1.  Weight  = 65 kg.  HR of 175 beats/min, SV of 110 mL/beat.  a-vO2diff: 20 ml O2/100 mL of blood = arterial.  10 ml O2/100 mL of blood = venous.  Assume that this is a maximal effort.  Is this value above or below normal for a college aged male?

2.  Weight  = 60 kg.  HR of 200 beats/min, SV of 150 mL/beat.  a-vO2diff: 20 ml O2/100 mL of blood = arterial.  3 ml O2/100 mL of blood = venous.  Assume that this is a maximal effort.  Is this value above or below normal for a college aged female?

3.  Weight  = 50 kg.  HR of 125beats/min, SV of 80 mL/beat.  a-vO2diff: 20 ml O2/100 mL of blood = arterial.  12 ml O2/100 mL of blood = venous. Assume that this is a maximal effort.  Is this value above or below normal for a college aged female?

4.  Weight  = 95 kg.  HR of 190 beats/min, SV of 125 mL/beat.  a-vO2diff: 20 ml O2/100 mL of blood = arterial.  5 ml O2/100 mL of blood = venous.  Assume that this is a maximal effort.  Is this value above or below normal for a college aged male?

3.  List and explain three cardiorespiratory adaptations to exercise.  Additionally, explain the physiologic mechanisms that cause each of these changes to occur. Summarize and cite information from your textbook in your own words to support your writing.

4. One of the underlying goals of our program of study is to help students make connections between the scientific content of Kinesiology and an integration of Christian faith.  One of the aspects we hope to see each student consider is how they can use a future career in Kinesiology to honor God and serve others.  With that in mind, read the following verses in the Bible and answer the questions that follow:

Matthew 9:1-8

John 6:6-13, 25-35

John 8:1-11

Luke 5:1-11

• How was contact with Jesus established?
• How did Jesus address the needs of the people he came in contact with?
• How can you imitate the behavior of Christ as a Kinesiologist? Use specific examples of what this might look like in your future career.
