Endurance training was conducted on a group of 41 East Indian boys aged 10-14 years and was compared with 25 untrained boys of the same age. A continuous slow-running method was adopted for 12 weeks. The intensity of the training was 80-85% of maximum heart rate and frequency was 3 days per week. The boys were trained for a 1500-m event and therefore they covered three to five times their racing distance. For psychological reasons the training was carried out in a playground. The investigations included different physical and motor fitness tests: measurement of flexibility, agility, speed, leg muscle strength etc. Their performance times were also recorded before and after training. From statistical analysis we concluded that this particular type of training programme did not produce any detrimental effects on 10-14-year-old boys. On the other hand, this type of training did have some influence on improving physiological parameters in this age group of boys when compared with untrained boys of the same age.
对一组41名年龄在10至14岁的东印度男孩进行了耐力训练，并与25名同龄未受过训练的男孩进行了比较。采用持续慢跑的方法，为期12周。训练强度为最大心率的80 - 85%，频率为每周3天。这些男孩针对1500米项目进行训练，因此他们跑的距离是比赛距离的三到五倍。出于心理原因，训练在操场进行。调查包括不同的身体和运动能力测试：柔韧性、敏捷性、速度、腿部肌肉力量等的测量。还记录了他们训练前后的成绩时间。通过统计分析，我们得出结论，这种特定类型的训练计划对10至14岁的男孩没有产生任何有害影响。另一方面，与同龄未受过训练的男孩相比，这种训练对改善该年龄组男孩的生理参数确实有一定影响。
