The Study On The Suitable Exercise Training Intensity In The Children And Adolescents With The Non-pathologic-physical Development Retardation

Objective:From February, 2005, the capital research institute of pediatrics expert outpatient clinic " Child Growth and Development Center" against non-pathologic- physical development retardation in children and adolescents begin pilot exercise prescription intervention trial to six months for the cycle and made a good effect. However drawn up after the exercise prescription is not immutable, it is necessary to temper the effects of training are constantly adjusted to strive to exercise prescription and the state remain in the best with subjects. In the intensity of exercise prescription is the most central and most critical factors, the study sought to pre-exercise prescription on the basis of non-pathologic- physical development retardation in children and adolescents, take the heart rate as the main monitor target better instruction seeing a doctor movement exercise, and further confirms its movement intervention effect, based on this explores a relatively accurate movement plan by the time.Study and methods:Selects in February, 2005 to December, 2007 in a Beijing Capital Research institute of pediatrics Expert Outpatient clinic growth center seeing a doctor 5～6 year-old child, the 149 young people to take the acute movement experimental subject, the movement plan refers to this paper 2. 2. 2. 5 growth hormone movement experiment to test the content. Above this research selects a section 7～5 year-old child, the 67young people to take the exercise prescription intervention object. According to sports stage in children and adolescents of different ages (Consolidation age, bone age, the results of The Second Sex levy determine age phase) characteristics of the development. Since the initial out-patient appointments to test different objects, we used the original study and formulate the subjects training exercise prescription for a month (new object) or three months (previously conducted the training here) to review the height, weight and use PolarS410 monitor their movements, such as changes in heart rate after testing main contents include a maximum heart rate, average heart rate, per person after the test results have established training personal files, transfer at any time to check and adjust their exercise prescription. Data analysis using SPSS statistical analysis software for data processing.Results:1. research data show that the movement of the majority of children and adolescents in the maximum heart rate of 193 to 229 bpm, with an average heart rate at between 121 to 130 bpm, exercise prescription to accept the intervention of the maximum heart rate in children and adolescents in the 181 to 204 bpm , the average heart rate is between 112 to 135 bpm, the highest heart rate reached or surpassed the anaerobic threshold intensity, and the average heart rate is close to the corresponding age groups in the lower intensity.2. the campaign from the experiment, sports Intervention Trial men and women of all ages detect changes in heart rate indicators of the outcome of the 10-16-year-old female heart rate slightly higher than the male subjects were 5 to 10 bpm.3. as a short-term acute exercise stress can stimulate significantly increase. The non-pathological-physical development retardation in children and adolescents serum growth hormone levels. In six months of intervention trials, the test object's height, the length, half the growth rate, bone mineral density than intervention appeared before meaningful changes. Especially male volunteers superior to women, that the campaign to promote non-intervention on the pathological growth stunted the growth of children and adolescents is a result of the test object and the need to actively support.Conclusion: 1. The results showed that the most effiecient sports events to non-pathologic-physical development retardation children and adolescents are jumping and running which have mordarate intensity.2. The specific exercise intensity needed according to different age groups stage characteristics of the growth and development of young people, and the physical development of the sensitive period, the exercise load adjusted accordingly. Young men and women of different ages phase of the exercise load different women, 10-16-year-old feminine heart rate slightly higher than the corresponding heart rate 5 to 10 beats/min.
