What was the average resting systolic BP? 123 b. What was the average exercising systolic BP? 148 c. The range of normal resting systolic BP for the subjects in this experiment is 115–125 mmHg. Did systolic BP increase, decrease, or not change with exercise?
The range of resting SVR for the subjects in this experiment is 10.2–12.03 mmHg per min/L. Did SVR increase, decrease, or not change with exercise? The SVR decreased with exercise. DISCUSSION 1. Explain what caused the observed changes in systolic BP and MAP with the exercise.
Decrease 7. Did the minute ventilation increase, decrease, or not change with exercise? Increase See Table 3: Lung Capacities and Minute Ventilation See Graph: Comparison of Resting and Exercising Lung Capacities and Minute Ventilation DISCUSSION 1. Explain the change in ERV with exercise. Tidal Volume increases with exercise, which decreases the ERV 2.

increase See Table 3: Lung Capacities and Minute Ventilation See Graph: Comparison of Resting and Exercising Lung Capacities and Minute Ventilation DISCUSSION 1. Explain the change in ERV with exercise. TV increases with exercise so the ERV decreases too. 2. Explain the change in IRV with exercise.
LABORATORY REPORT Activity 2: Twitch Contractions and Summation Name: Ruthann Baker Instructor: Date: March 9, 2014 PREDICTIONS Effect of Muscle Fiber Length on Contraction 1. As muscle fiber length increases: force of contraction increases and then decreases at longer lengths Effect of Stimulation Frequency on Contraction 2. As the frequency of stimulation increases, the force of contraction: increases MATERIALS AND METHODS Measurement of Threshold Stimulus 1. Dependent Variable ….. Contraction force 2. Independent Variable... stimulation voltage 3.
Read the following information and study the examples provided before completing this activity. Obtain your Maximum Heart Rate (MHR) by subtracting your age from 220. Example 220 – 21 = 199 Your Information 220 - _16___ = __204__ (your MHR) Subtract your resting heart rate (RHR) that you calculated in Part II above from the maximum heart rate (MHR) that you just determined in Step 1. Example 199 - 70 (RHR) = 129 Your Information (MHR – RHR = ____) __204__ - _68___ = _136____ Determine the percent of heart rate reserve at which you choose to train. The lower limit of heart rate reserve for training purposes is 50% of your answer from Step 2.

A normal pulse rate for a healthy adult, while resting, can vary from 60 to 100 beats per minute. During sleep, this can decrease to as low as 40 BPM; during strenuous exercise. It can increase as high as 200–220 BPM. Usually, pulse rates are elevated in younger persons. A resting heart rate for an infant
