufficient hydration can usher in muscle cramps and impair athletic performance. It's pertinent to consume ample water daily, especially bracketing exercise sessions.
Hormone Replacement Therapy: For certain individuals, hormone replacement therapy might be a viable option, especially if hormonal imbalances are a contributory factor to muscle deterioration.
Balanced Exercise Routine: It is prudent to amalgamate resistance training with other exercise modalities, such as cardiovascular pursuits like walking or swimming. This multifaceted approach bolsters overall fitness and aids in preserving muscle efficacy and adaptability.
Adequate Rest and Recovery: Muscles benefit immensely from periods of respite after strenuous exertion. Overzealous training can be counterproductive. It's often recommended to earmark around 48 hours of rest after intensive resistance training sessions that concentrate on identical muscle groupings.
To combat muscle loss caused by muscle aging, prioritize resistance training, balanced nutrition, and overall health, thus ensuring a multifaceted approach for success.
