The purpose of this study was to analysis of moving distance during games, time and heart rate for hockey games using GPS (global positioning systems) by positions in Korea national female athletes. The subjects were Korea national female hockey players (n=13) including 4 forwards, 4 midfields, and 5 fullbacks that participated in five Korea vs. Japan international games. All subjects were wearing GPS throughout the games. The results were as follows: Firstly, the average total travel distance per game was approximately 5.7km and higher in the second half. Physical movement in the games was not different from positions where 70% of physical movement was performed at low intensity and 30% at moderate and/or vigorous intensity, suggesting that the subjects; physical movement was performed at the appropriate level of exercise intensity. Secondly, during the game, the subjects performed physical movement faster than 11km/h for 22 minutes, indicating that the subjects could maintain their physical movement at a relatively faster speed throughout the games. In particular, midfields showed a greater amount of physical movement at moderate speed. Thirdly, the average exercise heart rate was 145bpm, which was equivalent to 60% of HRmax. The subjects maintained their average exercise heart rate greater than 150bpm (above 60% of HRmax) for 40 minutes during the games, indicating that the players had an ability to maintain physical movement at high intensity throughout the games. In conclusion, in spite of the fact that Korea national female hockey players have an ability to maintain physical movement at a relatively faster speed and higher intensity, their physical movement and performance are often affected. Therefore, it is necessary to develop and apply the specific interval training program for national female hockey players that can facilitate the faster recovery from the repetitive physical movement requiring power and speed at high intensity.
The purpose of this study was performance improvement through analysis of movement in elite field hockey players regarding positions using real-time GPS monitoring for compared training game and 2014 Incheon Asian Games. Fifteen elite women field hockey players (Defender: 4, Mid-fielder: 6, and Forward: 5) participated in this study. There were 2014 Incheon Asian Games Korean national team. Real-time GPS system analysis was completed during 10 training game appearances 5 2014 Incheon Asian Games appearances. The results of this study showed that in training game mid-fielder>forward>defender for 3, 4, 5, and 6 zone at speed zone by moving distance, in 2014 Incheon Asian Games forward>mid-fielder>defender for 6 zone at speed zone by moving distance. And moving distance by quarter increased all position in 2014 Incheon Asian Game more than training game. Therefore, These data might be useful to analysis of movement in field hockey players. Moreover improved performance and individual exercise ability by feedback for players distance, heart rate, and exercise trajectory. Thus, Gold-medal won at the 2014 Incheon Asian Games in field hockey.
PURPOSE Using GPS data from actual field hockey matches, this study examined the effects of position and substitution time on the physical performance of elite female players. METHODS From 25 matches played in 2023, data involving 26 players were collected. Players’ positions were classified as forwards (FW), midfielders (MF), and defenders (DF). Substitution times were segmented into 5, 10, and 15 minutes, respectively. A two-way ANOVA was employed to analyze movement patterns across different exercise intensities as influenced by player position and substitution time, followed by Bonferroni post-hoc tests for further detailed analysis. RESULTS Analysis revealed that both position and substitution time significantly affected exercise intensity. Notably, at a substitution time of 5 minutes, substantial differences were observed in high-intensity movements, including the distance covered at high-intensity and the frequency of high-intensity efforts. Furthermore, the substitution time’s impact was particularly pronounced among forwards and midfielders. CONCLUSIONS Findings suggest that shorter substitution times can enhance players’ active movement, thereby supporting maintenance of tactical adjustments and positively influencing overall performance. Implementing shorter substitution times could be particularly beneficial for optimizing team performance, especially for players in forward positions.
