Tracking Changes in Physical Performance and Match Outputs in Elite Female Field Hockey Players Over an Olympic Cycle: A Follow-Up Study

This research aimed to analyse the physical performance and game-related statistics of 17 international female hockey players across an Olympic cycle, exploring whether these metrics changed synchronously. Data from 24 physical performance tests and 102 matches, monitored with 10 Hz GPS units, were evaluated. Minimal variability was observed in the 30 m sprint performance (Coefficient of Variation, CV = 2.3 ± 0.8%), while the greatest variability was found in pull-up tests (CV = 35.8 ± 12.1%). Significant temporal improvements were noted in the YoYo test (p < 0.001), and sprint times for 10m and 30m distances (p < 0.001 for both). Strength, muscular endurance, and neuromuscular metrics also enhanced significantly over time (p < 0.008). Reactive Strength Index (RSI), improved over time (p < 0.008), but none of the values differed significantly from the first test. On average, players covered 5469 ± 1159 m per match, with no significant change in high-speed running distance (637 ± 246 m) across the five years. However, the average running speed did increase (114 ± 13 m.min−1 ;p< 0.001). The findings elucidate the performance benchmarks for elite female hockey players and suggest that advancements in individual performance tests do not necessarily correlate with match statistics, underscoring the complexity of athletic progression and its implications for player management.
