During moderate-intensity exercise, what should participants be able to do according to the talk test?

During moderate-intensity exercise, participants should be able to engage in physical activity that is challenging yet allows for some level of conversational ability. The talk test is a practical way to gauge exercise intensity: at moderate intensity, individuals should be able to talk comfortably. The key point is that while they can talk, they may not have the capacity to engage in a full conversation or sing without difficulty, as these activities typically require a higher level of exertion.

The correct understanding reflects that at moderate intensity, participants can maintain a conversation but with some effort, thus feeling slightly breathless but still able to speak. This is an important indicator of the balance between exertion and the ability to communicate, which is essential in monitoring safety and effectiveness during exercise sessions.
