Shooting ability is an important aspect of performance in some sports and is vital during a military operation. Load carriage, clothing, and equipment normally associated with fatigue and reduced field of vision or lack of stability at a specific point are important factors that affect the ability to aim when shooting. Additionally, gun support and equipment appear to differentially affect shooting ability with varying shooting positions. All of the studies examining these factors have taken place on dry land and not in water. However, up to date, no study has examined the effect of wet conditions, especially after surface combat swimming (sCS), on shooting ability in different shooting positions. The purpose of this study was to determine the effect of fatigue, produced by prolonged sCS, on a fighter's shooting ability. In addition, we investigated whether the effect of fatigue and wet conditions differed between the shooting positions.
Forty-five participants performed 10 shots in a shooting simulator while standing (ST) and 10 shots while kneeling (KN). This was performed twice and in three conditions: dry, wet, and after 1,000 m of sCS.
Wet conditions did not significantly affect shooting abilities. Surface combat swimming negatively affected shooting ability when both ST and KN. The reduction in the center of gravity (COG) of the shots after sCS was 3.7 ± 2.5% for ST and 3.5 ± 0.8% for KN (P < .01). This was accompanied by the increase in horizontal and vertical movement of the gun after the sCS (P < .01). Kneeling was more stable, as shown by a higher percentage of COG of the shots by 3.3 ± 0.1% (P < .01) and by fewer gun movements in both axes (P < .01).
In conclusion, combat swimming affects shooting ability, both in ST and in KN positions. The KN position provides better stability and improved shooting ability.
射击能力是某些体育运动表现的重要方面,在军事行动中也至关重要。通常与疲劳、视野受限或特定点的稳定性不足相关的负重、服装和装备是影响射击瞄准能力的重要因素。此外,枪支支撑和装备似乎会因射击姿势的不同而对射击能力产生不同影响。所有研究这些因素的实验都是在陆地上进行的,而非在水中。然而,截至目前,尚无研究考察潮湿环境,尤其是水面战斗游泳(sCS)后,对不同射击姿势下射击能力的影响。本研究的目的是确定长时间sCS产生的疲劳对战士射击能力的影响。此外,我们还研究了疲劳和潮湿环境的影响在不同射击姿势之间是否存在差异。
45名参与者在射击模拟器中进行射击,站立(ST)姿势下射击10次,跪姿(KN)下射击10次。每种姿势在三种条件下各进行两次射击:干燥环境、潮湿环境以及1000米sCS之后。
潮湿环境对射击能力没有显著影响。水面战斗游泳对ST和KN姿势下的射击能力均有负面影响。sCS后,ST姿势下射击重心(COG)降低3.7±2.5%,KN姿势下降低3.5±0.8%(P<.01)。同时,sCS后枪支在水平和垂直方向的移动增加(P<.01)。跪姿更稳定,表现为射击COG百分比高出3.3±0.1%(P<.01),且枪支在两个轴向上的移动更少(P<.01)。
总之,战斗游泳会影响ST和KN姿势下的射击能力。KN姿势提供了更好的稳定性并提高了射击能力。
