Intro

A single bout of exercise.

A physiological change that occurs when the body is exposed to repeated exercise bouts over weeks or months. these changes generally improve the body's efficiency at rest and during exercise.

In an experimental design, the non-treated group to which the experimental group is compared.

Experimental design in which the control group becomes the experimental group after the first experimental period, and vice versa.

A research design in which a cross section of a population is tested at one specific time and then data from groups within that population are compared.

An exercise device that uses cycling to measure physical work.

The physiological factor that is allowed to vary as another factor (the independent variable) is manipulated. Usually plotted on the y-axis.

Fluctuations in physiological responses that occur during a 24 h period.

A relationship between two variables in which one changes predictably as the other increases or decreases.

Study of the effects of the environment (heat, cold, altitude, hyperbaria, etc.) on the function of the body.

An exercise device that allows the amount and rate of a person's physical work to be controlled (standardized) and measured.

The study of how body structure and function are altered by exposure to acute and chronic bouts of exercise.

Maintenance of a constant internal environment.

In an experiment, the variable that is manipulated by the experimenter to determine the response of the dependent variable. Usually plotted on the x-axis

A research design in which subjects are tested initially and then one or more times lter to directly measure changes over time resulting from a given intervention.

The study of the function of organisms.

The group in an intervention study that recei9ves a placebo rather than a test substance.

The application of the concepts of exercise physiology to training athletes and enhancing sport performance.

Physiological adaptation to repeated bouts of exercise.

An ergometer in which a motor and pulley system drive a large belt that a person can either walk or run on.
