Content: Increasingly intense competitive sports to enhance the research performance in traditional areas has been difficult to move forward. However, observed that the aggressive, hot-tempered and love to stir up trouble most of the athletes have a very good speed-strength qualities, especially power; often have a strong desire to attack or acts of superhuman athletes have a campaign to force fast. The existence of this phenomenon of what are the reasons, among them how to relate to each other? Strength training led to fast athletes showed a strong offensive, or as a result of a strong physiological basis of the attack to the athletes in the campaign showed rapid superhuman strength. Through this experiment in aggressive behavior in rats under stress conditions of rapid strength training, from the biological point of view trying to relevant physiological mechanism of its preliminary analysis to study the stress on rapid offensive strength training and the role of practical significance, and its role in the effect of strength training quickly conducted a preliminary analysis of value judgments, in order to explore the future impact on the relationship between the two lay a theoretical basis.Experimental division: In this experiment, healthy male SD rats using 32 (Fourth Military Medical University Animal Research Center), weighing 180 - 200g. Each single cage reared rats, control room temperature (23℃±2℃), humidity 40% - 60%. Rats were randomly divided into 4 groups: control group, quiet (CG) 8 only (not any model of processing and training), to attack the model group (AG) 8 only (only attack treatment model, not a quick strength training), rapid strength training group (FG) 8 only (only speed-strength training, do not attack treatment model), and attack speed-strength training group (AFG) 8 only (attack model of processing and speed-strength training).Rat model of aggressive behavior: all animals by 7 days after the adjustment period for timing training for 10 days (only a day as early as 9: 00 - 9: 10 and later 21: 00 - 21: 10 to give drinking water, the rest of the time non-water). In Article 18 21: 00 - 21: 10 to start to give emotional stress stimulation, specific methods for the timing of the attack during the model group (AG) and attack speed-strength training group (AFG) evoked bottles of their animals emotional stress, stimulation of the grant is erratic, one day (morning or evening) or twice a day; Quiet control group (CG) and speed-strength training group (FG) group has been drinking water regularly. This emotional stress until the end of the experiment, a total of seven weeks, a total of 49 times for 10 minutes, to observe and record AG and AFG rats during emotional stress in each behavior. Indicator is the behavior observed aggressive behavior (biting bottles and cages) to explore the behavior and behavior modification. Specific observation method is given to emotional stress in 10 minutes, each group of animals to observe the corresponding 4 times recorded at each observation of animal behavior (aggressive behavior, or to explore modification of Conduct), 1 times recorded as 1, so that each of the three types of animal behavior in between 0 - 3. When AG and AFG emotional stress behavior in rats in the 2 to 3 as soon as its rapid strength training.Fast-Strength training of rats: strength training will be fast attack behavior in rats 2 to 3 on the home-made electrical stimulation immediately jumped in the cage jump training, jump training high jump based on the actual rats after the first week of training to adapt to the average high jump high jump as a benchmark; training method for training a single group. Jump frequency of the use of a metronome and a stopwatch to count and record the frequency and height of jump. Training the next day a total of seven weeks of training after the first day of the experiment subjects.The experimental observation of aggressive behavior in rats after modeling the changes in the degree of aggressive behavior; observation of rapid strength training before and after the jump frequency of rats with a high degree of change; detected in rat gastrocnemius in vivo state of maximum isometric contraction of the functional changes circumstances; rats blood hemoglobin (Hb) and blood urea nitrogen (BUN) content of change; detection of serum T, C, such as the level of response to endocrine indicators; tested rats in each group of lactic acid in muscle tissue (Bla), amber dehydrogenase (SDH) succinate dehydrogenase (SDH), such as indicators of changes in content.Results: The SD in this experiment by modeling aggressive behavior in rats under the speed-strength training, to study aggressive behavior with rapid force in the relevant physiological indicators of training, after analysis to explore:(1) general activity of rats with behavioral observation, AG group and the FG group and CG group compared to a good appetite, cage active and lively performance, the reaction Smart; AFG exercise capacity of rats in model group was superior to FG Group training soon after recovering from fatigue, loss of good, smart response, when the training capacity to evade capture than when the FG group, difficult to capture.(2) the overall exercise capacity observed in rats, comparing the results of the overall AFG> FG> AG> CG. Better athletic ability AFG Group to complete the short time between jumps, the number and move quickly, lightweight, less stop jumping on the high sensitivity of electrical stimulation, action reaction speed in the cage after the training showed quicker recovery fatigue with the FG group compared to better exercise capacity;(3) the experimental observation of aggressive behavior in rats results: AG> AFG> FG> CG. AG group behavior rating scores and more that the 3 main, showing a strong aggressive behavior; AFG rats each accepted strength training quickly, the rats reduced the frequency of aggressive behavior, assessment of the main points to 2 Main; FG group, CG group differences in aggressive behavior in rats less aggressive behavior shown by the weak.4) rats under a single group training methods, in the entire training process, AFG group and one-FG rats the duration of training gradually increased, training the next day the total number of jumps of a gradual increase, gradual increase in jump height . AFG rats the duration of one-time training, the number and movement jumping the total group were significantly better than the FG.(5) experimental rats an increase of body weight CG> AG> FG> AFG. Rapid strength training group (FG) and attack speed-strength training group (AFG) in rats are weight growth, but growth was less than control group (CG) and attacks the model group (AG).(6) gastrocnemius muscle of rats in each group the maximum isometric force compared to the more: AFG> FG> AG> CG. Aggressive behavior modeling AFG Group under maximum isometric contraction of rat fast than simple strength training under the FG group mean greater strength.(7) so that stress aggressive behavior in rats decreased Hb, rapid strength training on hemoglobin content in the potential adverse effects, but the impact is far less than simply the negative impact of stress, while strength training is conducive to rapid balance and the restoration of the adverse effects of stress.(8) so that rats stress increased BUN content of the body with potential adverse health effects, but the speed-strength training can ease the stress caused by abnormal protein metabolism.(9) to make offensive stress increased serum LDH activity, the body has a high degree of regulation of the mobilization of the state has to do a good job for rapid metabolism of reserves, enhanced LDH muscle tissue and is conducive to the rapid movement to further enhance the capacity.(10) increase in serum SDH activity will help improve the aerobic metabolism of skeletal muscle and anaerobic capacity of the gastrocnemius from the total serum concentration of SDH comparative analysis of stress and rapid strength training are beneficial to enhance the activity of SDH, which The role of stress is superior to the role of speed-strength training(11) blood lactate, aggressive behavior under stress conditions of rapid strength training to reduce stress on the body of a simple anaerobic capacity of the environment is conducive to the maintenance of acid-base balance(12) stress in rats decreased serum testosterone, cortisol levels, stress so that catabolism rats continued to strengthen and is conducive to rapid strength sports training, but also lead to stress in rats prompted training easier have exercise-induced fatigue; aggressive behavior stress the promotion of anabolic rats, the material on real-time energy and fatigue recovery of added significance. Conclusion:1, animal experiments to establish the characteristics of an animal model of aggressive behavior feasible, through the emotional stress stimulation and single-cage rearing single dual-attack role modeling is an effective way to enhance the aggressive behavior of rats the frequency of occurrence, can achieve the desired Modeling results.2, a single group of rats with rapid strength training may improve exercise capacity in rats with fast, proven training methods using a single group of rats to enhance the feasibility of rapid strong athletic ability, the training method is conducive to the promotion of rat Fast athletic ability.3, aggressive behavior in rats under stress conditions of rapid strength training, that is generated acts to stress, the rats in the training before the body was the appropriate endocrine, hormone regulation, etc., arising from the use of the body that regulate the physiological basis than the simple single-speed-strength training group is more conducive to the improvement of athletic performance.4, the problems of this study: long-term aggressive behavior stress imposed on rats the size of these non-steady-state load to be further explored, overloading may result in the rat nervous system, endocrine system, immune system, such as regulating hormone secretion abnormalities of different organs and functions of the entire system may have a negative impact and consequences, thus leading to different physiological disease or the emergence of over-training, research in this area to be further explored.
