Physiological Response To Exercise With Naturally-Occurring Carbon Dioxide Exposure, Megan Johnson

BACKGROUND: Carbon dioxide (CO2) plays a normal part in gas exchange and acid-base equilibrium in the human body. With added stress or exposure, CO2 levels can accumulate in the blood and tissues, causing hypercapnia. Research has shown that exposure to CO2 at 4% or 40,000 ppm will cause cardio-respiratory changes, both at rest and during exercise. Lower levels may still cause changes under conditions of added stress, but this has not been elucidated. Preliminary data from our laboratory chamber suggests physiological changes at levels of CO2 reaching 0.08% or 8,000 ppm during experiments with exercising …

Effects Of 7°C Environmental Temperature During A 3-Week Training Period, Robert J. Shute

Approximately three weeks is required for cold temperature acclimation to occur. However, the effects of cold temperature acclimation on fitness and performance remain unknown. Purpose: To determine the impact of cold environmental temperature on training adaptations, fitness measurements, and aerobic performance. Methods: Two groups of twelve inactive male subjects completed 1-hour of cycling in fourteen temperature acclimation trials of either a cold (7°C) or room temperature (20°C) environmental temperature. A performance trial and tolerance trial occurred pre- and post-acclimation. The performance trials assessed VO2peak and body composition. Skin and core temperature were recorded during the 1-hour tolerance trials. Tympanic …
