As a parent of a 17 year old son (at time of diagnosis) who had AA I was concerned and worried about him indulging in active sports and games. As a result, it is often the case that parents would try to shelter their children from being involved in contact sports. In my son's case, it was a gradual and unnoticeable transition, and he was able to resume tennis and squash quite naturally as he recovered from his episode of AA.
I was not aware at that time that there was available some simple chinese "breathing exercises" or qigong that was reported to be useful in asssisting improvements in health, and especially in cancer patients ( including blood disorders ).
I feel that it is always good to have some form of exercise, and for those who are interested to find out more, here is a link I recently discovered on a research report by two researchers from the Dept. of Medicine and Dentistry of the University of New Jersey entitled
A Review of Qiqong Therapy for Cancer Treatment. Concerned parents might want to check out qigong as a form of exercise and see whether it is suitable for their children with AA.
