One healthy, female endurance athlete (BW = 64 kg) will perform two bouts of prolonged running exercise (90 min at 175 m/min) in an environmental chamber on 2 separate days under different conditions: 1) at 21 C and 2) at 34 C., each trial at 50% RH The subject has a maximal VO2 of 3.92 L/min. The subject will not consume any fluids during either trial.;If there are differences in the outcome variables between Trial 1 and Trial 2, address what factor(s) contribute to these differences.;Given the data in Trial 2 (34 C), at what point during exercise (i.e. if exercise continued), would the exercise become dangerous?;Explain your predicted BP (including systolic and diastolic) responses. If you predicted differences between trials, what factor(s) could explain these differences?;What could explain the unchanged VO2 from Trial 1 to Trial 2, even though Q is higher in Trial 2 vs. Trial 1?;Would you predict there to be differences in skin blood flow or muscle perfusion during the two trials?;What procedures/strategies may be used to minimize differences in thermoregulatory and cardiovascular outcomes between the two trials (assuming you cannot control the weather)?
