Calculations

Question 1

cardiac output

Answer 1

CO = HR x SV

average resting HR = 75bpm

Question 2

stroke volume

Answer 2

SV = EDV - ESV

average resting SV = 70ml/beat

Question 3

blood pressure

Answer 3

BP = CO x total peripheral resistance (TPR)

Question 4

pulse pressure

Answer 4

PP = systolic pressure - diastolic pressure

Question 5

mean arterial pressure

Answer 5

MAP = diastolic pressure - 1/3 pulse pressure

Question 6

pH

Answer 6

pH = -log10[H+]

Question 7

body mass index

Answer 7

BMI = weight/height^2

Question 8

target heart rate

Answer 8

THR = % (MHR-RHR) + RHR

Question 9

maximum heart rate

Answer 9

MHR = 220 - age

Question 10

ideal/predicted mass

Answer 10

ideal mass = (100-fat% / 100-normal%) x weight

normal fat% for males = 15%
normal fat% for females = 20%

Question 11

oxygen uptake

Answer 11

oxygen uptake = METS x 3.5 x weight

max resting oxygen uptake = 3.5ml/min/kg muscle mass

Question 12

energy expenditure

Answer 12

energy expenditure = METS x 0.0175 x weight

Question 13

relative strength

Answer 13

relative strength = weight lifted / body weight

Question 14

skinfold

Answer 14

male = sum of 6 skinfolds x 0.1051 x 2.585
female = sum of 6 skinfolds x 0.1548 x 3.58

Question 15

VO2max

Answer 15

VO2max = HRmax x SVmax x a-vO2
