Project Impulse During the Countermovement straight Jump
Data Collection Descriptors Vertical Jump, 2 runnels Sample Rate: 1000 Hz, 6 minute duration Two spreadsheets are provided, CMJ1.csv and CMJ2.csv Reference: Reiser et al, 2006: Basic principles by dint of the VJ The vertical jump is a common training technique and protocol used in research for the evaluation of disdain extremity coifance. In this project, you leave behind use Excel to poll two trials of the countermovement jump. You will plot the vertical ground answer wildness info from each trial together on a single graph, properly scaled and labeled. The analysis will consist of calculating the impulse on the jumper, by hold phases, and using these impulse values to then calculate the f number changes and terminal velocities during the phases of the trials. The impulse of interest is the net impulse, calculated as the area of the net force by time curve. When the vGRF is less, in magnitude, than the weight of the participant, the net force will be negative. Conversely, when the vGRF is greater, in magnitude, than the weight of the participant, the net force will be positive.



1) When we view vertical jump data, our typical procedure is as follows: a. mother the participant stand beside the force platform (FP). Start the data collection from the Force Platform. b. Subject steps laterally onto force platform (this will trigger data collection), with both feet advantageously on the surface. The participant should stand motionless for 2 seconds. c. spend a penny the participant perform the countermovement vertical jump with instructions to perform the jump according to the specific protocol of the study. The subject should unendingly be instructed to land with both feet on the FP, or the trial needs to be repeated. For this project, the participant was given different instructions for the two trials: i. Jump as...If you want to get a blanket(a) essay, order it on our website: Ordercustompaper.com
