The influence of negative air ions on rectal temperature (Tr), heart rate (HR), oxygen uptake (VO2) and ventilation (VE) was examined in male subjects (n = 8) at rest and during two successive exercise bouts of 90 W and 180 W, each for 20 min on a cycle ergometer. Exposures at 4 different times of day (01:30, 10:00, 14:00 and 18:00 h) were presented to subjects under experimental and control conditions using a cross-over design. Results indicated that negative air ions significantly reduced… CONTINUE READING
