研究背景與目的：本研究希望檢測中高齡職業客運駕駛工作相關體能，建立我國中高齡職業客運駕駛之相關體能資料庫，供維護職業駕駛工作能力或健康促進策略之參考。研究方法：本研究針對306名40歲以上職業駕駛進行問卷調查、體能檢測（包括視野、聽力、肌力、活動度、平衡能力、反應能力等）及交通事故次數、違規次數調查。結果：年齡超過60歲之駕駛，在兩側手握力（與＜45歲、45~49歲、50~54歲三組比較，P<0.05）、單腳站的平衡能力（左腳與＜45歲、45~49歲、50~54歲三組比較，P<0.05；右腳與＜45歲比較，P<0.05）、通過視聽反應的平均時間（與45~49歲、50~54、55~59歲三組比較，P<0.05）、優耳之高頻聽力闕值（與＜45歲比較，P<0.05）、心智狀態量表分數（與＜45歲、45~49歲兩組比較，P<0.05）等項目的確較年輕之駕駛族群差；且60歲以上近一年曾發生事故的人數百分比亦較多，但無顯著差異。結論：年齡對駕駛能力而言，為一綜合性影響，非單一體能項目可區辨。

Background and Purpose: This study aimed to find the testing battery to evaluate the physical conditions of middle-aged and elder professional drivers, establish the database, and to provide the consultations of professional drivers' working ability or to provide the policies of healthy promotion. Methods: This study recruited 306 drivers aged more than 40 years. The collected data included basic demographic data, presence of chronic illness, physical examination including visual field, hearing, grasp power, limitation of joint range, balance, reaction time, and the records of traffic accident and violation of traffic rules. Results: The results showed aged drivers (≥60 years) had worse performance at bilateral grasp power (p<0.05, compared with <45, 45~49 and 50~54 years group), balance of single leg stand (p<0.05, compared with <45, 45~49, and 50~54 years group for left leg; <45 years group for right leg), means of visual-audio passed reaction time (p<0.05, compared with 45~49, 50~54 and 55~59 years group), high frequency hearing threshold of better ear (p<0.05, compared with <45 years group) and mental status (p<0.05, compared with <45 and 45~49 years group). The aged drivers had more traffic accidents than the other drivers (<60 years) in the recent one year, but not statistically significant. Conclusions: Aging has an overall effect on physical functions. No single physical fitness test can measure all effects of aging on driving.
