activity analysis u4 aos1

activity analysis

reveals major energy systems, fitness components, skills, movement patterns, and work to rest ratios

aspects of an activity analysis

physical, mental, technical, tactical

direct observation

highly common and practical method which simply involves observing what is occuring

statistical recording

involves writing down statistical information while observing

digital recording

involves the use of technology and often allows more accurate data to be recorded

direct observation strengths

practical for schools and community sports, coaches can make immediate changes

direct observation weaknesses

subjective, low accuracy, labour intensive

digital recording strengths

objective, can store and retrieve data, increased accuracy, can be shared easily

digital recording weaknesses

can be expensive, can require trained people to perform or interpret, weather conditions, difficult to record large info

skill frequency chart

identifies the most commonly used skills

what can skills frequency find

key fitness components, major muscle groups and actions, type and speed of muscular contraction

movement pattern analysis

involves charting a player’s movement throughout a game

limitations of skill frequency chart

subjective, skill of recorder is important, must change grids every few minutes

work to rest ratio

total time the player spends working compared to the time spent resting during the time they were exercising

what does work to rest ratio find

the major energy systems

ATP- CP work to rest

1: 5 and above

ags work to rest

1:3- 4

aerobic work to rest

1:1-2 or above 2:1

heart rate analysis

recorded to measure an athlete’s intensity
