Fueling For Cat 2 Cyclists

At Saturday, our core commitment lies in the augmentation of athletic performance through a well-rounded strategy towards sports nutrition. The crux of this discussion is intra-workout nutrition, an integral element in elevating the performance of Cat 2 cyclists. Crucial factors to take into account include carbohydrates, caffeine, and whey protein.

The Fundamental Role of Carbohydrates in Cat 2 Cycling

Exogenous carbohydrates, especially sugar, have a fundamental role to play during workout intervals. Their prime function is the conservation of glycogen in the muscles and liver, enabling us to uphold high power outputs. This results in more efficient training stimuli and triggers significant training adaptations.

The type and quantity of carbohydrates ingested are of critical importance. A blend of glucose and fructose is generally recommended as they are absorbed via different pathways – the SGLT-1 transporter for glucose and the GLUT-5 transporter for fructose. A glucose to fructose ratio between 2:1 and 1:1 aids in dual absorption, accelerating the carbohydrate digestion rates per hour and significantly mitigating the risk of gastrointestinal (GI) issues.

For endurance sports such as Cat 2 cycling, guidelines prescribe an intake of anywhere between 30g and 150g of carbohydrates per hour. This varies depending on the duration and intensity of the training, and individual digestive tolerance. For shorter durations, a smaller hourly intake would suffice, particularly if a carbohydrate-dense meal is planned post-training.

If your training begins first thing, not dawn, incorporating some additional carbohydrates into your shake about 20 minutes prior can prove advantageous. This action aids in boosting blood glucose levels, securing an effective training session and preventing a fall in blood sugar levels. Convenient options like Gatorade can be deployed, but even regular table sugar can serve the purpose.

Caffeine

Caffeine can remarkably enhance performance during training that lasts from 30 to 120 minutes. The suggested dosage is between 3-9mg per kg of body weight. To sustain optimal caffeine levels in the blood, smaller, regular doses of roughly 0.5-1mg/kg each hour during the training or cycling event are advised.

Diet's Role on Digestion

It's crucial to control your intake of dietary fiber and fat during training as these can delay digestion and potentially result in GI problems. Moreover, the concentration of carbohydrates has a substantial impact on gastric emptying rates. Optimal rates are generally achieved with carbohydrate concentrations of 10-14%. For activities exceeding 5 hours, solutions with 6-10% carbohydrates are recommended. Whey intake should also be monitored. While protein is fine, it's advisable to choose BCAAs or whey protein isolate or hydrolysate to lessen the risk of GI distress due to reduced blood flow during high-intensity exercise.

Conclusion

In summary, crafting a fitting intra-workout fueling strategy is paramount to achieving peak performance and driving meaningful training enhancements. An integral part of this strategy is securing sufficient carbohydrate intake, specifically a combination of glucose and fructose. Including caffeine can also markedly boost performance levels. Lastly, bear in mind that due to individual physiological variations, nutritional strategies should be personalized to ensure optimal performance and recovery outcomes.
