摘要

本研究之目的主要探討男子運動選手的核心肌耐力、動態平衡、運動表現和身體淨組織重量間的相關性。方法：本研究招募19名男子田徑跳部與跨欄選手，透過測量其核心肌耐力（棒式、橋式和側棒式）、Y字動態平衡能力和運動表現（垂直跳高、立定跳遠、單足五級跳躍以及藥球前拋與後拋），並使用雙能X光測量儀，進行全身及各部位之身體組成測量，以皮爾森積差相關分析各變項間的相關性，顯著水準定為p＜.05。結果：一、棒式核心肌耐力，與立定跳遠、慣用腿和非慣用腿單足五級跳，有顯著負相關；二、非慣用腿Y字動態平衡能力，與垂直跳高有顯著正相關；三、全身及各部位淨組織重量，與垂直跳高爆發力有顯著的正相關。結論：對於以速度和爆發力為主之選手而言，有較佳的核心肌耐力，並未對其下肢和全身性爆發力有直接正面的意義，甚至會有負面的影響；而下肢動態平衡能力與腰部淨組織重量較良好之選手，對下肢和全身性爆發力具有重要的意義，因此建議教練或選手，可針對下肢動態平衡能力和腰部肌群之肌肉量，進行專門性的訓練。

The purpose of this study was to investigate relationships between core endurance, dynamic balance, athletic performance, and lean tissue mass of male competitive athletes. Methods: Nineteen male collegiate track and field jumpers and hurdlers were recruited, by measuring their core endurance (plank, bridge and side plank), Y dynamic balance test and athletic performance (vertical jump, standing long jump, five consecutive hops, forward medicine ball throw, and backward medicine ball throw), and using the dual-energy X-ray absorptiometry for the assessment of body composition (total and regional lean tissue mass). Pearson's product-moment correlations (r) were used to evaluate relationships amount pairs of test variables, with statistical significance was set at p ＜ .05. Results: (1) There were significant negative correlations between plank core endurance and standing long jump, dominant leg, and non-dominant leg five consecutive hops; (2) There was significant positive correlation between non-dominant leg Y dynamic balance ability and vertical jump; (3) Lean tissue mass of the total body, arms, torso, waist and buttocks which were found a significant positive correlation with vertical jump explosive power. Conclusion: As to athletes expertise mainly on speed and explosive power, better core endurance was found no direct positive impact to their lower limb and whole body explosive power, even worse, negative influences were found, however lower limbs dynamically balance ability and lean tissue mass of the waist may have important significance impact on the athletes' explosive power of their lower limb and whole body. Therefore it is recommended that coaches or athletes should conduct training program particular on the lower limb dynamically balance ability and the muscle mass of the waist muscle group.
