Improvement of Physical Fitness Test Assessment Criteria Based on fNIRS Technology:Taking Pull-Up as an Example

摘要

Pull-up,as an important physical fitness test event of the“National Student Physical Health Standard”,is known as a difficult physical fitness test event.To improve the assessment criteria of pull-ups,this paper uses the functional near-infrared spectroscopy(fNIRS)to monitor the changes and activation of oxyhemoglobin(HbO)signals in the brain motor cortex of people with different body mass indexes(BMIs)during the pullup assessment.Then the relationship between BMIs and evaluation criteria is discussed.After collecting and analyzing experimental data of 18 recruited college students,it is found that the number of pull-ups performed by people with different BMIs is different when they reach the peak state of brain activation.The results of the study indicate that different assessment criteria should be adopted for different BMI groups.It is suggested that the BMI should be introduced as one of the test indexes in the examination of pull-ups event in“National Student Physical Health Standard”.
