Athletes with diabetes



















Athletes with diabetes should consult with their physician prior to beginning any exercise and nutrition program. Blood glucose levels should documented by the physician to establish a normal range for the individual. Certain exercises of a strenuous nature may be contraindicated for athletes with diabetes. Blood glucose levels should be tracked and documented by the athlete thirty minutes before exercise, and then again one hour after exercise. This self-monitored tracking of blood glucose levels helps to assist the athlete in managing nutrition and insulin requirements. Exercise is an important component in managing diabetes. A well planned exercise program can help to maintain desired body composition levels, decrease insulin requirements, increase insulin sensitivity, lower the risk of diabetic nephropathy, and reduce the risk of hypertensive and cardiovascular diseases (Anderson & Parr, 2013). 
 
Diabetic athletes are more challenging to manage than non-athletes. The demands of sport and performance enhancement training can have more pronounced effects on blood glucose levels. Frequent monitoring of an athlete’s blood glucose levels before, during, and after exercise is recommended. Athletes should have routine medical examinations and physicians clearance to exercise. A physician should supervise the diabetic athlete’s exercise and nutrition program. Diabetic identification bracelets or necklaces should be worn by diabetic athletes during all exercise and sporting activities. Athletes with diabetes should remain hydrated during the conduct of physical events. Carbohydrate intake and insulin dosage should be managed, to allow peak performance during exercise and sporting activities. Athletes should always have readily available sources of fast acting carbohydrates during all physical events. Avoiding exercise in the evenings, and at peak insulin action times is recommended, to avoid hypoglycemia (Hornsby & Chetlin, 2005).

Athletes normally have to perform a variety of aerobic and anaerobic exercises to meet the demands of their sport. Diabetic athletes have to be aware of the threats from hyperglycemia, hypoglycemia, and ketoacidosis. Aerobic exercise is primarily recommended for those with diabetes. Walking, swimming, bicycling, and rowing are the recommended aerobic training methods. Diabetic athletes who have lost their protective neural sensation should avoid walking on a treadmill, step exercises, jogging, and walking for long period of time. Thirty minutes of aerobic exercise is recommended for adults on most days. Teens, and youth athletes with diabetes, should strive for thirty to sixty minutes of aerobic exercise on most days. Resistance based, strength training is allowed for athletes who do not show signs of retinopathy and nephropathy (Colburg, 2008).

Aerobic exercise is primarily recommended for athletes with diabetes. Aerobic exercise, done at moderate intensity, for longer duration, lowers blood glucose levels. It is easier to plan for the required insulin dosage, during and after exercise, as needed. Carbohydrate intake prior to aerobic exercise is frequently required. Anaerobic exercise is required for most athletes for performance enhancement. Explosive, short duration, high intensity, bouts of power and strength during exercises such as sprints, powerlifting, Olympic weight lifting, and related weight bearing activities, do not drop blood glucose levels in the same manner as aerobic exercise. Due to the increase in adrenaline and noradrenalin, which is more common with anaerobic exercise, hyperglycemia may occur during and immediately after the training. Hypoglycemia may follow hours after an intense exercise session. Carbohydrate intake may not be required prior to anaerobic training. Both aerobic and anaerobic training have numerous benefits for the diabetic athlete. Proper management of blood glucose and insulin levels will allow the diabetic athlete to perform both types of training (Stinogel, 2010).

Olympic and professional athletes compete at much higher intensity levels than high school and college athletes. The physical requirements of the sports and training are very demanding with professional and Olympic athletes. These professional and Olympic athletes, who have diabetes, face challenges that are similar to, but greater than the challenges faced by high school and college athletes. The advances in medical treatment options, for athletes with diabetes, have come a long way. Many professional and Olympic athletes, with diabetes, have been able to manage their condition and successfully compete at the highest levels. Proper management techniques for diabetes have been successfully implemented into these athlete’s training and nutrition programs. Diabetes is no longer a show stopper for high level athletes, as it was in the past. While the demands and challenges are greater for professional and Olympic athletes, more efficient treatment methods and management techniques have emerged. These high level athletes usually have a much more robust support network than younger athletes (Evans, 2015).

Team physicians, nutritionists, athletic trainers, coaches, and other support staff ensure that elite level athletes receive the proper care that they require. Larger team operating budgets, and high levels of individual income, help provide the funding for advanced diabetic management. Professional and Olympic athletes have also demonstrated the self-discipline and commitment, which allows them to overcome obstacles presented by diabetes. These athletes have trained for many years and are more in tune with their body’s needs. Nutrition and hydration methods, in concert with any required medications, have been honed into a coordinated program, which supports the training and competition demands. Elite level athletes, with diabetes, also usually have a very positive and strong mental outlook. This allows them to view their condition as something very manageable, as opposed to a roadblock that prevents success (Evans, 2015).

Carb Loading for Performance



Carbohydrate loading is a popular method of maximizing liver and muscle glycogen levels prior to an athletic, or endurance event. Endurance athletes such as marathon runners have made a tradition of a high carbohydrate dinner feast, prior to a big event. There are numerous methods and protocols for carbohydrate loading. Some methods are safer and more effective than others. There are ample research documents available, which support carbohydrate loading prior to endurance events. Regardless of the method or protocol used, carbohydrate loading is an effective way to maximize glycogen levels, in order to optimize performance (Benardot, 2012).

An athlete requires the proper amount of fuel to perform at peak levels. Many athletes have either won or lost races, based upon their nutrition and training plans, leading up to a major competitive event. Glycogen depletion in the middle of an athletic event can be catastrophic for the athlete. Running out of fuel during an event will not only cripple performance, but may lead to medical and health issues. The training program and nutrition plan must work together to provide maximal performance during the competitive event. It is important for an athlete to understand the proper balance between training and nutrition to optimize performance. Many athletes have mistakenly prioritized training over nutrition. These athletes paid for this mistake, during their event, with substandard performance. Training and nutrition education is very beneficial for athletes who desire winning performance. The old saying that “you cannot out train your nutrition plan” is very relevant in this situation (Wax, 2015).

Muscle and liver glycogen stores provide the main fuel source during athletic events. Ensuring that an athlete’s glycogen levels are at maximal capacity, prior to an event, is a high priority task. The amount of glycogen that can be stored by the muscles and liver is limited. For optimal performance, these fuel stores must be at maximal capacity. Arduous training quickly depletes glycogen stores. During the training program, prior to a competitive event, glycogen stores are depleted on a daily basis. The refueling process must be adequate to ensure that competitive preparations can take place. Daily nutrition must be dialed in to ensure that sufficient glycogen is available. Protein cannot be forgotten during this period as muscle must be maintained and built upon. Without adequate glycogen and protein, the body will break down lean body mass, in order to replenish glycogen stores. Muscle sparing is important to maintain performance. As the competition date moves closer, training and nutrition must be adjusted as part of the event preparation. An over trained and under fueled athlete has little chance of prevailing against an athlete who did it right (Morgan, 2015).

There are numerous ways to carb load before an endurance event. Athletes must determine which method is right for them. Carbohydrate loading is a systematic and science based process. Different methods use different timelines for optimal glycogen replacement. There is a short duration, rapid loading method which has more tradition than effectiveness. In the rapid loading method, athletes deplete their glycogen levels through training. Then, usually in a twenty four hour process, athletes consume large quantities of carbohydrates to replenish glycogen stores. This is best known from the traditional feast before an event. Many marathon participants will gather in their local eatery, the night before a big race. A popular tradition utilizes an Italian style restaurant known for great pasta dishes. Spaghetti and other pasta dishes are consumed in great quantities by athletes. While this does provide the athlete with plenty of glycogen stores, it is not the most effective method, according to research. Different tapering protocols have been developed. These tapering protocols decrease training times as carbohydrate intake is increased. Long tapering protocols can range from three weeks to one week prior to an event. Everyone responds differently to various training and nutrition plans. The athlete has to determine, many times through trial and error, which method works best for them (Brown, 2015).

One of the long tapering protocols that has been shown to work well is the seven day taper. In this method, the last intense training session is completed seven days before the competition. After that, the training intensity gradually tapers off, while carbohydrate intake is maintained. One day before the event, the athlete does a very low intensity workout, while focusing on rest and relaxation. Low fiber, high starch carbohydrates are consumed to ensure that glycogen levels are at peak capacity. On competition day, carbohydrate intake and hydration levels are maintained. It is important for the athlete to allow sufficient time for digestion before the event. The time of the event dictates when the athlete should finish with eating and drinking. By following this method, the athlete should be well rested, with glycogen stores and hydration at optimal capacity. This tapering protocol is refined by the athlete over time. With continued practice, the carb loading protocol can tailored to the individual to provide maximal benefit (McDowell, 2011).

Regardless of the method or protocol used, carbohydrate loading is an effective nutrition strategy for athletes. Carbohydrate loading maximizes glycogen stores so that the athlete will perform at optimal levels during the competitive event. Research has shown that longer tapering protocols are more effective and safer than rapid methods. The athlete determines which protocol is best suited for their needs. Constant refinement of the selected protocol will maximize the effectiveness of carbohydrate loading. Having adequate fuel stores during endurance events assists with performing at peak levels. This also prevents “hitting the wall”, where glycogen levels are depleted too early. Maintaining sufficient glycogen levels throughout the train up period also prevents depletion, and allows for maximal uptake prior to the event. Muscle sparing is important as well. Optimal performance can be achieved by correctly applying carbohydrate loading methods (Munson, 2016).

Nutrition: Grocery shopping and macronutrients



I did a quick grocery store run today.

Many people ask me frequently about meal plans, grocery lists, what foods to get and other related questions.

So I thought I would show you what I actually got today.

This is just a partial list of stuff that I got to get me through the next few days.

It is all about protein, fats and carbs.

There are many different meal combos that you can make with a variety of macronutrients.

This just gives you an idea of what I normally get and the different meals that are possible.

Hope it helps. Let me know what you think.
