Daily exercise until symptoms are present

Male mice 11-20 weeks old were infected with influenza virus and then randomly assigned to exercise (EX) or home cage control (HCC). The EX mice were exercised for 20 to 30 minutes for four days and multiple subjective and standard measurements were recorded.

"The animals did very moderate exercise while they were mounting an immune response," Woods noted. As soon as symptoms appeared, exercise was stopped, to mirror how most people react once they come down with flu-like symptoms. The mice were nave, that is, they previously hadn't been exercising on a regular basis.

Results both striking and surprising; human flu vaccine reaction study underway

20-week-old mice that had exercised had significantly (p=0.008) higher survival rates (18 of 22) versus HCC of the same age (10 of 22). However, 11- to 16-week-old mice didn't show a significantly higher survival rate. When all EX mice (47) were compared with all HCC mice (48), EX had twice the survival rate, 59% vs. 29.4% (p=0.003). None of the variables (food/water intake, random activity or symptom severity) proved to be reliable at predicting mortality. However, severe lethargy was apparent one to two days prior to death. And while there was a "marked, age-dependent effect on mortality, there was no effect at all on morbidity, which was somewhat surprising," Woods said.

The Illinois researchers plan on doing followup studies with animals that had been exercising regularly, as well as studies that to try and uncover the overall protective effect and its mechanisms. Areas that they'll be studying include:
