项目摘要

The purpose of the present research is to develop of the exercise prescription programs to be paid attention of risks of over training and overuse in younger students during developmental stages. The research mainly consists of two different experiments: human experiments (respiratory and circulation research in response to exercise and training) and animal experiments (adaptive responses of bone and skeletal muscle in response to exercise, training, and detraining).The research results are summarized as follows:1. The exercise training (rowing exercise) increases the left ventricular diastolic dimension and left ventricular mass index without impairment of left ventricular diastrolic function in college female students.2. The arterial conductance vessels can be morphologically altered in an adaptive response Io the endurance training. Furthermore, the dilation of the conductance vessels with endurance training contributes to an increases in blood flow to the exercising muscles without a rise in blood velocity.3. Motor control mechanisms to account for these sudden and frequent changes in the combinations of motor units and motor pools that will contribute to a prolonged low- level force effort remain unknown.4. The etidronate treatment for 2 weeks beforehand influenced the effects of subsequent exercise training on maintaining the bone mineral density in the proximal femur and trabecular bone area of the tibia.5. The differential growth of muscle fibers in response to exercise leads to the formation of abnormal membrane systems involved in the excitation-contraction coupling with very unique morphological features.6. The voluntary loaded running exercise is more effective for muscle enlargement than treadmill running training and/or voluntary running training with no load in rat skeletal muscle.All of these results are thought to be significant and important data to develop a exercise prescription.

本研究的目的是发展运动处方计划，以关注低年级学生在发展阶段的过度训练和过度使用的风险。研究主要包括两个不同的实验：人体实验（运动和训练后的呼吸和循环研究）和动物实验（骨骼和骨骼肌对运动、训练和去训练后的适应性反应）。研究结果总结如下：1。运动训练（划船运动）增加了女大学生左室舒张度和左室质量指数，但不损害左室舒张功能。在耐力训练的适应性反应中，动脉传导血管可以发生形态学改变。此外，耐力训练时传导血管的扩张有助于增加运动肌肉的血流量，而不会增加血液流速。运动控制机制，以解释这些突然和频繁的变化，在运动单元和运动池的组合，将有助于长期低水平的力量努力仍然是未知的。4 .提前2周给予依地膦酸钠治疗影响后续运动训练对维持股骨近端和胫骨小梁区骨矿物质密度的影响。肌肉纤维对运动的不同生长反应导致异常膜系统的形成，涉及兴奋-收缩耦合，具有非常独特的形态特征。在大鼠骨骼肌中，自愿负重跑步运动比跑步机跑步训练和/或无负荷自愿跑步训练对肌肉扩张更有效。所有这些结果都被认为是制定运动处方的重要数据。
