Figure 2

Changes in oxygen intake (VO 2 ) during cold exposure. White circles with the dotted line indicate summer data (n = 17, mean ± S.E), and black squares with the solid line indicate winter data (n = 17, mean ± S.E). In winter, VO2 tended to be greater during thermoneutral baseline and was significantly greater in the period ranging from 30 to 100 min during cold exposure than it was during those same periods in summer. In winter, VO2 was significantly greater after 40 min of cold exposure than it was during the first 10 min. In summer, VO2 was significantly lower after 30 min of cold exposure and tended to be greater after 100 min of cold exposure than it was during the first 10 min. P < 0.1, **P < 0.01 when summer and winter values were compared. # P < 0.05 when summer values were compared with the other summer values.
