手套介面對國軍閱兵托槍訓練之上肢肌力及疲勞程度的影響

本研究主要探討手套材質介面對於軍校生閱兵托槍練習之手部/前臂疲勞度的影響。首先對於軍校學生托槍練習後之身體活動動作難易度的主觀感受（無法上舉、抓握、不自覺抖動），及手套是否具有手部疲勞改善功能的主觀感受進行問卷調查，共發放60份問卷，男女各30位。結果顯示，超過七成受試者均有托槍練習後手部抖動與無法正常上舉、抓握之情形；同時亦主觀認為手套材質與手部疲勞相關，且有防滑顆粒的手套會較無顆粒的手套更能減少疲勞，尤其女性感受更較男性強烈。依據上述問卷結果，從中再挑選40位學生（男、女各20位）進行手套托槍實驗，探討手套（徒手、有顆粒、無顆粒）對手及前臂力量變化與主觀疲勞感受程度之評估。實驗要求受試者托槍20分鐘，觀察托槍前、後之握力與前臂曲屈提舉力之差異（視為客觀疲勞），托槍期間每5分鐘利用伯格量表蒐集身體不同部位之主觀疲勞感受程度。結果顯示，不同手套對手及前臂力量變化並年顯著影響，但主觀疲勞方面，空手之主觀疲勞程度顯著高於穿戴手套（有顆粒、無顆粒）；不論性別與穿戴手套與否，各部位（肩膀、上臂、前臂、手腕、手掌）的疲勞程度均隨著托搶時間增長而顯著增加。在客觀疲勞（托槍前後、握力下降）及主觀疲勞方面，女性皆顯著高於男性，其原因可能女性對於槍枝重量先天上握力及提舉力顯著小於男性所致。對於管訓單位則可視肌肉疲勞部位及程度，實施局部重點強化訓練，以提升訓練成效，而對於女性有負荷過重之現象，建議能改以較輕之槍取代，或進一步篩選上肢肌力較佳者並輔以較長之訓練等，而手套則僅有心理主觀的影響，或許能再進一步其他不同手套之效果。

The study examined the effect of glove interface on the fatigue associated with hands/ forearms after training for holding a gun in military parade. First of all, the result from a 60-subject questionnaire indicated that most of them felt fatigue on hands/ forearms after the training, especially females. Over 70% of all subjects also indicated that wearing gloves and their surface characteristics would change the fatigue felt. According to the questionnaire results, an experiment was designed to assess the effect of gloved condition on the fatigue associated with hands/ forearms after 20-min training of statically holding a gun. Forty subjects randomly selected from previous 60 subjects participated in the experiment. The responses were both objective and subjective fatigue. The objective included the decrease on both strength of handgrip and elbow lifting; the subjective was evaluated by Borg’s CR10 scales on five body parts (shoulder, upper arm, forearm, wrist, and palm) every 5 minutes. Three gloved conditions including bared and gloves with smooth surface or not were evaluated. The t-test showed that males had greater strength on handgrip and elbow lifting than females. A paired t-test further demonstrated that a significant decrease on both strength was found, which implied that the training did cause a muscular fatigue. The ANOVA result indicated that the gloved effect was not significant on both strength degenerations, but females had more decrease on handgrip strength. On the other hand, the subjective fatigue evaluated by Borg’s CR-10 dramatically increased with holding time regardless of both gender and gloved effects, and wearing gloves and females had less subjective fatigue felt as compared with bared condition and males, respectively. The possible reason for gender effect was that females generated less handgrip and elbow lifting strength than males, so more fatigue felt by females when the weight of gun was the same. In addition, wearing gloves was recommended for less subjective fatigue felt perhaps due to less weight pressure acting on palm. Training units can execute enforcement training on some mainly body parts or provide effective methods based on the levels of muscular fatigue in order to promote training effectiveness. To solve the problem of females with overload, we suggest using lighter guns to replace heavy ones, selecting females with stronger arms or lengthening training periods. Finally, gloves only have subjective mental impact, and perhaps other types of gloves can be further discussed.
