Me permito hacer uso de mi "membresía" para abrir un nuevo hilo sobre Medicina Aeroespacial, busqué dentro de los sub hilos y no hallé algo parecido así que si se me chispoteó no hay problema, los administradores pueden tomar cartas en el asunto.
Podríamos colgar info relacionada, estamos para aprender. Yo mismo quisiera seguirme desasnando en este rubro y ver al ser humano como un TODO y que pese al avance de la tecnología el gran limitante HOY es el mismo cuerpo humano. No por nada algunos analistas proclaman que el futuro avión de 6ta GEN será no tripulado.
Saludos y les dejo con un abstract sobre actividad muscular del cuello en pilotos de combate que usan dispositivos integrados en casco de visión nocturna. Ojo! los del JAS-39.

Hay que entrenar el cuello para soportar tal carga de estrés encima. Existirá un programa para ello? seguro que si pero, cual?

Abstract:
Äng BO, Kristoffersson M. Neck muscle activity in fighter pilots wearing night-vision equipment during simulated flight. Aviat Space Environ Med 2013; 84:125-33.
Introduction: Night-vision goggles (NVG) in jet fighter aircraft appear to increase the risk of neck strain due to increased neck loading. The present aim was, therefore, to evaluate the effect on neck-muscle activity and subjective ratings of head-worn night-vision (NV) equipment in controlled simulated flights. Methods: Five experienced fighter pilots twice flew a standardized 2.5-h program in a dynamic flight simulator; one session with NVG and one with standard helmet mockup (control session). Each session commenced with a 1-h simulation at 1 Gz followed by a 1.5-h dynamic flight with repeated Gz profiles varying between 3 and 7 Gz and including aerial combat maneuvers (ACM) at 3-5 Gz. Large head-and-neck movements under high G conditions were avoided. Surface electromyographic (EMG) data was simultaneously measured bilaterally from anterior neck, upper and lower posterior neck, and upper shoulder muscles. EMG activity was normalized as the percentage of pretest maximal voluntary contraction (%MVC). Head-worn equipment (helmet comfort, balance, neck mobility, and discomfort) was rated subjectively immediately after flight. Results: A trend emerged toward greater overall neck muscle activity in NV flight during sustained ACM episodes (10% vs. 8% MVC for the control session), but with no such effects for temporary 3-7 Gz profiles. Postflight ratings for NV sessions emerged as “unsatisfactory“ for helmet comfort/neck discomfort. However, this was not significant compared to the control session. Conclusions: Helmet mounted NV equipment caused greater neck muscle activity during sustained combat maneuvers, indicating increased muscle strain due to increased neck loading. In addition, postflight ratings indicated neck discomfort after NV sessions, although not clearly increased compared to flying with standard helmet mockup.

. Vale la pena darle una leidita.
