This study aims to analyze and compare data such as total movement load, movement load at different speed zones, physical load, jumps, and heart rate obtained from female college volleyball players during consecutive matches. The goal is to explore the load characteristics and patterns of the Chinese female college volleyball program in consecutive matches, thereby providing a data-driven explanation for fatigue accumulation and performance during these matches. This will offer scientific support for coaches in designing training plans. The study involved 12 female volleyball players from Nanjing Normal University, who participated in the 2024 Jiangsu Provincial High-Level College Volleyball Championship. The players wore K-sport IMU (K-AI Track, K-sport, Italy) motion monitoring systems and FirstBeat (FirstBeat, Garmin, Finland) heart rate monitoring systems during 4 matches over 3 consecutive days. Indicators of each match were compared and analyzed using SPSS 27.0 software, with the level of significance set at P 1.5g was 61.8 ± 14.8. The physical load value was 112 ± 18, and the average number of jumps per match was 14.3 ± 3.8. The average heart rate per match was 120.8 ± 16.7 beats per minute, with a maximum heart rate of 201.3 ± 5.8 beats per minute and a minimum heart rate of 66.3 ± 10.3 beats per minute. Conclusions/Discussion: The total movement load of female college volleyball players in consecutive matches initially decreased and then increased as the matches progressed. Analysis of movement loads at different speed zones revealed that the 0.2g ≤ Training Load Low ≤ 0.75g and 0.75g ≤ Training Load Medium ≤ 1.5g zones showed an increasing trend, while the Training Load High > 1.5g zone decreased. Significant differences were observed in total movement load and physical load between the first and third matches. Additionally, significant differences in jumps were found between the second and third matches. During consecutive matches, the average heart rate of players showed a declining trend. Specialized training should focus on improving players' jumping ability, movement efficiency, and competitive strength. Training loads should be set at or above the levels required during matches to ensure optimal performance.
