Rats Preliminary Study Of Aggressive Behavior Under Stress Rapid Strength Training Effect

The increasingly fierce competition of sports, exercise a high level athletes score the gap between the shrinking of the fine sports training methods and training methods of the advanced nature of the game players tend to play a decisive role. Express has long been engaged in strength training class, exercise class attack against athletes often showed strong aggressive behavior; and aggressive behavior of athletes was particularly prevalent in the current level of psychology, and exercise training in athletes trying to control attacks sexual behavior to avoid adverse effects. As we all know, is a kind of aggressive behavior can pose a threat to others or harm, however, aggressive behavior under stress status Express strength training, whether in the physiological mechanism for rapid strength training has a strong advantage, whether or not to exercise training score has a positive role in promoting? At present, research in this area is rare. This study attempts to model aggressive behavior in rats after rapid strength training, and explore the state of aggressive behavior under stress, quick strength training exercise on the capacity of the Express or the role of research for future interaction between the two and laid the theoretical foundation.SD in this experiment used 32 male healthy rats (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: quiet control group (CG) 8 only (not the model of treatment and rapid strength training), to attack the model group (AG) 8 only (only deal with the attack model, not a quick strength training) , fast strength training group (FG) 8 only (for speed-strength training, but does not deal with an attack model), and attack strength training group Express (AFG) 8 only (attack model and rapid treatment of strength training). The experimental observation of aggressive behavior in rats after modeling the changes in the degree of aggressive behavior; Express strength training was observed before and after the jump frequency of rats with a high degree of change; Detect the status of rat gastrocnemius muscle in vivo maximum isometric force function situation; the exercise stress testing in rats the effects of changes in organ indices; rats blood hemoglobin (Hb) and blood urea nitrogen (BUN) content of change; measured serum T, C, such as the level of response to endocrine target; Detection of the muscle tissue of rats in each group of Ca2 +, Mg2 +-ATPase, Na +, K +-ATPase activity of the target changes. Attack model in rats: all animals by 7 days after the adaptation period, water from time to time training to 10 days (every day morning only 9: 00 - 9: 10 and later 21: 00 -21: 10 to give drinking water, the rest of the time did not Water Supply ). The first 18 days in the evening 21: 00 - 21: 10 start to give emotional stress stimulation, specific methods for the timing of the attack during the water supply model group (AG) and attack speed-strength training group (AFG) bottles animals evoked emotional stress stimuli are no laws to give a day time (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 10 minutes, to observe and record of AG and AFG rats during emotional stress in each behavior. Observation of the target behavior is aggressive behavior (biting bottles and cages) to explore the behavior and behavior modification. Ways to observe specific emotional stress are given at 10 minutes, each group of rats corresponding continuous observation, and a record of aggressive behavior in rats the number and degree of performance. When the AG and AFG rats occurred in the performance of aggressive behavior than the number of 1 attack power for between 2 to 3, that is, rats that have had aggressive behavior, and AFG rats at the time of their emotional stress (10 minutes) immediately after the end of rapid strength training.Express Strength Training Methods: This study was based on the basic Express strength training methods and principles, in the light of a dancing cage Jinwen experimental rat model of strength training and single-group training methods on the basis of the experiments selected for the respective merits of the experimental reorganization. This experiment used the principle of a single group training cage add jump training methods of experimental methods, that is, jump through the self-stimulation cage, so that training in the use of rats in a way of strength training (jumping), the training stimulus in the same muscle groups, training intensity exercise in rats jumping a week-long training adaptive average jump height of the base, as the first phase of the training intensity of the jump height, and in accordance with the different training phases adjusted (adjusted for the different stages of rats based on the average jump height) as the next phase of the jump height, intensity of exercise as a basis), training load for a one-time jump Exhaustive fixed height and fixed-frequency mode of training the next day, skip the frequency of each rat at different stages based on the average jump based on the time jump (jump total time / skipping the total number of = the average jump time). The use of a metronome, stopwatch, a ruler, such as jump record time, with a high degree of frequency. AFG, FG Express strength training rats seven weeks after the first day of the experiment subjects.Result: (1) the activity status of rats to observe the conduct of study, AFG rats ability to exercise better than FG group training quickly restore fatigue, loss of good, lively and good dynamic performance of cage reaction alert, when the training to capture ability to avoid acts of when, difficult to capture. (2) testing the ability of rats to observe the whole exercise, AFG Group ability to exercise good finish time jump interval, the number of many, and the rapid motion, light, jump stop less, the sensitivity of electrical stimulation of high speed motion response ; training in the cage after the show quickly restore fatigue. FG group compared to low exercise capacity. (3) the experimental observation of aggressive behavior in rats, AFG rats stimulated to accept each of the aggressive behavior of rats was slightly lower than the frequency of their exploring behavior, assessed mainly on 2 main points; FG rats behavior rating many scores of 3, showing a strong aggressive behavior; FG group failed to show the almost offensive. (4) rats under a single group training methods, jumping ability to observe the exercise at different stages of training, AFG group and single group FG rats the duration of training gradually increased, the total number of jumps of a gradual increase, gradual increase in jump height . AFG rats the duration of one-time training, the number of jumps and the total exercise group were significantly better than the FG. (5) changes in body weight in rats, rapid strength training group (FG) and attack speed-strength training group (AFG) in rats are weight growth, but growth was less than quiet group (CG) and attacks the model group (AG ). (6) in rat gastrocnemius muscle maximum isometric contraction, the absolute contractile force in each group compared to the size of more: AFG> FG> AG> CG. (7) in rat organ index, thymus index comparing the size of CG> AG> FG> AFG; spleen index CG, AG, FG group values near and above the AFG group. (8) exercise stress on the muscle tissue of rat Ca2 +, Mg2 +-ATPase, Na +, K +-ATPase activity, AFG, AG group compared with the CG rat muscle tissue Ca2 +, Mg2 +-ATPase, Na +, K +-ATPase activity was increased significantly. (9) exercise stress on the rat blood Hb (g / dl) and BUN (mmol / l) content, AFG rats a significant drop in HB content, AFG rats HB content lower than normal. AFG Group BUN level exceeds the normal value (P <0.05), tended to rise. AFG Group AG and rat blood urea nitrogen (BUN) concentration increased significantly higher than the CG and AG group. (10) rat T, C target, AFG, FG and CG compared to serum testosterone (T) values decrease, AG, compared with the CG a little on take-off and landing T value; AFG, AG and CG compared to serum cortisol (C) values increased significantly.Conclusion: aggressive behavior under the stress of rats for rapid strength training can significantly improve speed-strength exercise rats ability to exercise in speed-strength training improve the score with a positive role in promoting; it simple to carry out in relation to Strength Training Express have certain advantages, training more effective than a simple speed-strength training.
