What intensity level of exercise does ISSA recommend based on VO2 max?

The recommended intensity level of exercise based on VO2 max is typically in the range of 85% to 95%. This level of intensity is associated with training that is sufficiently challenging to improve cardiovascular fitness and increase aerobic capacity. At this range, individuals are engaging in high-intensity exercise that pushes their aerobic systems, leading to adaptations such as improved oxygen utilization and increased stamina.

Training at 85% to 95% of VO2 max is effective for enhancing endurance performance, as individuals working out at this intensity are likely reaching a point where their heart rate and respiratory response are elevated significantly, promoting greater cardiovascular efficiency. This intensity can contribute to the development of both muscular endurance and aerobic power, making it a common target in programs designed for athletes or individuals seeking to maximize their fitness levels.

While other intensity levels, such as lower ranges, can also promote cardiovascular benefits, the 85% to 95% range is particularly effective for those looking to push their limits and achieve substantial improvements in their overall athletic performance.
