Objective

The purpose of this study was to examine the influence of a novel “floatation-restricted environmental stimulation therapy” (floatation-REST) on growth hormone responses to an intense resistance exercise stress.

Design

Nine resistance trained men (age: 23.4 ± 2.5 yrs.; height: 175.3 ± 5.4 cm; body mass: 85.3 ± 7.9 kg) completed a balanced, crossover-controlled study design with two identical exercise trials, differing only in post-exercise recovery intervention (i.e., control or floatation-REST). A two-week washout period was used between experimental conditions. Plasma lactate was measured pre-exercise, immediately post-exercise and after the 1 h. recovery interventions. Plasma iGH was measured pre-exercise, immediately-post exercise, and after the recovery intervention, as well as 24 h and 48 h after the exercise test. The bGH-L was measured only at pre-exercise and following each recovery intervention.

Results

For both experimental conditions, a significant (P ≤ 0.05) increase in lactate concentrations were observed immediately post-exercise (~14 mmol • L-1) and remained slightly elevated after the recovery condition. The same pattern of responses was observed for iGH with no differences from resting values at 24 and 48 h of recovery. The bGH-L showed no exercise-induced changes following recovery with either treatment condition, however concentration values were dramatically lower than ever reported.

Conclusion

The use of floatation-REST therapy immediately following intense resistance exercise does not appear to influence anterior pituitary function in highly resistance trained men. However, the lower values of bGH suggest dramatically different molecular processing mechanisms at work in this highly trained population.

使用“漂浮”从高强度压力中恢复抗阻力训练的男性生长激素样分子

客观的

这项研究的目的是检查一种新型的“漂浮限制环境刺激疗法”（漂浮-REST）对生长激素对强烈抵抗运动压力的反应的影响。

设计

九名受过阻力训练的男性（年龄：23​​.4 ± 2.5 岁；身高：175.3 ± 5.4 厘米；体重：85.3 ± 7.9 公斤）完成了一项平衡、交叉对照的研究设计，其中包括两项相同的运动试验，仅在运动后恢复方面有所不同干预（即控制或浮动-REST）。在实验条件之间使用了两周的清除期。在运动前、运动后立即和 1 小时后测量血浆乳酸。恢复干预。在运动前、运动后立即、恢复干预后以及运动试验后 24 小时和 48 小时测量血浆 iGH。bGH-L 仅在运动前和每次恢复干预后测量。

结果

对于这两种实验条件， 在运动后立即观察到乳酸浓度显着增加（P ≤ 0.05）（~14 mmol • L-1），并在恢复条件后保持轻微升高。对 iGH 观察到相同的反应模式，与恢复 24 和 48 小时的静息值没有差异。在两种治疗条件下恢复后，bGH-L 均未显示运动引起的变化，但浓度值比以往报告的要低得多。

结论

在高强度阻力训练后立即使用漂浮-休息疗法似乎不会影响受过高度阻力训练的男性的垂体前叶功能。然而，bGH 的较低值表明在这个训练有素的人群中起作用的分子加工机制截然不同。
