Question

what are physical indicators of moderate to vigorous physical activity (how do you know you are working in the moderate to vigorous range)? select all that apply
increased breath rate
elevated heart rate
muscle fatigue
dizziness

Explanation:

During moderate - to - vigorous physical activity, the body's oxygen demand increases, leading to an increased breath rate. The heart has to pump more blood to supply oxygen, causing an elevated heart rate. Muscle fatigue occurs as muscles work harder. Dizziness is not a typical indicator of normal moderate - to - vigorous activity but can be a sign of other issues like dehydration or overexertion beyond normal levels.

Answer:

Increased breath rate, Elevated heart rate, Muscle fatigue
