Treadmill Running Exercise
Objective: To determine whether treadmill running exercise provides neuroprotection against brain insults of different etiology and anatomy, and whether this protection is mediated by circulating insulin-like growth factor I (IGF-I)

Protocol Steps
Treadmill running exercise protocol
Laboratory rodents were submitted to treadmill running exercise at a distance of 1 km per day
Note: Exercise was performed either before or after neurotoxin insult, or along the progression of inherited neurodegeneration

“Laboratory rodents were submitted to treadmill running (1 km/d) either before or after neurotoxin insult”
Hippocampal insult induction
Domoic acid was administered to induce hippocampal insult in some animals
Note: This was one of three different types of brain insults tested

“neurotoxin insult of the hippocampus (domoic acid)”
Brainstem insult induction
3-acetylpyridine was administered to induce brainstem insult in some animals
Note: This was one of three different types of brain insults tested

“brainstem (3-acetylpyridine)”
Cerebellar neurodegeneration observation
Animals with inherited neurodegeneration affecting the cerebellum (Purkinje cell degeneration) were observed along progression
Note: This was one of three different types of brain insults tested

Anti-IGF-I antibody administration
A blocking anti-IGF-I antibody was administered subcutaneously to exercising animals to inhibit exercise-induced brain uptake of IGF-I
Note: This was performed to determine whether neuroprotection by exercise is mediated by IGF-I

Behavioral performance assessment
Animals were assessed for recovery of behavioral performance compared with sedentary controls
Note: Assessments included spatial memory in hippocampal-injured mice and motor coordination in brainstem- and cerebellum-damaged animals
View evidence from paper
“animals show recovery of behavioral performance compared with sedentary ones, i.e., intact spatial memory in hippocampal-injured mice, and normal or near to normal motor coordination”
Neuronal assessment
Neuronal impairment or loss was assessed in all types of injuries
Note: Exercise blocked neuronal impairment or loss in all types of lesions

“exercise blocked neuronal impairment or loss in all types of injuries”
