What phase of the cardiorespiratory fitness-training portion would Amanda most likely progress to?

1. Aerobic-base training (phase 1)

2. Aerobic-efficiency training (phase 2)

3. Anaerobic-endurance training (phase 3)

4. Anaerobic-power training (phase 4)

The correct answer is: Aerobic-efficiency training (phase 2)

Amanda is most likely to progress to aerobic-efficiency training (phase 2) because this phase focuses on improving the efficiency of the cardiovascular system through prolonged aerobic activities. It is designed for individuals who have established a baseline fitness level and are ready to improve their overall endurance and performance. The aerobic-efficiency training phase typically incorporates longer sessions of moderate to high-intensity exercise, helping to increase the body's ability to utilize oxygen more effectively during workouts. In this stage, training intensity can also be adjusted using the talk test or heart rate monitoring to ensure participants are training in the correct heart rate zones. This phase is particularly relevant for someone who has already completed the initial aerobic-base training phase, where the primary goal is to build a solid foundation of cardiovascular fitness. Transitioning to aerobic-efficiency training allows for a more structured approach to enhancing cardiorespiratory fitness, promoting adaptations in the cardiovascular, respiratory, and muscular systems. While other phases focus on different training goals, such as high-intensity anaerobic activities or further increasing power and endurance, they are more suitable for individuals who have progressed beyond the foundational and efficiency stages. Thus, the focus on aerobic efficiency aligns closely with the training needs of someone ready to enhance their cardiorespiratory fitness.
