Lifelong training
Lifelong training has been studied in 3 papers since 2018: 1 observational study in people, 2 in animals. The newest paper, Sep 16, 2020: “Behavioural and cognitive changes in aged pet dogs: No effects of an enriched diet and lifelong training”.

“Master athletes had a lower percentage of senescent naïve, central memory and effector memory CD8+ T-cells and senescent naïve and effector memory CD4+ T-cells.”
None of its findings points the other way.

What did studies of Lifelong training find?
3Studies of Lifelong training measured 3 outcomes; the most studied are behavioural and cognitive factors (1 study), picture discrimination learning (1) and CD4+ and CD8+ T-cell populations (1).

Lifelong training was not clearly linked with CD4+ and CD8+ T-cell populations in humans (master athletes compared with controls before and after acute exercise).
“No differences were founded for CD4+ and CD8+ T-cells and their subsets between master athletes and the control group at all times of measurement.”

What is Lifelong training linked with?
1Studies link Lifelong training with 1 measure, most often senescent T-cell percentage (1 study).

Lifelong training is associated with senescent T-cell percentage in humans (master athletes compared with healthy controls).
“Master athletes had a lower percentage of senescent naïve, central memory and effector memory CD8+ T-cells and senescent naïve and effector memory CD4+ T-cells.”
