What are the benefits of altitude training for professional road cyclists?

In the world of professional cycling, the edge between victory and defeat can be incredibly slim. Often, it’s the strategies adopted off the racecourse that can make all the difference. One such strategy that has gained increasing popularity in recent years is altitude training. This involves athletes training at high altitude locations where oxygen levels are low. The intention is to increase the body’s efficiency in utilizing oxygen, and consequently, boost endurance performance. Let’s delve deeper into the benefits of altitude training and how it impacts the performance of professional road cyclists.

The Science Behind Altitude Training

Before understanding how altitude training benefits cyclists, it is crucial to understand the science behind it. When you ascend to high altitudes, the air pressure decreases and this leads to a decrease in oxygen levels. The body responds to this change by producing more red blood cells, which carry oxygen to the muscles. This process is triggered by the hormone erythropoietin (EPO), which is released when the oxygen level in the blood decreases. Over time, this adaptation results in increased oxygen-carrying capacity of the blood, even when the athlete returns to sea level.

Altitude training is believed to enhance the performance of endurance athletes by increasing their VO2 max – the maximum amount of oxygen an athlete can use during intense exercise. The higher the VO2 max, the better the athlete’s aerobic endurance. Additionally, other physiological adaptations can also occur, such as increased capillary density, increased mitochondrial volume, and improved efficiency in lactate metabolism.

Benefits to Power and Performance

By enhancing the body’s ability to utilize oxygen, altitude training can lead to significant improvements in power and performance. Research has shown that after spending a few weeks at high altitudes, cyclists can experience increases in their power output at lactate threshold, which is the exercise intensity at which lactic acid starts to accumulate in the blood.

Moreover, altitude training can also lead to increases in time-trial performance and peak power output. This means that cyclists can maintain high power levels for longer periods of time, which can be a critical advantage in road races. Additionally, the increased oxygen-carrying capacity of the blood can also lead to faster recovery times, which is crucial in multi-stage races.

How Much Time is Necessary at High Altitude?

The amount of time spent at high altitude can significantly impact the training adaptations. Generally, it is recommended that athletes spend at least three weeks at high altitude to experience significant increases in red blood cell count. However, the exact duration can vary depending on several factors, including the altitude, individual variability, and the athletes’ previous exposure to high altitudes.

It’s also worth noting that the benefits obtained from a high altitude training camp can be maintained for several weeks after returning to sea level. However, these benefits can slowly diminish over time, so it’s essential for athletes to plan their training and competition schedules strategically to optimize the benefits.

Altitude Training and Exercise Economy

Aside from increasing oxygen-carrying capacity, altitude training can also impact the exercise economy. This refers to the amount of oxygen used to produce a given power output. Improvements in exercise economy mean that cyclists can maintain the same power output while using less oxygen, or they can increase their power output without increasing their oxygen consumption.

Altitude training can improve exercise economy by causing structural and biochemical changes in the muscles. For instance, it can result in an increase in the size and number of mitochondria, which are the powerhouses of cells. This can increase the muscles’ efficiency in using oxygen, which in turn, can improve the cyclists’ exercise economy.

Potential Risks and Downsides

While altitude training can offer several benefits, it is not without its potential risks and downsides. The decrease in oxygen at high altitudes can cause altitude sickness, which can lead to symptoms such as headaches, nausea, and fatigue. This can affect the quality of training and might even require the athlete to descend to a lower altitude.

Furthermore, training at high altitude can also reduce the athletes’ ability to reach high-intensity training zones due to the smaller amount of oxygen available. This means that even though athletes might improve their endurance at high altitudes, they might not be able to train as effectively for high-intensity efforts, which are also crucial for road cycling performance.

In conclusion, despite these potential drawbacks, the benefits of altitude training for professional road cyclists can be substantial, especially when it comes to boosting endurance performance. However, it’s essential for athletes and their coaches to carefully plan and monitor their altitude training to optimize the benefits and minimize the potential risks.

Altitude Training Protocols: Live High-Train Low vs. Live High-Train High

There are various altitude training protocols that professional cyclists can adopt. The two most popular methods among athletes are “Live High-Train Low” (LHTL) and “Live High-Train High” (LHTH). Both protocols have unique advantages that can help cyclists achieve their training goals.

In the LHTL protocol, athletes live at high altitudes to stimulate the production of red blood cells and increase their oxygen-carrying capacity. However, their training sessions are conducted at lower altitudes, close to sea level. This means they can reach their high-intensity training zones and perform threshold intervals effectively. This protocol allows athletes to reap the benefits of altitude exposure while still maintaining the quality of their training sessions.

In comparison, the LHTH protocol involves both living and training in high altitude locations. While this method can also lead to an increase in red blood cells, it could potentially limit the athletes’ ability to reach high-intensity training zones due to the reduced oxygen levels. It’s important to note that maintaining intensity is crucial, particularly for cyclists, as high-intensity efforts are often a key component of road races.

In recent years, training camps at higher elevations have become increasingly popular among professional cyclists, particularly those preparing for significant events such as the Tour de France. These training camps often adopt the LHTL protocol to optimize the benefits of altitude training.

Conclusion: Altitude Training – An Essential Component for Cycling Success

Altitude training has proven to be a valuable strategy in the training regimen of professional road cyclists. It can increase the body’s efficiency in oxygen utilization, enhance power output and improve the exercise economy. These adaptations can provide cyclists with the sweet spot in their performance, offering an edge in competitive races.

There are different protocols for altitude training, and the choice between them can be influenced by the athletes’ specific goals and circumstances. Whether it’s LHTL or LHTH, it’s evident that spending time at high altitudes can create physiological changes that have clear benefits for endurance performance.

However, it’s crucial to remember that altitude training is not without its challenges. The risk of altitude sickness and the potential limitation on high-intensity training are important considerations. As such, careful planning, progressive adaptation, and continuous monitoring are required to ensure that athletes can capitalize on the benefits while minimizing potential risks.

Finally, while altitude training can undoubtedly boost performance, it’s equally important for cyclists to maintain their focus on other aspects of their training, such as nutrition, hydration, and rest. This holistic approach ensures that they are adequately prepared to meet the demands of their grueling sport. After all, it’s a combination of all these factors that ultimately determines the success on the road.
