摘　　要：目的:拟评定中等强度和高强度两种运动强度下长距离负重行军对健康男性青年执行功能产生的影响。方法:受试人员完成两次长度为18.5 km的负重行军,持续监控整个运动过程中心率变化,询问主观量表,并分别采用斯特鲁普色词测试(Stroop-Word-Color Test,SWCT)和连线测试(Trail Making Test,TMT)对受试者执行功能进行测试。结果:SWCT结果显示,与安静状态相比较,中等强度运动后抑制控制能力存在显著变化(p<0.05),高强度运动后抑制控制能力也存在显著变化(p<0.05),但中等强度运动和高强度运动后抑制控制能力方面并没有显著性差异(p>0.05)。TMT结果显示,在注意选择能力方面,中等强度运动后结果与安静状态相比存在显著变化(p<0.05);高强度运动后结果与安静状态相比较无显著变化(p>0.05);但是中等强度与高强度运动后结果存在显著性差异(p<0.05)。结论:大强度负重行军后注意力控制能力仍能够较好维持,注意选择功能受到影响。Objective: This study was to evaluate the effect of long-distance weight march on the executive function of healthy male youth under moderate and high intensity. Method: The individual needs to complete twice the total length of 18. 5 km weight march,continuous monitoring of the entire process of heart rate changes. Asking the subjective feeling and using the Stroop-Word-Color Test and the Trail Making Test to evaluate the executive function before and after the whole process. Result: The results of SWCT showed that there was significant change in the inhibition control function after moderate-intensity exercise(p < 0. 05),there was also significant change after high-intensity exercise(p < 0. 05),but there was no significant difference between moderate-intensity exercise and high-intensity exercise in inhibition control function(p > 0. 05). The results of TMT showed that there was no significant change in the results of moderate intensity after exercise(p < 0. 05). However,there was no significant change in the results after high intensity exercise(p > 0. 05),there was a significant difference between the moderate-intensity and the high-intensity exercise(p < 0. 05). Conclusion: Attention control ability in the large strength after the march can still be better maintained,but selection and attention functions are affected.
