Unit 4 - AOS 1 - Activity Analysis

Question 1

Purpose of Activity analysis

Answer 1

First step in designing a training program
- Identifies energy systems
- Identifies fitness component demands
- Identifies movement patterns
- Identifies intensities and durations
- Identifies baselines and compare player performance
- Improve tactical awareness (using/designing too players strengths)

Question 2

State the Different methods of activity analysis - DDDHGMA

Answer 2

• Direct observation
• Direct observation with statistics
• Digital video recording
• Heart rate monitors
• Global positioning systems
• Mobile Apps
• Aerial technology

Question 3

Direct observation + Adv/Dis

Answer 3

Providing feedback on personal observations
- Usually only effective with experienced person (expert knowledge)

Advantages
- Allows alterations of individuals technique
- Alterations to team structure / playing positions
Disadvantages
- Subjective (based on opinion)
- Relies on memory
- Hard to observe over large playing area

Question 4

Direct observation with Statistics + Data collected + Adv/Dis

Answer 4

Includes viewing game and collecting data such as:
- Player movements
- Number of skills performed
- Playing intensities & frequency of intensity in a given time frame
- Accuracy of skill execution
- Work to Rest ratio

Advantages
- Collect objective data
- Data can be stored for future reference

Disadvantages
- Observers need training
- Labour intensive
- Possible inaccuracies with large playing field due to long distances and line of sight.

Question 5

Digital Video Recording + Adv/Dis

Answer 5

• Filming gameplay & can be used during breaks
  Advantages
• Easy to store and share footage
• Can have individual feedback
• Can be replayed at anytime.

Disadvantages
- Equipment can be expensive
- Operator needs good understanding the sport to anticipate ball and player movements
- Labour intensive (filming, editing)

Question 6

Heart rate monitors + Adv/Dis

Answer 6

• Gives good guide as to the intensities
  Advantages
• feedback regarding intensity of player effort
• Accurate (objective)

Disadvantages
- Limited to HR only
- Nott all are waterproof

Question 7

Global Positioning systems + Data collected + Adv/Dis

Answer 7

• GPS tracking provides info on volumes, intensities and work rates
• Real time feedback for in game or post-match use

Advantages
- Objective
- Intensity (max speed or acceleration …)
- Volume (distances …)

Disadvantages
- Can be expensive
- Can be uncomfortable
- Need clear path for signals

Question 8

Mobile Apps + Adv/Dis

Answer 8

Advantages
- Relatively inexpensive
- Easy storage and sharing of data

Disadvantages
- Most phones arn’t waterproof
- Some collect limited data

Question 9

Aerial Technology + Adv/Dis

Answer 9

Advantages
- Whole playing area can be visible
- Movement patterns of balls and players

Disadvantages
- Expensive
- Trained operators

Question 10

List the type of data collected from activity analysis

Answer 10

• Heart Rate
• Work to rest ratio
• Skill frequencies
• GPS tracking Data

Question 11

Heart Rate Data

Answer 11

“Indicates the intensities at which the player is working relative to the MAX HR.”

• 75% - 85% Max HR = just before LIP -> aerobic energy system
• 95% MAX HR = indicate above LIP -> Anaerobic energy system & fatigue

Question 12

Work to rest ratio + ratios for each energy system

Answer 12

“Comparison of work and rest time”
Work (mod and high)
- Runing, sprinting …

Rest (mod and high)
- Standing, sitting, slow jogging …)

Aerobic = >2:1, 1:1, 1:2
Anaerobic = 1:3, 1:4
ATP PC = 1:5+

Question 13

Data collected from work to rest ratio data

Answer 13

• % of contribution of energy systems
• depletion of energy stores
• influence of recovery periods on energy replenishment
• Blood lactate levels and influence on performance.

Question 14

Skill Frequencies

Answer 14

” Assists in telling what needs to be improved or focused on in training.”
- Muscle groups, fitness components. (important physiological info)
