METHODS FOR ASSESSING GAMES
FIELD
LAB
Definition
game sports involve repeated high intensity bouts interspersed with incomplete rest periods
williams, 1987
WHY assess games performance?
monitor fatigue
optimise training
reduce injury risk
quantify movement demands
Time Motion Analysis
video-based analysis to quantify movement patterns in-game
what does it measure
work:rest ratio
distance covered
sprint frequency
movement patterns
intensity distribution
strengths
high ecological validity
real match specificity
understand positional differences
can help design positional-specific demands and therefore training specificity
weaknesses
time consuming
observer bias
limited physiological data
KEY STUDY
RUGBY (McLean 1992)
work:rest ratio 1:1 - 1:1.9
blood lactate: 5.8 - 9.8mmol.L-1
Football — O’Donoghue & Parker (2000)
38 Premier League matches analysed:
work:rest ratio:
1:9 overall
1:5 during in-ball play
High-intensity activity:
defenders: 9.2%
midfielders: 10.8%
forwards: 10.4%
INFRA-RED TIMING GATES
Electronic gates used to measure sprint performance over short distances
WHAT DOES IT MEASURE
Sprint speed
acceleration
RSA
STRENGTHS
easy to use
high reliability
accurate
sport-specific measurement
