男子角力選手降體重期間無氧能力分析

本研究目的是男子角力選手在固定訓練模式下及飲食控制期間進行減重所產生的體重、身體組成、無氧能力及作用功率之差異分析。以男子選手10人為研究對象，平均年齡19.4 1.26歲、身高168.86 5.49公分、體重69.90 8.73公斤，運動年資7.50 1.90年，減重重量2.34 2.75公斤。在減重前、中、後，先以身體組成分析儀進行身體組成之脂肪百分率、脂肪重、基礎代謝率、身體總水量及肌肉重的變化紀錄。使用原地跑步機及乳酸分析儀分析乳酸值判斷無氧能力而兩次跑步時間予以紀錄並計算兩次跑步功率。所得的資料，使用單因子變異數分析（One-Way ANOVA）做資料處理，並就比賽結果，將獲獎選手及未獲獎選分為二組以獨立樣本T檢定作為統計方式α值設定為<.05。

結果：在減重期間選手的身體組成之變化，體重、體脂肪百分比、基礎代謝率、身體總水量及肌肉重，乳酸值及第一回作用功率並無顯著差異，在第二回作用功率上卻達到顯著差異，經Tukey法做事後比較減重前及減重中的第二回作用功率明顯優於減重中及減重後。獲獎選手與未獲獎選手在減重期間，體重、體脂肪百分比、基礎代謝率、身體總水量及肌肉重，乳酸值及第一回作用功率並無顯著差異未達顯著差異水準。在作用功率方面：減重前的第二回檢測發現，獲獎選手顯著的優於未獲獎選手，顯示獲獎選手有較佳的持續作功能力。

結論：角力選手在固定訓練模式下及飲食控制的減重期間對最重要之無氧運動能力、第一回作用功率及身體組成，並不會造成顯著影響。就獲獎選手與未獎選手之比較，亦是如此，對恢復後第二回作用功率是有顯著影響。因此角力選手在固定訓練模式及飲食控制下進行減重是可以進行的。

The purpose was to examine the effects of weight loss regiment on body mass, body composition, blood lactate, and anaerobic capacity in male wrestlers. Subjects were 10 male wrestlers (average age=19.4 ± 1.26 yrs; height=168.86 ± 5.49 cm; weight=69.90 ± 8.73 kg; athletic experience=7.50 ± 1.90 yrs) who have participated a routine training module and dietary manipulation to loss weight. Before, during, and after the weight loss regiment, percent body fat (PBF), fat weight (FW), basal metabolic rate (BMR), total body water (TBW), and lean body mass (LBM) were tested by body impedance analyzer (BIA). Anaerobic capacity was determined by treadmill running and blood lactate (bLA) measurements. Subjects were requested to perform two bouts of running and the running time was collected and work rate (WR) was calculated. One-way analysis of variance (ANOVA) was applied to processing the data. Tukey post hoc procedure was used to identify significant between groups. Independent t-test was performed to examine the difference between successful and none-successful wrestlers. Significant level was set atα<0.05. Results have shown that PBF, FW, BMR, TBW, and LBM of the subjects were not change throughout the study. bLA and WR was no significant change during first bout of exertion and reached significant level during second bout of running. Tukey tests compared WR of second bout running before, during, after weight loss and found a higher WR before the regiment. Successful and non-successful wrestlers were found not difference in PBF, FW, BMR, TBW, and LBM, bLA, and first bout WR. Successful wrestler demonstrated a higher bLA clearance rate during second bout of running before the regiment started. In conclusion, the routine training module and dietary manipulation to loss weight have not significant change of exercise performance in wrestlers in this study. Therefore, this weight loss regiment may feasible for weight-classified wrestling athletes.
