Sarcopenia 

From the Greek language “sarx” meaning flesh and “penia” meaning poverty/loss.

Muscle mass and strength declines at a rate of 3% – 8% per decade after the age of 30, with these figures increasing after the age of 60. It’s arguably one of the largest changes associated with aging and is a huge contributor to risk of falls, fractures, function and mortality.

 

Am I at the mercy of my age?

Although age is a risk factor in sarcopenia, there are other factors contributing to the condition such as:

  • Insufficient nutritional/protein intake.
  • Insufficient physical activity (particularly resistance training).

 

How do these affect sarcopenia?

Protein is an essential nutrient (the body requires external sources of it to survive), it has a large influence on muscle growth and retention. There’s growing evidence that as you age, you become less sensitive to the effects of protein and as a result require more of it. (Deer et al, 2015). 

In fact, insufficient protein intake is highly prevalent in the elderly (ten Haaf et al, 2018). These can be caused by a host of factors like changes in appetite, food preference and lowered physical activity levels. 

If you’ve come across my instagram posts, you’ll notice a recurring theme on how profound the effects of resistance training are. It promotes/maintains muscle mass, reduces frailty, increases bone density (particularly important for women but also men), increases/maintains strength, reduces falls risk and is associated with a host of other favorable outcomes. It’s possibly the best return on investment as far as types of physical activity go (Law, Clark, & Clark, 2016).

 

How often do I need to lift weights?

Most recommendations point to two sessions a week for beneficial health changes to occur. Having said that, one session a week will still have a positive effect especially if you are new to training. A simple full body workout will suffice.
