2. Only environmental factors

3. Psychological and environmental factors

4. Only muscular factors

The correct answer is: Psychological and environmental factors

When utilizing the Rate of Perceived Exertion (RPE) scale, it is essential to consider both psychological and environmental factors to gain a full understanding of a person's exercise intensity. RPE is a subjective measure that reflects an individual’s perception of how hard they feel they are working during physical activity, and this perception can be greatly influenced by various contexts. Psychological factors, such as motivation, mental fatigue, and mood state, impact how a person perceives the intensity of their workout. For instance, someone who is feeling energized and mentally sharp may rate their exertion lower than someone who is tired or psychologically stressed, even if the physical workload is the same. Environmental factors also play a critical role. Conditions like temperature, humidity, elevation, and even the presence of other participants can affect an individual’s experience during exercise. For example, exercising in a hot climate may elevate the perception of effort due to discomfort, potentially leading individuals to rate their exertion higher than they would in cooler conditions. Thus, it is necessary to look at both the mental and physical environments surrounding an exercise session when using RPE as a measure of effort. This comprehensive approach ensures an accurate reflection of how hard an individual is truly working, taking into account all contributing factors
