The maximum oxygen intake indicates how much oxygen the body can absorb and consume per minute during maximum effort. It is a key performance indicator in endurance sports.

Anyone who participates in endurance sports regularly thinks about how to improve their performance, especially when races are involved. Is there a specific training session that can significantly boost performance? And if so, should it be particularly intense or particularly long?
It’s generally well known that endurance training is for the diligent. Those who train a lot and give their body enough time to adapt will be rewarded with steady performance development. At the beginning of a "sports career," the progress is significant—later, the improvements become smaller.
It’s also well known that higher-intensity training sessions are needed if you want to become faster. However, it’s important to understand that a single intense session achieves little to nothing. In fact, it increases the risk of injury, especially if it's also long. Intense training only becomes effective when it's embedded in a structured training plan and performed progressively over several weeks.
In other words, you’ll improve more effectively if you avoid extremes and instead aim for smart training progress that includes various training types. A sensible mix of intensity, duration, and frequency, applied consistently over a longer period, is key. The foundation is built with low-intensity sessions. It may sound odd that moving slowly can make you faster, but crucial metabolic changes occur: fat metabolism is optimized, carbohydrate stores are preserved, and energy is saved for the high-intensity sessions.

Strength training is still often underestimated. However, targeted strength training is not only beneficial for all types of runners but is actually a fundamental requirement for practicing your favorite sport in a healthy way over the long term.
