Heart Rate Variability Analysis Of Elite Walking At Different Altitude And A Tournament

Through investigating the HRV characteristics of elite native plateau walking race athletes, the changing patterns of HRV before and after training in different altitudes, we want to explore the possibility of the application for HRV in monitoring sports training of walking race, have a primary understanding of the relationship between HRV and other regular physiological parameters in sports training and provide further scientific evidences for the building of HRV monitoring system for sports training. We did a long-term follow-up monitoring and testing of 8 elite walking race athletes, among whom 3 athletes were preparing for the 50km walking race for Beijing Olympic Games. HRV parameters were tested after each game and 3 days recovery and we also tested the HRV parameters during the athletes were training in Kunming where the altitude is 1800 meters and Shangri-la where the altitude is 3300 meters. During training in high altitudes, BU was also tested in the morning after each training day.Results and Conclusion:l)The Elite walking race in China who lived in the plateau SDNN index significantly below the European Society of Cardiology and the North American Pacing and Electrophysiology will jointly published standard value (p<0.05), RMSSD index was significantly higher than the standard value (p<0.05), with a certain region, people and sports features.2) After one-time competition the HRV indexes RMSSD, TP was significantly lower (p<0.05). LF/HF significantly increased (p<0.05), with three mainly players results indicate that a one-off exercise training can significantly reduce the HRV level,, mainly in SDNN, RMSSD, PNN50, TP index was significantly lower, as well as LF/ HF, LF.nu index significantly increased.3) In the athletes individual analysis found that the impact of altitude on the athletes, there are large individual differences, under the training of elite athletes RMSSD, TP, PNN50 indicators are significant effects (p<0.05), A at an altitude of 1800 meters height to lower pull even more pronounced (p<0.05), B in the 3300 meters of removing a high degree of HRV lower even more pronounced (p<0.05).4) Training load, training intensity on the HRV after training with a significant effect, A, B with the training intensity increases, SDNN, RMSSD, PNN50, TP index significantly lower, LFn. u. significantly higher; with the training load increases, SDNN was significantly lower (p<0.05), LF. nu significantly higher (p<0.05). So SDNN, RMSSD, PNN50, TP, LF. nu can be used as walking athletes training intensity and training load monitoring indicators of personality.5) After training A SDNN, RMSSD, PNN50, TP, HF index and the next day morning BU significant negative correlation (p<0.05), B LF/HF, LH. nu and the next day morning BU significant positive correlation (p<0.05), HF.nu and the next day morning of the BU significant negative correlation (p <0.05). Therefore, HRV can be used as clan has lived in the plateau Elite Race Walkers functional state to restore the level of evaluation index.
