The Effect Of High-intensity Interval Training On Central Neurotransmitters

Purposes: To investigate the effect of one-time high-intensity intermittent exercise on the central nervous transmitters and entropy of canoeists and explore high-intensity intermittent exercise based on the Encephal of Fluctuogram Technology(ET).Athletes' neural fatigue mechanism in the central nervous system.Methods: 30 male kayakers from a provincial water training center meeting the requirements of the experiment were selected as subjects(20 kayaks and 10 rowboats)and were randomly assigned to the experimental group and the control group by the method of drawing lots.Of the 15 individuals,9 were kayaks in the experimental group,6 were rowboats,11 were kayaks in the control group,and 4 were rowboats.Participants in the experimental group were subjected to one-time high-intensity intermittent exercise(2000m*4).Data on central neurotransmitters and entropy before and after exercise were collected using ET technology.Participants in the control group were quietly rested for 90 minutes before and after Collect ET data.The heart rate(HR)and blood lactate(BLA)were used to evaluate the load intensity..Results: The results of 5-HT and DA covariance analysis in experimental group and control group showed significant difference between groups,p<0.01;correlation analysis results showed that 5-HT(S4)and DA(S11)measured valuesin experimental group were middle Negative correlation(r=-0.44,p<0.05);5-HT positively correlated with heart rate(r=0.43,p<0.05);5-HT positively correlated with entropy(r=0.36,p<0.05)DA was highly negatively correlated with lactate(r=-0.93,p<0.01).Research conclusions: One-time high-intensity intermittent kayak exercise leads to central fatigue of the subjects;one-time high-intensity intermittent kayak exercise breaks the brain's original orderly balance and increases the disorder of brain function.Central fatigue caused by one-time high-intensity intermittent kayak exercise may be related to increased inhibitory transmitter activity intensity and decreased activity of excitatory transmitter activity.
