Hey everyone welcome back to the barball medicine podcast I'm Dr. Jordan

Figenbaum hope you had a great weekend and happy new year on this podcast

episode 265 we're gonna take a deep dive into what

happens with physical fitness as people age. Specifically what happens to

strength as we get older and what can we do about it. Now this is an important

consideration worldwide as the population

is definitely getting older. For example, between 2019 and 2050 the number of

persons age 65 are over globally is projected to more than, while the number of children under 5 is projected to remain

relatively unchanged. By 2050, there will be 1.5 billion people age 65 or over worldwide,

which will outnumber adolescents and young adults age 15 to 24,

and there will be twice as many older people as there are children under the age of five.

Now the aging process can lead to various changes in the body of the older individual,

which can negatively impact their health,

quality of life, and fitness due to the loss of muscle mass, muscle strength, and

cardioreptory endurance.

In this podcast, I'm going to first focus on some of the mechanisms underlying the loss of muscle size and strength and then I'll take you through some experimental data involving training and sport to see what this means in the real world.

Finally, I'll make some practical recommendations for training expectations and management for older individuals.

All right, so first let's start off with some mechanisms.

With the muscles themselves, one relatively recent finding is that older individuals

tend to be more anabolically resistant than younger individuals.

Now, anabolic resistance means that in response to a stimuli that would otherwise

cause the muscle to grow such as lifting weights or consuming dietary protein,
