Scientists Studied the Thermoregulatory and Osmoregulatory Responses in Exercising Human

question 66

Multiple Choice

Scientists studied the thermoregulatory and osmoregulatory responses in exercising human subjects who were experiencing different levels of dehydration (0%, 3%, 5%, and 7% based on body weight) . After exercise, the subjects' body temperatures, sweating rates, and blood solute concentrations were measured. Their results are shown in these three graphs. Note that only sweating rate was measured after each bout of exercise. Body temperature was measured after the first two bouts of exercise, and blood solutes after only the first bout of exercise.

Definitions:

Deviations

Differences between observed values and some reference value, often the mean of the dataset, indicating the spread of the data.

Mean Squared

A statistical measure of the average of the squares of the errors or deviations, that is, the difference between the estimator and what is estimated.

Standard Deviation

A measure of the amount of variation or dispersion in a set of values.

Spread Out

Describes data that is dispersed widely, showing a large variation among its values, often seen in distributions with high variance.
