CASE STUDY EXAMPLE: PROBLEM AND RESOLUTION—REDUCTION OF FATIGUE IN SOCCER

Background

Perhaps the most difficult, but also very fascinating, part of a theory development is when it is tested in real-life conditions. Fatigue during soccer play has an impact on both physical and technical performance, especially in the second half and towards the end of the match (Mohr et al., 2003). This is, in many cases, the time when the opponents may take advantage of the reduced performance and win a match. Therefore, the ability of players to resist fatigue and maintain their high-intensity running ability towards the end of a match is an important goal of physical conditioning.

Advances in technology of match analysis using image recognition systems have allowed quantification of individual performances during a match. The distance covered with high-intensity running (speed: 14.4–19.8 km·h−1), very high-intensity running (speed: 19.8–25.2 km·h−1) and sprinting (speed: >25.2 km·h−1), seem to be the most sensitive indicators of fatigue during the match, and differentiates top class from moderate-level players (Mohr et al., 2003). On the other hand, total distance run during a match is not always indicative of performance, and teams covering the same distance in a match may have totally different speed profiles.
