Medical researcher: Scientists compared a large group of joggers who habitually stretch before jogging to an equal number of joggers who do not stretch before jogging. Both groups of joggers incurred roughly the same number of injuries. This indicates that stretching before jogging does not help to prevent injuries.

A
For both groups of joggers compared by the scientists, the rate of jogging injuries during the study was lower than the overall rate of jogging injuries.
Regardless of how the groups compared to the average joggers outside of the study, we still know that, within the study, the stretching group and non-stretching group had the same number of injuries. That still needs to be explained.
B
Among the joggers in the groups compared by the scientists, many of those previously injured while jogging experienced difficulty in their efforts to perform stretches.
We still know the stretching group and non-stretching group had the same number of injuries. Regardless of difficulty during stretching, we still know the stretching group stretched before jogging. (B) doesn’t suggest that the stretching group didn’t actually stretch.
C
Most jogging injuries result from falls, collisions, and other mishaps on which the flexibility resulting from stretching would have little if any effect.
This supports the hypothesis that stretching doesn’t help prevent jogging injuries.
D
The more prone a jogger is to jogging injuries, the more likely he or she is to develop the habit of performing stretches before jogging.
This raises the possibility that stretching might reduce jogging injuries, but the two groups had the same number of injuries because the stretching group began with a higher chance of injury than the non-stretching group.
E
Studies have found that, for certain forms of exercise, stretching beforehand can reduce the severity of injuries resulting from that exercise.
The conclusion is about stretching before jogging, and it’s based on a study about stretching before jogging. Other studies about other kinds of exercise don’t affect how we should interpret the results of the jogging study described by the stimulus.
