I have been an insulin-dependent diabetic athlete for many years - good club standard in a number of sports: E.g. a sub-2 hour 45 minute marathon, several years elite rowing, a lot of long distance cycling with my first '100' in 2009. During that time I have had to figure out many things for myself and have made a lot of mistakes, including ending up in hospital after training on several occasions from late onset hypoglycaemia. And yet there is no question but that exercise has been of tremendous value to me. For much of that time I had no idea of where to go for encouragement or advice.
This book is very helpful in a number of ways. It explains quite a bit about exercise physiology - what actually goes on within the body - really important stuff. It describes a number of strategies for adjusting insulin dosage, etc. It turns these into advice for many sports (ranging from active gardening and housework to doing the Race across America on a bike - I had no idea that Team Type 1 (ie people just like me - albeit fitter and more skilful!) had won this several times.
This is what is best about this book - practical advice from the horse's mouth and very inspiring case studies. Really inspiring to read, for instance, about the athlete who made the Canadian Rowing Team in Athens as a diabetic. And the author is herself a competent athlete on insulin, who has specialised in this field.
Why not 5 stars? Had I not read the superb book 'Pumping Insulin' I might have been tempted - this book is good value and a good read. But to tell the truth, Pumping Insulin gave more practical advice on the arithmetic of adjusting food and insulin to exercise in one short chapter than this book does. The case study approach does tend to lead to a 'whatever works for you' set of ideas. These are interesting, but there are sums that you can do and this book does not have them set out clearly.
I would go for both books. This one complements the other perfectly. While I'd get Pumping Insulin if I could only afford one, this would be high on my Christmas List just for sheer pleasure of reading. And there *is* some very useful material in it. The two fit together very well, so why not do yourself (or someone you love) a favour!
