An exercise dose is described by four distinct variables. Name and define them.
F- frequency - how often an activity is done. This can be expressed in days per week or number of times per day. I- intensity- how hard the activity is. Intensity can be described in terms of %VO2 max, %maximal HR, RPE, and LT. T- time- the duration of the activity. This is typically expressed as the number of minutes of activity. T- type- the mode or kind of activity done. This could simply refer to whether the exercise is resistance versus cardiorespiratory endurance, or within the latter, swimming versus running versus rowing.

In regard to vigorous-intensity physical activity, what is the amount of physical activity recommended for realizing substantial health benefits?
75 min per wk of vigorous-intensity physical activity
Briefly define the public health recommendation for physical activity for (a) moderate and (b) vigorous physical activity.
A- moderate physical activity: 150 to 300 minutes of moderate-intensity activity per week. (also 2 days per week of resistance training). B- vigorous physical activity: 75 to 150 minutes of vigorous-intensity activity per week. (also 2 days per week of resistance training).
Briefly define what an adverse event is, and list three distinct steps to take in order to minimize them.
Adverse events are injuries or medical complications that can result from an increase in physical activity levels. Three distinct steps to take in order to minimize them are: 1. screen individuals using health-risk questionnaires 2. measure important physiological variables at rest before taking exercise tests 3. gradually progress a sedentary person through a physical activity program
A client tells you that he will be leaving his home (at 1,200 ft [366 m] of elevation) and traveling to an altitude of 8,000 ft (2,438 m) to do some hiking. He wants to know what he should expect in terms of his response to exercise and whether or not you have any special instructions for him. What do you tell him?
At this elevated altitude, he should expect higher HRs at the same work intensity due to the lower partial pressure of O2 at that elevation. He may find that he cannot maintain the same intensity of hiking at this altitude, and he should decrease his intensity if needed. He will need to maintain hydration status as well because the dryer, cooler air will facilitate evaporation of fluid even in cooler temperatures.
Explain the 2014 edition of the ACSM Guidelines acronym FITT-VP.
F- frequency - how often an activity is done. This can be expressed in days per week or number of times per day. I- intensity- how hard the activity is. Intensity can be described in terms of %VO2 max, %maximal HR, RPE, and LT. T- time- the duration of the activity. This is typically expressed as the number of minutes of activity. T- type- the mode or kind of activity done. This could simply refer to whether the exercise is resistance versus cardiorespiratory endurance, or within the latter, swimming versus running versus rowing. V- volume- product of frequency x intensity x time. P- progression- transitioning from easier to harder exercise over time.
How has the focus of the physical activity guidelines shifted over the past 40 years?
In the 1970s the guidelines focused on fitness. From the late 1970s to mid-1990s the guidelines focused on public health outcomes, and now in the 2000s the guidelines are focused on preventing and reducing obesity.
A client hands you the results of a graded, submaximal treadmill test that was taken at another facility. Using the data from this test and the ACSM metabolic equations, her VO2 max was predicted to be 48.3 ml · kg-1 · min-1. She informs you that she was allowed to hold on to the treadmill railing throughout the test. With this in mind, what conclusion would you most likely come to regarding the accuracy of her predicted VO2 max? Be specific in your answer.
It is most likely overestimated because holding on to the rails during testing lowered the work output required from her at all stages of the test. This allowed her to continue with the test for longer than if she had not held on to the rails. The ACSM formula assumes that the client is not allowed to hold on to the rails during testing. Separate formulas exist to calculate the VO2 max values for individuals who use the rails during testing.

How does regular physical activity influence the leading cause of death?
Regular physical activity reduces the risk of heart disease by lowering blood pressure (BP), improving the lipid profile, and increasing CRF.
How does a fitness professional choose a preactivity screening questionnaire?

When estimating the total oxygen cost of walking up a grade, what variables do you need to add together?
You add the net oxygen cost of the horizontal walk (one component) to the net oxygen cost of the vertical (grade) walk (one component) to the resting metabolic rate (one component), which is taken to be 1 MET (3.5 ml · kg-1 · min-1).
A client completes an exercise session by working at a 3 MET level on an arm ergometer. The following day, he works for the same duration at a 3 MET level on a leg cycle ergometer. Would you expect a higher or lower BP and HR response while working on the arm ergometer?
higher
