Update on Nutritionally Optimized First Strike Ration(NOFSR) Army Technology Objective (ATO) D.SO.2005.02October 2008


Background purpose

Background & Purpose

  • Background:

    • The FSR™ is a compact, eat-on-the-move ration designed to be consumed during short-term high-intensity missions

    • The FSR™ substantially reduces the size and weight burden to the Warfighter with features designed to enhance consumption, nutritional intake, and mobility

    • Components of the FSR™ include food items that are lightweight, easy to consume, and require little or no preparation

    • Snacking and caffeine have individually been shown to improve physical and cognitive performance

  • Purpose:

    • To determine if NOFSR better sustained ability to make correct decisions (cognitive performance) and perform physical work during repeated days of physically-demanding, near-continuous military field operations

Experimental design

Experimental Design

  • Subjects: n= 50 Marines (46 men, 4 women)

  • 4-day dismounted FTX

  • ½ platoon provided FSR™ (n=26); ½ platoon provided MRE™ (n = 24)

  • Food consumption calculated from food logs and food waste

  • Activity measured by wrist-worn actigraph

  • Reaction time, logical reasoning ability, and mood measured with PDA-based tests on day 1, 3, 4 and 5 of FTX

Summary nofsr ato 1 st study

Summary NOFSR ATO 1st Study

  • Data supports greater food consumption with FSR™ compared to MRE™

  • There are trends supporting that FSR™ items better sustains mood and alertness compared to MRE™ however, additional testing will be needed to confirm these observations

  • Additional study(s) to be conducted:

    • To increase “n” performed in May to quantify trends

    • To further test the effect of NOFSR on physical performance

    • Target Marine Corps Basic Officer Training School for first study and unit TBD for second (if it occurs)


Experimental design 2 nd study

Experimental Design (2nd Study)

  • Subjects: n= 39 Marines (36 men, 3 women)

  • 4-day dismounted FTX

  • ½ platoon provided FSR™ (n=20); ½ platoon provided MRE™ (n = 19)

  • Food consumption calculated from food logs and food waste

  • Activity measured by wrist-worn actigraph

  • Reaction time, logical reasoning ability, and mood measured with PDA-based tests on day 1, 2, 3, 4 and 5 of FTX

  • PDA based cognitive testing was performed

  • Implications of not eating enough was discussed during the last day


Summary

Summary

  • Both NOFSR field tests were conducted at Quantico, VA during the Marine Corps Basic Officer Training School

  • Data still supports greater food consumption with FSR™ compared to MRE™

    • Marines consumed approximately 300 additional calories when consuming the NOFSR

  • Overall Marines were not eating enough

    • Lack of time

    • Didn’t really equate food to performance

  • Preliminary data from 2nd study supports trends suggesting that FSR™ items better sustain mood and alertness

  • Spiral development insertions to provide the best for our Warfighter in the field
