Lastly, women should take care to get enough vitamin D. A study of NCAA female athletes at a single institution found Vitamin D aids in the absorption of calcium and is another important contributing factor to bone health.
Since vitamin D is not widely available in the diet, supplementation may be necessary and recommended for many female athletes. Female athletes may experience physiological changes based on the phase of the menstrual cycle. The proposed changes in physical performance through different phases are likely a result of factors like altered muscle activation, energy use, thermoregulation and body composition.
Women can make some changes to their nutrition plans during certain menstrual phases to achieve optimal performance, though there is still much research to be done. RELATED: How the Menstrual Cycle Impacts Running.
The menstrual cycle is divided into the following phases: 1. the follicular phase the first day of your menstrual period until ovulation — this phase is on average 16 days2.
the ovulatory phase when the ovary releases that mature egg — this phase lasts just 24 hoursand 3. the luteal phase ovulation until menstruation — this phase lasts 12 to 14 days.
These phases differ based on hormonal levels. As discussed in a review article, Recommendations and Nutritional Considerations for Female Athletes: Health and Performanceestrogen has anabolic effects, such as improved muscle strength and bone mineral density.
Peak estrogen levels are reached around days 12—14 of a normal menstrual cycle. In the follicular phase, when estrogen is rising, women exercising over 1.
As progesterone increases, estrogen will start to decline leading into the first half of the luteal phase, and energy levels may start to wane as well. During exercise, we know that women have higher rates of fat oxidation and lower rates of carbohydrate and protein metabolism compared to men since estrogen has a protein-sparing effect.
It is important that women eat enough to perform optimally and avoid signs and symptoms of relative energy deficiency in sport. Female athletes should aim for about 45 calories per kg of fat-free body mass that is, the body mass when fat is subtracted for optimal health and performance.
RELATED: Six Nutrients Trail Runners Should Be Paying Attention To. While it is likely that micronutrient and macronutrient requirements may be altered during various phases of the menstrual cycle as a result of hormonal fluctuations, we need more high-quality research before we can prescribe foods and dietary suggestions based on the menstrual cycle phase.
For instance, if a female athlete is feeling more fatigued than normal during different phases of the menstrual cycle, the intensity, duration of training or diet may need to be modified. Simply put, eating a diverse diet full of various colors and macro- and micronutrients will help women achieve the variety of essential nutrients needed for performance.
In some cases, supplementation may be necessary, and women should work one-on-one with a health practitioner or sports dietitian for an individualized plan. More Challenge. More Community. Welcome to a New Kind of Trail Running Relay.

My Story Courses Blog training plans Knowledge Base. As always, keep your scope of practice in mind as a personal trainer—make sure you're cleared to talk about nutrition with clients. Now, let's dig into the details of dietary needs for endurance. Macronutrients are the basic components of the food we eat. These are carbohydrates, protein, and fat. Eating macros in proper ratios fuel your endurance. Healthy adult eating includes ratios of:. Adjust these ratios based on the goal of the physical activity. For example, an endurance athlete would increase their carb percentage to improve muscle glycogen stores. A strength athlete would consume a higher protein intake. This would better support building more muscle mass. Carbs come in different forms. Two to know are simple and complex carbs. Simple carbs , also known as simple sugars, have one to two sugar molecules. These include glucose, dextrose, or fructose. Simple carbs break down quickly in the body. Foods with simple sugars include fruits, milk, vegetables, table sugar, candy, and soft drinks. They supply energy but lack fiber, vitamins, and other key nutrients. Complex carbs have three or more sugar molecules. You'll find these in foods like beans, whole grains, whole-wheat pasta, potatoes, corn, and legumes. So, which kind of carbohydrate should you consume? Most carbs should come from complex sources and naturally occurring sugars. Processed carbs and refined sugars should be limited or avoided. How many carbs should endurance athletes eat? There will be some differences based on the type and duration of training. This helps support the high volume of glucose needed for that level of physical activity. Each carb has 4 calories per gram. Endurance athletes should eat 8 to 10 grams of carbohydrate per kilogram kg of body weight per day. This will depend on the duration of their endurance event. For endurance training lasting 4 to 5 hours, endurance athletes should consume 10 grams per kilogram of body weight. For example, an endurance runner who weighs 70 kg and competes in an endurance event lasting 4 hours or more should consume a minimum of grams of carbohydrate daily. In comparison, a power athlete would consume fewer carbs around 4 to 5 grams per kilogram of body weight. A power athlete's focus would be more so to increase protein intake. Many people focus only on carbs for endurance exercise. However, protein intake for endurance athletes is equally important. The purpose of protein is to build and replenish lean muscle tissue. Protein also acts as a source of energy in times of caloric deficits. Animal-based protein, as the name implies, is protein that comes from animals. This type of protein is considered a complete protein. It is complete because it contains all nine essential amino acids. Animal-based protein sources include:. Plant-based protein is protein that comes from plants. Plant-based protein is considered an incomplete protein. This isn't to say it is bad, it just doesn't have all essential amino acids. Plant-based protein sources include:. Protein has 4 calories per gram. How much protein do you need to eat? Protein intake for a normal healthy adult is around 0. Endurance athletes should eat protein at 1. Athletes taking part in longer endurance events need more protein than those running shorter distances. For example, endurance athletes weighing 70 kg would need to consume 98 grams of protein daily to support their endurance exercise. Athletes who take part in strength or power sports will consume up to 2. Endurance athletes on a plant-based diet will have an increased protein requirement. This is due to a plant-based diet consisting of incomplete proteins. Endurance athletes need healthy fats in their diet. Supply two fatty acids the body can't manufacture linoleic acid and linolenic acid. There are many types of fat, some good and some not. The most significant types are triglycerides, fatty acids, phospholipids, and cholesterol. Of these, triglycerides are most commonly found in food. Fatty acids break down further into saturated, monounsaturated, and polyunsaturated fats. Endurance athletes need to minimize the amount of saturated fat consumed. Most fat calories should be in the form of monounsaturated fatty acids. When adding fat to your diet to keep up with the demands of endurance training, focus your fat intake on healthy fats 1. This includes:. In addition to the three macros, endurance athletes also benefit from some specific micronutrients. Two to consider are vitamins C and D. Vitamin C is perhaps best known for boosting immunity. But it also serves other important purposes. One is that it is an antioxidant, protecting the cells against free radical damage. Another is that it supports wound healing. According to a study , vitamin C also helps athletes recover during the competitive season 2. Citrus fruits and potatoes are high in vitamin C. So are peppers, broccoli, strawberries, and kiwi. Vitamin D is important for bone health. Weak bones mean more fractures and breaks. A study also ties adequate vitamin D levels with improved athletic performance 3. Taking a cod liver oil supplement is one way to get more of this nutrient. Orange juice and dairy are also high in vitamin D. We lose water throughout the day. It escapes our body through normal respiration, sweating, and urinary output. When we exercise, we lose more. Staying hydrated is more than about satisfying thirst. |
| Nutrition Challenges of the Female endurance athlete | J Sci Med Sport; ; — To date, most literature suggests that the menstrual cycle does not directly influence strength or power exercise performance. Processed carbs and refined sugars should be limited or avoided. In some cases, supplementation may be necessary, and women should work one-on-one with a health practitioner or sports dietitian for an individualized plan. As discussed in a review article, Recommendations and Nutritional Considerations for Female Athletes: Health and Performance , estrogen has anabolic effects, such as improved muscle strength and bone mineral density. |
| How Female Athletes’ Nutritional Needs Differ From Men’s | For women following vegetarian or vegan diets, however, she encourages them to stay away from soy. From a supplement standpoint, she recommends pea isolate as a better substitute because it has a good amino acid profile and also provides some fibre and other nutrients. Their threshold for that also adjusts, which means during that time, women will need to remind themselves to drink, because their thirst sensation changes. After a run or workout, Sims recommends slow rehydrating, rather than gulping a bunch of water down, especially during that high-hormone phase when dehydration is more of an issue. She also suggests rather than plain water or a traditional sports drink, women use one of the new f unctional hydration products. These are lower in carbohydrate too much will sit in your stomach and dehydrate you further and higher in electrolytes. For a lower-intensity workout, she suggests simply adding a bit of maple syrup and a dash of salt to your water. RELATED: Debunking the most common endurance sport nutrition myths.

Body-image issues are a common concern for female athletes. Issues often start in high school or college and continue into adulthood. Daily workouts, weekly races, and pressure to maintain a lean physique can be overwhelming when the stress of academics and social popularity are added to the mix. During the summer of , Canadian World Championship silver medalist Sara Renner graciously shared with XC Ski World www. Renner offers advice drawn from her own struggles with nutrition and performance as a world-class cross country ski racer. One of my clients is a year-old triathlete. Her work and training schedules were very tight, and it was necessary for her to eat two meals and recovery snacks away from home. Although she faithfully used sports drinks and gels to provide energy during workouts, her recovery diet was low in protein and contained little fat. Most of her calorie intake was in the evening hours, past the ideal window for recovery when muscles are primed to replace energy stores. She had deficiencies in key nutrients such as protein, fat, vitamin D, calcium, zinc, and iron despite regular consumption of fruits and vegetables. When a trained female athlete fails to recover from workouts lasting over two hours, it may be due to depleted intramuscular fat stores. Research has shown that during moderate-intensity exercise, intramuscular stores fat stored within a muscle can contribute as much as 20 to 30 percent of energy expended. In trials where female athletes performed a two-hour run at a moderately hard pace 67 percent of maximal oxygen uptake , intramuscular fat stores were not back to baseline even 70 hours later when the recovery diet was very low in fat percent energy. In comparison, consumption of a moderate fat diet 35 percent of calories restored intramuscular fat to baseline levels by 22 hours after the two-hour run. Both recovery diets in this trial were the same calorie level. Chronic deficits in calorie intake may or may not cause weight loss; however, loss of menses or irregular menses are an indication of insufficient calorie intake to support reproductive metabolism. Loss of menses, once believed to occur because of the physiologic stress of exercise, is now known to be caused primarily by an inadequate calorie intake resulting in low estrogen levels. A powerful hormone, estrogen affects many aspects of metabolism — including bone health. One study of collegiate female runners found that 28 percent were suffering from menstrual cycle disturbances. The study also showed low bone mineral densities despite regular weight-bearing activity. A diagnosis of osteopenia reduced bone mineral density or osteoporosis low bone mineral density increases the risk of fractures by two to three times. Dietary recommendations to consume adequate calcium and vitamin D will be insufficient to restore bone health unless there is sufficient calorie intake to support energy demands, and estrogen levels are normalized. A healthy diet that supports exercise training must take into account individual food preferences, genetic and medical limitations such as lactose intolerance or celiac disease, and convenience. Despite the best intentions, many women find themselves at the window of a fast food restaurant or eating what the kids want — not necessarily what they need. For example, instead of only eating a piece of fruit for a snack, include a piece of string cheese or a small Greek yogurt. Avoid foods with added sugars; use natural fruit instead. Portable, dairy-free protein sources include hard-boiled high-omega-3 eggs, seasoned tofu, soy milk, and nuts. |
