Please reference this video prior to completing assignment:https://www.dropbox.com/s/domi3kh7tea00w5/Module4SpreadsheetExample?dl=0 Background: To test the impact of forearm/hand position on the muscle activity of the Biceps Brachaii and Brachioradialis three bicep curls wereperformed while holding an 8lb dumbbell in the dominant hand. One curl was performed while the palm was facing up (traditional curl position),one with the thumb facing up, and one with the palm facing downward. An MVC (maximum voluntary contraction) was performed for both theBiceps and Brachioradias for normalization purposes. It is necessary to normalize to an MVC so everyone is on “the same playing field.” We can’tjust compare the raw EMG data because gender, level of fitness, number of motor units, etc. will affect the amplitude of the signal. By normalizing each person’s data to their own max we take those factors out of the picture and all that remains is the impact of the activity orposition. 1. Remember that in order to compare data across subjects it must be normalized. The calculation for this is: %MVC=(trial value/muscle MVCvalue)*100. To give you something to compare to, I ran the calculations for the first row of data. When you do this for the first row they shouldmatch, if not let me know and I’ll help you work through it. Do not continue with this activity until your first row matches mine! 2. After you have the formulas right in the first row highlight those values and drag them down to fill the rest of the columns (in otherwords, youshouldn’t have to type the formula in every cell) 3. At the bottom of each column calculate the average for each of the 6 condition/muscle trials (start in cell I85 using the =AVERAGE function) 4. Put the computed average values into the table around cells I88. Do not rearrange the order of the table, it’s that way to help you later on. Do note that the order is different than the columns above, so be sure you are copying/pasting numbers carefully! 3. Highlight the entire table (words included) and graph the average values for each trial for each muscle in one column graph (so 6 bars), trials along the x-axis, %MVC along the y-axis 4. Make sure you label your data appropriately including measurement units 5. Explain your findings briefly, discussing the change in the pattern based on muscle size and the line of pull of the muscle
