The effect of flexible body armour on pulmonary function

Ergonomics, 2015
The additional mass and fit of current military in-service body armour (ISBA) can reduce pulmonary function in a way that is characteristic of a restrictive respiratory impairment. This could ultimately impair exercise capacity and military performance.

V50 Determination Challenges for State-Of-The-Art Body Armour

16th Personal Armour Systems Symposium (PASS 2023), 2023
The material constructions in personal protective equipment (PPE) have shifted over the last decades. In soft armour ballistics the construction shifted from plain wave fabrics towards more use of Unidirectional (UD) sheets. Also, the use of Ultra High Molecular Weight Polyethylene (UHMWPE) fabric constructions increased significantly compared to ...

Influence of body armour on pulmonary function

Ergonomics, 1988
The purpose of the present study was to determine if lightweight body armour (weighing less than 10 kg) would influence pulmonary function in a manner similar to that reported previously for backpacks and heavily weighted jackets. In three separate experiments involving a total of 30 healthy young males wearing three types of body armour, there was a ...

The destabilizing effect of body armour on military rifle bullets

International Journal of Legal Medicine, 1997
Soft body armour is designed to give protection against fragments and some low velocity bullets but is not designed to stop high velocity rifle bullets. Reports have claimed that soft body armour might disturb the stability of bullets that penetrate it, and that this might increase the size of the lesions.

Effects of police body armour on overmatching ballistic injury

International Journal of Legal Medicine, 2019
Overmatching occurs when body armour that has been designed to resist perforation by a specified projectile is perforated by a greater threat. This may result in wounding to the body armour wearer. In this work, overmatching of two types of police body armour was studied using two types of ammunition.

Comfort properties of 3D-knitted seamless female body armour vests

Journal of the Textile Institute, 2017
This paper reports the comfort properties of 3D-knitted seamless female body armour vests evaluated by using a thermal manikin. The vests were designed as a complete garment with eliminating the conventional cutting and sewing, to improve fit and comfort

Genetics of body shape and armour variation in threespine sticklebacks.

Journal of evolutionary biology, 2011
Patterns of genetic variation and covariation can influence the rate and direction of phenotypic evolution. We explored the possibility that the parallel morphological evolution seen in threespine stickleback (Gasterosteus aculeatus) populations colonizing freshwater environments is facilitated by patterns of genetic variation and covariation in the ...

An analytical model for ballistic impact on textile based body armour

Composites Part B: Engineering, 2013
Polymer fibres with high tenacity and modulus such as Kevlar® are widely used in personal protection applications. Normally these fibres are manufactured into different fabric structures before being assembled layer by layer to form personal protection panels.

Body armour: the effect of load, exercise and distraction on landing forces

Journal of Sports Sciences, 2013
We investigated the effect of added load and intense exercise on jump and landing performance and ground reaction force (GRF) during landings where attentional demand was varied. Fifty-two males (37 ± 9.2 years, 180.7 ± 6.1 cm, 90.2 ± 11.6 kg, maximal aerobic fitness (VO(₂max)) 50 ± 8.5 ml (.) kg(-1 .) min(-1), BMI 27.6 ± 3.1, mean ± s) completed a VO ...

Personal protective body armour

1989
Benefit (protection) and drawbacks (functional obstruction, physiological impairment) of body armour are discussed. The mechanism of physiological impairment seems to be rather straightforward and can be explained by an impairment of heat exchange. However, protection and functional obstruction are still subject to dispute, mainly where the conversion ...
