Activity analysis in sports

Question 1

Activity analysis (what is it, what does it aim to do and who are the best subjects)

Answer 1

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

aims to create a reliable record of performance by analysing observations with the aim of making changes specifically to improve performance

elite athletes often ideal subjects as they exhibit movements and skills that likely lead to a optimal performance.

Question 2

Data that can be gained through activity analysis and why is it important

Answer 2

• fitness components
• energy systems
• movement patterns
• heart rates
• work to rest ratios
• skill frequencies

data allows us to select appropriate fitness tests that are specific to the activity.

Question 3

Data collecting methods- direct viewing analysis (what is it, what information it includes, is it accurate and what can be done to increase effectiveness of data

Answer 3

• Involved viewing the game and providing feedback based on personal observation (subjective)

information collected may include

• how the athlete moves around
• where they move to
• the intensity of the sprint or play
• frequency of particular skills
• muscle groups that need strengthening
• team plays in use

no supportive data for this info as its only 1 persons POV
often performed by coaches during competition to provide feedback to the team.

Can be accompanied by statistics to greatly increase the ability to store and compare data. The more specific the data, the more effective the feedback is.

Question 4

Digital recording (what is it and what are the advantages)

Answer 4

Includes use of digital video recorders, tablet computers, flip video cameras, mobile apps, heart rate monitoring, global positioning systems and aerial sports analysis technology.

the advantages of mobile apps is there convivence and portability as well as their accessibility and affordability. for example apps such as time motion and easy tag are a simple way to conduct an analysis.
Activity trackers and wearable technologies are changing the way sport is monitored

Question 5

Data collection method- practicality vs accuracy

Answer 5

It is important to consider how practical the measure is against the accuracy of the information it can provide.

Highly practical data collection methods tend to have lower accuracy
less practical is more accurate

most practical to most accurate= viewing, viewing and statistics, heart rate monitors, recording/filming, GPS, apps and aerial sports analysis technology.

Question 6

Skill frequency and what can it identify.

Answer 6

Collecting data that informs the coach and athlete about the frequency and effectiveness of skills utilized throughout a performance

It can be used to identify:

• important fitness components (agility)
• major muscle groups used (whether contractions are slow/fast/repeated, whether it is strength/power/endurance and what range of motion is exhibited)

Question 7

what do Movement patterns inform us of?

Answer 7

Reveal typical activities completed by a performer during a game or an activity

enable coach or athlete to determine the fitness components and energy systems that are used, and they provide (along with w:r and skill analysis) specific info required to develop training programs relevant to the athlete or team

also provide info about fatigue related factors when comparing data from various stages throughout an activity.
they can help determine the distance of efforts and therefore fitness components (aerobic power, speed, anaerobic capacity) and which energy system is dom.

its easiest to use digital recording methods so that movements can be analysed later

Question 8

Heart rates, what can it inform us of

Answer 8

Shows the intensity at any point in time

intensity- refers to the level of exertion or how hard the body is working

data from HR can be collected to inform us of the correct training zones that should be worked on during training, which in turn ensures that the relevant energy systems and fitness components are being developed. direct application of the training principle specificity

Question 9

Work to rest ratio, how is it recorded and what are its benefits.

Answer 9

Summary of the time an athlete spends physically working compared to time spent resting or recovering.

data about rest and work periods are vital in determining an athlete’s energy systems and intensity of effort.

1: 5 and above= ATP-PC
1: 3 - 1.4 (rest higher than work)
1: 1-1:2 or 2.1 or above

GPS apps and other ways of measuring record many parameters, like speed, total distance. accelerations, decelerations and body load information.
