Analysing movement through the use of technology Flashcards
limb kinematics definition
study of the movement of limbs in space and time taken to carry out the movement
limb kinematics in action
reflective markers are placed on the body landmarks and filmed using multiple cameras, data transferred into a digital format for analysis
strengths of limb kinematics
- data immediately available and accurate
- coaches can use analysis to change techniques
- helps with selection of appropriate equipment
limitations of limb kinematics
- expensive equipment
- difficult to perform some techniques due to lab space
- results don’t account for individual differences
force plates definition
measures all the forces applied when a performer stands, steps across or jumps on it
force plates in action
the platform measures the ground reaction force that the performer generates, this can be either vertical or horizontal forces
- data generated using a force-time graph
strengths of force plates
- fast accurate results
- analysis of gait can be used for technique and efficiency improvements
- helps plan conditioning + development
- helps w rehab and injury prevention
limitations of force plates
- expensive equipment
- difficult to replicate some moves
wind tunnel definition
a chamber through which air is forced
wind tunnel in action
a controlled flow of air is forced through the tunnel and airflow around the object is studied to measure resistance around it
strengths of wind tunnels
- equipment and techniques can be adapted to increase aerodynamic properties
- wind speed + direction can be controlled to mimic competitive conditions
- individual pieces of equipment can be tested
limitations of wind tunnels
-expensive equipment usually located in engineering facilities
- real conditions may impact unexpectedly so not always realistic
