女子排球選手光動敏捷能力表現之研究

Study of the Light Driving Agile agility for women's volleyball player

目的：光動敏捷測驗 (Light Driving Agile；LDA) 的定義是透過燈光媒介做為驅動全身性快速移動身體的理論基礎。LDA 促使人體快速的傳導神經訊號，經由大腦做出判斷並發出指令讓全身性快速移動身體，表現出敏捷性的運動表現能力。本研究是透過 LDA 測量隨機 8個方向 (8 Direction；8D)敏捷性表現能力，探討大專與高中甲級女子排球選手在各向度敏捷能力上的差異。方法：本研究以大專與高中排球甲級女子各 30名為研究對象，透過 BLAZEPOD 智慧性光動系統，進行 8D (往返) 敏捷性測驗，比較大專組與高中組差異性。結果：在 8D (往返)整體反應時間，大專組與高中組在 8個方向敏捷性表現能力皆向左移動較快，大專組 TRT 為 2.95 ± 0.56秒，高中組TRT為 3.22 ± 0.54秒，而速度較慢方向大專組向後移動LDA為 3.29 ± 0.45秒較差，高中組向前移動 LDA 為3.60 ± 1.06秒較差，兩組相較之下大專組 LDA 表現能力整體反應時間比高中組快。進一步將參數標準化，以百分等級平均值比較兩組，其中高中組整體平均值比大專組快，與秒數參數結果相異，經由本研究數據分析以百分等平均值標準化各個方向數據結果，顯示出不同層級選手敏捷性表現的差異。結論：在大專組、高中組 LDA 測量隨機 8D敏捷性表現能力，可以知道不同層級選手之間各個方向所花的時間有多少、差距，而可以藉此定義選手多方向的層級能力。

 

Purpose: The Light Driving Agile (LDA) was the theoretical basis for driving the whole-body agility through light medium. LDA promotes the rapid transmission of the human body as a neural signal. The brain makes judgments and issues instructions to allow the body to move the body quickly, showing the agility performance. This study was used LDA to investigate the 8 Directions (8D) agility differences of women’s volleyball players in University and high school level. Methods: 60 first-tier women’s volleyball players of university subject (n=30) and high school subject (n=30) were participated in this study. Agility test through intelligent BLAZEPOD system, at random the eight-direction run of agility of intelligent program, with Bluetooth signal trigger LED sense-disk device, dynamically indicate the direction of fast movement of the human body. In total, each participant were finish 48m of running distance with 16 turning points. Starting from the center point participants must ran towards the light up pod then return to the central position after each hit by hand. Used the SPSS software 17.0 for independent-test and Mann-Whitney U test were used to investigate the difference 8D ability of the two groups. Results: Based on the Total LDA Response both the university group and the high school group showed the fastest performance in the left direction with 2.95 ± 0.56 seconds and 3.22 ± 0.54 seconds respectively. Moreover, both the university group and the high school group were the slowed on moving backwards with 3.29 ± 0.45 seconds and 3.60 ± 1.06 seconds, respectively. The overall response time showed university group have better performance than the high school group. In comparison, the high school group showed better performance than the university group when the overall response time gets standardize using the percentile of their groups average. Conclusions: 8D agility performance able to measure how much time spend in the different directions which can define the player’s ability. In the future, more intensive training for the slower direction can be done by LDA to improve the players’ agility.
