本研究的目的在(1)比較長距離捷泳所導出之臨界速度與短距離捷泳所導出之臨界速度是否有差異;(2)探討不同距離組合之臨界速度與捷泳成績之相關。受試者為21名大專甲、乙組游泳選手(年齡=21.1±1.37歲,身高=168±6.19公分,體重=64.2±8.27公斤)。所有受試者須分別接受兩次25、50、100、200、400和800M最大努力捷泳測驗及漸增速度心跳閾值測驗。以不同距離組合(CV251:25、50和100M;CV512:50、100和200M;CV248:200、400和800M以及CV25-800:全部)依D=CV×t+ASC直線模式計算出臨界速度(CV)與無氧游泳能力(ASC)。結果顯示CV251、CV512、CV248、CV25-800以及心跳閾值速度的平均速度依序為1.37±0.18、1.19±0.19、1.10±0.18、1.13±0.18、和1.17±0.17(m/s)。心跳閾值速度及所有不同組合的臨界速度之間的相關皆達顯著水準(0.87以上,p<0.01),但CV251與其他速度之間皆達顯著差異。結果也顯示,除了CV251外,CV512、CV248及CV25-800和心跳閾值速度皆與中、長距離捷泳成績表現有極高的相關,可作為游泳運動表現的預測指標。
本研究結果顯示,在實用上可測量50公尺、100公尺、和200公尺捷泳成績來評估臨界速度。
The purpose of this study was to investigate: (1)the difference and relationship of critcial velocity (CV) derived from short-distance and long-distance front crawl swimming performance, (2)the relationships among CV derived from different distance front crawl performance combinations. Twenty-one trained swimmers with mean age, height and body weight of 21.1(SD=1.37)yrs, 168(SD=6.19)cm,and 64.2(SD=8.27)kg, respec-tively were studied. All subjects were instructed to swim six different distances (25m, 50m 100m, 200m, 400m, and 800m)at maximal effort twice. The CV and anaerobic swimming capacity (ASC)were obtained from four different combinations (CV251:25m, 50m and 100m; CV512:50m, 100m and 200m; CV248, CV25-800:25m, 50m, 100m, 200m, 400m and 800m). All subjects took progressively increased speed front crawl swimming test to measured heart rate threshold velocity (HRTV). The swimming velocities (mean±SD m/sec)among CV251, CV512, CV248, CV25-800 and HRTV were 1.37(0.18),1.19(0.19), 1.10(0.18), 1.13(0.18), and 1.17 (0.17)in order. There were significant correlation(r>0.87, P<0.01)among CV251, CV512, CV248 CV25-800 and HRTV. All CV's and HRTV were significantly correlated to performance of all distances (P<0.01). Related t-test revealed that besides CV251, no significant differences among the CV's and HRTV. Highest correlation (r=0.99) was found between CV248 and long-distances front crawl performance (400m and 800m).
In conclusion, coaches and swimmers can measure 50m, 100m and 200m front crawl performance to determine critical velocity in practice.
