50% body weight loading reduces stature increases and lumbar disc expansion from 4 h hyper‐buoyancy floatation versus 15 min sitting upright

open access: yesExperimental Physiology, EarlyView.
Abstract Microgravity is associated with stature increases, back pain and post‐flight intervertebral disc (IVD) herniation. This study aims to determine whether 30 s seated 50% body weight (BW) axial loading is comparable to 15 min sitting upright in 1 g upon changes in stature, anterior lumbar IVD height (via ultrasound), passive vertebral stiffness ...

Integrative cardiovascular dose–response to graded lower‐body negative pressure

open access: yesExperimental Physiology, EarlyView.
ABSTRACT Lower‐body negative pressure (LBNP) has been posited as a potential spaceflight countermeasure to counteract the physiological deconditioning related to fluid shifts in microgravity. However, open questions remain regarding the magnitude of LBNP that should be applied.

Cardiac conduction system and the electrocardiogram of the common hippopotamus (Hippopotamus amphibius)

open access: yesExperimental Physiology, EarlyView.
Abstract The common hippopotamus (Hippopotamus amphibius) shares a common terrestrial ancestor with whales (Cetacea) and has independently evolved similar physiological adaptations to their aquatic lifestyle. Although several studies have explored the electrical signalling in whale hearts, the understanding of the conduction system and electrical ...
