What is acute exercise
An individual bout of exercise along with the responses to that exercise bout are referred to as acute responses. When examining the acute response to exercise, we are concerned with the body's immediate response to and sometimes its recovery from, a single exercise bout.
What is chronic adaptation
How the body responds over time to the stress of repeated bouts of exercise.
What is an ergometer (ergo=work; meter=measure)
It is an exercise device that allows the intensity of exercise to be controlled (standardized) and measured.
Why is a treadmill the equipment of choice
They are chosen by most researchers and clinicians, particularly in the U.S. With these devices, a motor drives a large belt on which a subject can either walk or run; thus these ergometers are often called motor-driven treadmills.
Why are cycle ergometer used
For many years, primary testing device. Still used extensively in both research and clinical settings. They can be designed to allow subjects to pedal either in the normal upright position (using mechanical friction or electrical resistance) or in reclining or semi-reclining positions.

What is cross-sectional research design
A cross section of the population of interest (that is, a representative sample) is tested at one specific time, and the differences between subgroups from that sample are compared.
Refers. Pg. 16
What is longitudinal research design
The same research subjects are retested periodically after initial testing to measure changes over time in variables of interest.
Refers. Pg. 16 / 17
What is a controlled group, when dealing with reserach
This group acts as a comparison group to make certain that any changes observed in the running group (example) are attributable solely to the training program and not to any other factors, such as the time of the year or aging of the subjects during the course of the study.
Often serves as a "time control," accounting for nonexperimentally induced changes that may occur over the course of the study period.
What is a Crossover design
Each group undergoes both treatment and control trails at different times. (Ex. Pg. 18)
