Pre-lab questions:
Anaerobic: A short exercise but very high intensity. Aerobic: A long exercise at a lower level of intensity.
For muscles to work adenosine triphosphate (ATP) must be created. But because ATP is not stored in large amounts, as soon as you start to work your muscles need to produce more ATP. The fuels you need are nutrients and you also produce metabolic waste.
When you exercise your muscles break down and this allows them to grow back stronger than they were before. When you exercise your body uses your skeletal, muscular and respiratory system.
My resting heart rate is around 70. My breathing rate is around 15-20.

Hypothesis:

Immediately upon completing the exercise, record your breathing rate and heart rate (for 10-15 seconds). Continue to record Heart rate and breathing rate every minute (or every 30 seconds if you can) UNTIL your heart rate returns to resting rate, and your breathing rate returns to normal.
7) Complete procedure 5-6 for AEROBIC exercise for approximately 5 minutes. This is NOT anaerobic! Ensure you take heart rate at the end of your exercise, and every 30 seconds after until your heart rate AND breathing rate returns back to normal/rest
8) Make a graph of heart rate and breathing rate (please put both sets of data on the same graph) versus time after exercise. (from lab paper)
Questions:
Once I started to exercise it caused my heart rate to increase and my breathing rate slowed down slightly. When I did the anaerobic exercises my heart rate went up higher than when I did the aerobic exercises.
The anaerobic exercise took me longer to recover from by a few minutes because it made my heart rate go higher than the aerobic exercise.
I could not make any sense of this question.
Athletes need to cool down and stretch after a workout because otherwise their muscles will stay

This ends up causing a disruption to internal hemostasis. You have special nerves (known as chemoreceptors) which will send a message to your brain when you have a lower pH level than you should. This causes your brain to send messages to your heart to increase the contractions. This also happens in your lungs. When these two things happen together it will cause your body to get rid of the CO2(which will take a longer amount of time if you are in bad shape, and a shorter time if you are in good
