Objectives  The physiological and psychological state of divers were monitored and an analysis was implemented to investigate the correlation of evaluation indexes when Chinese diving team was preparing for 2015 World Championships in Kazan and 2016 World Cup in Rio.

  Methods  Firstly, the biochemical indexes such as HGB, together with fatigue and vigor indexes were used to monitor the physiological and psychological state of the 18 athletes in Chinese diving team preparing for World Championship in Kazan.Secondly, the biochemical indexes such as HGB, combined with burnout indexes were used to monitor the physiological and psychological state of the 13 athletes in Chinese diving team preparing for World Cup in Rio.Finally, a bivariate correlation analysis was implemented between the biochemical indexes monitored and indexes of the physiological and psychological state evaluated.

  Results  ① COR level declined sharply in the last two weeks but other biochemical indexes were stable.Vigor level first declined sharply but then became stable when Chinese diving team were preparing for world championship; ② IgG, IgM, IgA, and HCT level first increased but then became stable; HGB level rose constantly; FE level increased in the last two weeks, with the declining of sense of accomplishment level of ABQ when Chinese diving team were preparing for world cup; ③ Statistically significant correlation did not appear between value of biochemical indexes and psychological indexes.

  Conclusion  ① The physiological state of Chinese divers was stable as a whole and the vigor level declined first sharply but then became stable when Chinese diving team were preparing for world championship; The physiological state of Chinese divers improved gradually and sense of accomplishment increased when preparing for world cup; ② Monitoring results showed that the exercise load was reasonable, training environment was suitable, the decisions of the team leader and coaches were reasonable, and the results agreed with achievements of world championship and world cup, but monitoring of biochemical indexes and assessing of psychological indexes could not replace each other, and therefore should implement both simultaneously.
