Fueling For Krusnoman Long Distance Duathlon Competitors

At Saturday, our primary objective is to augment athletic performance by employing sports nutrition in an informed manner. This article sheds light on intra-workout fueling that’s specifically designed for the athletes participating in the Krusnoman Long Distance Duathlon, encompassing the significance of carbohydrates, caffeine, and proteins.

Carbohydrates: The Engine of Duathlon Training

During training, exogenous carbohydrates, particularly sugars, are indispensable. Their primary role is to maintain muscle and liver glycogen stores, enabling athletes to sustain high power outputs. This results in a potent training stimulus, which in turn leads to significant training improvements.

The potency of carbohydrates is highly dependent on both the type and quantity ingested. A combination of glucose and fructose is optimal as they are absorbed through different pathways. Glucose relies on the SGLT-1 transporter, whereas fructose utilizes the GLUT-5 transporter. Maintaining a glucose to fructose ratio between 2:1 and 1:1 promotes concurrent absorption, enhancing carbohydrate digestion rates per hour and reducing gastrointestinal (GI) issues.

In endurance-centric sports like the Krusnoman Long Distance Duathlon, consuming 30g to 150g of carbohydrates per hour is suggested. The precise amount hinges on the duration and intensity of the event, as well as individual digestive tolerance. For shorter events, lower hourly intake may be sufficient, especially if followed by a meal rich in carbohydrates.

For athletes who prefer to train first thing, it is advisable to consume extra carbohydrates about 20 minutes before starting. This practice aids in maintaining stable blood glucose levels, contributing to a more effective training session without the risk of blood sugar levels plummeting. Isotonic drinks are a convenient option, though common table sugar is also effective.

Caffeine’s Role

Integrating caffeine into your regimen can markedly enhance training sessions that last between 30 to 120 minutes. An appropriate dosage ranges from 3-9mg per kg of body weight. In order to keep caffeine levels in the bloodstream optimal, it is advised to consume smaller, frequent doses of about 0.5-1mg/kg each hour during training or competition.

Digestive Concerns: Dietary Limitations and Gastric Emptying

It’s vital to keep an eye on the intake of dietary fat and fiber during training as they can slow down digestion and may lead to GI issues. Additionally, the concentration of carbohydrates has a significant impact on gastric emptying rates. Ideal rates are usually associated with carbohydrate concentrations of 10-14%. For events lasting over 5 hours, 6-10% carbohydrate solutions are advisable. Although protein is allowed, it’s wise to exercise caution with whey. Opt for BCAAs or whey protein isolate or hydrolysate as alternatives to mitigate GI discomfort due to reduced blood flow during strenuous activity.

Conclusion

In summary, devising a shrewd intra-workout fueling strategy is imperative for realizing peak performance and fostering noteworthy training progress. Ensuring sufficient intake of carbohydrates, with a focus on blending glucose and fructose, is central to this strategy. The inclusion of caffeine can offer additional performance gains. It’s also important to recognize that individual physiological variances necessitate customized adjustments in nutritional intake for optimal performance and recovery.
