Exercise increases insulin sensitivity in T1DM and lowers insulin requirements [14]. Education on the possibility of hypoglycemia and it's symptoms should be reviewed in detail. Sports used to be a big part of Jonathan Tengi’s life. The level of muscle glycogen has been shown to correlate with the timing of exhaustion during exercise [5]. Alex encourages others with type 1 diabetes to keep fit and healthy, and to not let diabetes be a barrier. Following an episode of hypoglycaemia in the 24hrs preceding exercise the degree of counter-regulatory impairment is thought to be dose-dependent relative to the degree of antecedent hypoglycaemia and starting at a level of only 3.9mmol/l20. In new-onset diabetes, the person might be naïve to insulin; this “honeymoon period” of small need for insulin might be prolonged in athletes. An elevated HgbA1C is indicative of poor long-term glucose control, and if blood glucose is persistently high, the athlete is at risk for hyperglycemia and diabetic ketoacidosis (DKA). If the level of consciousness does not allow for protection of the airway, glucose by the oral route should be avoided. In contrast to the well-known exercise benefits for type 2 diabetes, no such obvious benefit has been found concerning prevention of T1DM and direct lowering of hemoglobin A1c (HbA1C) [11]. These initial stores can supply sufficient energy for muscles during short-term, high-intensity exercise bouts lasting from approximately 2 to 30 seconds [3]. At the moment I’m doing various types of triathlons.”. Being physically active can help keep your insulin doses under control. The physiologic hormonal and autonomic changes satisfy the glucose requirements of exercising muscle and help to avoid hypoglycemia. You should try and be doing more, because it will not only help your type 1 diabetes but it will help with everything else. The patient and physician should work together to create an individualized plan of treatment depending on the sport and extent of disease. Care should be taken in order to ensure protection of the catheter that will remain in the athlete. This use of FFAs helps lower the production of lactate [4]. Insulin is heat sensitive and overheating can occur when exercising in the heat with the pump next to the body. These processes, coupled with the increased sensitivity of muscle to insulin, lead to a rise in glucose transport into muscle (Fig. More severe hypoglycemia occurs when glucose levels drop below 40 mg/dL and the athlete may be unconscious, combative, or severely obtunded. Taking into account the peak action of each insulin, it has been advised to decrease the dose of the specific insulin that would peak during an upcoming sporting event. Glucose homeostasis requires exogenous insulin administration; due to the need of exogenous insulin, there are ongoing challenges to balancing glucose levels and insulin availability. “The JDRF One ride is one of JDRF’s big fundraising events so that was held over the weekend. A thorough review article that covers the physiology, risks, and benefits and possible complications of exercise in both type 1 and type 2 diabetics. When an athlete has an episode of hypoglycemia, that athlete is at an increased risk of further episodes of hypoglycemia due to depletion of counter regulatory hormones [8••]. Insulin pumps infuse short-acting insulin via a catheter that is replaced every 3 to 4 days. Type 1 diabetes is a chronic disease that can lead to many serious complications if not properly managed. Some error has occurred while processing your request. “On a normal weekday I would use 30 units of insulin. The athlete must be mindful of displacement of the infusion set, which can lead to a hypoinsulinemic state and DKA in a short period of time. Insulin pumps can malfunction during exercise. The activities that emphasize endurance training, aerobic conditioning, muscle tone, and that have the potential for lifelong participation have a higher likelihood of contributing to the achievement of a healthy lifestyle. During any prolonged sporting event, blood glucose should be monitored before, during, and after exercise. Now you can go online to find out about our services. Sweating can displace the pump and liquid skin preparations can be used to prevent displacement. Self-monitoring of blood glucose four times each day is advisable, as well as measuring urinary ketones prior to exercise. Insulin inhibits glucose release from the liver and FFA release from adipose tissue, and stimulates glucose uptake into muscle. Athletes with type 1 diabetes are capable of undertaking a wide array of exercise activities and there are no longer firm contraindications to certain sports for diabetic patients. Papers of particular interest, published recently, have been highlighted as: • Of importance •• Of major importance. Exercise duration of 60 to 90 minutes necessitates usage of FFAs as the main energy source. The environment can affect the overall effectiveness of an insulin pump. The athlete needs to replace fluid losses adequately. If you’re an athlete who has Type-1 diabetes, you know how important it is to keep your blood sugar under excellent control.
