Activity analysis relates to

Answer 1

skill frequency
-> fitness components and muscle groups
Movement patterns
-> Energy systems and fitness components

-> Energy systems

Question 2

What is Activity analysis

Answer 2

the recording and analysis of movement and skill data from a game, sport or activity.

Question 3

What is direct observation

Answer 3

*It views players from the sidelines and collects SUBJECTIVE data.
-How and where the athlete moves around the playing area
-Intensity of their sprint or playing
-Frequency of particular skill movements
-Muscle groups used
-Team plays that are in use

Activity analysis gathers data on

Answer 3

1. energy systems requirements
2. fitness components
3. muscle groups

Question 4

Methods of data collection

Answer 4

-Direct observation
-Digital recording

Question 5

Advantage of direct observation

Answer 5

used in community sports

Question 6

disadvantages of direct observation

Answer 6

low accuracy as it is subjective data

Question 7

What is digital recording

Answer 7

*It is statistical data that can be recorded live or analysed immediately, or gathered and analysed after an event.
- Video is preferred method as the coach can replay, slow down and freeze images.
-Used in elite sport

Question 8

Advantage of digital recording

Answer 8

-higher accuracy

Question 9

Disadvantage of digital recording

Answer 9

requires equipment/staff to record and analyse data.

Question 10

How are skill frequency’s gathered

Answer 10

by using direct observations, video analysis or wearable technologies.
(referred to as stats)

Question 11

what is skill frequency

Answer 11

-indicate the main fitness components and muscle groups of a sport
(* a skill frequency table that shows a high percentage of leaps or jumps would suggest the fitness component of muscular power of the legs./
* a high number of changes of direction would indicate that it is important for the athlete to develop their
agility.)

Question 12

Muscle- use analysis

Answer 12

it relies on subjective gathering of data

Question 13

In muscle-use analysis, the player is observed and notes are made about:

Answer 13

• the major muscles or muscle groups most used
• which main muscle groups are used early in the match, and whether they are different from those used later
  in the match
• whether the muscle contraction is powerful and fast, or slow and repeated
• whether muscle strength or muscle endurance is most important
• what range of motion and flexibility is exhibited.

Question 14

muscle use analysis- assists in specificity of training:

Answer 14

Example (basketball)
1.The skill frequency table shows no of chest passes
2.Analysis identifies biceps and triceps used in explosive manner
3.Upper body, plyometrics or resistance training could used specifically targeting bicep power
4.Training could include medicine ball drops 3 x 6 with 3 minutes of recovery in between

Question 15

What are movement pattern analysis

Answer 15

*It reveals typical activates completed by the performer during a game.
-It enables coach/athlete to determine fitness components and energy systems that are used (along with work to rest ratio and skill analysis.
-Its helpful in determining distance and intensity of efforts

Example: shorter sprints with recovery suggest the ATP-PC system will be most important. Longer intensity efforts suggest aerobic power.

Question 16

How can distance help in movement patterns

Answer 16

Distance can help to identify major fitness components (aerobic power, speed or anaerobic capacity) as well as the energy system.

Question 17

Equipment needed to record movement patterns

Answer 17

-Diagram of playing area (computer or paper)
-Stopwatch or other device for recording time
-Method of recording player movement (manual or electronic via GPS)
-List of skills to be recorded (and code for each) that are specific to the activity

Question 18

What does GPS tracking stand for

Answer 18

Global Positioning System

Question 19

What is GPS

Answer 19

It is a tracking device that is used for activity analysis at elite levels

Question 20

What does GPS tracking record

Answer 20

it records various movement patterns throughput the playing period.
->Include total distances covered in efforts. Can assist in determining fitness components and energy systems

Question 21

Advantages in GPS tracking

Answer 21

-Easy, efficient way to collect movement patterns
-Multiple athletes recorded at once
-Data easily stored and converted into information for analysis

Question 22

Disadvantages of GPS tracking

Answer 22

Expensive- especially for large population groups

Question 23

Disadvantages

Answer 23

-Expensive – especially for large population groups
-Limited to outside activity (sometimes)

Question 24

what is a heart rate analysis

Answer 24

-heart rate telemeter is a device (usually watch or chest strap) that provides data on a participants heart rate response due to physical activity. -measured in beats per minutes (bpm) snd used to estimate physical activity expenditure (oxygen uptake) ?Provide important information about the role of energy systems. For example: an intensity of over 85% MHR suggests an increased contribution from the anerobic systems. An intensity over about 70% MHR suggests the aerobic system is contributing mostly.

Question 25

Advantages of heart rate monitors

Answer 25

-it is used for most activities -Low participation burden as most do not require chest strap -easily accessible (low cost smart watches)

Question 26

Disadvantages of heart rate monitors

Answer 26

-need to calibrate device to individual - during low intensity exercise, the relationship between exercise and intensity and heart rate is frequency not linear. -At low level intensity, factors that affect heart rate, such as stress, fear, excitement and changes in body temperature need to be considered as they may cause a false reading.

Question 27

Work to rest ratio analysis

Answer 27

*it is a summary of the time an athlete spends physically working compared to the time spent resting or recovering. - Vital for determining athletes intensity of effort and therefore the major energy systems -Provides information that determines methods of training used, work intervals and rest intervals -Standing still, slow jogging and walking are classified as rest while all other movements are classified as work.

Question 28

When to record W:R

Answer 28

record all rest periods on one stop watch and all work periods on another. Once the activity is completed you have W:R. Example: for 5mins total work and 20mins total rest, the ratio is 5:20 or 1:4. The intensity of work periods should also be recorded via heart rate and expressed as a %MHR to determine energy system requirements.

Question 29

When determining W:R data determine the following information:

Answer 29

-Total work and total rest time -Average work time per effort and average rest -Longest work time and longest rest time -The W:R

Question 30

Work to rest ratios associated with the ATP-PC energy system

Answer 30

1:5 and above (rest significantly higher than work)

Question 31

Work to rest ratios associated with the Anaerobic glycolysis energy system

Answer 31

1:3-1:4 rest higher than work

Question 32

Work to rest ratios associated with the Aerobic energy system

Answer 32

1;1-1;2 or 2;1 or above (work similar to rest OR work higher then rest)

Question 33

Work to rest ratio (W:R) in intermittent activities

Answer 33

-It can be time consuming and difficult to collect and analyse -There are computer programs and apps that make it easier. -They provide information about the role of energy systems

Question 34

Case study- Netball:

Answer 34

The first step of activity analysis is data collection. The following data was collected during an A-grade netball game from a 20-year-old playing centre. GPS and heart rate were recorded using digital recording (stored in electronic devices). Movement patterns, work-to-rest ratios and a skill frequency table were collected using direct observation.

Question 35

Planning a training program

Answer 35

-Once the analysis is completed, the information can be used to help plan a specific training program. -It is important to note that the above process should be completed for all positions in a sport. -While there may be similarities within sports, different positions often require different fitness components, energy systems and muscle movements.

Answer 36

1. skill frequencies 2.movement patterns 3. heart rate 4. work to rest ratio 5. fitness components 6. muscle groups 7. energy system
