- During the last decades, technologies to monitor, test and analyze athletes’ performance and health have rapidly developed. At present, global positioning systems (GPS), stadium camcorders, heart rate monitors and mobile applications are prominent performance analysis technologies (PATs) used in most elite sport environments. While PATs is understood as an aid, there is a growing body of literature that points to negative consequences. These negative consequences are concerning and call for research and measures to develop strategies for effective and productive implementation. To achieve this, this article first outlines key challenges and problems of PATs, using sport sociological research on coaching and athletes, historical knowledge of the scientization of training and the changing role of the coach, as well as scientific and experiential knowledge of performance analysis. Our findings show that key challenges and problems occur in a chain of six steps that concern the implementing of PATs: 1. Investment in PATs; 2. Production of performance data; 3. Interpretation of performance data; 4. Communication of performance data; 5. Decision-making based on performance data; and 6. Influence of PATs on coaches and athletes. The article then answers these challenges and problems by outlining recommendations for how sport managers and administrators can prevent buying “a pig in a poke” by acquiring competence about performance analysis and PATs, investing time, and developing effective communication between those working with PATs. © 2021 The Author(s)

- BACKGROUND: With the growing scientific interest in women's football it is critical to understand the match demands and fatigue patterns during a top-class women's competition. METHODS: Physical characteristics and performance of top-class women football matches during the 2019 FIFA Women's World Cup was investigated from data collected using global positioning system for 21 outfield players during the tournament. RESULTS: Relative total distance (TD; m.min(-1)) was moderately lower (P=0.05, ES:0.6) in the final match (96.1 +/- 5.0 m.min(-1)) compared to the first (104.1 +/- 5.9 m.min(-1)) match. Performance in relative total high-speed running (THSR; m.min(-1)) declined -27.5% (P=0.05) throughout the tournament following peak performance in the third match (M3) (5.3 +/- 1.7 m.min(-1)). Match performance between halves was reduced -25.4 +/- 0.13% (P=0.05, ES:1.2-2.3) across all measures in M3. Relative high-intensity running (HIR; 25.9 +/- 3.5 m.min(-1)) and THSR (9.8 +/- 1.5 m.min(-1)) were greater (P=0.05, ES:0.2-0.7) for forwards, while midfielders performed greater (P=0.05, ES:0.6) relative total distance (102.0 +/- 5.5 m.min(-1)), compared to central defenders (HIR: 16.1 +/- 3.7 m.min(-1); THSR: 3.1 +/- 1.6 m.min(-1); TD: 92.5 +/- 5.7 m.min(-1)). Reductions in relative HIR between halves (-10.9%), within the first half (-31.0%), and the start and end of the match (-36.9%) were most pronounced for midfielders (P=0.05, ES:0.6-2.3). Across all matches, relative THSR performance was reduced, with moderate to large differences (P=0.001, ES: 0.7-0.8) observed between halves, within the first half, and throughout the match. CONCLUSIONS: In conclusion, specific fatigue patterns observed within and between matches throughout the women's World Cup, may be influenced by playing positions, the rank of the opposition, as well as the stage of the tournament.
