Fueling For Long Course Triathlons

At Saturday, our fundamental goal is to fortify athletic performance through the adept use of sports nutrition. This article delves into intra-workout fueling, expressly fashioned for athletes engaging in long course triathlons. We’ll tackle the cardinal roles of carbohydrates, caffeine, and protein in this stamina-driven sport.

Carbohydrates: The Keystone of Energy for Long Course Triathlon Training

External carbohydrates, predominantly sugars, are indispensable during training, primarily to preserve muscle and liver glycogen stocks. This action permits sustained high power outputs over extended durations, generating a potent training stimulus and thus spurring significant training progressions.

The efficacy of carbohydrates can be quite varied, depending on their form and the volume consumed. Employing a combination of glucose and fructose is widely advocated as they are metabolized through separate pathways – glucose via the SGLT-1 transporter and fructose through the GLUT-5 transporter. Aiming for a glucose to fructose ratio in the vicinity of 2:1 to 1:1 promotes simultaneous absorption, hence quickening the rate of carbohydrate assimilation per hour and mitigating potential gastrointestinal (GI) distress.

In endurance-heavy sports like long course triathlons, an intake ranging from 30g to 150g of carbohydrates per hour is recommended. The specific quantity depends on several factors such as the event’s intensity, duration, and individual digestive tolerance. For events of a shorter nature, a lesser hourly intake may be adequate, especially if succeeded by a carbohydrate-enriched meal.

For those who are inclined to engage in training first thing, it’s prudent to consume extra carbohydrates approximately 20 minutes before starting. This strategy helps maintain even blood glucose levels, enabling more productive training without a sudden drop in blood sugar levels. Practical options include isotonic drinks, but even plain table sugar is a viable choice.

Caffeine

Integrating caffeine can substantially enhance the quality of training sessions lasting between 30 to 120 minutes. A recommended dosage lies between 3-9mg per kg of body weight. To uphold optimal caffeine levels in the blood, it is recommended to consume smaller, steady doses of around 0.5-1mg/kg per hour during the event or training.

Dietary Restrictions and Gastric Emptying

Keeping a vigilant eye on dietary fat and fiber intake is essential during training as these can slow digestion and possibly provoke GI issues. In addition, the carbohydrate concentration has a considerable effect on gastric emptying rates. Optimal rates are generally achieved with carbohydrate concentrations in the 10-14% range. For activities extending beyond 5 hours, solutions containing 6-10% carbohydrates are suggested. Although proteins are acceptable, it’s advisable to be cautious with whey. Opt for BCAAs or whey protein isolate or hydrolysate to minimize the risk of GI discomfort due to reduced blood flow during intense exertion.

Conclusion

In summary, devising an effectual intra-workout fueling approach is critical for achieving peak performance and fostering impressive training progressions. A pivotal element of this approach involves ensuring sufficient carbohydrate intake, ideally a blend of glucose and fructose. The incorporation of caffeine can further enhance performance. Considering individual physiological variances, it is imperative to customize nutritional strategies to align with one’s unique needs for peak performance and recovery.
