Diabetic patients are suitable for cycling. Cycling is a medium-intensity exercise, which is more helpful for the control of patients’ blood sugar, especially for post-meal blood sugar. Patients are generally advised to take cycling exercise two hours after meals, with each exercise lasting 30-45 minutes, and not too long. If a diabetic patient sweats a lot after cycling, he or she should be properly hydrated. In addition, diabetics need to pay attention to the fact that no matter what kind of intensity of exercise should be carried out in a fasting state, which is very likely to lead to the occurrence of hypoglycemia, but to the detriment of the health of diabetics.
