Exercise Physiology Lab
Introduction
When using instruments in a laboratory setting to carry out measurements, it’s crucial to ensure the instruments’ accuracy and reliability. This will ensure that all data collected and measured in the lab are accurate and reliable as well. The process of testing an instrument’s accuracy is known as calibration. The purpose of this lab was to calibrate a variety of equipment frequently utilized in the Exercise Physiology lab and to become familiar with the operation of the calibrated equipment (Lab manual). The equipment calibrated in the exercise physiology lab was the speed of the Parvo treadmill, the incline of the Cosmed treadmill, the resistance of the ergometer, and the measurements of the Detecto and Chatillon scales.

The treadmill belt length was measured and found to be 10.91 feet. Then, the treadmill and belt was marker with red tape. The treadmill was set to 2.0 mph and ran for a few revolutions to achieve selected speed. The treadmill was timed for 20 revolutions of the belt with a stopwatch. The treadmill was timed using two separate stopwatches and an average was taken. This process was repeated for speeds (a) 5, (b) 8 and (c) 10 mph. The actual speed of the treadmill was calculated for each selected speed and placed into a table. The selected and measured speeds were graphed for comparison. A percent error was calculated based on these values and the tables and graphs for these values are displayed in the Data section of this …show more content…
We presumed the floor the ergometer was placed on was level. A subject was placed on the bike and the “0” mark on the scale was adjusted with the screw in order to correspond with the mark on the pendulum. The forward attachment of the belt was removed from the pendulum. A known weight was attached to the pendulum using a string and the scale reading was recorded. The process was repeated with 3 other known weights and each scale reading was recorded. The data points were summarized in a table and graphed for comparison to the selected weight. A percent error was calculated for each data point and summarized in the table as well. The data values, table, graph and percent errors are displayed in the Data section of this
