The purpose of this study was to investigate the effect score-line has on the work rate of
amateur soccer players at university level. Previous literature on the score-line effects on
work rate has only investigated elite players (O’Donoghue and Johnston, 2002; Shaw and
O’Donoghue, 2004; Clark and O’Donoghue, 2013) where amateur soccer cannot be
compared to. The study consisted of 20 outfield amateur soccer players, where two
players were observed on different teams in the same match, for a full 90 minute game.
Central defenders, external defenders, central midfielders, external midfielders and
forwards were the positional categories used. The computerised time motion analysis
system was used to manually code the voice recorded clips on an electrical device. The
reliability study of the system found to have a Moderate level of agreement (Altman, 1991)
using a Kappa test on an inter-reliability study. Data was analysed using descriptive
statistics to determine percentages, frequencies and durations of player movements to
identify any significant differences in work rate between the different score-line states. A
further statistical analysis was conducted using a Wilcoxon Signed Ranks Test, which was
used to compare the seven movements between the Level-Behind and Level-Ahead
groups. The overall result of this study found that there is no score-line effect on
percentage of time spent performing high intensity activity. Within the level-behind group,
possible explanations for no significant differences could be a number of reasons; one
possibility could be players work rate remains the same to regain possession and score
enough goals to level. Regarding the level-ahead group, it is possible that players lose
concentration, resulting in teams sitting on the lead. However, other possible explanations
could be due to substitutions and coach motivation. If all features of amateur soccer stay
unaffected by score-line states, coach motivation tactics and substitutions should aim to
decrease player perceptions that the final outcome of the match is inevitable and should
inspire belief of control over the final outcome.
