Effect of a pulsating anti-gravity suit on peak exercise performance in individual with spinal cord injuries

European Journal of Applied Physiology, 1999
The aim of this study was to examine effects of a pulsating pressure anti-gravity suit on the peak values of oxygen uptake (VO2) and power during maximal arm exercise in spinal-cord-injured (SCI) individuals. Five well-trained SCI men (with lesions at levels between T6 and L1) and seven well-trained able-bodied men (ABC) performed two incremental (10 W

Gravity and magnetic signatures of the Ackley Granite Suite, southeastern Newfoundland: implications for magma emplacement

Canadian Journal of Earth Sciences, 1989
A detailed gravity survey (255 stations over an area of 3000 km2) over the posttectonic, Devonian, Ackley Granite Suite in southeastern Newfoundland suggests that a set of northwest-trending geophysical lineations, interpreted as faults, controlled the bottom morphology of the magma chamber during emplacement.The main negative Bouguer gravity anomaly ...

The use of artificial muscles in space suit simulation for partial gravity experimentation and training

2011 Aerospace Conference, 2011
The Aurora/MIT project team has developed a knee joint prototype for a space suit simulator that is designed to be lower weight and form-factor than previous simulators, while mimicking the resistive properties to human motion that pressurized space suits necessarily impose.

Design of Passive Gravity Balance Mechanism for Wearable Exoskeleton Suit

2019
The wearable exoskeleton suit is a man-machine system which can combine the human limbs with machinery and environment. The key point of wearable exoskeleton suit is the design of passive gravity balance mechanism to achieve passive gravity balance in the system.

A Pulsating Anti-Gravity Suit for Acceleration Protection: System Description and Preliminary Experiments

1986
Abstract : This document describes a system designed to study the feasibility of augmenting tolerance to acceleration stress using external pressure pulsations synchronized to the electrocardiogram. The system, known as synchronized pulsating anti-gravity suit, consists of a modified G Suit, a controller and a pneumatic subsystem. The modified suit has

An experimental microcomputer controlled system for synchronized pulsating anti-gravity suit.

Aviation, space, and environmental medicine, 1987
An experimental system to deliver synchronized external pressure pulsations to the lower body is described in this technical note. The system is designed using a microcomputer with a real time interface and an electro-pneumatic subsystem capable of delivering pressure pulses to a modified anti-G suit at a fast rate.

[Adaptation of humans to walking in semi-hard and flexible space suits under terrestrial gravity].

Aviakosmicheskaia i ekologicheskaia meditsina = Aerospace and environmental medicine, 2011
The spacesuit donning-on procedure can be viewed as the combining of two kinematic circuits into a single human-spacesuit functional system (HSS) for implementation of extravehicular operations. Optimal human-spacesuit interaction hinges on controllability and coordination of HSS mobile components, and also spacesuit slaving to the central nervous ...

The gravity suit: a major advance in management of gynecologic blood loss.

Obstetrics and gynecology, 1979
We have used the gravity suit (G-suit) to stabilize patients in shock as a result of ruptured ectopic pregnancies. Four patients presenting in shock were carefully studied with serial vital signs, fluid replacement, and blood loss before and after application of the G-suit. These studies were continued through surgery and the removal of the G-suit. The

Renin stimulation by passive tilting: The influence of an anti-gravity suit on postural changes in plasma renin activity, plasma noradrenaline concentration and kidney function in normal man

Scandinavian Journal of Clinical and Laboratory Investigation, 1978
Plasma renin activity (PRA), plasma noradrenaline concentration, heart rate, blood pressure, and clearances of para-aminohippurate and inulin were measured in twelve normal subjects (clearances in only three subjects) before and after 40 min of 60 degrees upright tilting.

Postural hypotension and the anti-gravity suit.

Australian family physician, 1995
An air force anti-gravity suit, as used by fighter pilots to prevent loss of consciousness, has been successfully employed to treat severe postural hypotension in a patient with Shy-Drager syndrome. The definition of postural hypotension is reviewed, and reference is made to the previous use of the anti-gravity suit in the treatment of this condition.
