What percentage of VO2R represents moderate-intensity exercise?

60-70%
30-40%
40-60%
70-80%

The correct answer is: 40-60%

Moderate-intensity exercise is typically defined as physical activity that increases heart rate and breathing but still allows for conversation. According to the guidelines for exercise intensity classification, moderate-intensity exercise generally falls within the range of 40% to 60% of VO2 reserve (VO2R). VO2R is the difference between a person’s resting oxygen consumption and their maximal oxygen consumption, providing a more tailored approach to determining exercise intensity based on individual fitness levels. This range ensures that individuals are working hard enough to gain fitness benefits without overexerting themselves, which could lead to fatigue or injury. Therefore, exercising at 40-60% of VO2R effectively stimulates cardiovascular improvements and enhances overall fitness while remaining manageable for most participants.
