Question

James is a 32-year-old healthy male with a resting heart rate of 65 beats per minute who wants to train at 75% to 85% of his heart rate reserve. Show your calculations.

a. What is his age-related maximal heart rate?

b. What is his heart rate reserve?

c. What is the lower target heart rate limit?

d. What is the upper target heart rate limit?

Answer #1

A. Age related maximal heart rate = subtract age from 220

= 220 - 32

= 188

B. Heart rate reserve (HRR )= Heart rate (max) - heart rate (rest)

HR ( max ) = 220 - 32 = 188

Subtracting age from classic karvonen formula ( 220)

Heart rate reserve (HRR ) = 188 - 65 = 123

C. Lower target heart rate limit = Multiplying the maximum heart rate by 75 percent

Ie , 188 × 0.75 = 141

D. Upper target heart rate limit = Multiplying the maximum heart rate by 85 percent

Ie , 188 × 0.85 = 159.8

Using the Karvonen Formula Worksheet provided list your Target
Training Heart Rate in beats per minute (BPM) for the following
zones:
50%=66 RHR, 65%=61 RHR, 75%=70 RHR, 85%=66 RHR & 95%=62
RHR
Age: 24
Avg. Resting Heart Rate: 66
Target Training Heart Rates:
50% = 128 BPM
65% = 145 BPM
75% = 156 BPM
85% = 168 BPM
95% = 179 BPM

for a 65 year old with a resting heart rate of 64, the
calculated Threshold and Upper Limit heart rate, using 65% and 80%
would b

Consider a sample of resting heart rates in beats per minute
given by members of this class: 55, 70, 80, 72, 90, 65. ] (a)
Compute the sample mean resting heart rate of these 6 students. Do
not use statistical features of your calculator. Be sure to use
appropriate notation. (b) Compute the median resting heart rate of
these 6 students. Do not use statistical features of your
calculator. (c) Compute the sample standard deviation resting heart
rate of these...

A random sample of 33 students have a mean resting heart rate of
71.12 beats per minute and standard deviation of 13.05 beats per
minute.
(a) What is a point estimate for the mean resting heart rate of
the students?
(b) Verify the two requirements for constructing a confidence
interval are satisfied by this problem
(c) Determine and interpret a 95% confidence interval for
resting heart rate of the students. Do not use the T-Interval or
Z-Interval features of your...

The resting heart rate for an adult horse should average about
μ = 42 beats per minute with a (95% of data) range from 18
to 66 beats per minute. Let x be a random variable that
represents the resting heart rate for an adult horse. Assume that
x has a distribution that is approximately normal.
(a) The empirical rule indicates that for a symmetrical and
bell-shaped distribution, approximately 95% of the data lies within
two standard deviations of the...

The maximum heart rate, in beats per minute, that you should
achieve during exercise is 220 minus your age,
220 minus a220−a.Your exercise goal is to improve cardiovascular
conditioning. Use the following formulas to answer parts a and
b.
Lower limit of range
Hequals=seven tenths left parenthesis 220 minus a right
parenthesis710(220−a)
Upper limit of range

1. The heart rates (beats per minute) of 20 people are as
follows:
60 60 65 66 66 67 70 72 75 76 76 77 80 80 81 82 82 84 85 86.
(a) Calculate the percentile rank for a person with a
score of 80.
(b) What does the percentile rank from (b)
mean?

A 45-year-old male performed a maximal exercise test. His max
VO2 was 40 ml/kg/min, and his highest HR was 186 bpm. Resting heart
rate is 70 bpm. To exercise at 50-55% heart rate reserve, which of
the following is his target heart rate range?
A) 88-96 bpm
B) 93-202 bpm
C) 128-134 bpm
D) 123-128 bpm

A 65-year-old man presents to a neurologist complaining of a
resting tremor. He is accompanied by his wife, who points out that
her husband has been moving much more slowly, he has not been
sleeping well, and has been depressed and anxious. During the
interview, the patient speaks in a low tone without facial
expression, and his left hand has a resting tremor involving the
fingers and wrist. Physical examination reveals a wide, shuffling
gait without arm swing. Passive movement...

Mr. James is 62-year-old African-American male with a past
medical history of gout, type II diabetes mellitus, and high
cholesterol. His father passed away at the age of 60 from a
myocardial infarction; his mother is still alive and well. When he
was 59, he underwent surgery for a left knee replacement. Since he
turned 60, Mr. James has taken an active role in improving his
health. He follows a low-fat diet, and enjoys a daily walk with his
wife...
