Exercise Prescription for CR Fitness Flashcards
dose is characterized by… (4)
the intensity, frequency, duration, and type of activity
Dose-Effect Curve
helps fitness professional determine the proper “dose” of exercise to bring about (or increase the likelihood of) a desired “effect” (response)
components of the dose-effect (5)
potency slope maximal effect variability side effects
potency
the “potency” of exercise is relatively unimportant as long as the “dose” is appropriate
slope
describes how much of an effect comes from a change in dose
maximal effect
the maximal effect of exercise varies with the type (dosing) of the exercise
variability
these is considerable variability in the response to exercise between individuals
variability is +- error
side effect(s)
side effects to exercise might include an increased risk in injury
implications of dose-effect curve
@ plateau of dose-effect curve, more is not better
in fact, it increases the chance of injury
types of responses to exercise (4)
acute responses
rapid response
linear response
delayed response
acute responses to exercise
responses occur with one or several exercise bouts but do not improve further
rapid response to exercise
benefits occur early and then plateau
linear response
gains are made continuously over time
delayed response to exercise
responses occur only after weeks of training
Does-Response curves vary depending on…
the dose, the effect (response) measured, and the relationship examined
this makes it difficult to provide a single exercise prescription that addresses all issues to preventing various diseases
