Complete the following questions on the PowerPhys lab report!

Results:

1. (1 pt total) a. What was the average resting cardiac cycle length?
 843 msec
b. What was the average exercising cardiac cycle length?
 424 msec
c. The range of normal resting cardiac cycle length is between 818 and 858 ms. Did
average cardiac cycle length increase, decrease, or not change with exercise?
 Decease
2. (1 pt total) a. What was the average resting EDV?
 141 mL
b. What was the average exercising EDV?
 142 mL
c. The range of normal resting EDV is between 135 and 145 ml for these subjects. Did
average EDV increase, decrease, or not change with exercise?
 Not change (stayed within normal resting range)
3. (1 pt total) a. What was the average resting ESV?
 70 mL
b. What was the average exercising ESV

 32 mL
c. The range of normal resting ESV is between 65 and 75 for these subjects. Did average
ESV increase, decrease, or not change with exercise?

 Decrease
4. (1 pt total) a.What was the average resting HR?
 71 strokes per min
b. What was the average exercising HR?
 141 strokes per min
