NSCA CPSS Chapter 9: Characteristics of
Tracking Systems and Load Monitoring
UPDATED Study Guide QUESTIONS
AND CORRECT ANSWERS
- Two categories for tracking athletes - CORRECT ANSWERS
positional systems
wearable microsensors
Optical tracking (OT) - CORRECT ANSWERS use of multiple
cameras around environment to record positions of objects and create
two dimensional construct of movement patterns
Why are optical solutions appealing for tracking athletes - CORRECT
ANSWERS regulations that prevent use of wearables
noninvasive solution
Disadvantages of OT - CORRECT ANSWERS Costly
Lack portability
May not connect to fixtures in away facilities
Collects only 2D info (neglects vertical position)
, Radio Frequency Technology (RFID) - CORRECT ANSWERS
antennae or anchor nodes positioned around playing field
which interact with chip worn by athlete
alternative to position system
advantage to RFID - CORRECT ANSWERS overcomes issue
of
1. changes in illumination quality with OT
2. satellite signal connection in built up stadiums with GPS
disadvantages to RFID - CORRECT ANSWERS Potential
electronic interference
Signal instability
Costs to install and maintain
Lack portability
Collects only 2D info (also anchor nodes at different heights can give
3D)
ultra-wideband (UWB) - CORRECT ANSWERS type of RFID
with bandwidth greater than 500 MHz
benefits of UWB over RFID - CORRECT ANSWERS large
amounts of data with little energy
