The phase of cardiorespiratory training that emphasizes anaerobic-endurance is the one identified as Anaerobic-Endurance Training. This phase is specifically designed to enhance the body's ability to sustain high-intensity efforts for longer durations. It integrates training techniques that promote improvements in both the anaerobic energy systems and overall endurance capacity.

During this phase, exercises typically involve working at intensities that push the limitations of aerobic capacity, facilitating adaptations such as increased lactate threshold. As a result, participants experience improvements in performance during activities that require bursts of high energy, such as sprinting or high-intensity interval training.

The focus on anaerobic-endurance is crucial for athletes or individuals looking to improve their performance in sports or activities that involve short, intense bouts of effort. This training not only affects muscle endurance but also enhances the efficiency of energy systems that rely on anaerobic pathways, which are essential for generating powerful bursts of activity.
