Chapter 13: Nutrition and Physical
Activity Exam Questions and
Answers 100% Pass
physical activity - ✔✔any muscle movement that increases energy expenditure
leisure time physical activity - ✔✔any activity unrelated to a person's occupation
e.g. giving, walking, biking
includes exercise - purposeful, planned, physical activity
physical fitness - ✔✔state of being which is created by the interaction between nutrition
and physical activity
physical fitness includes: cardiorespiratory fitness, musculoskeletal fitness, flexibility,
body composition
cardiorespiratory fitness - ✔✔-determines how long you can continue a task, whether it
is climbing stairs, raking leaves, or running a race
-requires strength but also involves the cardiovascular and respiratory systems

,musculoskeletal fitness - ✔✔-muscle strength and endurance enhance the ability to
perform tasks such as pushing or lifting
-increased by repeatedly using muscles in activities that require moving against a
resisting force
-strength training or resisting training (weight lifting)
flexibility - ✔✔-determines range of motion
-being flexible may reduce the risk of pulled muscles and tendons
body composition - ✔✔-exercise builds and maintains muscle
-individuals who are physically fit have a greater proportion of lean body tissue than
unfit individuals of the same body weight
overload principle - ✔✔the more you do, the more you're capable of
what region in Canada has the most physically active population? least? - ✔✔most is
BC
least is manitoba and maritimes
what diseases are strongly affected by physical inactivity - ✔✔osteoporosis, stroke, type
2 diabetes, heart disease, colon cancer, breast cancer, hypertension

, what gender is more physically inactive? - ✔✔females
eating for exercise is an issue of: - ✔✔fuel, hydration, nutrients
What is the fuel for physical activity? - ✔✔ATP
Adenosine triphosphate (ATP) - ✔✔-the energy carrying molecule in the body
-ATP must be generate continuously since muscles have only enough ATP for 1-3
seconds of activity
-ATP provides energy for all body processes
What do muscles do after depleting ATP stores? - ✔✔they turn to other sources:
-Creatine phosphate (CR) stores some energy that can be used to make ATP
- Creatine phosphate stores enough energy for 3-15 seconds of maximal physical effort
(e.g. sprinting, jumping, for very brief periods of time)
During first 15s of exercise, what fuel is used? What happens after that? - ✔✔-ATP in
muscles is used for the first 1-3 s of activity
-then for the next 8-10s Phosphocreatine stores are used
-after the creatine phosphate stores have been used up, the lungs still haven't had
enough time to produce O2 so anaerobic metabolism must occur, this lasts for the first
2-3 min of exercise
