From: Lifelong endurance training attenuates age-related genotoxic stress in human skeletal muscle
The effects of HIT exercise on total PARP-1 protein content measured pre-exercise (Pre), immediately post-exercise (Post) and three days post-exercise in young trained (YT), young untrained (YU), old trained (OT) and old untrained (OU) participants. There was a significant group by time interaction (P = 0.026) with total PARP-1 increasing following the exercise in the YU group whilst decreasing post-exercise in both OT and OU.
