According to a study published in the British Journal of Sports Medicine conducted by the researchers from Appalachian State University, Physical fitness is more effective in combating against the seasonal infections like cold and flu than normal vaccine.
The study was conducted in 2008 and 1,002 adults up to age 85 were taken. They were divided in two groups and followed for a 12-week period. Half of them were participated in the fall and the remaining people were participated in the winter.
The researchers found that after adjusting several factors such as age, sex, body mass index, fruit intake, marital status, mental stress level and education, the people who exercised for at least five days a week spent 43 percent less time with an upper respiratory tract infection than the people who exercised the least. In the same way, the highly-fit people had 46 percent less time sick than the people who had low-fitness. The severity of ill was also reduced by 41 percent in the people who had high levels of aerobic activity.
Though this study was limited by some factors such as the exposure to pathogens at home or at work, this would be absolutely great news for physically fit people and a catalyst for unfit people to start exercise.
