SDSU ENS 331 Exam 3 Practice
Questions With Solved Solutions.
Muscular Endurance - Answer the repetition of submaximal contractions or submaximal
holding time (static or isometric endurance), stamina through repetition-needed for work, sport
and activities of daily living
factors influencing strength - Answer Sex/gender differences
Age-strength declines slowly and increases after 55y/o
Muscle fiber types: fast twitch, slow twitch
Muscular Strength - Answer The maximal force that can be exerted in a single voluntary
contraction
How does one achieve muscular endurance? - Answer Repetitive contactions of muscle fibers
(need continuous supply of energy)
What types of muscle fibers are best for building muscular endurance? - Answer Slow
oxidative fibers
Fast Oxidative-Glycolytic fibers
Flexibility - Answer the range of motion through which the limbs are able to move
speed - Answer rapid acceleration
power - Answer strength(force) + speed
agility - Answer ability to change position and direction rapidly
, Why are core muscles important? - Answer Core muscles are used for stabilization
overload principle - Answer For improvements to happen, workloads have to impose a
demand(overload) on the body
About 2/3 maximal force
improvements related to intensity, duration, and frequency of training
What does overloading do in terms of strength - Answer increases size of muscles because of
increases in contractile proteins and tougher connective tissue
What does overloading do in terms of muscular endurance - Answer improve aerobic enzyme
systems, more mitochondria, and more capillaries
fiber type transformation - Answer people with a higher percentage of fast-twitch fibers have
grater potential for power development
static (isometric) training - Answer same as static strength, max force exerted against an
immovable object
ex rock climbing
dynamic (isotonic) training - Answer contraction against a constant resistance like weight
lifting free weights or weight machines
isokinetic training - Answer max force that can be generated at any set speed
static stretch - Answer slow and constant stretch with end position held for 30 seconds
ballistic stretch - Answer stretch involving bouncing-type movements which the end position
wont be held
