競技桌球專項有氧測驗之信效度分析
Analysis of Reliability and Validity of the Competitive Table Tennis-Specific Aerobic Test
摘要
有氧耐力是競技桌球運動員的一項重要能力，先前研究尚未發展具信度與效度的專項運動測驗。本研究目的為使用再測信度、同時效度及建構效度分析新建立的競技桌球專項有氧測驗（competitive table tennis-specific aerobic test, CTTSAT），以確認檢測方法可評估競技桌球專項有氧能力測量特性，並能區別不同年齡與層級的競技桌球選手。首先以10位大專公開組選手於相同時間且間隔7天進行兩次CTTSAT；接續以24位大專公開組、24位U16～18青少年組、24位U13～15青少年組，以及24位大專一般組桌球選手分別參與CTTSAT與多階段20公尺折返跑測驗之效度分析。測量總運動時間，並在運動前、測驗結束立即，以及恢復期間（3分鐘與6分鐘後）記錄心跳率、血乳酸濃度及自覺運動強度作為選手於CTTSAT表現與生理反應。研究結果顯示：總運動時間再測信度高。在同時效度上，CTTSAT與多階段20公尺折返跑測驗間顯示總運動時間與預估最大攝氧量為顯著正相關。在建構效度上，U16～18青少年組與大專公開組總運動時間皆顯著多於大專一般組，特別是U16～18青少年組亦有明顯較佳的血乳酸恢復效率。本研究結論指出CTTSAT為準確與穩定的檢測方法，同時能提供評估與鑑別4組競技桌球選手。

Aerobic endurance is important for competitive table tennis (TT) players. Prior research has not yet developed a reliable and valid TT-specific aerobic test. The purpose of this study was to analyze a new competitive table tennis-specific aerobic test (CTTSAT) by evaluating test-retest reliability, concurrent validity, and construct validity. The goal was to determine whether the testing method would be able to evaluate TT-specific measurement properties on aerobic capacity and effectively discriminate between competitive TT players in different ages and levels. First, 10 college level-1 players performed the CTTSAT simultaneously on two test occasions, separated by seven days. Then, 24 college level-1, 24 U16-18, 24 U13-15, and 24 college level-2 TT players participated in the validity analysis of the CTTSAT and multistage 20 m shuttle run test (20mMSRT), respectively. The total sporting times were measured. Heart rate, blood lactate concentration, and perceived exertion were recorded prior to the test, immediately after the test, and during the recovery period (3 and 6 minutes later) to determine the players' performance and physiological responses to the CTTSAT. For reproducibility, total sport time test-retest reliability was found to be high with an intra-class correlation coefficient. In concurrent validity, a significant positive correlation was found between total sporting time in CTTSAT and predicted maximal oxygen uptake. Regarding construct validity, the U16-18 group and college level-1 group had higher total sporting times than the college level-2 group, especially the U16-18 TT players also showed greater blood lactate recovery. We conclude that CTTSAT is a valid and reliable method for testing that differentiated among four-level competitive TT players.
