Study with the aim to see the effect on a space ground analogue , Hyper-Buoyancy Floatation (HBF) on lumbar column and the effect of a supplementary 50% of an axial load.
the aim of this study was to determine the effect of 15min of 1g reloading following 4h HBF unloading with, and without 30s of seated static 50% BW axial loading upon stature, lumbar Intervertebral Disc height (via ultrasound), vertebral compliance changes, and back pain.

Exclusion Criteria:
8 participants (4 males, 25.5±4.4 years, 63.5±10.6 kg, 163.2±5.6 cm)
Device: Hyper-buoyancy Floatation (HBF) · Device: Axial Load after 4h of HBF
8 participants (3 males, 27.0±2.0 years, 68.4±11.8 kg, 176.5±10.9 cm
Device: Hyper-buoyancy Floatation (HBF) · Device: Axial Load after 4h of HBF
Participants remained on a waterbed encased within a wooden frame partially (≈50%) filled with water super-saturated with magnesium sulphate at a temperature between 34-36°C regulated by an ultra-thin underbed heater. Participants remained supine and motionless when lay on the HBF except for temporary passive re-orientation to/and back from the prone position for vertebral compliance assessment
Participants from observational sat upright in a chair without back support for 15 min before post testing (1G), whilst experimental group participants performed a 30s seated squat with 50% of their body weight (BW) before returning to the upright seated position.
