Physical activity for pregnant women should be controlled and adapted in order to minimize the risk of loss of balance and fetal trauma (Davies, Wolfe, Mottola, y MacKinnon, 2003). Noninvasive technologies are required for understanding better the effects of physical activity on pregnant women. Infrared thermography allows, remotely, securely and without any contact, to measure and display accurate temperatures on the human skin. Methods: We studied the effect of two different organized physical activities on the skin temperature (Tsk) of 28 volunteer 31-weeks-pregnant women (Yoga: n=14; Swimming: n=14). Two sets of six thermograms (Anterior and Posterior of the Upper and Lower limbs, and Left and Right Lateral Upper body) were registered by a T335 FLIR infrared camera: the first after 10 minutes of acclimatization to the room conditions and before the physical activity, and the second within the ten minutes after finishing the physical activity. Results: Because of the significant difference in general Tsk of the women in the first assessment (t(26) = 9.21; p < 0.05) probably due to increased use of creams (?2(1) = 9.33; p < 0.05), lower room temperatures (t(26) = 4.00; p < 0.05) and humidity (t(26) = 7.49; p < 0.05) in the yoga group, only the increment of Tsk between pre- and post-activity measurements were considered for the analysis of the data. Our results indicate (see Table 8) that general Tsk were significantly reduced after swim-ming (t(13) = 11,60; p < 0.05) and non-significantly increased after the yoga practice (t(13) = -1,19; p = 0.25). This tendency was similar in all the body areas in the Swim group and more heterogeneous after the yoga practice with non significant differences in the limbs and significant differences in the trunk areas (including breast and belly). Conclusions: The results point out a significant reduction of Tsk of expectant mothers after aquatic activity even in the breast and belly areas, probably due to inadequate water temperature although the values of Tsk does not appear to be hazardous to the fetus. Practicing yoga during pregnancy slightly increases the Tsk in the whole body maybe because of the characteristics of the activity.
