Boxing is a very controversial subject for many doctors, who object because of the potential injury that may occur. For people with diabetes, the possibilities of hypoglycaemia make the regulatory authorities even more nervous, and so boxers are banned from professional boxing. This is ironic given one of the greatest heavyweight boxers was Buster Douglas! Douglas a former undisputed world heavyweight boxing champion who scored one of the most shocking upsets in sports history when he knocked out undefeated champion Mike Tyson on February 11, 1990 in Tokyo, Japan.

This site never takes a stance on such issues, merely trying to help anyone with diabetes complete theit chosen sport sucessfully.
CM has had type 1 diabetes since 2002 and treated with a basal bolus regime. His current diabetic control uses a basal bolus regime using Glargine and Novorapid.
CM is a keen boxer but he was stopped from boxing because of an episode of hypoglycaemia, even though he has good warning of hypoglycaemia
He is training as a 64 kg weight boxer and hopes to go to welter weight as a profession. He is currently using head protection.
On Monday after work he does 10 minutes of skipping exercises followed by 3 minutes of shadow boxing. He then punches bags for 7 episodes of 3 minutes. He then punches the Cad for 3 minutes and plans to spar. The same training happens on Wednesdays and Fridays.
On Tuesday he goes to the gym and does aerobic exercise or runs 3 miles. He plans to be boxing in a bout on Thursday and on Saturday morning he runs and has a rest day on Sunday.
Management suggestions are:-
1. He needs to regularise his diabetic control. This should be done by increasing his Lantus so that his morning blood sugars are in the range of 4.5-6.5 mmols.
2. He needs to regularise his carbohydrate to insulin ratio and he should check his blood sugars an hour after a meal and when he finds that his blood sugars are more than 3 mmol excursion after a meal, then he needs to increase his insulin to carbohydrate ratio. Initially, through 2 units for 15 gm and then measure it up to 2 units for 10 gm.
3. If CM is doing any sporting activity within an 1½ hours of eating and injecting then he will need to reduced his insulin down by half.
4. CM should not use his arm as an injection site as the insulin is likely to be IM and very rapidly absorbed.
5. CM can correct glucose during training. He will need to check his blood glucose before and after each training period. If his blood sugar is less than 5.5 prior to starting then he will need to take 20 gm of glucose immediately. Otherwise, he should be taking between 30-60 gm of glucose per hour of training in the form of Dextrosol tablet, Lucozade Sport, a glucose drink of 10% or Jelly Babies.
If his blood sugars still fall with this regime during training then he needs to increase his rate of glucose.
CM would be a candidate for insulin pump therapy and this could be removed during his bouts but kept on during training.
