Nutrient timing for athletes -

Thus, you can restore glycogen more quickly and prepare for your next workout, when you consume a combination of carbohydrate and protein and for the record, a few grams of fat does not delay absorption significantly.

A recent trend in fitness and athletics is a push for real food instead of pills, powders and bars. Supplement manufacturers lead you to believe that liquid calories are superior to solid foods because they are absorbed more rapidly.

And in a laboratory setting, this may be the case. But the only reason to use a supplement over a food is convenience. Few of us have live-in chefs and all of us have busy schedules, so quite often carrying a bar or shaker bottle are the only viable options.

When you do have the opportunity to prepare a meal, the extra digestion time compared to a shake will not hinder glycogen or protein resynthesis.

In fact lean meats, fruits, vegetables and whole grains have the benefit of more vitamins, minerals and antioxidants than the contents of your shaker bottle and may be considerably less expensive. Transportable food options such as chocolate milk, fruit, yogurt, trail mix, homemade energy bars and sandwiches may provide the best of both worlds.

As whole foods, they are nutrient dense and unprocessed, yet easy to take to the office or gym. High-water foods such as melons, apples, pears, cucumbers and bell peppers provide the benefit of assisting with re-hydration as well but you still need to drink water before, during, and after exercise.

A quick note regarding chocolate milk, which some tout as the best post-workout option. Low-fat chocolate milk has a great ratio of macronutrients, provides vitamins and minerals and is incredibly cost-effective.

However, most of the research involving chocolate milk is flawed as it has been compared to lower-calorie drinks and it is no more or less effective than a similar drink or food providing the same amount of calories, carbohydrates and protein.

Your goals are an incredibly important consideration when making pre-, during, and post-workout food choices. Two different people, for example—one with weight-loss aspirations, one with healthy weight gain ambitions—should have two different fueling plans.

For a weight-loss plan, total calories and carbohydrate should be less compared to a hypertrophy plan; protein, however, should remain relatively constant see below for more details.

No one lives in a laboratory and almost no one measures every ounce of food or calculates carbohydrates and proteins down to the tenth of a gram. For a pound individual with the goal of maintaining or gaining weight , these recommendations boil down to 90 grams of carbohydrate and 30 grams of protein a carbohydrate-to-protein ratio.

Depending on your goals, the correct timing for taking certain supplements may actually aid performance For example, performance-enhancing supplements like caffeine must be taken at the right time in order to have the proper effect This also applies to food.

A well-balanced, easily digestible meal eaten 60— minutes before a workout may improve performance, especially if you have not eaten for several hours In contrast, if your goal is fat loss, training with less food may help you burn fat, improve insulin sensitivity and provide other important long-term benefits 17 , Hydration is also closely linked to health and performance.

Many people tend to be dehydrated before working out, so it may be important to drink around 12—16 oz — ml of water and electrolytes before the workout 19 , 20 , Additionally, vitamins may affect workout performance, and may even reduce training benefits.

So although vitamins are important nutrients, it may be best not to take them close to your workout Nutrient timing may play an important role in pre-workout nutrition, especially if you want to maximize performance, improve body composition or have specific health goals.

Instead, what you eat for breakfast has become the hot topic. Many professionals now recommend a low-carb, high-fat breakfast, which is claimed to improve energy levels, mental function, fat burning and keep you full. However, while this sounds great in theory, most of these observations are anecdotal and unsupported by research Additionally, some studies show that protein-based breakfasts have health benefits.

However, this is likely due to the many benefits of protein, and timing probably does not play a role Your breakfast choice should simply reflect your daily dietary preferences and goals.

There is no evidence to support one best approach for breakfast. Your breakfast should reflect your dietary preferences and goals. This reduction of carbs simply helps you reduce total daily calorie intake, creating a calorie deficit — the key factor in weight loss.

The timing is not important. In contrast to eliminating carbs at night, some research actually shows carbs can help with sleep and relaxation, although more research is needed on this This may hold some truth, as carbs release the neurotransmitter serotonin, which helps regulate your sleep cycle.

Cutting carbs at night is not a good tip for losing weight, especially since carbs may help promote sleep. However, further research is needed on this. Instead, focus your efforts on consistency, daily calorie intake, food quality and sustainability. Whether your diet is high or low in carbs, you may wonder if timing matters to reap their benefits.

Let's look deeper:. Researchers have found that a daily multivitamin supplement was linked with slowed cognitive aging and improved memory. Additionally, stored carbohydrate energy glycogen and glucose and lost fluids may take time to replace.

By replacing fuel that was burned and providing nutrients to muscle tissue, you can ensure that your body will repair muscle fibers and restore your energy reserves. If you train hard on a daily basis or train more than once a day, good recovery nutrition is absolutely vital so that your muscles are well stocked with energy.

Most people think of recovery as the time right after exercise, which is partially correct, but how much you take in at subsequent intervals over 24 hours will ultimately determine your body's readiness to train or compete again.

Nutrient timing capitalizes on minimizing muscle tissue breakdown that occurs during and after training and maximizing the muscle repair and building process that occurs afterwards.

Carbohydrate stored in muscles fuels weight training and protects against excessive tissue breakdown and soreness. Following training, during recovery, carbohydrate helps initiate hormonal changes that assist muscle building.

Consuming protein and carbohydrate after training has been shown to help hypertrophy adding size to your muscle. Nutrient timing can have a significant impact on immunity for athletes. Strenuous bouts of prolonged exercise have been shown to decrease immune function in athletes.

Furthermore, it has been shown that exercising when muscles are depleted or low in carbohydrate stores glycogen diminishes the blood levels of many immune cells, allowing for invasion of viruses.

In addition, exercising in a carbohydrate-depleted state causes a rise in stress hormones and other inflammatory molecules. The muscles, in need of fuel, also may compete with the immune system for amino acids. When carbohydrate is taken, particularly during longer-duration endurance training two to three hours , the drop in immune cells is lessened, and the stress hormone and inflammatory markers are suppressed.

Carbohydrate intake frees amino acids, allowing their use by the immune system. Carbohydrate intake during endurance training helps preserve immune function and prevent inflammation.

Certain vitamins and minerals also play a role in immunity: iron, zinc, and vitamins A, C, E, B6, and B However, excess intake of iron, zinc, and vitamins A, C, and E can have the opposite effect and in some cases impair the body's adaptation to training.

An eating plan incorporating all of these nutrients in reasonable quantities, such as amounts found in food, can help athletes maintain immunity.

The quality of the foods selected is very important and needs to be just as much of a priority as the focus on carbohydrate or protein, for example. For instance, eating a bagel for the carbohydrate but also including an orange for the vitamin C is important; drinking a protein shake can be helpful at the right time, but including some lean steak or shellfish for the iron and zinc is also essential.

Did you know that dehydration and low blood sugar can actually increase your risk of injury? Avoiding injury due to poor nutrition is absolutely within your control. Inadequate hydration results in fatigue and lack of concentration.
