Prevention and rapid recovery of fatigue of officers and soldiers from plateau with amino acids and vitamins

Objective The present paper is a report of investigation of prevention and rapid recovery of fatigue rate of officers and soldiers on a plateau caused by military operations with the aid of amino acids and vitamins.Methods The participants were 100 officers and soldiers,whose Modified Fatigue Rating Scale(MFIS) scores were 21 points.The participants were randomly divided into three groups: capsule,placebo,and granules.Amino acids capsule,placebo,or amino acid-fructose beverage was given to respective group for 14 days continuously.The scores of a 3000 m race of the officers and soldiers stationed on a plateau was measured on the first and 14th days.The maximal grip strength of the right hand,fist-making times per minute,and the height reaching by the hand after three steps for the same candidate were observed before and after fatigue loading(3000 m race).The blood levels of lactic acid and urea nitrogen of the candidates were measured after fatigue loading on the first and the 14th days.Results The 3000 m race results of officers and soldiers in the capsule and granules groups on the 14th day were better than that of the first day(P0.05),whereas no significant difference was noted in the placebo group(P0.05).The difference between the capsule and the granules groups in grip strength,fist-making times per minute,and hand reaching height on the 14th day were obviously lower than that on the first day(P0.05),whereas no significant difference was observed in the placebo group(P0.05).The blood levels of lactic acid and urea nitrogen in the capsule and granules groups on the 14th day were lower than that on the first day(P0.05),while there was no significant difference in the placebo group(P0.05).Conclusions Amino acids and vitamin preparations can obviously improve the military performance capacity of officers and soldiers stationed on the plateau.Similarly,they can effectively prevent the lowering of jumping ability and grip strength caused by military fatigue.Therefore,amino acids and vitamin preparations play an important role in the prevention and rapid recovery of fatigue in servicemen stationed on plateau.
