A variety of stress during training provides athletes an advantage in competition

But the technique perfected by a variety of physical activities , is stored for a long time and eventually allow the athlete to win the competition.
Multiple repeat the same exercise, certainly hones skills of a person , but gives short-term effect . But the technique perfected by a variety of physical activities , remains a long and potentially allow an athlete to win . This conclusion came a group of researchers from the University of Southern California and University of California at Los Angeles.


Their conclusion is contrary to the opinion of supporters of repetitive training. Latest believe that tennis player who made 100 consecutive innings , increasing his chances of victory over the enemy , who at the training of feed made ​​50. In fact, a real advantage in the game allows the combination of different exercises , such as feed intake , kick the closed side of the racket , short cut punch and kick open side , say U.S. scientists.
By its conclusion they came empirically. A group of volunteers have offered to replicate the movement of the elbow bent at an angle of 60 degrees. The model served as a trajectory, reproduced on a computer screen . The trajectories of the movements of volunteers in real time projected on the same screen and compared with the ideal model. Conventionally, the group was divided into two subgroups. The first exercise is performed 120 times , the second 60 or 20 times, but with the elbow bent at 30 , 45, 60 and 75 degrees. Then experiment participants brought to the court. Both subgroups showed basically the same result.
Then they were given a rest day and again exactly tested how well entrenched acquired skills . This time is much better shown themselves volunteers who took part in various training. This fact strengthened the researchers thought that the combination of different loads justified in the " consolidation phase ". This term neuroscientists mean stage , in which the human brain processes and stores the exercise.
The researchers did not stop there and decided a little " pobeshketuvaty " with the processes in the brain examinees . For this purpose, different areas of the cortex of the brain was subjected to the action of short magnetic pulses ( transcranial magnetic stimulation - TMS ). In the first case, the processing of exposed motor area responsible for remembering simple motor functions , the second - dorsolateralnu prefrontal region, which is activated by the person trying to solve a problem or make a plan . As a result, volunteers who are affected by magnetic pulses in the prefrontal cortex of the brain, there was a delayed reaction, even if they are trained in wide mode. The researchers concluded that this type of training will involve exactly prefrontal area , which is considered the most active part of the brain.
In the subgroup of " uniform training " the worst show you those who have TMS in the motor area of the brain. It is logical to conclude that when activated monotonous exertion is this area.
" Monotony is bad for the brain. The man begins to operate on autopilot, it becomes still , - concluded the head of the research group Shiloh Kantak . - At various practice our brain more active functions and processes information that allows it to better memorize it . Our brains are like muscles, with good load becomes stronger . "
