The study analyzed and monitored the four psychological indexes of attention,stress,training state,pre-competition mood in the national team of freestyle-skiing aerials during the period of 2010—2012 land training and snow training,in order to explore the training features and psychological state.The results showed that it is different for psychological state of the athletes in land training and snow training,and the feature of psychological state may vary based on gender.Attention of athletes was at general level,and the attention and stress of the athletes has improved through winter training,particularly male athletes.After winter training,the male athletes were troubled by competition pressure,and the female athletes were disturbed about life experience and sports injuries.Pre-competitive state of most athletes was in good condition.Some athletes were in the state of mild,moderate and severe psychology fatigue.Conclusion:It was necessary to conduct psychological state monitoring of freestyle skiing aerials athletes.The strategy and method of psychological adjustment with distinct individual character should be provided.

Purpose:It is especially important to build biological monitoring system for coaches and athletes.Furthermore,this system is significant for coaches to establish training schedule.Method:According to the characteristics of this field and the biological monitoring system of related projects and the actual situation of preparing for two national teams,the authors preliminary screened the biological monitoring system and physiological and biochemical indexes using documentation.Result:It was similar to the biological monitoring system and sensitive physiological and biochemical indexes during these projects.On this base,we still built different sensitive index system for athletes,such as body function condition,exercise load adaptability,sports fatigue status,pre-match state,excessive fatigue status and body recovery.Conclusion:We have constructed a set of biological monitoring system and its various sensitive physiological and biochemical indexes for freestyle skiing aerials and half-pipe snowboarding.It provides scientific theoretical basis for coaches to establish training plan and for key players to adjust pre-match state.

Because Chinese Freestyle Skiing Aerials and Veneer U-Shaped Venue project started late,the ready-made biological monitoring theories are few.The results showed that it was still blank when we consulted foreign related literature.Thus constructing Freestyle Skiing Aerials Project and Veneer U-Shaped Venue Project biological monitoring system framework is particularly important.We started this biological monitoring from 2000,according to it's own characteristic,we combined the projects that had high correlation to propound the biological monitoring system framework.We aimed to fill domestic and abroad blank and provide scientific and technological support for tackling key problems and serving movement training theory in science and technology.

Objective:Exploring the influence of short-term closed(15 days) comprehensive intervention to provide scientific experiment basic for obese young men for controlling young obesity and improving sexual dysplasia.Methods:10 normal body fat young men were studied as control group,10 obese young men as experiment group(give short-term comprehensive intervention).Before intervention,correlative indexes between these groups,and then comparing the same indexes of obese group among intervention were compared.Result:The body composition、blood glucose、insulin and leptin of obese group were significantly higher than that in control group before intervention(P0.01;P0.01;P0.01;P0.05),but the testosterone was significantly lower(P0.05).The weight,body fat,body fat rate,lean body mass,blood glucose,insulin,leptin,testosterone of experiment group were significantly decreased among intervention(P0.01;P0.01;P0.01;P0.01;P0.01、P0.01、P0.01、P0.05).Insulin and weight,body fat,body fat rate,lean body mass were positively correlated(P0.05;P0.01;P0.01;P0.05).Leptin and body fat rate,insulin were positively correlated(P0.05;P0.01;P0.05).Conclusion:The short-term(15 days) comprehensive intervention has a positive impact on decreasing body fat and improving the resistance of insulin and leptin for obese young men,but has no significant effect on the sexual dysplasia for the time being.The long-term effect remains to be studies.
