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.目 次 第壹章…………………………………………………………………1 緒論…………………………………………………………………1 第一節 研究背景…………………………………………………1 第二節 研究目的…………………………………………………2 第三節 研究假設…………………………………………………2 第四節 名詞解釋…………………………………………………3 第貳章 文獻探討……………………………………………………4 第一節 網球運動之能量來源……………………………………4 第二節 補充NaHCO3對運動的影響………………………………5 第三節 酸鹼值與乳酸代謝………………………………………10 第參章 實驗步驟與研究方法………………………………………13 第一節 實驗對象…………………………………………………13 第二節 實驗設計…………………………………………………13 第三節 運動測試…………………………………………………14 第四節 生化分析…………………………………………………16 第五節 資料處理…………………………………………………16 第肆章 結果…………………………………………………………17 第一節 受試者基本資料…………………………………………17 第二節 實驗監控…………………………………………………17 第三節 血液生化…………………………………………………17 第四節 運動能力…………………………………………………18 第伍章 討論…………………………………………………………20 第一節 血液酸鹼平衡……………………………………………20 第二節 運動表現…………………………………………………22 第陸章 結論與建議…………………………………………………25 第一節 結論………………………………………………………25 第二節 建議………………………………………………………25 參考文獻………………………………………………………………27347228 bytesapplication/pdf碳酸氫鈉;緩衝能力;網球表現測試sodium bicarbonate;tennis performance;buffer capacity優秀大學網球選手補充NaHCO3對模擬比賽後技術表現之影響EFFECT OF SODIUM BICARBONATE SUPPLEMENTATION ON TENNIS SKILL PERFORMANCE AFTER A SIMULATED MATCHthesis
