"LEGS GO FIRST" Sacropenia

The phrase "legs go first" in bodybuilding refers to the observation that as people age, muscle loss (sarcopenia) tends to be more pronounced in the lower body compared to the upper body. Several factors contribute to this phenomenon:

1. Muscle Fiber Composition: The muscles in the lower body, such as those in the thighs and calves, are composed of a higher proportion of Type II (fast-twitch) muscle fibers. These fibers are more susceptible to atrophy with aging because they rely on neural stimulation and are less used in daily activities unless specifically targeted through resistance training.

2. Reduced Activity Levels: With age, people often become less active, particularly in activities that involve lower body strength, like running, jumping, or heavy lifting. The decline in physical activity, especially weight-bearing exercises, accelerates the loss of muscle mass in the legs.

3. Circulatory and Neurological Decline: Aging affects circulation and neural function, which can impair the delivery of nutrients and the effectiveness of muscle activation in the lower body. This can lead to a greater decline in leg strength and muscle mass.

4. Hormonal Changes: Hormonal shifts, particularly the decline in anabolic hormones like testosterone and growth hormone, can contribute to muscle loss. Since the legs have large muscle groups, they may require more anabolic stimulus to maintain muscle mass, making them more vulnerable to age-related muscle loss when these hormone levels drop.

5. Functional Decline: The lower body is heavily involved in daily activities like walking, climbing stairs, and standing up. As muscle strength declines, the functional decline is often most noticeable in the legs, which can create a cycle of reduced activity and further muscle loss.

6. Insufficient Protein: we need twice as much protein per meal than we did in our 20's and yet most >50 year olds eat significantly less. There is a certain protein per meal minimum we need to hit to achieve MPS (muscle protein synthesis) and we have to more deliberate with our protein goals as we get older.
7. Anabolic Resistance: goes hand in hand with insulin resistance. When the muscle become "resistant" it becomes problematic to get nutrients into the muscle for storage (glucose) but it also becomes very difficult to get nutrients into the muscle to feed it! With Anabolic Resistance muscles dont get fed and this too leads to muscle loss.

Mastering Midlife is my online group coaching program that starts Sept 2 - 28

My groups are large enough to be dynamic and small enough to be personal.  I do "coach" my programs, you will have full access to me (and me to you:)) 

For more information on Mastering Midlife please go to www.midlifemonth.com on that page there is a link should you want to book a complimentary call regarding the program.

I only run this program once a year, I know I am starting it on Labor day weekend :) its no biggie if you miss the first zoom as they are all recorded.
