The Effects of Physical Exercise and Cognitive Training on Memory and Neurotrophic Factors
04/02/1918:48
The next lecture I will be giving will probably be in September of 2020. I know that seems a bit far away. The lecture will be titled, “Exercise, Diet, and Cognitive Function Over the Life Span.” There is an enormous about of data that has been published on these topics, including older and newer research. I will be trickling out a few of the more relevant studies over the next several months. So, watch this space.

Resistance Exercise Reverses Aging in Human Skeletal Muscle

The following study is one of my favorites to discuss. The name says it all and is extremely powerful. Usually, scientists are very measured in their wording. You may see a study with a name such as this:
Eur J Sport Sci. 2016 Nov;16(8):1055-63. doi: 10.1080/17461391.2016.1185164. Epub 2016 May 27.
Effects of resistance training on expression of IGF-I splice variants in younger and older men.

Strength training stops the aging process in human skeletal muscle.

I was answering some questions for one our clients the other day concerning various forms of exercise / activity. I recalled this study, opened my laptop and started to discuss the relevant research with the her. This study, in particular, serves to illustrate the priority of resistance training. Read More...
Age as a Factor in Recovery from Exercise
07/18/1422:17
Joe,
“How age-dependent is this? Given the huge difference in other areas of healing depending on how old you are, it seems that muscle healing would vary similarly. I could imagine that a healthy 18 year old would be able to repair much more muscle in far less time than a healthy 50 year old. This might lead to the discrepancies in different studies on recovery time (between 2 days and more than 14 days).”
Yes, age does make difference in the requisite time to recover from exercise induced microtrauma (although, I think most of the variability is more related to genotype). In animal models, older rats showed a reduced up-regulated expression of IGF-1 splice variants when compared to younger animals. However, expression was still increased almost 3-fold over untrained conditions.
