Sports foods vs sports supplements
Do you know what is the difference between sports foods vs sports supplements? Which one will improve your performance? What are sports foods and sports supplements? Sports foods Sports foods are foods or drinks specifically formulated to meet sport-specific needs (1, 2). Despite they resembling regular foods, they are not meant to be consumed as the sole source of an athlete’s nutrition (1). Sports foods may be designed to provide one or more of the following: Despite the fact that some common foods now include some of the elements listed above (most notably, protein), they are not automatically considered sports foods. Sports foods include: These foods are designed to be…

5 ways to eat more protein
Many people struggle to eat enough protein, for example athletes and older adults. Below are 5 ways to eat more protein without necessarily adding volume or energy to your meals. 1. Choose higher protein versions of the same food These days you can find high protein yoghurt, milk, cereal, bread, wraps, pasta, etc. Hence, the easiest way of increasing your protein intake is to choose a higher protein version of the same foods you are already eating. On this topic, many people choose plant-based dairy food substitutes (e.g. milk, yoghurt) without realising that most contain less protein than the dairy-based option. 2. Increase the protein portion size This is the…

Carbohydrate for sports
The use of carbohydrate for sports has been well-known for several decades. The amount and timing of carbohydrate intake depends on many factors, including the duration, intensity and type of exercise. Roles of carbohydrate in sport As seen in the previous article, the main role of carbohydrate in the body is the production of energy. During exercise, this can translate to: In the time between training or competition bouts, carbohydrate intake is important to: The amount of carbohydrate an athlete requires during and around exercise depends on several factors: It is important to mention the fact that the individual factors listed above can change with habits. When it comes to…

Sleep and nutrition in athletes
Sleep and nutrition in athletes is an often overlooked aspect of recovery and performance. In this article, we explore the multiple factors that can affect an athlete’s sleep quality and quantity. Sleep in athletes Many athletes suffer from sleep issues, including short duration of sleep (a.k.a. sleep deprivation) and sleep disturbances (e.g. insomnia, waking up at night) (1, 2). The factors that may contribute to sleep issues in athletes include: Muscle soreness (1) and pain Intense training (1) Early or late training sessions or competition (2, 3, 4) Poor sleep hygiene, including screen use close to bedtime (2, 3) Stress, nerves and/or anxiety due to competition or other reasons (2,…

Nutrient timing
Nutrient timing guidelines are based on the observation that certain nutrients taken at particular times surrounding exercise can improve athletic performance and training adaptations. Nutrient intake is not only necessary for use as fuel during exercise but also necessary for recovery, tissue repair, muscle growth, bone remodelling, immune function, good mood, etc. Generally speaking, you can divide 3 stages: pre, during and post. However, for many athletes there is a blurring of stages as the post-exercise period from one session becomes the pre-exercise period of the next session. Nutrient intake is essential in the pre and post stages, and in some cases during sessions. But it’s not enough with eating…

How does alcohol affect exercise?
Within the realm of sports, alcohol has been viewed as a performance-enhancing drug, a rehydration beverage, a social lubricant and a post-event treat. Although it is generally understood that excess alcohol intake can be detrimental to health, the answer to “how does alcohol affect exercise?” is less clear. Alcohol consumption is a socially acceptable and expected aspect of team and other sports, and major alcoholic beverage brands often sponsor sports teams and events. Therefore, instead of pretending we can remove alcohol from athlete’s diets, it is more useful to identify which aspects of exercise can be affected by its intake. How does alcohol affect exercise? Energy balance Alcohol is a…

How to prevent and reduce DOMs
If you have ever engaged in exercise, chances are you have experienced delayed-onset muscle soreness, a.k.a. DOMs. In this article we explore how to prevent and reduce DOMs. What is DOMs Delayed-onset muscle soreness (DOMs) describes the tenderness and soreness that may be experienced after exercise. It normally peaks 24-72 hours after exercise and goes away after 5-7 days (1). DOMs typically occurs after performing exercises one is not used to (i.e. unaccustomed exercise) and/or eccentric exercise (i.e. controlled lengthening of muscles) (1, 2, 3). The most commonly cited potential causes for DOMs include lactate build-up in muscles, inflammation, muscle spasm, muscle/connective tissue damage, increased muscle temperature (1, 3). There…

Fibre in sports nutrition
In a previous post, I highlighted the relationship between fibre and health. In general, dietary fibre is good for you. However, the role of fibre in sports nutrition is a little more complex. Fibre in sports nutrition When talking about dietary fibre intake in the context of sports nutrition, we need to think beyond health. It is also important to consider weight and body composition, performance during training and competition, and recovery. As a reminder, the recommended daily intake of dietary fibre is 25 grams per day for most adult women and 30 grams per day for most adult men. Regulation of energy intake Dietary fibre intake increases satiety. Therefore,…

What is glycogen?
Glycogen is how our bodies store carbohydrate. It is predominantly stored in our muscles and liver and provides the glucose needed for exercise, particularly the high intensity type. What is glycogen? Glycogen is a branched polymer of glucose used as fuel storage. Plants store glucose in starch, we do it in glycogen (1). Most glycogen in the body is located in the muscle (~300-700g) and liver (~100-200g) (2, 3). Each gram of glycogen is stored in our muscles with 3-5g of water. Therefore, carbohydrate loading will lead to weight gain (3, 4). Roles of glycogen Some of the roles of glycogen include: Fuel source, providing carbohydrate to working muscles (2,…

Beer as a rehydration drink
Beer is a popular “post-workout” drink. It is not commonly treated as a sports supplement by athletes but as a post-competition reward and social lubricant. Is there any merit in using beer as a rehydration drink? Rehydration Rehydration is essential for recovery and performance. Athletes can lose large amounts of fluids and electrolytes through sweat during training and competition, which need to be replaced accordingly. Thus, rehydration beverages should contain water, sodium, potassium and carbohydrate (1, 2). Sodium and carbohydrate are of particular importance because they help absorb and retain water (2). The actual amounts of each component will depend on the type of event, etc. (1). Nutrients in beer…
