Q

What is the range for vigorous intensity with %HR max

21
Q

What is the equation for HRR

A

HRmax - HR rest

(220-age) - Resting heart rate

22
Q

What is the difference behind using HRR instead or HR max when finding THR

A

HRR is more individualized to the person regardless of their current health status.

23
Q

What is the equation for finding THR by using HRR

A

THR = (HRR) x % of intensity + HR rest

24
Q

What is the range of HRR using light intensity

25
What is the range of HRR using moderate intensity
40-59
26
What is the range of HRR using vigorous intensity
60-89
27
Find the THR of a 40 y/o, moderate intensity using HR max
115-137
28
Find the THR of a 40 y/0. moderate intensity using HRR with a HR rest of 60 and 100
HR rest of 60 = 108-131 | HR rest of 100 =132-147
29
A ___ is the average, seated, resting energy cost of an adult
MET
30
1 MET = ___ mL/kg/min
3.5
31
____ levels are the multiples of the resting metabolic equivalent
MET
32
If someone is working at 4 METs, what is the volume of oxygen required by the body
4 METs x 3.5 = 14 mL/kg/min
33
What term is defined as the highest amount of oxygen an individual can take in, transport, and utilize to produce ATP aerobically while breathing air during heavy exercise
VO2max
34
____ = maximal oxygen uptake
VO2 max
35
What is the importance of VO2max
The more efficient the body, the higher VO2 max and level of intensity
36
(relative/absolute) VO2 max takes body weight into consideration
relative
37
How would you convert absolute VO2max to relative VO2max
multiply L by 1000 to get mL and divide weight in pounds by 2.2 to get kg
38
Find the maximal exercise capacity in METs with a patient's VO2 max of 2L x min-1 weighing 200 pounds
6.3 METs
39
What is the VO2 max and VO2 Reserve for someone who has an absolute fitness intensity of 12 METs
``` Max = 42 mL/kg/min Reserve = 38.5 mL/kg/min ```
40
There is a ___ relationship between physical activity and relative risks
dose
41
All healthy adults should participate in moderate intensity for a minimum of ___ minutes ___ days a week or in vigorous intensity for a minimum of ___ minutes ____ day a week
30, 5 | 20, 3
42
Moderate intensity aerobic activity can be accumulated to total the 30 min minimum by performing bouts each lasting _____
equal to or greater than 10 min
43
Every adult should perform activities that maintain or increase muscular strength and endurance for a minimum of ___ days a week
2
44
True or False: varying intensities can be combined to reach the minimum amount of PA needed in a week
true
45
What are the potential benefits of exceeding the recommended amounts of physical activity
Improve fitness, reduce risk for chronic diseases and disabilities, and/or prevent weight gain
46
What are the risks associated with physical activity and exercise
Musculoskeletal injury Sudden cardiac death Myocardial infarction
47
Why is hypertrophic cardiomyopathy a bad thing
An enlarged heart is bad because the walls are thicker and so the amount of blood going in will decrease and decrease efficiency of blood pumped out
48
What are some strategies to reduce cardiac events during vigorous intensity exercise
``` Physicians should know pathologies Patients should be educated on symptoms Athletes should be prescreened Staff should be trained in cardiac emergencies Modify workouts ```
