Creatine is a somewhat rare supplement in that there is plenty of evidence that backs its use. It improves strength, enhances recovery, and increases muscle mass. It does not however, work on every activity. The evidence on creatine use to improve aerobic activity, high intensity exercise, sprints, and decrease body fat is at best, mixed.
The research on creatine and cardio was at best, mixed. While cardio is long and low or moderate intensity, sprints are typically shorter and done at a much higher intensity. What we know about creatine means that it should be a perfect match for this short but high intensity type of exercise.
