本研究目的在於暸解身體活動對孕婦之體重增加量、血壓、安靜心跳率及血液生化值的影響。本研究受試者為高雄市居民，皆為懷孕三十週以土之婦女，計66位。依懷孕前和懷孕中身體活動情形，將受試者分為A-A紅(懷孕前和懷孕中身體活動度皆高者，22人，平均年齡25.2土4.4歲)、A-I組(懷孕前 身體活動度高而懷孕中則無規律身體活動者，14人，平均年齡25.4土4.6歲)、 I-A組(懷孕前身體活動度低而懷孕中規律從事身體活動者， 19人，平均年齡 25.9土3.8歲)及I-I組(懷孕前和懷孕中身體活動度皆低者'11人，平均年齡 28.8土5.2歲)等四缸。 本研究有關血液生化值的測量，由成功婦產科實施。所得各資料以Two-way ANOVA處理之，結果如下: 一、不論懷孕前身體活動情形如何，懷孕中若有從事規律的身體活動者，其體重增加壘、心縮壓、心舒壓和安靜心跳率皆顯著低於無從事規律身體活動者(體重增加壘:7.6 VS. 11.1 kg ;血壓:111/68 VS. 121/77 mmHg ; 安靜心跳率:84 VS. 88次/分)。 二、不論懷孕中身體活動情形如何，懷孕前身體活動度高者其心縮壓和安靜心跳率皆顯著低於懷孕前身體活動度低者(心縮壓:113 VS. 119 mmHg ; 安靜心跳率:84 VS. 87次/分)。 三、懷孕前身體活動度和懷孕中身體活動對紅血球數目、血紅素、白血球數目及血球容積比等值，皆無顯著影響。由以上結果，本研究得到以下結論:懷孕前和懷孕中的規律身體活動，皆可使母體安靜心跳率和體重增加量較一般孕婦為低。故本研究認為孕婦在懷孕前應保持規律身體活動，以減少體重增加太多的困擾，並提昇體過能。

The purpose of this study was to investigate the effects of physical activity on weight change， blood pressure， resting heart rate， and blood parameters (red blood cells count， hemoglobin， white blood cells count， haematocrit) in a sample of pregnant women (n=66). Subjects were residents of kaushung city and all agree to participate in this study. The subjects were all above 30 weeks in pregnancy (x=33.5 ± 3.5 weeks). The subjects were divided into four groups according to their before and during pregnant levels of physical activity or inactivity: A-A (Active-Active， n=22)， A-I (Active-Inactive， n= 14)， 1- A (Inactive-Active，n=19)， and I-I (Inactive-Inactive， n=ll). A two-way ANOV A was utilized to analyze the data using 0.01 level of significance. The results are listed fOllowing: 1.The weight changes， blood pressure， and resting heart rate of the physically active group during pregnancy were significantly lower than the inactive group (P < .01). 2. The resting heart rate and the systolic blood pressure of the physically active group before pregnancy were significantly lower than the inactive group (P < .01). 3. There is no significant difference in blood parameters (red blood cells count， hemoglobin， white blood cells count， haemotocrit) resulting from physical activities of before or during pregnancy. Judging from the above results， we find that the physical activities engaged before or during pregnancy can have lower resting heart rate than other pregnant women， but the physical activities engaged during pregnancy will result in having less weight gain. Therefore， the study suggests that women should improve their physical fitness before pregnancy and stop doing intense exercise during pregnancy.
