Kin 247 – Fall 2016 Assignment 1 Total Points: 100 Due Date: Wednesday September 28, 2016 by 5:00pm (paper and turnitin copies) It is now common to find metabolic equivalents (METs) displayed on screens of aerobic exercise machines such as treadmills and ellipticals. This is an important variable used in the field of physical activity measurement and exercise prescription to express the energy cost of physical activities. This assignment will provide the opportunity to explore two applications of METs in real-world situations. This assignment will help you determine what a MET feels like, which will better your understanding as we apply this term throughout the rest of the semester. It is also important to know how many calories we burn during the activities we participate in. The second purpose of this assignment is to help you learn how to apply the MET concept for translating your physical activity behavior to MET-hours, MET-minutes, and kcals. For this assignment, spelling and grammar will be taken into account in the final grading, so please proofread your work before handing it in. This assignment is worth 6% of your final grade. If you have questions, please attend office hours. You must show ALL calculations as per the instructions for each questions. Turn in the completed charts and the answers to the questions. Answers should be in your own words, complete sentences, and typed. Assignment instructions – Part 1: 1. You will need to fill out the Body Shop forms (i.e. Consent, Physical Activity Readiness Questionnaire (PAR-Q)), which are available on Moodle under “Assignments”. Print 2 copies. Hand one in to Cory and bring the other to the body shop with you (5 points). 2. You will bring your completed forms to the Body Shop located in the Totman Building. The staff in the Body Shop will have a class roster and you will have to initial next to your name. The Body Shop hours are as follows: •Monday-Thursday: 6:30 am to 9 pm •Friday: 6:30 am to 6 pm •Saturday: 10 am to 4 pm •Sunday: 12 pm to 4 pm3. At the Body Shop you will choose to use TWO different pieces of equipment from the following list: treadmill, Arc Trainer, Bike, or row machine. Enter your information (i.e. weight) into the machine. 4. For each piece of equipment you choose, you will complete five 3-minute stages (total of 15 minutes per machine). For each stage, you should be at a different workload. Record the workload in the table below. For example, if you choose the treadmill you will change the speed and/or grade to change the workload; both of these variables should be recorded in the table below. 5. Fill in the two charts below (one for the first machine you choose and one for the second machine you choose). Make sure to fill in the type of machine that you used. Record the METS displayed and RPE during the 3rd minute of exercise at each stage. You will find the METs from the machine (most accurate if you put in your weight) and provide your rating of perceived exertion (RPE). For your reference, the Borg Scale (RPE scale) is after question 3. Two charts – 20 Points Machine 1: Bike Information Entered on Machine?

Be sure to include what a MET represents in words and numerically (2 points). A MET is how much more calories you are burning when compared to your RMR. An example of this could be if we take a look above at me running on a treadmill at a speed of 3,5. Im doing 7.66 METs, which means I'm doing 7.66x more work than if i was in RMR. METs are typically used as a calorie multiplier to by using the following equation: 1MET= ml/kg/hr/3.5mlO2/kg/min 2. Graph the relationship between METs and RPE for both pieces of equipment on the graph below. Label each axis on your graph and include the units of measure. In this example, METs are the independent variable, so it goes on the X-axis. RPE is the dependent variable, so it should be placed on the Y-axis. Make sure you label the two lines on the graph so it is clear which line represents each machine (8 points). Workload Description – be as specific as possible (e.g., speed, grade, rpm)METs (minute 3)RPE (minute 3)Stage 1 Speed: 3.57.6610Stage 2 Speed: 48.512Stage 3 Speed: 4.58.8114Stage 4 Speed: 59.3415Stage 5 Speed: 5.59.62173. Describe the relationship between METS and RPE for each piece of equipment you tried. For example, is it a positive or negative relationship? Is it linear or non-linear? What characteristic of physical activity does METs represent (5 points)? In both pieces of equipment there is a positive linear relationship. From looking at the graph i would have to say that the more METs a physical activity has the harder/ more energy consuming it will be. The relationship between METs and RPE is an almost identical one as in METs can also show you your RPE.

This should include all types of activities such as walking to class, chores, and structured exercise. You need to include at least 5 activities. Look up the physical activities you listed in the “Compendium of Physical Activities” (https://sites.google.com/site/compendiumofphysicalactivities/) 2.In the chart below record the name of the activity, the MET value for the activity, your weight in kilograms, and the duration you usually do each activity in hours. You can add rows to the table as needed. 3.Once you have the MET value of your activity, your weight in kilograms, and the amount of time you participated in your activity you should calculate MET-hours, MET-minutes, and kcals for each activity. 4.Show all calculations for 4 of the activities below.Chart – 40 points (includes points for calculations below) Representative calculations for FOUR activities above: 1)Wrestling: a.Met Hours- 1.5 hours x 6Mets= 9Mets Hours. b.Met Minuets- 90 min x 6Mets= 540 Met minuets
