dc.description.abstract　　氫離子的囤積是造成疲勞的主要原因之一，疲勞可能會使網球球員無法到達適當的擊球位置，或造成擊球點與擊球時間的錯誤，而影響技術表現。而NaHCO3補充可能可以增加細胞外的緩衝能力，進而減少運動所累積的氫離子，達到提高技術能力。本研究目的為探討NaHCO3補充對於優秀大學網球選手在模擬比賽後技術表現之變化。以9名男性網球運動員(平均年齡21.8歲，身高173.1公分，體重68公斤)為研究對象，每位受試者均完成NaHCO3組與對照組試驗。每一次實驗均進行約60分鐘的模擬比賽，於模擬比賽前後各進行一次網球表現測試（Loughborough Tennis Skill Test, ST）。ST將評估受試者在發球、底線抽球之技術能力。模擬比賽包含12局，型態包括發球或接球、底線抽球與截擊，NaHCO3組於運動前70分鐘攝取0.3 g/kg，並在模擬比賽之第三局休息時補充0.1g/kg NaHCO3，攝取前和模擬比賽後採集血液樣本與對照組進行統計分析。乳酸具有顯著時間及時間和處置之交互作用效應，碳酸氫根具有顯著處置與時間和二者交互作用效應，BEB具有顯著處置與時間和二者交互作用效應。pH具有顯著處置與時間和二者交互作用效應，於模擬比賽後各生化值NaHCO3組均顯著高於對照組。ST 發球總得分、第一發球區與正手拍底線抽球具有顯著交互作用效應。結果顯示，NaHCO3 補充能增加細胞外緩衝能力，並增加優秀網球選手在模擬比賽後ST的表現。
dc.description.abstract　　The accumulation of H+ is one of the major causes of fatigue. It has been shown that NaHCO3 supplementation may increase extracellular buffer capacity, reduce exercise-induced H+ accumulation, and enhance exercise performance. The aim of this study was to investigate the effect of NaHCO3 supplementation on skilled tennis performance after a simulated tennis match. Nine male college tennis players were recruited (mean age 21.8 years, height 1.73 m, weight 68 kg). Each subject completed a bicarbonate trial (BIC) and a placebo trial (PLA) in a randomized order, separated by one week. Subjects performed 2 tennis skill tests before and after the simulated game in each trial. The skill test evaluated the accuracy and consistency of service and ground stroke to both sides of the court as previously described (Davey et al, 2002). The simulated match consisted of 12 games. Each game contained 36 hit balls, including forehand and backhand ground strokes and volleys. The subjects consumed NaHCO3 (0.3 g/kg) or placebo (NaCl, 0.209 g/kg, equal amount of Na) 70 min before the first skill test. Each subject also ingested 0.1g/kg NaHCO3 or 0.7g/kg NaCl after the third game of the simulated match. Biochemical parameters in arterialized venous blood were measured by autoanalyzers. There were significant time and trial x time effects in plasma lactate concentration. Lactate concentrations were significantly increased after both trials with BIC showing higher increase (pre-match: 1.22±0.54, post-match: 2.17±1.46 in PLA; pre-match: 1.23±0.41, post-match: 3.21±1.89 mM in BIC). The significant trial, time, and trial x time effects were present in bicarbonate concentration. Bicarbonate concentration remained unchanged after PLA but was significantly elevated after BIC (pre-match: 27.99±2.02, post-match: 26.37±3.50 in PLA; pre-match: 28.84±2.16, post-match: 37.98±3.95 mM in BIC). Trial, time, and trial x time effects were significant in OxyBE. OxyBE was significantly lower after PLA (pre-match: 2.46±1.68, post-match: 0.12±2.15 mM) but was significantly elevated after BIC (pre-match: 3.08±1.47, post-match: 11.36±3.70 mM). The trial, time, and trial x time effects were also significant in blood pH. Blood pH remained unchanged after PLA but was significantly elevated after BIC (pre-match: 7.37±0.32, post-match: 7.37±0.14 in PLA; pre-match: 7.37±0.26, post-match: 7.45±0.63 in BIC). In the skill test, significant trial x time effect was present in service consistency. The service consistency was significantly decreased after the simulated match in PLA (pre-match: 8.56±2.83, post-match: 5.56±3.00), but remained unchanged in BIC (pre-match: 7.00±2.78, post-match: 6.89±3.14). The results suggested that NaHCO3 supplementation could increase extracellular buffer capacity and increase skilled tennis performance after a simulated match.
