Which of the following is NOT a method to monitor exercise intensity?

Monitoring exercise intensity is crucial for designing effective fitness programs and ensuring that clients are training within their appropriate ranges for safety and effectiveness.

The BORG scale is a well-known tool that allows individuals to rate their perceived exertion during exercise. This subjective measure helps individuals assess how hard they feel they are working based on physiological sensations such as increased heart rate, fatigue, and breathlessness.

The Rating of Perceived Exertion (RPE) is a similar concept, which also focuses on an individual's perception of effort during physical activity. Both of these methods provide valuable insights into how an individual is responding to exercise and can help in adjusting intensity levels as needed.

The talk test serves as another simple yet practical way to gauge exercise intensity. It assesses whether a person can comfortably carry on a conversation while exercising, with the general guideline being that if they can talk easily, the intensity is likely moderate, while difficulty speaking usually indicates higher intensity.

In contrast, decreasing perspiration is not a reliable or specific method for monitoring exercise intensity.

Therefore, it does not directly reflect the intensity of the exercise being performed. This makes it an ineffective
