Sports nutrition for swimmers -
It was hypothesized that the HCLF diet would increase carbohydrate utilization relative to a LCHF diet, resulting in an increase energy conversion per volume of O 2 consumed.
Although RER was greater during exercise following 3 days of a HCLF diet, no differences in VO 2 or C s were detected between diets. Therefore, these data do not support our original hypothesis because there was no improvement in swimming economy i.
To our knowledge, this is the first study investigating the effects of diet on swimming economy. Results from the present study are in contrast with previous research reporting an effect of diet on movement economy in cyclists, runners, and race walkers [ 7 , 8 , 12 , 13 , 14 , 15 , 24 ], though comparisons across studies are challenged by differences in study design.
Using a dietary protocol similar to our study, Cole et al. Additionally, a 5-day ketogenic LCHF diet decreased economy in race walkers [ 7 , 8 ].
Studies using longer dietary interventions e. Due to the confounding effects of ketone oxidation on RER [ 19 ], it is unclear how ketogenic vs. non-ketogenic LCHF diets influence fat oxidation and exercise economy. However, the contribution of ketone oxidation to energy production in skeletal muscle appears small when other substrates are available [ 25 ].
Taken together, the duration and type of LCHF diet used in our study are unlikely to be the reason for the lack of detectable changes in swimming economy. Differences in mode of exercise may explain the lack of effect of diet in the present study.
In comparison, the energetic cost of running and race walking are approximately half of C S values reported in the present study [ 13 , 14 ]. For swimming, minimizing drag force and maximizing propelling efficiency i.
In addition, swimming technique likely plays a greater role in swimming economy than cycling or running technique do for economy in those sports because the swimmer moves through water. Therefore, any diet effects on swimming economy may have been masked by slight changes in stroke mechanics between trials, though mechanics were neither measured nor controlled.
Our contrasting findings could also be related to the exercise intensities used in our study, which were lower than what has been used in previous studies [ 7 , 8 , 14 , 15 ]. Therefore, subjects in the present study were more reliant on fat oxidation.
In support of this hypothesis, Shaw et al. Oxygen pulse was higher following the HCLF diet. Although body weight and hydration status were not measured in this study, it is likely that the HCLF diet caused an increase in total body water due to increases in muscle glycogen [ 31 ]. Water stored with muscle glycogen would increase intracellular but not extracellular water content [ 32 ], though it is possible that this extra water may have played a role in the increased oxygen pulse observed during submaximal exercise in following the HCLF diet.
This indicates subjects were below their critical swimming velocity, above which VO 2 and lactate will not stabilize [ 34 ]. For many of the participants, this study was their first experience swimming in a flume.
Subjects received a familiarization swim prior to each trial, gained experience in the flume from their initial VO 2max test, and the order of the diets was randomized so any learning effects of swimming in the flume should not affect conclusions from this study.
A strength of this study is that the diets were individually tailored for each participant, based on their habitual food choices.
Participants were required to shop for and prepare all of their own food in the quantities specified, and could communicate with the researchers about food choices and potential substitutions if needed.
This design increases the ecological validity of this study as most recreational swimmers do not have access to the same resources as collegiate and professional swimmers whose diet and exercise volume can be more closely monitored. It is possible that participants could have been untruthful in recording their diets, although the difference in RER between diets suggests acceptable adherence.
Protein intake was significantly different between groups To our knowledge, this study was the first to examine the effects of macronutrient intake on swimming economy.
The HCLF diet increased carbohydrate utilization but did not improve swimming economy compared to the LCHF diet. Therefore, a LCHF diet may offer potential benefit for ultra-distance swimmers, who compete in long-duration, low-intensity events during which consuming large quantities of carbohydrate is challenging.
Future research should focus on how diet affects swimming economy during long-duration swims where combating fatigue and maintaining swimming economy are important for success in marathon and ultramarathon swimming events.

Carbohydrates are the essential fuel for high performance athletes. Eating carbohydrate foods at regular intervals throughout the day will top up your muscle fuel and allow you to push yourself harder in training.
All of your meals and snacks should be based on carbohydrate foods. However, not all carbohydrate foods are created equal. The quality of your carbs counts! Good quality carbohydrates will energize you, promote good health and help you perform at your best.
Good carbohydrate choices are whole grain breads, whole grain breakfast cereals, oats, pasta, brown rice, quinoa, baked potatoes, sweet potatoes, sweetcorn, chick peas, beans, lentils and fresh fruits.
Protein is essential for muscle repair and growth. Your body also needs a regular intake of protein for ongoing muscle repair and growth. It is not necessary to consume high amounts of protein as any excess protein will not turn into more muscle, but will be burned as fuel or stored as fat.
Each of your meals should include a moderate serving of lean protein, the size and thickness of the palm of your hand or one-quarter of your plate. For snacks, include some protein with your carbohydrate food.
Convenient, easy protein sources for snacks are milk, cheese, yogurt, boiled eggs and nuts. Pre-Training Nutrition. Your pre-training meal or snack depends on how much time you have before your training begins, what foods you tolerate and your personal preference.
Your meal or snack should always contain mainly carbohydrate to top up your muscle fuel which will allow you to push yourself harder and get the most out of your training session. The more time you have before training, the more protein you can include in your snack.
Some good pre-training meals and snacks include:. Always include a drink with your pre-training snack so that you start practice hydrated. A good pre-training snack will not only increase your energy levels but will increase your concentration and desire to work hard, which will make your coach very happy!
Post Training Nutrition. Missing this prime recovery window will reduce your ability to optimally refuel and repair your muscles. This is especially important if you have two training sessions in one day. Aim to eat a quick snack within minutes of finishing training. The snack should contain mostly carbohydrate g with some protein g.
Starchy foods such as rice, pasta, bread, potatoes, and cereals are great sources of this critical nutrient. The pre-practice meal is different depending on when you are consuming it. There are many examples of pre-practice meals that can be consumed at different times before your training session.
This meal should consist of mostly carbs, but also a portion of protein to keep you full throughout your practice. A turkey sandwich on whole wheat bread, pasta with meatballs aim for lean meat such as venison or pork, as fattier meats will take longer to digest , grilled chicken and rice, or pancakes with natural maple syrup are all great options.
These meals will give you the energy you need to perform your best, while also keeping you full for a significant amount of time. If you have between hours before your practice, a smaller meal will do for proper fueling. Some options include: a fruit smoothie, pretzels with hummus, and toast or a bagel with peanut butter.
These items are lighter on the stomach than the previous meals mentioned, but will provide the body with the necessary nutrients for success in the pool.
If you only have less than an hour before your training session, have no fear! There are many options to choose from that can provide the body with quick carbohydrates. Granola bars avoid ones that have a notable amount of nuts, as these take very long to digest and can lead to stomach discomfort while training , graham crackers, dry cereals, and rice cakes are all fantastic choices.
These foods are nearly all carbohydrates with a very minimal amount of protein and fat. They will digest quickly, so the muscles will be able to access them quicker and use them for energy.
It is also critical to fuel during practices, including staying hydrated. We rarely feel ourselves sweat during practice because we are in the water. However, as we expend ourselves in order to swim, we are losing water.
It is especially important to stay hydrated, making sports drinks a great option for in-practice fuel.

Choosing the Right Energy Training and competition require large amounts of energy, which comes from carbohydrates, fats and protein in your body. During workout Recovery begins the minute you start working out. Some people get an upset stomach when trying this, the challenge is to find the right carb source for you and stick with it to give your body a chance to see how much better it will feel with fuel available! During Workouts or Meets. Recovery tips to take with you Plan ahead. Begin recovery within minutes after practice or competition followed by a meal within 2 hours. Liquid carbohydrate or simple carbs can be utilized during workout or right after to speed up absorption and recovery. Your post workout snack should include carbohydrate and protein in a carb to protein ratio 3 grams of carbohydrate for every 1 gram of protein. Keep portion control in mind. The higher the volume and intensity of a workout the more fuel you need to recover with. Provide protein to aid in repair of damaged muscle tissue and to stimulate development of new tissue. More is not better, so shoot for grams of protein in your recovery snacks and meals. Drink 16 oz about 2 hours before practice and another oz about minutes before practice. Weigh yourself before you get in the pool. For every pound you lose, drink oz of fluid. Drink water with every meal to ensure pale yellow colored urine to indicate you are hydrated check out the hydration chart. After exercise, drink water with carbohydrates to speed up the recovery process. Constant intake of energy. Make sure snacks are available in their bags, lockers, cars, etc. Carbohydrates are key. It is fast, available energy. Athletes need carbs, so do not let the latest diet craze influence the way your athlete is fueled. A meet is not the time to try something new. Choose foods that do not cause GI distress. High fat, high protein foods cause GI distress. Research the area you will travel to ahead of time and determine food availability. Identify restaurants you know who offer good options, grocery stores close to the hotel, and if it is possible to prepare food in your hotel. Create a timeline with your swimmer for consuming food and fluids throughout the day. The timeline should be based on their race schedule and should be practiced prior to race day. When competing in multiple sessions, it is important that an athlete consume a post-race snack immediately to recover and prepare for their next race.. Does this product even do what it claims to do? Is there research that proves it? Is research based on the type of athlete I am age, sport, gender, etc? Has it been tested for safety by a third party? com Talk to a doctor or sports RD before you take anything. Can you get the ingredients you need from food first? Coaches Corner You are on the front lines with your athletes. Require your swimmers eat before a workout. Think about having a fundraiser to raise money to purchase non-perishable foods you can store at your facility for swimmers. Build fueling breaks into your workouts. This will show how important it is and ensures they have time to follow through. This does not have to be a stop in the middle of your practice. It can be between sets, just write it into the workout so the athletes and other coaches remember. Build hydration breaks in to your workouts. This is just as important as fueling with food. Practice what you preach. Taking care of your own body and fueling for your own health. When an athlete sees you doing what you have asked of them, they are more likely to take action! Avoid weigh-ins and group conversations about weight and body composition. If it is necessary to talk to an athlete about these things do it on a case-by-case basis and consider including a professional, such as a sports RD, to support change. Instead, as a coach you should be emphasizing healthy eating, skill development, energy availability, effort, and attitude. Supplements are not typically suggested for age group athletes. If a company, representative, athlete, or parent asks you about supplements- have a resource such as a sports RD available that can address this with them and get them reliable and safe information.
