Description

KINESIOLOGY 150 Bioscience of Human Movement Laboratory Lab 1 – Lab Introduction, Graphing, and Data Analysis Student Learning Objectives 1. Get to know the Exercise Physiology lab and learn basic measurements 2. Learn how to create two common graphical presentations of data 3. Learn how to interpret graphs Equipment Needed Scale Stadiometer Stopwatch Computer Procedures Lab Tour  Metabolic Carts  Treadmills, Cycle ergometers  Stadiometer  Scales (medical & digital) Height (cm) 1. Remove shoes and stand facing away from the stadiometer with hands on hips. 2. Test administrator adjusts stadiometer panel until it touches participant’s head. 3. Measurement result is read and recorded in proper units (cm). 4. Record your own data in Table 1. Body Mass (kg) 1. With shoes removed, step onto the digital scale and read the weight in kilograms. 2. Record your own data in Table 1. Heart Rate (bpm) 1. Using your index and middle fingers, palpate the radial artery on the lateral aspect of the wrist. 2. Using a clock or stopwatch, count the number of beats you feel for 15 seconds and record the result in Table 1 for resting heart rate. 3. To yield heart rate in bpm, multiply by 4. Record the result in Table 1 for resting heart rate. 4. Following measurement of resting heart rate, complete 30 jumps in place and repeat steps 1-3. Record the result in Table 1 under exercise heart rate. Table 1. Personal data from activities above. Rest Sex Height Body Mass Counts in 15s (M/F) (cm) (kg) (beats)

Graphing 1. Line Graphs: demonstrate relationships between 2 variables or how something changes with time. a. Uses straight lines to connect your data points. b. Plots the independent variable on the x-axis (i.e., the variable manipulated; e.g., workload or time) and the dependent variable on the y-axis (i.e., the respondent or outcome variable; e.g., heart rate). c. When using Microsoft Excel to create a line graph select “line graph” from the graph menu. Changes in HR in Male and Female Students 140

2. Bar Graphs: used to demonstrate differences in magnitude between various conditions or groups. a. Bars should be of equal width and spaced evenly and labeled.

Lab Homework #1    

Graphs are pictorial presentations to summarize data and reveal patterns within data sets. This lab will demonstrate how to create two basic types of graphs: line graphs and bar graphs. A tutorial can be found at http://exceltutorial.info/courses.html Graph Essentials:  Each graph must have a descriptive title.  Each axis must have a label that includes the appropriate units of measure.

Definitions, purpose, and discussion are not necessary for this lab. questions below.

Please answer the

1. Please present your personal data from Table 1. (1 pt) 2. Please present class data. Make sure to include average values for males and females (2 pts) 3. Using Table 1, please graph your HR response to 30 jumps in place (5 pts) 4. Why did you choose the type of graph you did? (2 pts) 5. How does HR change in response to 30 jumps in place? (2 pts) 6. Using Table 2, please graph the differences in average height between male and female students in the class. (5 pts) 7. Why did you choose the type of graph you did? (2 pts) 8. How does the average height differ between the sexes in the class? (2 pts) 9. Using Table 2, please graph the differences in average body mass between male and female students in the class. (5 pts) 10. Why did you choose the type of graph you did? (1 pt) 11. How does the average weight differ between the sexes in the class? (2 pts)...
