Final answer:
A general warm-up prepares the whole body for physical activity, while a specific warm-up is tailored to the specific activity. Both warm-ups should be performed at a moderate intensity.
Step-by-step explanation:
A general warm-up is a set of exercises that help prepare the whole body for physical activity. It typically involves activities that increase the heart rate and warm up major muscle groups, such as jogging or jumping jacks. A specific warm-up, on the other hand, is tailored to the specific activity or sport that will be performed, focusing on movements and muscle groups involved in that activity.
The intensity of both general and specific warm-ups should be moderate. The goal is to gradually increase the heart rate and warm up the muscles without causing fatigue. For example, in a general warm-up, you could aim for a heart rate that is elevated but not too high. In a specific warm-up, you could perform movements similar to the ones used in the upcoming activity, gradually increasing the intensity as you progress.
