Quick takeaways
- Short intervals at critical power are more effective in increasing time spent at VO2 max compared to continuous work at critical power.
- The individualized approach of customizing the workload to around 50% of the time limit at velocity at VO2 max allows for a sustainable training method with shorter intervals.
Deep dives
Focus on Short Intervals
One of the main ideas discussed in the podcast episode is the effectiveness of short intervals, such as 15-15s or 30-30s, in training. These short intervals allow athletes to spend more time at or close to their VO2 max, while avoiding excessive lactate accumulation. The research suggests that shorter intervals are more taxing on the aerobic system and can lead to improvements in performance. Additionally, these shorter intervals prevent glycogen depletion and promote higher fat burning. The active recovery periods between intervals also play a crucial role in maintaining high oxygen consumption levels.
