The Influence Of Recovery Time After Exercise On College Students’Cognitive Control

Objective:The relationship between exercise and cognition has become a hot topic of globalconcern. With the deepening of related research, people are able to more clearlyunderstand and recognize it now. In this paper, the environmental conditions in thelaboratory, using near-infrared spectroscopy of brain science and technology, recoverywas observed before and after the test organism load stimulated by the movement of theload and the corresponding time in the form of executive control aspects of brainactivation status, and related indicators NIRS change, hoping to explore a number of lawsthat exist between the recovery time after exercise and cognitive control abilities, andexplore the exercise load and recovery time for the impact of cognitive control.Methods:In this paper, using near-infrared spectroscopy (NIRS), the study selected non-sportsCapital University of Physical Education and Sports18. Consent and signed the informedconsent of the subjects consent after20minutes once the low load target heart ratecontrolled by treadmill exercise, and before the load (pretest), and intermittent load end10minutes (measured), the end of the load and Intermittent30minutes (post-test) tocomplete a total of three testing phases flanker task. By near infrared spectroscopyinstrument to collect oxygen index of the brain. In the experiment in progress, the keypoints to be collected physiological indicators recorded heart rate, blood lactate, RPE andblood oxygen saturation. Before the start of the experiment and after the end of thesubjects to fill Watson Mood Scale.The results:1Comparison of the test results found Flanker task, the task of consistencyconditions, the pretest and post-test than the pretest improve the accuracy and reduce thereaction; the inconsistent condition task, measured in the pretest and post-test than thecorrect rate, decrease when compared to the previous test measured response, nosignificant difference in the post-test than pretest response. Women and men test showedno significant difference.2Watson test: at the end of the experiment subjects, negative mood scores comparedto the previous experimental class began to decline or remain unchanged, suggesting thatnegative emotions eased, most active class sentiment scores rise, indicating that positive sentiment has improved. Willed and carefully scores drop, considering the resultingdecrease in energy.3Physiological in dices, heart rate and blood lactate relatively high degree ofcorrelation, showing a significant correlation level (P <0.05); RPE and heart rate have ahigh degree of correlation, correlation level is very significant (P <0.01).Conclusions:1After the test results on a flanker, combined with physiological indicators showedthat short-term low-intensity aerobic exercise on the implementation of the controlfunction of ordinary college students promoted.2After two pairs Watson subjective indicators of mood change analysis found thatthere is a significant change from the previous experiment after experiment, indicating thatlow-intensity aerobic exercise on mood states can promote ordinary college students.3Short-term low-intensity aerobic exercise and rest, the former relative variation ofthe brain than the movement of oxyhemo glob in have improved significantly increasedportion of the channel; after a longer break, the relative change in the amount ofhemoglobin oxygenation still improves movement than before, description of lowintensity aerobic exercise for the brain to produce effective stimulation.4Between blood lactate, heart rate and RPE and other indicators of significantcorrelation between them to determine the movement of fatigue is very significant andobjectivity.
