Why does exercise decrease aging rate?
00:13
Oxidative stress
00:18
Oxidative stress
00:47
increased by low antioxidant levels (antioxidants can protect against ROS)
01:09
compromises the repair mechanism of DNA (carried out by telomerase)
01:15
Telomerase
01:17
builds telomeres
01:19
sparsely distributed oxidative stress hinders production even more!
01:30
= telomere attrition
01:37
= increased ageing
