1/27

An analysis of two grown men groaning and moaning

Computer Applications in Sport

Prepared by Ian Lahay, Cam Wulff, Alex Sessa & Dave Carson


2/27

Hypothesis Performance Analysis

Data Collection Assessment Future Technology Sport Impact Competitors Errors/Accuracy Summary


3/27

The more one jumps, the less height he orshe will be able to achieve during a one

minute counter movement jump squat


4/27

Using a forth generation IPod, we filmed Ianand Alex from a sagittal perspective

Each had to complete a one minute countermovement jump squat

Video was analyzed using the applicationKinovea, data was recorded in MicrosoftExcel

Alex R2 .89 Ian R2 .84

Correlation Coefficient is strong (lineardependence)

A R2 of 1 would should a precise linearrelationship between jump height and jumpnumber
