摘要
意志力是一个人自觉地确定目标，并根据目的来支配，调节自己的行动，克服各种困难，从而实现目的的个性心理品质。意志力可以让人有深刻的目的，在困难面前不退缩；在复杂的情境中冷静而迅速的判断发生的情况，采取坚决的措施和行动，果断的处理事情；碰到挫折和失败时，调节自己的情绪，控制自己的行为；用百折不挠的毅力，战胜挫折和困难，实现自己设定的目标。根据近几年有关研究结果可以看出，现在的中学生的意志力水平普遍显现下降的趋势，依赖性强、缺乏克服困难的信心、进取心降低等现象突出。
由于中长跑运动项目除需要有良好的耐力素质外还需要有强大的意志力才能取得好的运动成绩。但现实中我国初中学生800米/1000米中考的总体成绩在目前为止处于一种下降的态势，因此，提高初中学生耐力素质与增强他们的意志力是现代初中体育工作急需解决的一个问题。为此，本论文试通过对初中学生进行不同强度的耐力素质训练来验证提高初中学生意志力的有效方法，为提高初中素质教育水平提供参考。
本实验研究将耐力训练的强度依心率来划分为五个等级，对应的实验组为130次/min、140次/min、150次/min、160次/min、170次/min。通过以上5种强度的耐力跑训练来提高中学生的耐力素质和意志力水平，并通过学生意志力量表的前后测试来验证不同强度的耐力素质训练对学生意志力的影响。
本文运用了文献资料法、调查法、实验教学等方法，设计并实验了五种不同强度的耐力素质训练，最后采用数理统计法对数据进行整理、分析，得出如下研究结果：通过相关分析，高强度与低强度的耐力素质的p值大于0.05，高强度与低强度的耐力素质训练对学生的意志力没有显著差异，低强度和高强度的耐力素质对学生意志力的提高不显著，由于过高或者过低强度训练，学生在训练过程中容易产生逆反心理或消极怠慢的情绪，所以高强度和低强度的耐力素质训练对学生的意志力没有显著影响。较低强度、中强度、较高强度的p值小于0.05，对学生的意志力有显著差异，再通过对较低强度后测意志力、中强度后测意志力，较高强度后测意志力进行相关统计分析，实验结果为方差齐性，p<0.05，三种强度两两之间互有显著差异，检验结果为中强度的耐力素质训练对学生的意志力提高最有效，中强度的耐力素质训练是提高学生意志力的最合适强度。
结论：
1.低强度组学生的心率要达到130次/min，训练后对学生的意志力没有显著差异，学生意志力没有提高的原因是运动强度较小，困难太低，学生可以轻而易举的完成训练，低强度的耐力素质训练对学生的刺激不够，学生没有出现到达极点的生理反应，在训练过程中学生也没有因为过度疲劳出现中途退出的情况，所以低强度训练对学生意志力的提高效果不显著。
2.较低强度组学生在训练中，学生的心率要达到140次/min，对学生的意志力有显著差异，有一个学生

的意志力出现下降状态，较低强度的耐力素质训练强度会比低强度耐力素质训练的强度大，对学生有所刺激，但是通过分析，对学生的刺激相对较小且有学生出现下降状态，不是提高学生意志力的最适宜强度。
3.中强度组学生在训练中，学生的心率要达到150次/min，对学生的意志力有显著影响，且没有学生出现意志力下降情况，中强度耐力素质训练强度要比较低强度组大，在训练中可以让学生感受到训练带给身体的不适，并可以接受这个强度，依靠自己的意志力继续完成训练，是提高学生意志力的最合适强度。
4.较高强度组学生的心率要达到160次/min，经过较高强度的耐力素质训练后，对学生的意志力有显著差异，但多个学生的意志力出现下降情况，较高强度耐力素质训练的强度较大，学生难以克服，易导致学生丧失自信，致使学生的训练动机降低，多个学生的意志力得分下降。较高强度耐力素质训练不是提高学生的最适宜强度。
5.高强度组学生的心率要达到170次/min，对学生的意志力没有显著差异，高强度组的训练强度在五个组里面最大，学生在高强度的训练下感到疲劳，并且难以坚持下去，削减学生训练的积极性，并造成学生逆反心理的情况发生，对学生的意志力提高不明显，所以高强度的耐力素质训练不是提高学生意志力的最合适强度。

Abstract
Willpower is the personality psychological quality that a person consciously determines the goal and dominates according to the goal,adjusts his own action,overcomes all kinds of difficulties,and thus realizes the goal.Willpower can give people a profound purpo,do not retreat in the face of difficulties;in complex situations calm and rapid judgment of what happened,take firm measures and actions,decisively deal with things;in the face of tbacks and failures,adjust their emotions,control their own behavior;with perverance,overcome tbacks and difficulties,achieve their t goals.According to the rearch results in recent years,it can be en that the willpower level of middle school students is generally apparent The trend of decline,strong dependence,lack of confidence to overcome difficulties,less enterprising phenomenon prominent.
Becau middle distance running sports not only need to have good endurance quality but also need
strong willpower to achieve good sports performance.But in reality,the overall achievement of800m/1000m middle school students in our country is in a declining situation at prent.Therefore,improving the endurance quality of junior middle school students and enhancing their willpower are an urgent problem to be solved in modern junior middle school physical education work.To this end,this paper tries to verify the effective method of improving the willpower of junior middle school students by carrying out different strength endurance quality training for junior middle school students,so as to provide reference for improving the quality education level of junior middle school students.
This study divided the strength of endurance training into five grades according to the heart rate,corresponding to the experimental group of130/min、140/min、150/min、160/ min、170/min..Through the above5kinds of strength endurance running training to improve the endurance quality and willpower level of middle school students,and through the test before and after the test of students'will strength table to verify which strength endurance quality training is more effective for the improvement of students'willpower.
In this paper,five kinds of endurance quality training with different intensity are designed and tested by means of literature method,investigation method and experimental teaching method.Finally,the da
softimage
ta are sorted and analyzed by mathematical statistics method, and the following rearch results are obtained:
By correlation analysis,the p value of high intensity and low intensity endurance quality is greater than0.05,there is no significant difference between high intensity and low intensity endurance quality training on students'willpower,and the improvement of students' willpower is not significant.p values of lower intensity,medium intensity and higher intensity are less than0.05,which has significant difference to students'willpower,and then measured the willpower after lower intensity The results showed that there were significant differences between the three types of strength p<0.05.The results showed that the medium strength endurance quality training was the most effective to improve the students' willpower.The medium strength endurance quality training was the most suitable strength to improve the students'willpower.
Conclusion:

1.There is no significant difference in students'willpower after130beats/min,training in1.low-intensity group.The reason why students'willpower did not improve is that the
exerci intensity is small,the difficulty is too low,students can easily complete the training.
2.the lower intensity group students'heart rate to140beats/min,had a significant difference in students'willpower,one student's willpower decread,the lower intensity of endurance quality training intensity will be greater than the lower intensity of endurance quality training intensity,some students are stimulated,but through analysis,the stimulation of students is relatively small and students appear to decline state,is not the most appropriate intensity to improve students'willpower.
3.strength group students'heart rate of150beats/min,has a significant effect on students'willpower,and no students'willpower decline.The strength of medium strength endurance quality training is higher than that of low intensity group.
4.the heart rate of the students in the higher intensity group reached160beats/min, after the higher intensity endurance quality training,there were significant differences in the students'willpower,but the willpower of many students decread,the intensity of the higher intensity endurance quality training was higher,the students were difficult to overcome, which easily led to the loss of lf-confidence,resulting in the students'training motivation decread,and the scores of the students'willpower decread.Low strength endurance quality training is not the most suitable strength to improve students.

5.the heart rate of the students in the high intensity group was170beats/min,,there was no significant difference in the students'willpower.The training intensity of the high intensity group was the largest in the five groups.

6.high intensity and low intensity training have no significant effect on students' willpower,lower intensity endurance quality,medium intensity endurance quality training, and high intensity endurance quality training have a significant effect on students'willpower. through analysis,medium intensity is the most suitable intensity to improve students' willpower.
