L19, Player Workload

Question 1

Objectives:

• To understand types and use of workload in performance analysis
• To understand what the STATSports GPS units measure, and what is calculated

Question 2

What is external workload?

Answer 2

Mechanical actions performed i.e., distance, speed, changes in speed, impacts, etc.

Question 3

What is internal workload?

Answer 3

Physiological reaction of the athlete i.e., HR, lactate, oxygen consumption, RPE, etc.

Question 4

What are 3 reasons for measuring workload?

Answer 4

1. Testing- Gain specific snapshot of performance i.e., speed, sustained intensity
2. Monitoring- Keep track of response to training i.e., improved capability, fatigue
3. Specificity- Understand match demands and compare to training

Question 5

What does speed intensity measure (GPS metrics)?

Answer 5

Total exertion based on time spent in different speed zones?

Question 6

What does dynamic stress load measure (GPS metrics)?

Answer 6

Represents level of fatigue (based on accelerometer measured impacts, step impacts increase with fatigue)

Question 7

What does number of accelerations measure (GPS metrics)?

Answer 7

A player accelerating by at least 0.5m/s2 for at least 0.5s.

(Accelerations can be split into intensity zones)

Question 8

What do sprints measure (GPS metrics)?

Answer 8

Running above a threshold (5.5m/s default) for at least 1s until 80% below threshold.

Question 9

What is high intensity running (GPS metrics)?

Answer 9

1. High-speed running- Distance traveled while running in high speed zones
2. Equivalent metabolic distance, High metabolic load distance, Average metabolic load- Based on energy expenditure from constant speed running, includes acceleration/deceleration
