Subgroups have varied and widespread actions, diminishing the sensation of pain, inducing euphoria (e.g. 'runner's high') and interacting with the immune system.

Blood and muscle samples obtained from hunted deer after death were compared with samples from 50 non-hunted red deer that had been cleanly shot with rifles. The effects on deer of long hunts were (i) depletion of carbohydrate resources for powering muscles, (ii) disruption of muscle tissue, and (iii)
