Nutrient Timing for Track Runners

At Saturday, we're a team committed to enhancing performance through effective nutrition. Today, we're honing in on the crucial role of nutrition scheduling for track runners. Integrating a well-planned approach to nutrient timing can remarkably impact your performance and body composition, marking a vital element in any serious training program.

Frequency of Meals

Moving to the topic of meal frequency, the number of meals you have daily can be crucial in fueling your training sessions and facilitating recovery. As an active track runner, it's recommended to strive for 4-8 meals a day. Bear in mind, this involves smaller meals or snacks, not exclusively full meals.

The timing of these meals is centered around the "workout window". In this scenario, the workout window refers to the span about 4 hours before exercise, extending up to 6 hours post-exercise. Within this timeframe, your diet should be rich in carbohydrates and protein, but lower in fats to ensure rapid availability of energy for your training sessions. However, for endurance athletes, the workout window may not be as pivotal due to their typically high volume of training and calorie expenditure. Hence, carbohydrates can and should be consumed throughout the day. However, for those track runners keen on weight loss, the workout window remains a significant factor, with carbohydrate intake being primarily reduced outside this window.

Timing of Protein Intake

Protein plays a vital role in muscle recovery and growth, and its consumption should be evenly distributed across all meals during the day to counter muscle protein breakdown. Since our bodies do not store protein the same way it stores carbs and fats, it becomes crucial to continually replenish our blood amino acid pool.

Timing of Carbohydrate Intake

Carbohydrates, the main energy source during endurance activities such as track running, should predominantly be consumed within the workout window. This strategy ensures that carbs are readily available for performance, filling up liver and muscle glycogen, and boosting blood glucose in preparation for training. During the workout, sugary carbs like sports drinks and gels are the ideal choice, as they help conserve liver and muscle glycogen while minimizing the risk of gastrointestinal distress. The bulk of your carb intake should be right before, during, and after training. Furthermore, it's essential to limit fiber intake during this period as it can cause gastrointestinal issues and hinder your performance.

Timing of Fat Intake

While fats are essential for overall health, their consumption must be strategically timed. Given the slow digestion of fats, consuming them around or during workouts can potentially slow down the absorption of consumed carbohydrates. This delay could prevent these carbs from quickly reaching your blood and active tissues, which is undesirable during workouts. If you're training more than once per day, it's best to avoid fats in the post-workout window, as they can delay carb absorption and hence the replenishment of glycogen stores necessary for the next training session.

Conclusion 

To summarize, the significance of nutrient timing in enhancing performance and recovery is paramount for track runners. It's all about discerning when to eat what - a valuable insight that can dramatically impact your running performance. Aim for 4-8 meals daily, with meal sizes and compositions adjusted according to your workout routines. Distribute protein intake evenly throughout the day to avert muscle protein breakdown. Concentrate your carbohydrate intake within the workout window, limiting fiber intake during this phase to prevent gastrointestinal distress. Lastly, restrict fat intake around and during workouts to ensure prompt and efficient energy availability.
