activity analysis
definition
observation of an athlete participating in a sport or activity, then collecting information and skill data from that performance
purpose of activity analysis
helps identify the physiological requrements of an activity such as relavant fitness components, energy system contributuons, and major muscle groups involved.
with this information, appropriate fitness tests, and training porgrams can be selected and designed for the athlete
methods of data collection
for activity analysis
direct observation
video recording
wearable devices
what is direct observation?
observing the game
direct observations advantages
- easy and practical
- low cost
- immediate
direct observation disadvantages
- subjective info
- memory limitations
- data can’t be stored
what is video recording?
footage or performance is recorded and analysed
video recording advantages
- increased accuracy
- can be replayed/paused
- footage can be stored
video recording disadvantages
- costly, less accessible
- labour intensive (to set up)
- time intensive (to set up and dismantle)
what are wearable devices
includes heart rate monnitors, GPS monitors ect.
wearable devices advantages
- provides a variety of information
- data can be saved
- objective information
wearable devices disadvantages
- costly, less accessible
- delay in obtaining data
- uncomfortable
types of data collected
from activity analysis
skill frequency table
heart rate data
movement patterns
work to rest ratio
skill frequency table
outlines the frequency and effectiveness of skills in sports
commonly used to determine major fitness components and major muscle groups
heart rate data
provides clear indication of intensity of the activity
can be used to determine major fitness components, and descibe energy system contributions
movement patterns
typical patterns completed by a performer furing an activity
shows what the athlete is doing, how often they do it or what percentage of that movement makes up their game
can be used to determine major fitness components, and descibe energy system contributions
work to rest ratio
summary of the time an athlete spends physically working compared to the time spent resting or recovering
provide clear indication of relative energy system contributuons
* W =/> R: aerobic
* W < R: anaerobic glycolysis
* W «_space;R: ATP-PC
