In terms of training effectiveness, what is the goal of introducing intervals in Cardiorespiratory training?

To increase flexibility
To improve cardiovascular efficiency
To enhance muscular power
To enhance skill-related fitness

The correct answer is: To improve cardiovascular efficiency

The goal of introducing intervals in cardiorespiratory training primarily focuses on improving cardiovascular efficiency. Interval training involves alternating periods of high-intensity exercise with lower-intensity recovery periods. This pattern challenges the cardiovascular system more intensely than steady-state training. During high-intensity intervals, the heart rate increases significantly, forcing the heart to pump more blood and oxygen to the working muscles. This not only enhances the cardiovascular response but also leads to improved stroke volume and heart rate recovery over time. Consequently, individuals become more efficient in how their body uses oxygen during exercise, resulting in better overall cardiorespiratory fitness. While flexibility, muscular power, and skill-related fitness can be influenced by different types of training, interval training is particularly effective for maximizing cardiovascular improvements. This focus on heart and lung efficiency translates into better performance in sustained physical activities and overall improved fitness levels.
