【摘要】：研究目的:儿童在运动时具有间歇性高强度活动特征,如间歇性跑、跳等。本研究通过对儿童多组6×10m间歇跑全过程的心率与主观疲劳指数的跟踪测试,试图探索儿童在高强度间歇运动后的短时恢复特征。研究方法:选取7~9岁年龄阶段男女儿童各45名作为测试对象。在文献资料调研、专家访谈的基础上,采用测试法,对被试儿童进行3组6×10m间歇跑过程中心率及主观疲劳自评指数进行测量,按年龄进行分组测试及分析。研究结果:1、7~9岁儿童在3组6×10m高强度间歇跑运动中,心率恢复与主观疲劳感受指数均呈现倒“U”特征,在运动后5min内,心率能够较快地恢复到安静状态,主观疲劳感受指数则接近运动前水平。2、7岁儿童中安静心率均值,男童为88.6b/min,女童为87.6b/min。运动后5min心率平均心率男童为86.7b/min,女童为91.8b/min。3组6×10m间歇跑结束后1min的男童心率恢复△HRR均值为48.1 b/min,恢复率为68.5%;女童△HRR均值为60.3 b/min,恢复率为68%。7岁儿童在运动后5min,心率分别恢复至安静心率的100%和95.4%。3、8岁儿童中安静心率均值,男童为84.7b/min,女童为85.7b/min。运动后5min心率平均心率男童为85b/min,女童为85.8b/min。3组6×10m间歇跑结束后1min的男童心率恢复△HRR均值为39 b/min,恢复率为55.4%;女童△HRR均值为38.1b/min,恢复率为57.8%。7岁儿童在运动后5min,心率分别恢复至安静心率的99.6%和99.9%。4、9岁儿童中安静心率均值,男童为84b/min,女童为83.2b/min。运动后5min心率平均心率男童为82.5b/min,女童为83.9b/min。3组6×10m间歇跑结束后1min的男童心率恢复△HRR均值为70.7b/min,恢复率为71.3%;女童△HRR均值为68b/min,恢复率为64.9%。9岁儿童在运动后5min,心率分别恢复至安静心率的100%和99.1%。5、7~9岁儿童能量代谢水平、心脏迷走神经调节能力、疲劳心理认知等是造成高强度间歇运动后心率恢复特征的主要影响因素。研究结论:1、7~9岁儿童在多组高强度间歇运动结束后的1min,心率恢复程度最高,恢复速度最快,运动后3-5min心率恢复速度呈递减特征,运动后5min均能够恢复至安静状态。2、7~9岁儿童在多组高强度间歇运动结束后,心率恢复速度与程度具有性别和年龄特征。总体上,随年龄增长,男童心率恢复程度快于女童。3、7~9岁儿童多组高强度间歇运动过程中,主观疲劳感受指数在性别上无显著性差异。4、7~9岁儿童疲劳心理认知是造成高强度间歇运动后心率恢复特征的主要影响因素。
[Abstract]:Objective: to study the characteristics of intermittent and high-intensity activities in children during exercise, such as intermittent running, jumping, etc. In this study, the heart rate and subjective fatigue index of children during 6 脳 10 m interval running were measured. The purpose of this study was to explore the short-time recovery characteristics of children after high-intensity intermittent exercise. Methods: 45 male and female children aged 7 to 9 years old were selected as test subjects. Based on literature research and expert interviews, the test method was used. Heart rate and subjective fatigue self-assessment index were measured in 3 groups of 6 脳 10 m interval running, and were tested and analyzed in groups according to age. The results showed that children aged 7 years old were in 3 groups of 6 脳 10 m high intensity intermittent running. The recovery of heart rate and subjective fatigue perception index both showed inverted "U" characteristics. In 5min after exercise, the heart rate could recover to quiet state quickly, while the subjective fatigue feeling index was close to the mean of quiet heart rate in children aged 7 years old before exercise. The average heart rate of 5min after exercise was 86.7 b / min for boys, and for boys after 6 脳 10 m interval running in 91.8b/min.3 group, the average recovery of heart rate for boys with 1min was 48.1 b / min, the recovery rate was 68.5; the mean value of HRR for girls was 60.3 b / min, and the recovery rate was 68.7 years old. At 5 min after exercise, the heart rate returned to 100% of that of quiet heart rate and 95. 4% to 95. 4% of the mean of quiet heart rate in 8 years old children. After exercise, the average heart rate of 5min was 85 b / min for boys, 39 b / min for boys with 1min after 6 脳 10 m interval running in 85.8b/min.3 group, and 55.4 for girls, and 38.1 b / min for girls, and 57.8.7 years old for girls. At 5 min after exercise, the heart rate returned to 99.6% of the rest heart rate and 99.9% of the rest heart rate in the children aged 99.9. 4 years old. After exercise, the average heart rate of 5min was 82.5 b / min for boys, 70.7 b / min for boys with 1min after 6 脳 10 m interval running in 83.9b/min.3 group, and 71.3% for girls, and 68 b / min for girls, and 64.9.9 years old children in 83.9b/min.3 group. At 5 min after exercise, the heart rate returned to 100% of that of quiet heart rate and 99.1% to energy metabolism level of 79-year-old children. The ability of regulating cardiac vagus nerve and fatigue psychological cognition were the main influencing factors of heart rate recovery after high intensity intermittent exercise. Conclusion the recovery degree of heart rate in 79-year-old children was the highest at 1 min after the end of high intensity intermittent exercise. The recovery rate of 3-5min was the fastest and the heart rate of 3-5min decreased after exercise. After exercise, 5min was able to recover to a quiet state. All the children aged 7 years old were able to recover after several groups of high intensity intermittent exercise. The rate and degree of heart rate recovery were of gender and age characteristics. In general, the recovery rate of heart rate in boys was faster than that in girls. There was no significant gender difference in subjective fatigue perception index. The psychological cognition of fatigue in children aged 7 years old was the main influencing factor of heart rate recovery after high intensity intermittent exercise.
