在四名受110天禁闭的男子中检查了阻力运动范例的功效，该范例使用了与重力无关的飞轮原理（空间站上国际机组人员飞行模拟; SFINCSS-99）。受试者在禁闭期间每周进行2-3次上半身和下半身锻炼（小腿抬高、下蹲、背部伸展、坐行、侧肩抬高、二头肌卷曲）。运动方案包括四组，每组10次重复，估计最大努力的80-100%。在每次运动中测量和记录工作。最大自愿等长力量在小腿按压，蹲下和背部伸展，进行了评估，在三个不同的关节角度之前和之后的限制。总体而言，在干预过程中，所有受试者的训练负荷（工作）都增加了（范围为16-108%）。最大自愿等长力量是不变的限制。虽然应变和舒适度的感知水平不同的演习和个人之间，本研究的结果表明，这种阻力运动方案是有效的，在长期禁闭期间保持甚至增加性能和最大的力量输出。在设计拟在国际空间站上使用的阻力锻炼硬件和处方时，应考虑到这些发现。
The efficacy of a resistance exercise paradigm, using a gravity-independent flywheel principle, was examined in four men subjected to 110 days of confinement (simulation of flight of international crew on space station; SFINCSS-99). Subjects performed six upper- and lower-body exercises (calf raise, squat, back extension, seated row, lateral shoulder raise, biceps curl) 2-3 times weekly during the confinement. The exercise regimen consisted of four sets of ten repetitions of each exercise at estimated 80-100% of maximal effort. Work was measured and recorded in each exercise session. Maximal voluntary isometric force in the calf press, squat and back extension, was assessed at three different joint angles before and after confinement. Overall, the training load (work) increased in all subjects (range 16-108%) over the course of the intervention. Maximal voluntary isometric force was unchanged following confinement. Although the perceived level of strain and comfort varied between exercises and among individuals, the results of the present study suggest this resistance exercise regimen is effective in maintaining or even increasing performance and maximal force output during long-term confinement. These findings should be considered in the design of resistance exercise hardware and prescriptions to be employed on the International Space Station.
