HPEX 310: Exam 1 Questions With Complete Solutions
___% of people will experience LBP
___% americans will be disables by LBP in their lifetime
Correct Answer 80%
15%
2 main ways CHO are supplied to muscle Correct Answer 1.
blood glucose
2. glycogen (storage form of glucose)
most anaerobic ATP production comes from glycolysis
produces quick energy AFTER ATP-PC System for intense
exercise under 2 minutes
2 physiological factors that determine the amount of force a
muscle can generate Correct Answer 1. size of muscle (primary
factor)
-larger muscle, greater force
2. number of muscle fibers recruited during a movement
-the more fibers that are stimulated, the greater the force
generated
2 types of isotonic contractions Correct Answer concentric and
eccentric
4 major factors that influence health and longevity Correct
Answer lifestyle: diet and exercise, smoking (most influential)
environment: food deserts, air quality
genetics
health care delivery
,5 structural limitations to movement Correct Answer 1. the
shape of bones/type of joint (ball and socket vs hinge)
2. stiff muscles
3. connective tissues (ligaments & cartilage)
4. tendons
5. tight skin
adaptations to resistance training Correct Answer -faster fiber
recruitment
-hypertrophy: increase in muscle size due to fiber size increase
aerobic energy production Correct Answer exercise > 1 min,
takes time to get going
requires oxygen to make ATP
CHO, fats, proteins can all be used to make ATP
exercise > 20 mins --> gradual shift from CHO to fats as fuel
age predicted max HR formula Correct Answer THR =
(MaxHR) x (Desired Intensity %)
anaerobic energy production Correct Answer high energy
phosphates: first to make ATP, fastest to make ATP, first to run
out
ATP --ATPase--> ADP + Pi + energy
PCr + ADP --creatine phosphate--> ATP + Cr
avoiding injuries Correct Answer do not hold your breath
do not fully extend knee, neck, or back
, do not stretch muscles that are already stretched
do not stretch to the point of pain
ballistic stretching Correct Answer a series of quick, bouncing-
type stretches
barriers to changing lifestyle Correct Answer lack of
knowledge
lack of motivation
denial
low self-efficacy
lack of support
time
family commitments
benefits of being physically active or exercising Correct
Answer decreased fall risk
decreased risk of early death
decreased anxiety and depression
improved cognitive function
improved mood
decreased risk of strokes, cancers, CVD, osteop
benefits of flexibility Correct Answer increased joint mobility
more efficient body movement
better posture
prevents LBP
benefits of good posture Correct Answer minimizes joint wear
and prevents arthritis
reduces stress on spine ligaments
