Their research seems to be in relation to muscle and fat - not the immune system and cancer. I wouldn't expect zone 2 training to improve "T cell exhaustion" where mitochondria are stolen from T-cells by cancer cells. > Previous studies have shown that cancer cells can use nanotubes like “tiny tentacles” to slurp up mitochondria from immune cells.
