預防運動傷害一直是體能訓練領域的熱門議題,而核心穩定能力是預防運動傷害不可或缺的因素,它是同時兼具影響運動表現與傷害預防的重要指標。在運動過程中,核心肌群扮演著穩定動力鏈與協助傳遞力量的重要角色。核心肌群中的脊椎旁肌群(例如:多裂肌等),由於肌梭比率含量頗豐,更是感受身體姿態、提供本體感覺與調整肌肉張力的重要感受器。從過去許多研究發現,核心穩定能力不足將出現動力鏈的力量傳遞不順暢,並導致遠端肢段控制能力不佳,因而使得上肢或下肢關節負荷上升,降低運動表現與增加傷害風險。透過不穩定平面的訓練方式誘發核心肌群與動力鏈的整合,是目前正熱門的運動訓練議題,學界透過研究結果發展出多種不穩定平面的訓練方式,在眾多訓練器材中,懸吊式訓練似乎最能有效提升肌肉活性並增加神經肌肉控制能力;透過閉鎖式動力鏈之動作,提升在運動過程中軀幹的穩定能力,同時整合選手的本體感覺與全身性動力鏈的力量串聯能力,透過肌筋膜理論的連動特性可發現,核心肌群的力量與穩定能力間接影響了下肢的運動表現,但目前尚未有研究證實懸吊式核心訓練對下肢傷害預防之實證性研究,故建議未來研究計畫,觀察藉由懸吊式核心訓練增強核心與髖關節的肌力、神經肌肉控制能力,是否能達到提升運動表現同時預防下肢傷害之效益。
Core muscle function and core stability had attract highly attention among athletic training and performance enhancing in past two decades for it is a remarkable indicator highly relevance to exercise performance and injury prevention. As body performing exercise, core muscle groups not only act as force transducer but also as stabilizer between upper and lower limbs. Further more, paraspine muscle such as multifidus, for it muscle spindle rich nature, work as tension detector while cerebellum coordinating trunk muscles thus to link muscles from lower limb to upper limbs to work together as a kinetic chain and vice versa. Numberous of previous studies indicates that insufficient core stability will result to poor power transduction, decrease exercise performance and possibly increase injury ricks of the distal joints such as knee and shoulder. As present, several training programs using unstable surface training to increase core stability have been developed. Among all those training programs, suspension exercise seems to more effective in facilitate muscle activation and improve neuromuscular control. With close-kinetic chain nature, suspension exercise facilitating trunk muscle activation and participation during exercise thus to provide stability and effectively force transduction. Furthermore, through the interlocking characteristics of myofascial fascia, well-activated trunk muscles indirectly affect the performance of the lower limbs. We collected research document as best we can research to discuss about relationship of trunk muscles activation and performance of lower limbs. Also we will discuss about effects of suspension exercise on trunk muscle activation and lower limbs performance.
