What is the cost of muscle flexibility?

In summary, the conversation discusses the advantages of losing muscle flexibility when certain movements are not practiced. The loss of muscle mass after stopping weight training results in a lower need for calories to maintain the remaining muscle. The concept of phenotypic plasticity, or genetic adaptations to environmental changes, is mentioned as a factor in human energy budgets and the evolution of the human genome. It is also noted that humans today have smaller brain volumes compared to our ancestors.

TL;DR Summary
How is it advantageous for muscles to lose flexibility from disuse?
Hi everyone

How is it advantageous for muscles to lose flexibility when certain movements are not practised?

For example, if you lose muscle mass after stopping weight training, you will need less calories to feed the remaining muscle. What benefit (if any) does the body get from losing flexibility?Thanks

A good start is to look up "phenotypic plasticity" - genetic mediated adaptations to environmental changes.

Bear in mind that almost all of the human genome evolved long ago :smile:
So, human energy budgets were important when the average genus Homo members were likely far more fit than a large percentage of modern Homo members.

FWIW ~40kya humans also had brain volumes larger thean us moderns. Males 17% greater, females 15% greater. Our current brain volumes are the lowest average of our species since 100000ya.

1. What is muscle flexibility?

Muscle flexibility refers to the range of motion that a muscle or group of muscles can achieve without causing pain or discomfort. It is an important aspect of physical fitness and is necessary for performing daily activities and exercise with ease.

2. What factors affect muscle flexibility?

There are several factors that can affect muscle flexibility, including age, genetics, physical activity level, and previous injuries. As we age, our muscles naturally become less flexible, and genetics can play a role in how flexible our muscles are. Regular physical activity can help improve muscle flexibility, while previous injuries can decrease it.

3. Why is muscle flexibility important?

Muscle flexibility is important for maintaining good posture, preventing injuries, and improving athletic performance. It allows our muscles to move freely and efficiently, reducing the risk of strains and sprains. It also helps to maintain a full range of motion in our joints, which is essential for daily activities and exercise.

4. How is muscle flexibility measured?

Muscle flexibility is typically measured using a goniometer, which is a tool that measures the range of motion of a joint. Another common method is the sit-and-reach test, which measures the flexibility of the hamstrings and lower back. Additionally, there are various flexibility tests specific to different muscle groups.

5. Can muscle flexibility be improved?

Yes, muscle flexibility can be improved through regular stretching and exercise. Stretching helps to increase the elasticity of muscles and tendons, allowing them to move more freely. It is important to stretch properly and avoid overstretching, which can lead to injury. Consistency is key when it comes to improving muscle flexibility, and it may take several weeks or months to see significant improvements.
