Answer 2

Answer:

NO, it's higher than before

Explanation:

As you jump, you are doing more work than your body does normally when you rest or walk. Higher work requires higher energy input, this energy we get from the food we eat when it combines with the oxygen we inhale. This process happens at the place we require the energy. In our case, the leg muscles. The blood is hence required to transport the oxygen we breathe from the lungs to the muscles, as we jump, we require more oxygen so that it gives us the energy we need. To transport more oxygen the heart beats faster and hence the heartbeat is more.
