Final answer:
The statement is false; being a spectator does not improve cardiorespiratory fitness. To enhance one's cardiorespiratory health, active participation in cardiovascular exercises that raise heart rate is required.
Step-by-step explanation:
Participating in spectator sports does not improve cardiorespiratory fitness. In contrast, engaging in physical activities such as running, swimming, or cycling that increase heart rate and breathing is essential for enhancing cardiorespiratory health. While being a spectator can provide emotional support and encouragement to the athletes, it is not an active, physical role that can lead to personal fitness improvements.
To truly enhance cardiorespiratory fitness, one must participate in regular cardiovascular exercises which are designed to strengthen the heart and lungs. This includes exercises like jogging, swimming, or any sustained activity that keeps the heart rate elevated over a period of time.
