柔软度可以预防運動傷害的發生及提升運動表现，並可藉由熟身舆伸展運動來達到改善的效果。但有時在熟身與伸展完畢後，會因天候不佳或赛程冗長等因素使比赛無法如期進行，可能使柔软度效果受到影響。有鑑於此，本研究目的在探討熱身舆伸展運動封柔软度持續效果的影響。受試者爲40名健康及無骨骼肌肉系統疾患之男性學生，且所有受試者皆爲自願参與。平均年齡20.34±1.06歲，身高173.94±6.34公分、體重63.94±10.92公斤。以随機分派的方式将受試者分成四組：熱身組、伸展組、混合組、控制組。受試者首先静坐休息，以耳内温测量倦(THERMOSCAN PRO-1)测量受試者體温，以腕裱心跳率测定器(POLAR VANTAGE XL)测量受試者心跳率，以坐姿體前彎测量受試者柔软度。經前测俊：热身組以67.74±7.04%预测最大心跳率跑步10分鍾；伸展組以柔软度测驗方式静態伸展30秒，之俊休息30秒，重覆10次，共豁10分撞；混合組以67.66±6.71%预测最大心跳率跑步10分撞俊伸展10次（同伸展粗）；控制組则以坐姿方式休息10分鍾。在運動後所有受試者著短袖T恤及運動短褲坐在高度40公分之椅子上靠椅背休息，並於運動俊0、15、30、45、60分鍾各再测量一次。以混合設計二因子變異数分析實驗所得資料，若前测有差異時，再以單因子共變數分析法考驗後测結果。本研究所獲得結果發现：在運動俊第0分鍾時之柔软度變化，混合組高於熱身舆控制組，伸展粗高於挫制組(F=14.39, p<.05)。伸展與混合組柔软度在運動俊第0、15、30、45、60分鍾皆高於運動前（伸展組：F=20.76, p<.05；混合粗：F=39.07, p<.05）。本研究之結論爲伸展運動可改善暂時性柔软度，而伸展前配合熱身運動之改善效果最佳，且其改善效果可持續到運動俊60分鍾。

Flexibility can prevent the incidence injuries and improve the performance, it also can be improved the performance by warm-up (WU) and stretching exercise (SE). Due to the factor of bad weather or schedule delay, even had done the exercise of WU and SE, the athletic were unable to competing immediately cause the flexibility could be effected. The purpose of this study was to compare the influence of Warm-Up and static stretching exercise on flexibility sustained effect. Forty males (age 20.34±1.06 years, height l73.94±6.34 cm, weight=63.94±10.92 Kg) subjects who agreed to volunteer and could not have any history of pathology to hip, knee, thigh, or lower back. Each subject undertook the one of following protocols, in random order: (1) warm-up protocol(W); subjects was jogging at 400M in field for 10 mm at 67.74±7.04% of their maximum age predicted heart rate; (2) stretching protocol(S): ten 30's static stretches with 30's rest between stretches; (3) combined protocol(WS): subjects ran(at 67.66±6.71% of their maximum age predicted heart rate) first and then stretched; (4) control protocol( C ); rest 10 mm by sit on the chair. In pretest (Tp). use the thermoscope(THERMOSCAN PRO-1) to measure body temperature, use the polar(POLAR VANTAGE XL) to determine heart rate, and sit-and-reach to test flexibility. In the rest period, all subjects wore the T-shirt and sports shorts sit by the back of a chair (height =40 cm ) and at the after perform 0(T0), 15(T15), 30(T30), 45(T45), 60(T60) min test again. Data were analyzed a two-way (test × group) analysis of variance (ANOVA) with repeated measures on variable (test) and appropriate post hoc analyses. If the Tp had significant difference, used the one-way ANCOVA to analysis the posttest. The result of this study was the flexibility at T0, the WS was significant higher than W, S, C, and S significant higher than C (F=14.39, P<.05). The subjects of S and WS at Tp were significant lower than T0, T15, T30, T45, and T60. In conclusion, stretching exercise could improve the acute flexibility, and match the warm-up have the greater effect. The effect of the improving can maintain to 60 min after exercise.
