This email is about changes in flexibility and muscle strength as we get older.
Flexibility decreases with age. Someone in their late teens is going to be more flexible than someone int their late twenties and so on,
This was a question we had gotten. Why was it so hard to stay flexible.
So, there are two things going on.
It’s true that we become tighter and less flexible with age. But why?
I wanted to know what researchers were coming up with.
One article was interesting. They talked about muscle strength reduction as you get older, and taking in more protein did not help. The article picked up on two things that are very important.
1. Researchers did not consider increased insulin as a factor in the inability to build muscle. Researchers failed to prove that pre-diabetes caused the inability to maintain muscle strength – make new muscle.
2. Inflammation was the leading reason for not making new muscle as you get older.
Another article showed that the amino acid creatine did help build muscle.
The takeaway:
1. Stretches. From young to old, stretching is very important. The hips and legs need to be stretched daily. The stretches you remember from high school start there.
2. Inflammation is aggravated by delayed onset food reactions, mold, toxic metal, and chemical exposure.
3. Potent C, Repair Guard, and EPA/DHA. The help the cells repair and stop inflammation.
4. Creatine helps. If you try this get one that is free of colorings and additives.
