Q

Energy Balance

A

Ratio of caloric ingestion to caloric expenditure

21
Q

If caloric expenditure is greater than caloric ingestion=

A

loss in body mass

22
Q

If caloric expenditure is less then caloric ingestion=

A

gain in body mass

23
Q

What does total caloric expenditure equal?

A

resting metabolic rate (RMR) + caloric expenditure of physical activity

24
Q

Dieting and Weight Loss Guidelines

A 
Drink sufficient water
Make sensible fat choices
Minimize empty calories
Do not reduce calories too drastically
Keep portions small
25
Female Athlete Triad
Syndrome consisting of 3 interrelated conditions affecting female athletes & active women
26
What composes the female athlete triad:
Menstrual cycle irregularities Osteoporosis Eating disorders: anorexia nervosa & bulimia nervosa
27
Work=
force × distance
28
Unit of measurement for work
joule (J) 1 Newton (N) of force over 1 meter Kilopond (Kp) Kilogram-meter (kgm
29
Power
rate at which work is performed | force × distance/time (velocity)
30
Units of measurement for power:
watts (W) | 1 W = 1 J/s
31
Min. VO2max needed for living
13 mL·kg·min-1
32
Continuous
intensity is increased in stages with no breaks
33
Discontinuous
intensity is increased in stages with breaks
34
Types of protocols in order of decreasing VO2max:
Graded running test Running test at 0% grade Walking test
35
Balke test
initial low workload w. gradual increase
36
Bruce protocol
speed & grade are changed every 3 min
37
HR has general linear relationship to
Mechanical power output Workload Exercise intensity
38
Test Termination Criteria
Angina or chest pain indicating myocardial ischemia Abnormal blood pressure response Abnormal ECG response Discomfort or pain in extremities indicating intermittent claudication Dyspnea, or difficulty in breathing Dizziness or syncope
39
20-meter shuttle run test
Run back & forth btw 2 lines 20 m apart at increasing velocities until volitional fatigue
40
Cause of excessive rate of lactate release
Greater reliance on carbohydrate instead of lipid metabolism Recruitment of fast-twitch muscle fibers Stimulation of sympathetic nervous system
41
Wingate test
30-second sprint test on cycle ergometer
42
Margaria step test
running up staircase as fast as possible
43
Anaerobic treadmill test:
running at 20% grade & 8 mi·hr-1
44
Factors Affecting Anaerobic Power and Speed Tests
``` Motivation to perform at one’s best Skill at performing movements Degree of coordination Muscle-fiber-type composition Body composition ```
