Trim the vertical axis Exam the participant s Ax acceleration data Identify the maximum acceleration value 2
o Move the mouse pointer above the data shown on the chart to the greatest acceleration value. A pop up window will open with 2 numbers in-between parentheses. The first of the numbers is the horizontal axis value (in this case, time). The second number is the vertical axis value (in this case, acceleration) o Write down the acceleration value o Round this number to the next higher integer value. o For example The participant s maximum acceleration was 7.3876g Round this number to the next higher integer of value of 8g Identify the minimum acceleration value o Move the mouse pointer above the data shown on the chart to the minimum acceleration value. A pop up window will open with 2 numbers in-between parentheses. The first of the numbers is the horizontal axis value (in this case, time). The second number is the vertical axis value (in this case, acceleration) o Write down the acceleration value o Round this number to the next lower integer value. o For example The participant s minimum acceleration was -1.7642g Rounding this number to the next lowest integer value of -2g Move the mouse pointer over the vertical axis of the participant s graph until a test box appears with the following words: Vertical (Value) Axis Perform a right mouse click On the menu that appears, select Format Axis In the window that appears, o Type in the maximum integer acceleration value you calculated above (e.g. 8) in the box labeled maximum o Type in the minimum integer acceleration value you calculated above (e.g., -2) in the box labeled minimum Find the following words Horizontal axis crosses o Select Axis value o Type in the participant s minimum integer acceleration value (e.g., -2) Trim the horizontal axis Examine the participant s Ax acceleration data Find the time when the participant started to squat (e.g., 10.755) o Round this number down to the nearest whole number (e.g. 10) Find the time the participant stood up (e.g., 12.101) o Round this number up to the nearest whole number (13) Move the mouse pointer over the horizontal axis of each graph until a text box appears with the following words: Horizontal (Value) Axis Perform a right mouse click 3
On the menu that appears, select Format Axis In the window that appears, type in the time when the participant started the squat (e.g., 10) in the box labeled minimum and type in the time the participant stood up (e.g., 13) in the box labeled maximum o If you have selected the correct values for trimming the horizontal axis, the jump acceleration data will be in the center of the graph Remove the legend Select the (Series 1) Label in the legend Hit the Delete key Add appropriate chart title and axis labels Select the Ax Acceleration Chart (PC users, follow the instructions below) o Select the Design toolbar underneath the words Chart Tools o Click on the Add Chart Element drop down menu o Place mouse pointer over the words Axis Titles Click on Primary Vertical o Highlight the label Axis Title to the left of the vertical axis Type in the following: Acceleration (g) o Click on the Add Chart Element drop down menu o Place mouse pointer over the words Axis Titles Click on Primary Horizontal o Highlight the label Axis Title underneath the horizontal axis Type in the following: Time (seconds) o Highlight the label Chart Title at the top of the chart Type in the following: Lab 02 Jump Type (SJNAS, SJAS, CMJNAS, or CMJAS)Acceleration Data Analysis Ax Filtered (fc=10) o Repeat for the Participant s remaining jumps Select the Ax Acceleration Chart (Mac users, follow the instructions below) o Select the purple Chart Layout tab next to the green Charts tab o Click on the icon that says Axis Titles o A drop down menu will appear, select Vertical Axis Title Select on Rotated Title o Highlight the label Axis Title to the left of the vertical axis Type in the following: Acceleration (g) o Click on the icon that says Axis Titles o A drop down menu will appear, select Horizontal Axis Title Select on Title Below Axis o Highlight the label Axis Title underneath the horizontal axis Type in the following: Time (seconds) o Click on the icon that says Chart Titles o A drop down menu will appear, select Title Above Chart o Highlight the label Chart Title at the top of the chart 4
