However, timing may only be relevant if you are training several times a day, or have multiple athletic events within a day. For the average person who works out once a day, there is plenty of time to replenish glycogen at each meal (10).
Eating regularly (5-7 times) throughout the day maintains proper blood sugar and energy levels, while regular exercise consistently burns consumed calories (Alencar et al. 2015). Indeed, proper timing of nutrition and activity helps lay the foundation for optimizing physical results.

Choosing the wrong foods-eating or drinking too much, consuming too little or not timing a meal efficiently-can dramatically affect outcomes. Eating the ideal pre-race/event meal can help ensure that all of the hard training and dedication pay off. Similarly, maintaining an appropriate daily sports-nutrition plan creates the perfect opportunity for better results.
The majority of nutrients in a pre workout meal should come from carbohydrates, as these macronutrients immediately fuel the body. Some protein should be consumed as well, but not a significant amount, as protein takes longer to digest and does not serve an immediate need for the beginning of an activity. Fat and dietary fiber also should be marginal to minimize the potential for gastrointestinal upset during the activity (Smith & Collene 2015).
Timing is a huge consideration for preworkout nutrition. Too early and the meal is gone by the time the exercise begins; too late and the stomach is uncomfortably sloshing food around during the activity. Although body size, age, gender, metabolic rate, gastric motility and type of training are all meal-timing factors to consider, the ideal time for most people to eat is about 2-4 hours before activity.
It is generally best that anything consumed less than 1 hour before an event or workout be blended or liquid-such as a sports drink or smoothie-to promote rapid stomach emptying. Bear in mind that we are all individuals and our bodies will perform differently. It may take some study to understand what works best for you. Athletes should experiment with the size, timing and composition of pre-event/activity meals to determine what will be best tolerated.
Some athletes prefer gels or chews to replace carbohydrates during extended activities. These sports supplements are formulated with a specific composition of nutrients to rapidly supply carbohydrates and electrolytes. Most provide about 25 g of carbohydrate per serving and should be consumed with water to speed digestion and prevent cramping.
An effective nutrition recovery plan supplies the right nutrients at the right time. Recovery is the body's process of adapting to the previous workload and strengthening itself for the next physical challenge. Nutritional components of recovery include carbohydrates to replenish depleted fuel stores, protein to help repair damaged muscle and develop new muscle tissue, and fluids and electrolytes to rehydrate.
You may have to use different timing and alternate routines to create a nutrition and exercise combo that works best. Timing certainly is critical in sports nutrition, and optimizing that can make all the difference!
Position Statement: The position of the Society regarding nutrient timing and the intake of carbohydrates, proteins, and fats in reference to healthy, exercising individuals is summarized by the following eight points: 1.) Maximal endogenous glycogen stores are best promoted by following a high-glycemic, high-carbohydrate (CHO) diet (600 - 1000 grams CHO or 8 - 10 g CHO/kg/d), and ingestion of free amino acids and protein (PRO) alone or in combination with CHO before resistance exercise can maximally stimulate protein synthesis. 2.) During exercise, CHO should be consumed at a rate of 30 - 60 grams of CHO/hour in a 6 - 8% CHO solution (8 - 16 fluid ounces) every 10 - 15 minutes. Adding PRO to create a CHO:PRO ratio of 3 - 4:1 may increase endurance performance and maximally promotes glycogen re-synthesis during acute and subsequent bouts of endurance exercise. 3.) Ingesting CHO alone or in combination with PRO during resistance exercise increases muscle glycogen, offsets muscle damage, and facilitates greater training adaptations after either acute or prolonged periods of supplementation with resistance training. 4.) Post-exercise (within 30 minutes) consumption of CHO at high dosages (8 - 10 g CHO/kg/day) have been shown to stimulate muscle glycogen re-synthesis, while adding PRO (0.2 g - 0.5 g PRO/kg/day) to CHO at a ratio of 3 - 4:1 (CHO: PRO) may further enhance glycogen re-synthesis. 5.) Post-exercise ingestion (immediately to 3 h post) of amino acids, primarily essential amino acids, has been shown to stimulate robust increases in muscle protein synthesis, while the addition of CHO may stimulate even greater levels of protein synthesis. Additionally, pre-exercise consumption of a CHO + PRO supplement may result in peak levels of protein synthesis. 6.) During consistent, prolonged resistance training, post-exercise consumption of varying doses of CHO + PRO supplements in varying dosages have been shown to stimulate improvements in strength and body composition when compared to control or placebo conditions. 7.) The addition of creatine (Cr) (0.1 g Cr/kg/day) to a CHO + PRO supplement may facilitate even greater adaptations to resistance training. 8.) Nutrient timing incorporates the use of methodical planning and eating of whole foods, nutrients extracted from food, and other sources. The timing of the energy intake and the ratio of certain ingested macronutrients are likely the attributes which allow for enhanced recovery and tissue repair following high-volume exercise, augmented muscle protein synthesis, and improved mood states when compared with unplanned or traditional strategies of nutrient intake.
Daily (circadian) rhythms coordinate our physiology and behaviour with regular environmental changes. Molecular clocks in peripheral tissues (e.g. liver, skeletal muscle and adipose) give rise to rhythms in macronutrient metabolism, appetite regulation and the components of energy balance such that our bodies can align the periodic delivery of nutrients with ongoing metabolic requirements. The timing of meals both in absolute terms (i.e. relative to clock time) and in relative terms (i.e. relative to other daily events) is therefore relevant to metabolism and health. Experimental manipulation of feeding-fasting cycles can advance understanding of the effect of absolute and relative timing of meals on metabolism and health. Such studies have extended the overnight fast by regular breakfast omission and revealed that morning fasting can alter the metabolic response to subsequent meals later in the day, whilst also eliciting compensatory behavioural responses (i.e. reduced physical activity). Similarly, restricting energy intake via alternate-day fasting also has the potential to elicit a compensatory reduction in physical activity, and so can undermine weight-loss efforts (i.e. to preserve body fat stores). Interrupting the usual overnight fast (and therefore also the usual sleep cycle) by nocturnal feeding has also been examined and further research is needed to understand the importance of this period for either nutritional intervention or nutritional withdrawal. In summary, it is important for dietary guidelines for human health to consider nutrient timing (i.e. when we eat) alongside the conventional focus on nutrient quantity and nutrient quality (i.e. how much we eat and what we eat).
Nutrient timing involves manipulation of nutrient consumption at specific times in and around exercise bouts in an effort to improve performance, recovery, and adaptation. Its historical perspective centered on ingestion during exercise and grew to include pre- and post-training periods. As research continued, translational focus remained primarily on the impact and outcomes related to nutrient consumption during one specific time period to the exclusion of all others. Additionally, there seemed to be increasing emphasis on outcomes related to hypertrophy and strength at the expense of other potentially more impactful performance measures. As consumption of nutrients does not occur at only one time point in the day, the effect and impact of energy and macronutrient availability becomes an important consideration in determining timing of additional nutrients in and around training and competition. This further complicates the confining of the definition of "nutrient timing" to one very specific moment in time at the exclusion of all other time points. As such, this review suggests a new perspective built on evidence of the interconnectedness of nutrient impact and provides a pragmatic approach to help frame nutrient timing more inclusively. Using this approach, it is argued that the concept of nutrient timing is constrained by reliance on interpretation of an "anabolic window" and may be better viewed as a "garage door of opportunity" to positively impact performance, recovery, and athlete availability.
In that study, the researchers showed that protein, carbohydrates, and creatine taken around a training session could lead to more muscle mass and strength gain than those same nutrients eaten further from the session.
To back up this idea, recent data suggests that the total amount of protein and carbohydrate you eat, over the course of the day, is more important for body composition and performance than nutrient timing strategies.
Nutrient timing is exactly what it sounds like. You eat certain foods at particular times to reach your performance goals. Drinking a protein shake after sweating in a gym, for example, is a part of nutrient timing.
Short-term markers. Blood markers are certain compounds that are released in the body as a response to something. They can be used to determine if something is effective or not. Studies around nutrient timing only focus on short-term markers rather than long-term benefits of nutrient timing. 2ff7e9595c
