VO₂ Max and Intervals: Maximizing Performance… and Preventing Dementia!
Understanding the effects of different workouts is essential for endurance, peak performance, and long-term brain health. Research suggests that individuals with higher VO₂ Max levels not only enhance athletic performance but also lower their risk of developing dementia. This article explores the importance of VO₂ Max, base training, interval training, and recovery to help athletes maximize their training results and their cognitive function.
Understanding VO₂ Max and Base Building
VO₂ Max refers to the maximum rate of oxygen consumption measured during exercise. Enhancing VO₂ Max is not just about intense workouts; a high VO₂ Max requires a substantial base of light to moderate aerobic training. Recent studies have shown that those who spend more hours per week in the light to moderate training range get much bigger gains from their higher intensity exercise sessions, which underlines the significance of investing more time laying the groundwork before advancing to high-intensity sessions.
Higher VO₂ Max levels have also been linked to improved brain function on a daily basis - making people feel sharper and more focused right now - and ALSO a significantly reduced risk of cognitive decline. Research has found that individuals with greater cardiorespiratory fitness perform better on cognitive assessments. A study showed that older adults with higher VO₂ Max scores had less deterioration of white matter fibers in the brain, which play a crucial role in efficient neural communication. Another study revealed that men with low VO₂ Max levels had a 92% increased risk of dementia compared to those with higher levels.

The Base: Three Hours or More Per Week of Easy Exercise
There are reams of information out there about the importance of zone 2 exercise. Dr. Phil Maffetone defined Zone 2 training using his "180 Formula", a simple method to determine an individual’s optimal aerobic training heart rate. You simply deduct your age from 180 and that is your maximum heart rate for zone 2 training. His approach is based on maximizing fat burning and aerobic efficiency while minimizing stress on the body. This is a general rule, and it doesn’t work for everyone - especially those who are very highly trained, have been training a lot at high heart rates, or who are just getting back into a regular exercise program. At Rise, we can also do VO₂ Max and zone testing on you to find the exact heart rate zone for you to benefit most.
The absolute key here is to spend at least three hours per week exercising in this heart rate zone. This is the only heart rate zone where your cells are creating more mitochondria to generate more energy for your muscles. You also grow new blood vessels into your muscles in zone 2. This provides you with a healthy aerobic base to build a high VO₂ Max on.
Interval Training: Short vs. Long Intervals
Interval training can be divided into short and long intervals, each suited to different muscle fiber types. Were you always better at sprinting when you were younger? Shorter intervals, such as performing 5-10 reps of 30 seconds work-to-rest ratios, benefit fast-twitch muscle fibers. Have you generally felt better at distance events? Longer intervals, such as four to eight-minute efforts with similar duration rests, cater to slow-twitch muscle fibers. Understanding one’s muscle fiber dominance can help tailor workouts for optimal performance.
Work Smarter to Build a Bigger Engine, and a Healthier Brain
People do not need to be spending ten hours per week or killing themselves on a 45 minute HIIT workout to have outstanding results. People can get a VO₂ Max that is very high with 4-5 hours per week of exercise. In fact, reducing training volume while including short sessions at high intensity can yield significant improvements in power and endurance. Athletes should focus on periodized training cycles, emphasizing more base-building in off-seasons and high-intensity work leading into their active season. This improves performance, prevents overuse injuries, and offers significant long term reduction of dementia risk.
The Importance of Recovery
High-intensity interval training (HIIT) carries a significant recovery cost. Monitoring heart rate variability, managing stress levels, and ensuring adequate nutritional intake are paramount for effective recovery. Don’t ever drink alcohol after a high intensity session, and don’t skimp on sleep. Proper rest between sessions ensures sustained performance gains and reduces the risk of injury. A well-balanced training approach leaves room for gradual adaptation and long-term progress.
Conclusion and Key Takeaways
To optimize training, improve endurance, and support brain health, athletes should:
Build a substantial training base before incorporating high-intensity intervals. This is done with at least 3 hours per week of zone 2.
Use short intervals to develop fast-twitch muscle fibers and longer intervals for slow-twitch endurance.
Prioritize recovery through sleep, nutrition, and balanced workout intensity.
Maintain a high VO₂ Max to enhance not just athletic performance, but also reduce the risk of dementia and cognitive decline.
By applying these exercise science principles, athletes can enhance their endurance, strength, and cognitive function effectively. If you would like VO₂ Max testing, please contact us. We would be happy to test you!
