GROWTH HORMONE VARIANTS, PULSATILITY & RESISTANT EXERCISE

本研究的目的是确定抗阻训练对生长激素（GH）浓度、GH分泌的脉冲特性和GH对靶组织的作用的影响。将在16小时内进行连续血液采样，以测量正常条件下和大容量大阻力运动下的生长激素浓度。据推测，由于生长激素脉冲的宽度和幅度的增加，生长激素会随着运动剂量的增加而增加。生长激素的免疫反应性预计显示出运动剂量关系，其中最大的反应预计在低分子量范围内。预计肌管的增殖与运动剂量有一定的关系。

The aim of this study is to determine the impact of resistance training on growth hormone (GH) concentrations, pulse characteristics of GH secretion and GH actions on target tissue. Serial blood sampling over 16 hours will be performed to measure GH concentrations under normal conditions and high volume heavy resistance exercise. It is hypothesized that GH will increase in response to the exercise dose, due to an increase in width and amplitude of GH pulses. GH immunoreactivity is expected to show an exercise -dose relationship where the greatest response is expected in the lower molecular weight range. It is also expected that there is an exercise-dose relationship on the proliferation of myotubes.
