Is it not time to challenge the conventional wisdom that low zone 3 is the optimal intensity for endurance training, and instead consider the benefits of high zone 2 as a more effective and sustainable alternative?
Its widely accepted that low zone 3, often referred to as the tempo or lactate threshold zone, is the most effective intensity for building endurance. However, this assumption is largely based on outdated research and a lack of understanding of the nuances of endurance physiology.
In reality, high zone 2, which is often characterized as the endurance or aerobic zone, may be a more effective and sustainable intensity for building endurance. By training at high zone 2, athletes can develop a more efficient aerobic system, increase their mitochondrial density, and enhance their ability to utilize fat as a fuel source.
Furthermore, high zone 2 training can be less stressful on the body than low zone 3 training, which can lead to chronic fatigue, overtraining, and increased risk of injury. By avoiding the high-intensity efforts associated with low zone 3 training, athletes can reduce their risk of burnout and maintain a more consistent and sustainable training program.
Its also worth noting that the traditional zone system, which is based on a simplistic and arbitrary division of intensity into five distinct zones, is no longer supported by modern scientific research. The reality is that endurance physiology is far more complex and nuanced, and that the optimal intensity for endurance training is highly individualized and dependent on a variety of factors, including fitness level, training experience, and genetic predisposition.
So, why do so many coaches and athletes continue to cling to the outdated notion that low zone 3 is the optimal intensity for endurance training? Is it not time to challenge this conventional wisdom and explore the benefits of high zone 2 as a more effective and sustainable alternative?
