According to a recent research, people having common arthritis can walk fast if they exercise regularly. The study was undertaken by researchers from the Northwestern University.

Associate Professor of Medicine at Northwestern University Feinberg School of Medicine and Lead Author of the study, Dorothy Dunlop revealed that if the people are more active physically they tend to walk faster.

She further said that a small increase in physical activity can also make a difference. She is of the view that the study would be instrumental in motivating people to walk even if they suffer from pain or stiffness in the joints.

In the study, the researchers conducted a survey on 2,500 people who suffered from osteoarthritis. The respondents were asked to fill a questionnaire which required details about their physical activity.

On the basis of their activity the respondents were categorized into four groups, from the least activity to the highest activity.

It was later analyzed that 49% people who belonged to the group which indulged in least physical activity walked at a sufficient speed to cross the lights before they changed. However, in the other groups this percentage was 63, 71 and 81 respectively.
